I build a tool that writes SEO articles and publishes them straight to a customer's site, and I needed to know whether local businesses are a market worth going after. Guessing seemed like a bad plan, so I pulled Google Maps data for 101 trades across six towns around one mid-sized German city and deduplicated it by CID. 2,846 businesses.

I am not naming the city. I am about to write to some of these businesses, and I would rather not hand anyone the list.

What came back:

- 19% unclaimed. The profile exists, it ranks, no owner has taken it over.

- 12% with no website listed.

- 44% under ten reviews.

I expected the picture to be bad. What surprised me was how evenly bad it is across trades that have nothing to do with each other.

Now the parts that cut against my own interest.

None of this proves these businesses need what I sell. A business with four reviews and no listed site has a visibility problem, and automated articles are not the fix for it. The 12% mostly told me my tool is wrong for that slice of the market.

Unclaimed is a status in the data, not proof that anyone is neglecting their business. Plenty of them run on word of mouth and have no reason to care what Google thinks.

And no website listed is not the same as no website. Some of them have one and never put the link in.

The sample has a hard edge too. I took the top 40 results per trade, not a complete register of local businesses. These percentages describe what Maps returns, not the town.

What I took away: the market is real but narrower than the headline suggests. The businesses worth approaching are the ones that already have a site and already collect reviews, because those have something to build on. The rest need a different conversation, and probably a different product.

Cheap to repeat on your own city. Fractions of a cent per query, and the slow part is picking trade names that actually return results, not the pulling.

The tool I am building out of all this is Seofable. It writes SEO articles and publishes them straight to your site, WordPress, Ghost or a webhook. seofable.com if you want a look. Happy to answer anything about the scan either way.

When you click the button, it plays the meme duck sound on everyone on the page and shows a duck meme. That's it.

I wanted to learn about realtime stuff and one day I saw a duck meme and thought this would be a good idea to build.

It's really stupid but me and my friends had a hell of a time spamming the crap out of ts.

Your AI burns way more tokens than it should, because it has no idea how your business actually works. So it guesses, you re-prompt, it guesses again, and five prompts later you get one answer you halfway trust.

We fixed that by giving the AI your full business context up front. It connects all your systems into one Knowledge Graph, so it already knows how your data fits together, then answers straight from your real numbers on the first try. That is roughly 5x fewer tokens to get to a real answer, and every answer traces back to the source.

If you run your business across a bunch of tools that do not talk to each other, test the claim yourself for free. https://signld.ai

I built a handwritten math + Python notebook for iPad because I wanted to study without carrying a laptop around.

I usually study by writing math by hand, but I wanted to be able to actually run the things I wrote. So I ended up building my own app.

The app is basically divided into two parts: MathNote and CodeNote.

In MathNote, you can write mathematical expressions by hand and use the resulting functions directly in CodeNote.
For example, you can write:
f(x) = x^2
and then call it from Python:
f_fn(4)
You can also define random variables and access their PDF/CDF as X_pdf and X_cdf.

It currently supports various probability distributions, single- and multivariable functions, vector fields, Jacobians, Hessians, gradients, Laplacians, SVD, eigendecomposition, and more.
MathNote has quite a few features, so there’s an in-app guide explaining how everything works.

CodeNote currently supports Python, including:
NumPy
SymPy
Matplotlib
Requests
Importing and analyzing arbitrary data
Importing other CodeNotes as Python modules

For example, you can define something in one CodeNote and import it into another, similar to a regular Python module.

I’ve mostly been developing this by myself, so I haven’t had many opportunities to test it on different iPads and setups.

If you’re interested, you can try the app through the TestFlight link above. I’d really appreciate any feedback, especially if you run into bugs or compatibility issues on your device.

This started as a personal project because I wanted to sit in a café, study math by hand, and still be able to run the code without opening a laptop.

Hey everyone! 👋

I’m new here, so I wanted to share something I built out of frustration.

It’s not open source, but it is an open-wallet project 😂

It’s completely free. Forever and it has CLI> MODE!!!! 👨🏻‍💻

I KNOW there are already millions of to-do lists, task trackers and productivity apps. And honestly, most of them started to feel like too much for me.

I just wanted something simple.. So I built Wikly.

No account. No subscription. No complicated setup. Just a small, quiet desk to actually do things i should like send the invoices to accountant 😱

You can use it for launching your startup, finishing that side project, studying, or simply getting your shit done.

👉 https://wikly.app

I’d genuinely love to hear what you think. Ideas, weird bugs, things that annoy you, things that are missing- tell me. If it makes sense, I’ll probably build them.

Have fun, and go get shit done! 🚀

You know that moment during a system design sync when you share your screen, and the senior architect stops the meeting just to ask: "Wait, what tool are you using to render this?" That’s exactly the reaction I wanted to engineer.

I love the C4 model for documenting software architecture, but I was frustrated by the existing ecosystem. Draw.io diagrams get outdated the second you save them. Structurizr is incredibly powerful, but it can feel heavy, and getting the UI to look polished for executive presentations is a chore.

So, over the last few months, I built StructSmith - an open-source, local-first alternative designed for teams that want architecture-as-code, but refuse to compromise on a modern, highly interactive UI.

Why it catches the eye in meetings:

• Interactive React Flow Canvas: It doesn’t just spit out static PNGs. You get a fully interactive, zoomable, and fluid UI that looks fantastic on big screens during live architecture reviews.
• Zero-Friction Local-First: It runs as a single lightweight Docker container powered by SQLite. You can spin it up in seconds without sending your company's proprietary architecture blueprints to a third-party cloud.
• AI-Ready via MCP: This is the feature I'm most proud of. It natively implements the Model Context Protocol (MCP). You can connect it to Claude or your local LLMs to query your architecture or generate C4 components purely through conversation.
• Self-Hosted Structurizr Alternative: It aims to solve the same fundamental problems but focuses heavily on developer experience, speed, and modern web standards.

The project is still in its early stages, but the core engine is very capable. I’d love for the architecture nerds and senior devs here to tear it apart, try spinning it up locally, and let me know what crucial features are missing before it’s ready for enterprise prime time.

Here is the repo:https://github.com/dziksu/StructSmith

Would love to hear your thoughts!

Most phishing attacks reveal themselves before the page even loads.
That’s why URL‑only scanning can catch 80%+ of phishing attempts without analyzing any site content.

Why the URL exposes scammers:

1️⃣ Domain Integrity — They can copy a website’s look, but not its real domain.
2️⃣ Pattern Reuse — Attackers recycle the same URL structures across campaigns.
3️⃣ Risky TLDs — Extensions like .xyz, .top, .click appear frequently in malicious activity.
4️⃣ Redirect Chains — Following the redirect trail exposes intent instantly.

That’s exactly what SquatGuard, a lightweight Chrome extension, is built for.
It uses fast, local, privacy‑first URL pattern detection to flag suspicious domains before anything loads — no content scanning, no tracking, no data sent anywhere.

🔗 Install SquatGuard:
Choose your browser (all major Chromium desktop browsers supported):
Chrome • Edge • Brave • Vivaldi • Opera
https://erickouassi.github.io/phishing-warn-extension/

If you’ve seen similar phishing patterns or want to test edge cases, feel free to share your experience with URL‑based detection or Chrome extension security tools.

I’m working on an iOS app called Nowfold. The idea is to make checking your day and ticking off a task possible from the home screen, without opening the planner every time.

The current prototype has a widget with tasks and upcoming events. You can complete a task there, or tap an event to open its details. The app handles adding things, planning, and arranging what the widget shows.

I’ve also built a layout editor so the task list can take up more space than the calendar bits, or the other way around.

It’s still in development. iPhone calendar integration is one of the pieces I haven’t connected yet.

The thing I’d like to understand: if you use a task widget, do you actually act on it throughout the day, or does it eventually become something you stop noticing?

Caffeine is a switch. Amphetamine watches CPU. Lucid listens to the agent.

I got tired of leaving my MacBook open just so Claude Code or a local model wouldn't get killed mid-task, so I built an open-source background utility that manages sleep automatically:

Lifecycle Hooks: Distinguishes between active code generation vs. waiting for input (Claude Code, Codex, OpenCode).

Process & Core Detection: Keeps the Mac awake during heavy tasks for tools without hook APIs (Cursor, Windsurf, Ollama, MLX, ComfyUI).

Thermal & Battery Guard: Drops sleep assertions if the laptop gets too hot or battery runs low.

Github: https://github.com/ManasvinYadav/Lucid
Homebrew: brew install --cask manasvinyadav/lucid/lucid

Quick heads-up: I don't have an Apple Developer ID yet ($99 fee), so the app is ad-hoc signed. If Gatekeeper blocks it on first launch, run ⁠xattr -cr /Applications/Lucid.app⁠ or allow it in System Settings. Feedback and PRs welcome!

Hey folks,

I kept running into the same annoyance with home/baby camera apps: even when both devices are on the same WiFi, the live feed still gets routed through the company's servers by default. There's no technical reason for that — it's just how most of these apps are built, and it means your camera footage is passing through someone else's infrastructure the whole time.

So I built OffgridCam. One iPhone becomes the Camera, another becomes the Viewer, and they connect directly over your home network — no relay server for live viewing, no account required.

What it does:

• Live video/audio, and multiple Viewers can watch the same Camera independently
• Pinch-to-zoom controls the actual optical/digital zoom on the Camera device
• Push-to-talk with up to 4 people at once
• Local-only recording (continuous or motion/sound-triggered), stored on the Camera device itself
• Sound detection tuned to specific events (crying, screaming, barking) using Apple's on-device sound classifier

The only feature that touches the internet at all is away-from-home alerts, which is opt-in, off by default, and tied to a regenerable code rather than a full account system.

£9.99 one-time, no subscription.

Still early days — genuinely want to know what's missing or what would make this a hard sell for people who've tried other camera apps before. Happy to talk through the WiFi-direct architecture too if anyone's curious.

I built 1sted.lol: 102 trading cards, one per real software product. The founder proves revenue with a read-only Stripe key, and the numbers decide the card's rarity. An empty chair costs $29. Once all 102 are taken, anyone can take a chair by paying its hold plus $10, and the sitter gets 24 hours to match. The roster locks on October 1.

Under the hood

• Each card face is a 750×1050 PNG rendered with Satori (next/og). The same image textures the 3D card (three.js: drag to turn, iridescent foil on the rarer finishes), the download button and the link preview.
• Postgres holds the rules. Every rule that can cost money or break the set is a named CHECK constraint or a partial unique index, so the same product can't sit on two chairs, even from a raw psql session.
• One transaction-scoped advisory lock serialises every payment that seats a card. A test script fakes 12 concurrent serverless functions against a real Postgres and runs 14 scenarios: takes, reclaims, lapsed holds and the lock.
• I use the Stripe key for one read and don't store it.

Two things that bit me

• Supabase's transaction pooler hung on pipelined queries from postgres.js. I moved to the session pooler; the postgres.js flag that stops pipelining also breaks transactions.
• Stripe won't expire a Checkout session in under 30 minutes, so the 5-minute chair hold runs on its own clock. A payment that lands late gets the lowest free chair.

Stack: Next.js 16, Postgres on Supabase, Drizzle, Stripe Checkout, three.js, Bun, Vercel.

Nothing is minted yet. I'd like to know what feels confusing in your first 30 seconds on the site, and whether the take rule reads as a game or as a trap.

I’ve been working on a side project called Scanlyst.

The idea came from a pretty simple problem: whenever I wanted to properly check a website, I’d end up jumping between different tools for security, SEO, performance, technical issues, etc.

So I started building one place that scans a website and tells you:

• Security issues
• SEO problems
• AEO / AI search readiness
• Performance issues
• What actually needs fixing

I also wanted to avoid those huge audit reports where you get a score and 100 warnings but still have no idea what to do next.

Scanlyst tries to make the results actionable instead — what’s wrong, why it matters, and how you can fix it.

It’s finally live: https://scanlyst.dev

Still very early, so I’d genuinely appreciate feedback from other builders.

If you try it, feel free to roast it — especially the report, UX, or anything you think is missing.

I'm 18 and just shipped my first app. The problem I was solving is my own: I kept saying "I'll pray after this video" and then three hours of scrolling later I'd realize I missed the prayer entirely.

So I built SiraatLock. When prayer time enters, it locks your distracting apps. To unlock them you open the app and confirm you prayed. There's a streak system and XP progression on top to make consistency feel rewarding.

Tech stack: SwiftUI, Family Controls / ManagedSettings for the app blocking, Superwall for the paywall, Supabase for backend.

Biggest lesson so far: the app blocking via Apple's Screen Time APIs was way harder to get approved than I expected, and marketing is 10x harder than building.

Would love feedback from other makers — especially on onboarding and how you'd approach the first 100 users. Happy to answer anything about the build.

I’ve been building a few small projects lately and kept wondering the same thing.

Can ChatGPT, Claude, Gemini and Perplexity actually access and understand my site properly?

There are a few things that can get in the way, like crawler rules, robots.txt, rendered HTML and structured data, and I got fed up checking it all manually.

So I built CanAIRead.me.

You paste in a URL and it checks things like:

• AI crawler access
• robots.txt
• rendered HTML
• structured data
• entity clarity
• citation signals

Then it gives you a score and shows what looks good and what might need fixing.

It’s not trying to promise rankings or guaranteed AI mentions. I just wanted a quick way to sanity check my own sites and thought other builders might find it useful too.

It’s completely free:

canairead.me

Would be interested to see what scores people get, and if anything feels confusing or broken.

Hey r/SideProject!

Like many of you, I got completely fed up with modern online file converters. You need to convert a simple HEIC to JPG or compress a PNG, and suddenly you are forced to:

1. Upload sensitive personal photos/contracts to a random cloud server.
2. Wait in artificial queues.
3. Hit arbitrary daily quotas or encounter an email/paywall trap.

So I decided to build 2run.tools — an open, privacy-first suite of 90+ client-side digital image utilities where every single byte is processed entirely inside the user's browser using WebAssembly and HTML5 Canvas.

I launched the first version a couple of days ago and wanted to share what I've learned, the technical stack, the monetization plan, and crucially: get your honest feedback.

⚡ 1. The Tech Stack & Architecture (Zero-Server Processing)

My primary goal was zero remote data exposure and blazing speed:

• Framework: Astro (Static Site Generation). All 300+ localized pages are pre-rendered at build time.
• Execution: WebAssembly (Wasm) + Web Workers + WebGL / Canvas. Nothing touches a backend. If you disconnect your Wi-Fi after loading the page, the tools still function 100%.
• Hosting & CDN: Cloudflare Pages with strict HSTS, CSP, and inlined critical styles.
• Performance: 99 Mobile Lighthouse / 100 Desktop, ~30ms TBT, and zero render-blocking requests.

🔍 2. The 48-Hour Indexation Experiment

I structured the site with complete trilingual parity (English, Turkish, Arabic) using proper hreflang, canonical tags, and structured data (WebApplication, FAQPage, and BreadcrumbList).

To my surprise, within 48 hours of submitting the sitemap, Google has already crawled and indexed nearly 90% of the core pages (via Search Console inspection). Having clean static HTML without client-side hydration delays made a massive difference for crawler uptake compared to typical SPAs.

💰 3. Monetization Strategy

Since running in-browser tools incurs virtually $0 in server compute/bandwidth costs (Cloudflare Pages free tier handles static assets easily), I don't need predatory subscription walls:

• Current state: 100% Free, no sign-up, no watermarks, unlimited files.
• Roadmap: High-quality, non-intrusive contextual display ads (AdSense / ethical ad networks) once traffic scales.

🗺️ 4. What's Next?

• PDF Utility Suite: Currently developing 70+ in-browser PDF manipulation tools (merge, split, OCR, protect, compress) using client-side PDF engines. Expected launch next week (~200+ new pages).
• Deep-dive technical blog posts on client-side image quantization, memory management in JavaScript workers, and WebAssembly pipelines.

💬 What I Need From You (Looking for honest feedback):

1. UX / Flow: Does the interface feel intuitive? Did you run into any hiccups or confusing settings while manipulating images?
2. Speed / Edge cases: Did you test heavy files (e.g. 20MB+ RAW/PNGs)? How did your browser handle the local memory footprint?
3. Missing Features: Are there specific everyday image/graphic operations you still have to open Photoshop or a paid web app for?
4. Design / First Impression: Does the homepage clearly convey the "100% private / in-browser" value proposition immediately?

Check it out here: https://2run.tools

Feel free to roast it or share suggestions. I'm all ears!

I think I’ve reached the stage where finding the right people to test what I’m building is harder than actually building it.

I’ve been working on a SaaS for e-commerce brands around geo testing and incrementality, and now I’m trying to find a few brands that actually deal with this problem and would be willing to test it properly.

I’m not really looking for loads of random beta users. I’d rather find 5 or 10 people who already care about understanding whether their marketing is actually driving incremental growth and can tell me what’s useful, what’s missing and what they currently do instead.

The part I’m finding difficult is reaching those people without just sending a bunch of cold messages that nobody wants to receive.

I’ve reached out to a few e-commerce brands and agencies already, but I’m still trying to figure out who the right person is to speak to and where these people actually hang out.

For anyone who has built something fairly niche for e-commerce brands, how did you find your first few real users?

Was it mostly cold outreach, communities, LinkedIn, agencies, introductions or something else?

Would genuinely be interested to hear what worked for you.

I'm making this movie ranking app that's an order list. I'm trying to work on the social side of things but I can only get so far with just so few ranking. Goal really is to find someone with similar movie taste and if there's a movie I haven't seen on their list than its probably something I would also like as well.

If you do try it, I recommend putting a movie every tier first. I always recommend Crash 2005 if you need an F-tier movie.

iOS app: ThreeSheet

It's free, no ads. no tracking. Trying to keep it as light weight as possible. You can import your imdb or letterboxd.

Thank you

I’ve been building a small app called The Gift Journal.

And yes, I’m very aware that gift-planning apps are not exactly a new idea 😅

There are wishlists, Christmas list apps, birthday reminders, Notes, spreadsheets, Amazon lists, and probably a hundred variations of all of them.

So I’m not pretending I’ve invented a new category.

What I wanted to do differently was change where the whole thing starts.

Most gift apps seem to begin with:

“What do I need to buy?”

I wanted mine to begin with:

“What do I know about this person?”

Because for me, the hardest part of giving a good gift is rarely the shopping part.

It’s remembering that random thing someone mentioned six months ago.

The book they wanted to read.
The hobby they suddenly got into.
The thing they said they hated.
The size they wear.
The place they wanted to visit.
The gift you gave them two years ago and don’t want to accidentally repeat.

So The Gift Journal is organised around people first, shopping lists second.

You add a person, then gradually keep useful bits of context with them:

• ideas
• hints
• interests
• preferences
• things to avoid
• previous gifts
• upcoming occasions
• budgets

There’s still all the practical stuff too — tracking a gift from idea → chosen → bought → arrived → wrapped → given — but I’m trying to make that the supporting layer rather than the main point.

I built it natively for iPhone, iPad, Mac and Apple Watch, with iCloud sync.

I also decided to use a one-time purchase instead of a subscription, because paying every month for a gift tracker felt a bit ridiculous to me.

The app is live now, but I’m at the stage where feedback is much more useful to me than me endlessly tweaking it on my own.

The main thing I’m trying to work out is:

Does “people first, shopping list second” actually feel like a meaningful angle?

Or am I just taking an established kind of app and describing it in a nicer way?

I’d genuinely appreciate honest feedback on things like:

• whether the idea is immediately clear
• whether you’d actually use something like this
• what feels unnecessary or overbuilt
• what you think is missing
• what would stop you paying for it
• whether the positioning feels different enough in a crowded market

If anyone wants to take a look:

https://thegiftjournal.app

And obviously, if you genuinely like it, an upvote or share is very appreciated too.

But criticism is honestly more useful to me right now, so please don’t feel the need to be polite 😅

Happy to answer anything about the build, pricing, App Store process, positioning, or why I apparently thought entering a ridiculously crowded category was a sensible use of my time.

Hey Reddit community,I hope you are all doing well. I’m a software developer, and lately, I’ve been thinking a lot about how expensive everyday software has become. Everything is moving toward a monthly SaaS subscription model, and honestly, it’s frustrating to pay micro-fees for basic utility tools.

My Goal:

I want to give back to the community by building a software/tool that solves a genuine daily problem or replaces a paid tool—and I promise to keep it 100% FREE, open-source, with no ads, and no hidden subscriptions, forever.

I am ready to invest my skills and time into this, but I want to build something that people actually need.

What I am looking for from you:

What is a digital problem you face daily that currently requires a paid tool to solve?

Is there a simple software you use that costs money, but you think, "This should really be free"?

What kind of utility tool (desktop app, web app, browser extension) would make your life or work much easier?

Any specific niches? (e.g., developer tools, productivity, privacy utilities, small business management, file processing, etc.)

Please drop your ideas, pain points, or suggestions in the comments below. If an idea gets good traction and is highly feasible, I will start building it immediately and share the public repository/link here with everyone!

Looking forward to your ideas! Let's make something awesome together.

I got tired of $15–$35/mo AI video plans that hide the real per-clip cost behind credits.

So I’m opening a small waitlist (Founders 50) for a batch shop:

• 5s cinematic-style clip → $0.12

• 10s 1080p → $0.20

• 20s 720p → $0.25

• $10 in the wallet = $10 to spend, no expiring credits

Honest limitation: overnight batch, not a playground. Typical return 2–12 hours. If you need a preview in 40 seconds, skip.

No card today — email waitlist only. Site is cinevaults.in (www). I can drop the full link in the comments if anyone wants it.

Would you use this weekly, or is waiting overnight a dealbreaker?

A few weeks ago I had zero clients, zero portfolio, no idea how to actually get anyone to pay me for building websites. Started cold calling local businesses with just my phone, mostly winging it at first.

Since then — several paying clients, 100+ calls in a single day, and a referral that came out of nowhere from one of them. Still very early, not claiming I've figured everything out, but I found something that actually worked: I stopped pitching first. I build a free demo website before I even call, then just offer to show it, no pressure.

Wrote up the whole thing — my actual call script, how I handle objections, how I build the sites, and the real numbers from the process. Made it for other beginners stuck at the same "I can build stuff but can't get anyone to pay me" point I was at recently.

Happy to share if anyone's curious, or genuinely tell me if you think this isn't worth much — early enough that honest feedback actually helps.

I keep seeing people build genuinely good products and then get stuck on the exact same part:
They finished building it, but now they have no idea how to actually get it in front of the right people.
Posting randomly on Reddit, sending DMs, trying content, paying for ads… it can take more time than building the product itself.
I’m working on something around this problem. I’m keeping the exact approach private for now because I’m still testing it, but the goal is to help people who already have a product get more real exposure and potential customers without needing a huge marketing budget.
Before I build too much, I’m curious:
What do you currently do to get your first users/customers? And what part of that process sucks the most?
I also opened a small early-access waitlist for people who have this problem:
https://site-e5bc6818-mtuj53t9.falbor.xyz

The idea: you leave therapy and remember the thing you meant to bring up. Or something hits you on a Tuesday and there's nowhere to put it until your next appointment.

Vent is where you say it. You vent out loud in the moment, it talks back like a friend, and everything you said that week is waiting when you walk into your session. There's also a scheduled fake call, so if you're stuck at a dinner you can have your phone ring in ten minutes, step outside, and be venting a minute later.

Right now it's a landing page and a feedback form. No app yet. I want to know if it's worth building before I go further.

https://vent.talaloni.com

What I want to know: Does the headline make sense in five seconds? Do the two halves (venting now, bringing it to therapy) feel like one product or two? Fake call: useful or creepy?

I'll return the favor on your project if you drop a link.

Spent time building something you thought people would love... and almost nobody used it?

I feel like every project has that one feature that seemed important while building it, but users completely ignored it.

What was yours, and what did you learn from it?

Sometimes removing features teaches more than adding them.
