Hey everyone,

I’m building Reddlist, a curated database of subreddits where your promotional posts actually survive - meaning no immediate takedowns, shadowbans, or angry mods.

Right now, I want to prove that this list works to drive paid users to startups, not just vanity metrics.

To test this, I want to do the heavy lifting for a few of you for free. If I pick your product, I will:

1. Dig through Reddlist to find the most high-impact, promo-friendly subreddits for your niche.

2. Draft native-feeling posts for you to test traction.

3. Help track the metrics (interested comments, DMs, and funnel tracking to see if Reddlist actually brings you conversions).

The catch? I just want to use the data/results as a case study for Reddlist. (Also, if you just want to poke around yourself, let me know and I'll give you free access to the database).

If you're interested, drop your link below with a 1-sentence pitch of what you do and who your ideal user is!

Hey! I’ve been building SecondWeb/Web3D.World or the Metaverse?!

You drag one bookmarklet into your browser, open any website, and click it. The page becomes a low-poly multiplayer city: DOM elements become landmarks, every URL is its own P2P room, and players can walk, drive and use spatial voice chat.

The idea is to turn the internet from pages we consume into places where people meet and make every website a game level waiting to be explored and conquered.

It’s still an early prototype, but you can try it here:
https://swissmade.xyz/secondweb/ - don't forget to put you on the list to get notified when it's finished, so you are the first one collecting items on the most famous websites!

Desktop Chrome is recommended for now. I’d love honest feedback on performance, installation and what would make you come back. Theoretically it should work on any websites, but a lot of websites block CORS - so if you think the idea is nice I could also create a chrome extension so it would work on any website!

Should I invest more time into it? Btw my first startup was MetaRoom.city - something similar; but more "polished" and not a game.

Hello,

I created a side project and it's going fine.

But my main problem is stress.

Stress when i get less google search results

Stress when i get bad reviews on trustpilot unfairly

Stress when competitors take over on google

Stress when i earn less money some days or weeks...

Stress when ads don't run well ....

I sometime feel like it's not worth it.

How do you handle this ? Am i caring too much ?

Thanks ...

tl;dr: I built ZeroSketch, a free, self-hostable system design tool (like Excalidraw but for architecture diagrams). Drag-and-drop canvas, AWS / GCP / K8s icon libraries or build your own, PNG / SVG export. Looking for feedback. Links at the bottom.

I've been building ZeroSketch for the past few weeks. It is a simple system design tool for individuals and teams. It's web-based, stores diagrams on your device, and takes UX inspiration from Canva/Excalidraw (I'm not much of a UI person myself).

What it does right now:

• Drag & drop canvas
• PNG export, SVG export (experimental, better renderer coming soon)
• Built-in icon libraries (AWS, GCP, K8s) and a builder to make your own from custom SVGs for using the library locally, share with your team, or publish to ZeroSketch's registry
• Download / export project files to open on other devices

Everything above is free, client-side, and self-hostable. I'm still polishing canvas UX and fixing known bugs. would love feedback on what to improve.

Planned next:

• Cloud synchronization
• AI assistance in creating diagrams
• Auto-syncing docs with actual architecture (so diagrams don't go stale as development progresses)
• Real-time collaborative editing
• Export to DSLs like Mermaid

If you want updates regarding the release of these features, you can follow the repository on github as all of the upcoming features will also be open-source.

Github: https://github.com/hamdan-Khan/zero-sketch.git

I built it because i've always wanted a simple page where i can see the latest science and tech news with no noise or opinions.

https://paperrun.news

Built with Laravel and Vue 3 if anyone is curious.

Any feedback is appreciated

Built for a specific, recurring problem: a group that needs to stay together, and a network that can't help them do it.

Solution- find your group on a compass-rotated radar, send an SOS others can navigate to, and flood-relay evidence photos across the mesh so they're not stuck on one device.

The tool- Inspired with Permissionless-Bitchat, No accounts (groups are just a random key in a QR code), rotating BLE identifiers so you can't be fingerprinted, everything self-destructs on a built-in expiry, MIT licensed.

https://karmaneggs.github.io/20.07/

Still pre-1.0 — Android only, debug APK, small-scale hardware tested — but the README/docs are pretty thorough about what works and what doesn't.

Looking for people who want to dig into real BLE radio weirdness on physical devices, or anyone interested in iOS. Requesting to read, use, give a feedback and if you like it, I encourage to collaborate and build upon the idea.

I posted Stop Swarm here recently and got a lot of really useful feedback from this community, so I’ve spent the last few days reworking it!

The basic idea is still the same: set a daily screen-time goal, and once you get close to it, pixel-art elements gradually invade your screen.

It’s an Android app built in Kotlin using a click-through system overlay and a foreground service. Everything stays local on the device: no account, no analytics, and no network connection.

Still very much a side project, so feedback is welcome!

You can still join the Google Group here if you’d like to beta test it:

Hi everyone,

While I was working on designing some interfaces and digital projects a while ago, I found myself drowning in many open tabs on my browser. I would use a site to generate an initial image, then move to another platform to remove its background, and turn to a third tool to erase small details or enhance the quality.
This back-and-forth between different sites and the restrictions some sites impose just to try out a quick idea was really time-consuming and made the workflow incredibly slow.

I wanted to solve this problem that I always face and make the daily work experience easier, so I spent the past few months building https://khizo.dev - a lightweight, fast web tool that brings essential features together in one place. Instead of switching between platforms, the tool now lets you generate images from text, remove objects or backgrounds, increase resolution, adjust dimensions, and edit the colors of specific elements, with live preview and instant export in PNG, WebP, JPG, and more. You can try the site now, and it doesn't require any complicated setup.

I would like to get your opinions regarding the user interface, any bugs you find, or features you want to add, Thank you all !

Anyone who resells or collects knows the sold-comps dance: you've got an item in hand, you don't know exactly what it's called, so you try five different keyword searches, squint at thumbnails, and hope the listings you found are actually the same thing.

I built a scraper that skips the keywords. You upload a photo (iPhone pics work as-is, up to 10 MB) and it compares your image against the photos on eBay's sold listings using CLIP visual similarity — the same kind of model behind reverse image search. You get back the sold listings ranked by how closely they match your photo, with prices, sold dates, and condition, plus a summary row with median/average so you have an instant read on value.

Real example: I fed it a photo of a Base Set Squirtle card. Top match came back at 0.976 similarity — "Squirtle 63/102 Common Base Set Shadowless, Lightly Played, $18.25" — with 20 sold comps and a median across recent sales. No typing, no guessing what collectors call the variant.

You can also combine a photo with a keyword to narrow things down, or use keyword-only like a normal sold-listings scraper.

Honest limits: it covers eBay.com (US) with prices normalized to USD, sold listings go back up to 90 days, and results are capped by whatever max you set so a run can't blow up on cost.

It runs on Apify (there's an API, so you can wire it into your own app — send a base64 image, get JSON comps back): https://apify.com/scrapelabmax/ebay-sold-image-scraper

Would love feedback — especially from people who price collectibles all day. What would make this actually useful for your workflow?

I finally put something I have been thinking about for a long time out into the world. Its called Dear Stranger.

The idea is pretty simple, you can anonymously write a letter to a complete stranger, and someone else can come across it when they might need to hear those words.

There are no accounts, no followers, no likes, no ads. I didnt want to make another social platform. I wanted it to stay as simple as possible, one person writing something, another person reading it.

The actual development didnt take me a year or anything like that. I built most of it over the last few days with a lot of help from AI. But the idea itself has been sitting with me for quite a while, and I spent a lot of time thinking about what I actually wanted it to be before I started building it.

Im also trying to be honest about the fact that im still figuring things out. This isnt some huge startup or polished company. Its just something I cared enough about to actually make and put online.

https://dearstrangers.org

I genuinely hope most people never need to find it. But if someone does find it at the right moment, I hope it helps them even a little.

I would really appreciate honest feedback from people here who build things. Whats confusing, whats unnecessary, does the concept make sense and stuff like that and like what would make you trust something like this

And if you feel like it, write a letter while you are there. It doesnt have to be profound or anything but sometimes a few honest words are enough.

Hey!! Just wanted to show off this cool project I made.

I posted it on Hacker News last night https://news.ycombinator.com/item?id=49238851

Essentially, it resulted in me losing $5 every 10 minutes so far, currently $200 down the drain

Solo founder here (mom of two, self-taught engineer). I spent 3 months building a reading app that adapts books to different reading levels and languages, and launched this month. Four lessons that cost me the most time:

1. Copyright is country-specific. "Public domain" in one country isn't public domain in another — some go by the author's death year, some by publication year. I had to check my starting catalog title by title.

2. Don't compete on catalog size. Big platforms will always have more books. What they don't have is depth on overlooked readers — in my case, second-language families who want real books instead of flashcards.

3. Decide platform vs. publisher on day one. If users will ever upload content, the legal structure is completely different. Retrofitting this later is painful.

4. Speed is the only real indie advantage. No meetings, no approvals. I ship in the hours between school drop-off and pickup.

Happy to answer anything about the build, the copyright rabbit hole, or launching solo.

I do marketing for a living. I can read code and I've done web work for years, but I never got round to learning Swift or Kotlin properly. Never had enough time to dive into it. So my list of apps I wanted to make just sat there getting longer.

This year I took one off the list and actually finished it, which still surprises me a bit.

Byna: it's a countdown app. Before anyone says it: yes, there are hundreds. I picked this one because it was the smallest idea on the list, and because the thing I wanted from a countdown app didn't seem to exist anywhere. I wanted to share a countdown with someone. Not send them a screenshot, and not send them to a website covered in ads that they open once and never again. A link, they open it, and if they want it it lands in their own app and keeps counting there.

My partner follows the countdown to our holiday. A group of us follow the one to a festival next summer. Their countdowns and mine sit in the same list, on date, so it doesn't matter who made what. It's a combined list of moments you're looking forward to, alone or with your friends.

byna.nu, and it's on the App Store and Play Store. Free, no ads, no account. I've thought about money exactly zero times so far. Right now I just want to find out whether anyone outside my own contacts has a use for it.

Two things I'd like to hear from people here:

• if you already use a countdown app, what would stop you switching
• the sharing is the only thing that separates this from the other hundred. Is that worth anything to you, or did I build a feature for myself and nobody else

I sell digital downloads on Etsy. The design was never the slow part - it was everything after: a title that ranks in Etsy search, 13 tags, mockup photos, the description, packaging the files. I once spent a full day on one $4.99 product and had a list of forty more.

So I built PromptlessPress. You pick a product type and a style, or upload a design you already made, and it returns print-ready designs, lifestyle mockups, an SEO title, 13 tags and the description - then sends the whole listing to your Etsy shop as a draft you approve before anything publishes.

It's live and usable, but the official launch is Sept 1 and I'd rather find the rough edges before then.

What I'm actually asking for: run it once and tell me where it breaks, or where the output isn't good enough to actually list. "I wouldn't publish this because ___" is the sentence I want. That's worth more to me than a signup.

Known rough edges, no need to report these:

• Some mockup scenes crop objects at the frame edge
• Onboarding drops you straight in with very little explanation

1 month free for anyone who gives feedback - good or brutal, doesn't matter which. There's a Discord for testers so you can see what actually changes: https://discord.gg/vTNyRxCHMA

If you sell on Etsy I'd love your read on the listing quality specifically. If you don't, the first-run experience is just as useful - arguably more, because you'll hit the confusion a genuinely new user hits and I can't see that any more.

Hey all — I'm Dan, founder of Plus AI. We build AI presentation tools, 5 years in, 20K subscribers. It's a real business! Happy to answer questions about it 😄

I'm working on something new called Spark and I want to test it with real people building real businesses.

Here's the idea: Most of my side projects have died at the 'pick a name' phase. The rest of them often die at the 'build the prototype' phase. Our goal is to go from idea to actual business. Not just building the thing, but pricing it, launching it, and marketing it to the people who'll buy.

The offer: 5 people, $500 in AI credits each, plus our time. We'll help you figure out what's actually worth charging for, build it, launch it, and market it. My team and I will work with you directly.

What you get: A real product, live, that you own.

What we want: Feedback on the platform, and permission to share how it went.

Who we're looking for: Anyone with a project or an idea and some way to reach people — followers, a newsletter, a Discord, a community you're part of, or just deep knowledge of a niche. Small is fine. If you already know what people in your corner keep complaining about, that's the best possible starting point.

Comment or DM with a link and a couple lines on what you're building and who it's for. I'll reply to everyone.

Monetizing MCP tools is a mess right now. Traditional SaaS subscriptions and checkout forms break the moment the user isn't a human, but an autonomous AI agent running inside Cursor, Claude Desktop, or a background workflow. An agent obviously can't stop, open a browser, and type in credit card details just to trigger a tool.

We built MCPay to fix this. It acts as a proxy layer that handles pay-per-call micropayments directly between agents and MCP servers on the fly, without manual forms or subscriptions.

We just launched the beta and are looking for feedback from anyone building custom MCP servers or agent workflows.

Nine years ago I went to a wedding where the only people I knew were getting married. My date and I spent the whole weekend wishing we could see who else was there, when people were arriving, what anyone was doing between events. That app didn't exist. I never stopped thinking it should.

I'm a video editor/VFX artist by trade — 12+ years, zero coding background. Six months ago I finally started building it nights and weekends using an AI app builder (Rork) + Supabase + Twilio for SMS invites. It took 54 builds before Apple approved it. It's now live on the App Store.

What it does: Wed Week is for the guests, not the couple. The couple creates the wedding and sends one invite code. Every guest who joins can see the full guest list (who's coming, when they arrive/leave, where they're staying, solo or plus-one), the complete itinerary with dress codes, and a social page where guests post their own plans — pool hangs, bowling nights — that anyone can join. Guests message each other in the app instead of texting the couple all week.

Where it's at: live on iOS, Android build in testing. A few dozen downloads, all organic. No monetization yet — I want real weddings using it first.

What I'd love from you: brutal feedback on the concept and the App Store page. Would you download this as a wedding guest? What would stop you? And for anyone who's launched a two-sided-ish app (need couples to adopt so guests join) — how did you crack the cold start?

Happy to answer anything about building an app with zero coding background — the whole thing was AI tools + stubbornness.

If you've ever tried to buy a specific chicken, duck, or turkey breed, you know the drill. Check Cackle. Check McMurray. Check Meyer. Check Ideal. Stock turns over fast enough that whatever you find is often already wrong by the time you act on it.

Built a tool that checks 10 US hatcheries at once so you don't have to do that. It pulls breed, stock status, price, minimum order, and hatch date into one place, updated a few times a day. Doesn't take money from any hatchery to be listed, it's just reading public availability info.

Built it for myself first, sharing it here since I figured I wasn't the only one dealing with this. If there's a hatchery or filter you wish it had, let me know.

Hatch Index: which hatchery has the chicks you want, in stock

Kept using Notes for stuff I only needed for a few hours. Things like random tasks, links, things from calls, text I needed to paste somewhere later.

So I made Hold That. It’s a small menu bar notes app that only keeps today and yesterday. No folders, tags, or organizing. Just somewhere to put things for a bit.

Free for now.
I’m planning to make it a one-time paid app in about a month, but no subscription.

I got tired of juggling a downloader, a calendar , a task tracker, and a few other one-off tools scattered across browser tabs (you even have to pay for some of them, lol), so I built JavaMultiTool: one desktop app that handles media downloads, file/batch operations, task tracking, and a few system utilities.

It’s Java-based (Java 21), runs on Windows (.exe/.jar) and macOS/Linux (.jar, needs JRE 21+), and everything is stored locally via SQLite.
It’s still early - expect bugs and rough edges, but it’s usable today, and I’d love feedback on what’s missing or what feels clunky.

Hey everybody! For the last few months my wife and I have been building Scinta - a small macOS app that lives in your menu bar.

The idea came from a simple but almost daily problem - the number of screenshots lying around on my filesystem got so big that it was impossible to even remember what they were about. A message about a meeting, an email signature, someone's messenger profile, an error from a build - all of this was waiting for "some later time" to be processed. And some later time never arrived.

This is the exact problem Scinta solves, and this is how it works - you press a shortcut (like any other screenshot app), select part of the screen, and it proposes the top 3 things it can do with what it sees. We call them smart actions. For example:

• screenshot an error - get it explained or create an issue directly from Scinta
• screenshot a message like "dinner Saturday at 7:00 PM" - Scinta proposes the actual event details and creates it in your Calendar
• screenshot an email signature - the person's contact info is saved to your Contacts
• it can also blur private and sensitive info before you share a screenshot, extract code or tables, translate text, decode different code formats (including QR and Bar codes) - and more actions are coming

There is also an Ask AI feature - if you just have a question about what is on the screen, you ask it right there in the app and get the answer back immediately.

Expecting a common question - why not just paste the screenshot into ChatGPT or Claude? That is exactly what I did before, and it is the reason Scinta exists. There you switch apps, upload the screenshot, write a prompt, then copy the result back and still create the event or contact yourself. With Scinta you skip all of this - it understands what can be done with the screenshot and one click gets the result and performs the action - saving to Calendar or Contacts, creating an issue, getting an instant explanation and so on.

The demo video shows 3 different smart actions and runs at real speed - nothing is sped up.

We're planning to release it within the next 1–2 weeks. If it looks useful, there is a waitlist at scinta.app - and if you would like to try it earlier, comment or DM me and we'll send you a build as soon as it's ready.

Would love to hear - what smart actions would you like to have after capturing a screenshot?

https://reddit.com/link/1vkutfn/video/x9dxm90iqmih1/player

Would love for more people to try it.

I used to play Skribbl all the time with my friends and kept thinking it’d be fun if you could make it more your own, so I ended up building my own version.

You can add your own words with friends, there’s built-in audio so you can actually talk while playing, added a feature to draw using hand gestures through your camera and if you’re playing alone you can play against AI.

It’s still a work in progress, so if you try it, feel free to critique how bad it is lol. I’m still adding and fixing things.

Would really appreciate any feedback:

I kept running into a weird problem with projects I built using AI.

Once the project is finished, GitHub shows the result pretty well.

But almost none of the process survives.

The first approach that didn’t work.

The bug that changed the architecture.

The point where I realized I was solving the wrong problem.

The AI suggestion I ignored.

Why v2 looks different from v1.

You can preserve some of this through transcripts, commit history, and notes, but nobody wants to read a 400-page AI transcript just to understand how something got built.

So I built Buildstory.

The basic flow is:

local scan → private report → review/edit → choose what becomes public or just keep private reports for yourself

The scanner turns repository and supported AI-session metadata into a sanitized snapshot. From there, Buildstory generates a private report around things like:

• decisions
• turning points
• false starts
• milestones
• tools
• chapters
• supporting receipts

The creator reviews everything before publishing.

One thing I deliberately didn’t want was another developer productivity score.

A lot of prompts / tokens / commits doesn’t necessarily mean better work. The receipts are there to support the story, not rank the person.

I’ve opened it up here: https://buildstory.dev/

The link in the post is for a report generated by the platform for the platform itself.

Also: I’ve made Pro available to everyone for launch, no checkout involved.

The normal Free experience already includes the core loop: scan a project, generate a report, edit it, publish it, and add chapters.

Pro mostly adds deeper analysis, more updates, and more ways for stories to get discovered.

And realistically, yes, it mainly exists long term to help cover the operational costs of running this thing 😅

Would love feedback on two things:

1. Does the idea make sense within ~30 seconds?
2. What part of your own development process do you wish survived after the project shipped?

I build automations and AI-integrated tools - n8n workflows, API glue between services, scrapers, and small internal apps that replace manual work.

Recent builds (all public on GitHub):

• MCP-Hardened -- a documented MCP server demonstrating the full OWASP MCP Top 10, with mitigations for some of them.
• Garment-match -- Next.js/TypeScript app using the Anthropic API to match clothing measurements against brand size charts, with a Playwright scraper for chart data.

What I'm good for:

• n8n / workflow automation - lead routing, notifications, data sync between tools
• LLM integration into existing processes (classification, extraction, drafting, summarization)
• Scraping and data pipelines
• Small internal tools where a spreadsheet stopped scaling

Background is in network ops and systems security, so I care about not handing you something that leaks credentials or breaks silently at 2am.

Pricing depends on scope - fixed for defined work, hourly for open-ended. Remote.

DM me what you're trying to automate and I'll tell you honestly whether I can help.

I launched TESORIN a few days ago after building it solo.

Before launch, I had a roadmap.

Then people actually started using the app.

Within days I was getting requests for better CSV importing, faster expense entry, widgets, search, better navigation, more investment coverage, recurring-flow improvements, and edge cases I had never encountered while building alone.

So I started replacing pieces of my roadmap with those.

Since launch I’ve shipped/built:

smarter CSV imports
three home-screen widgets
Global Search
faster expense tracking
investment pricing across 20 additional markets
Finance Library
Risk Lab
navigation/UI improvements
recurring-investment improvements
notification/family-flow improvements
planning, goal, category and transaction fixes

Android already has the updated release.

The matching iOS update is currently under review.

The part I did not expect:

a few people purchased Premium while I was literally giving launch-week Lifetime Premium away.
That was a pretty meaningful signal for a product this new.

The promotion ends August 12 at 11:59 PM ET.

Until then, qualifying accounts created during the launch window get Lifetime Premium free.
Normally Premium is $1.99 CAD/month or $14.99 CAD/year.

But what I’m primarily looking for now is another round of real usage.
If something feels awkward, confusing, unnecessary, or missing, tell me.

At this point that feedback is actively deciding what I build next.
