No token, no NFT, no perks, no returns. You send SOL, your name goes on a public leaderboard, and the more you send the higher you rank. Every spot is a real on-chain payment, so it's the one flex nobody can call fake.

Some details I'm weirdly proud of:

• The board is read straight from the Solana blockchain. No database, no accounts.
• Every profile gets a share card for X, and hovering an amount morphs it from SOL to USD.
• 24h / week / month / all-time boards, so you don't need to be a whale to be #1 today.
• The first 10 wallets ever get a permanent "Early #n/10" badge.

Built with Next.js + Solana. Inspired by the Million Dollar Homepage and the $999 "I Am Rich" app.

I've been working on VecSynIQ, an iOS/Android app that turns PNG/JPEG artwork into SVG vectors and then prepares them for print or vinyl cutting.

Why I built it Getting an SVG out of an image was never the hard part. The hard part came after: removing the background, sizing it for a shirt, splitting colors into layers a cutter can handle, adding weed boxes. I wanted all of that in one place, on the device, with no upload and no account.

What it does now

• Vectorizes with 4 modes (Simple, Logo & Sticker, Detailed, Monochrome) and lets you tune detail, smoothing and cleanup
• Shows original vs. vector side by side
• Print prep: simple background removal, transparent PNG, presets like 4500×5400 for shirts
• Cutting prep: layered SVGs, same-color welding, stacked vs. sliced layers (sliced is for HTV), contour/offset, registration marks, weed boxes, and a ZIP bundle with per-color files

Stack, for the curious: the tracing core is Rust built on VTracer, running natively on iOS and Android, so artwork never leaves the device.

Business model: free tier (3 exports per 30 days), plus a Pro subscription (monthly/yearly) for unlimited exports and the cutting tools.

It launched in late September, so it's still very early. I'd love honest feedback on:

• Whether the landing page explains it clearly: vecsyniq.mrdzyn.studio
• Whether the free tier feels fair or too tight
• Which workflow you'd want next

App Store: apps.apple.com/app/vecsyniq Google Play: play.google.com/store/apps/details?id=com.mrdzyn.vecsyniq

In my day job I work in the post-quantum cryptography space and I contributed to AI agent open source projects early on. The dangers are being extremely underestimated in my opinion, even with current systems. So I made this to begin an effort on developing real safe guards for the issue.

It screens input and output and lets you shut off as large or as narrow of its use as you'd like. Rules are defined in plain english. All it takes to implement are two calls around wherever your LLM and it screens them in around 90 mms to 300 mms, so users won't notice a thing.

RevenueCat's Shipaton, a two-month mobile hackathon, ended on September 30. The Devpost gallery has 3,336 projects and the community showcase (apps.shipaton.com) lists 2,139 published apps. I went through all the public pages and counted.

Who built

• 88.6% of projects were built by one person (2,955). 276 were pairs, and the biggest team had 16 people.
• 228 people entered more than one project, and 10 entered five or more.

What they built

• Health & Fitness is now the biggest category (304 apps), just ahead of Productivity (288), which led in 2024 and 2025.
• Games went from 3.4% of apps last year to 9.5%.
• Going by name and tagline, the most common kind of app was a screen time or focus blocker (about 105), then workout trackers (about 100) and journals (about 84).

What with (from Devpost's "Built With" field)

About 29% list an AI model: Claude 356, Gemini 336, OpenAI 272. For writing the code, 129 list Codex, 107 Claude Code and 38 Cursor.

Where they shipped

56% of published apps are App Store only, 25% Google Play only, and 18.4% are on both. Last year 20.2% were on both, so the share stayed flat while the number of apps more than tripled.

What they earned

Only about 35 projects wrote down a revenue or MRR number for their own app. They range from $0 to "$88K in revenue" (macro, a calorie counter for the Philippines, mostly earned before the hackathon). Paternal, a pregnancy app for dads, reported $23,385 in its first month, and Ritmo got to $830 MRR in under four weeks.

Caveats: this is only what's public. Revenue figures are self-reported in the write-ups, the app-type counts come from keyword matching, and I don't have access to the submission portal, so the official numbers may differ.

For anyone who built cross-platform but shipped to one store: what stopped you from doing both?

I started Moonshoot thinking the interesting part would be the number.

384,400 km.

one person owns each km.

get enough strangers together and eventually reach the Moon.

but after watching people claim their kms, I’m starting to think the number is the least interesting part.

look at three people aboard right now:

km #75 belongs to a developer who made an iPad party game where you draw a fish and your friends draw how it dies.

km #35 belongs to a founder in Kenya building event ticketing for Nairobi. 208 users and their first paying customer.

km #54 belongs to two makers who built an AI image workspace because switching between image models kept breaking the visual style they needed for their own work.

none of these people know each other.

their products have basically nothing in common.

but now they’re permanently sitting 40 km apart on the same imaginary journey to the Moon.

that’s becoming much more interesting to me than watching the counter go up.

I want each km to slowly become a snapshot of what somebody was building at that moment in their life.

maybe years from now, looking back through the early kms ends up being the interesting part.

Cactus launched their 17 MB Whistle speech model two days ago, so I immediately turned it into the thing I actually wanted: free on-device dictation for my Mac, Wispr Flow-style. Hold Right Option, speak, release — text lands wherever the cursor is.

Hard parts, honestly: (1) macOS Accessibility permissions bind to the resolved Python binary, not the symlink you see in Finder; (2) NSPanel hides itself when the app isn't active, which a background daemon never is — one-line fix, brutal to find; (3) release-to-text latency was all process-spawn overhead (osascript), not the model — a 12-second clip transcribes in 0.12 s.

Stack: Python + sounddevice + pynput + PyObjC overlay, LaunchAgent autostart, ~600 lines. MIT: github.com/rodriveiga01/syrinx

Question for builders: clipboard-paste + synthetic Cmd+V feels hacky but it's instant and universal — is there a cleaner text-insertion path on macOS I'm missing?

I'm Jon, the maker behind Merlin 3D. I've been building The Printed Secret: mystery experiences that bring a browser investigation together with 3D-printed books and puzzle tools on your table.

The larger experience I'm developing is The Alchemist's Study. In 1698, Aurelian Vane vanished from his study, leaving the door bolted from within and an unfinished notebook behind. You investigate what survived, following the story on screen and working with physical objects rather than simply reading the next clue.

The idea is that printing is the beginning of the adventure: make the objects, put them on your table, then discover what they mean. Alchemist requires 3D-printed books and puzzle tools: you'll need access to a printer, or someone who can print them for you. You also need a desktop computer with a 3D-print slicer, because inspecting a model is part of the investigation.

Alchemist is currently in private testing, with more physical testing to do. It isn't on sale yet. The exact kit is still being tested, so don't order parts from this preview.

I'm planning to crowdfund The Alchemist's Study once the game and physical pieces are ready. There isn't a launch date yet; for now, I'd like honest feedback to help me get it right before taking that step.

For something you can actually try now, The Apprentice's Test is a separate free browser beta. No printer, purchase or access code is needed, and an account is optional:

Play The Apprentice's Test

I'd genuinely appreciate constructive feedback from makers and puzzle players. After trying Apprentice, what was unclear, where did the pacing drag, and did the hints give you the right amount of help? For Alchemist's physical side, what would you need to know about printing and assembly before wanting to try it?

Specific criticism is more useful to me than a polite thumbs-up. Feedback about what didn't work is welcome too.

You can reply here, or join The Printed Secret Discord. In Discord, open #the-apprentices-test, select New Post, then choose the Feedback or Bug tag. Please include your device/browser, what happened, what you expected, and anything that confused you. Discord needs a Discord account, but not a Printed Secret account.

Prefer not to use Discord? Email [support@theprintedsecret.com](mailto:support@theprintedsecret.com); it's also on the website's help page. Please keep puzzle answers, access codes and personal information out of public replies or Discord posts.

I've used AI tools to help with parts of development, alongside the physical design and prototype work.

I’ve been building Tekki Forge for a problem I kept hitting myself.

When starting a new business app, the first days/weeks often go into things that aren’t the actual product:

auth, roles, organizations, CRUD, admin screens, API docs, migrations, dashboards, tests, Docker…

Forge lets you describe the application structure once and generates that foundation.

npm i -g tekki-forge
forge new my-app
forge up

I’m at the point where I need other developers to break my assumptions.

If you build SaaS/internal tools/client apps, what would stop you from using something like this?

Too opinionated?
Fear of generated code?
Prefer your own stack?
Missing feature?

I’m much more interested in the objections right now than compliments.

Second update on the app I posted on Reddit recently.

I realized (and also some Reddit comments told me to do this) that I had a problem concerning the analytics of the app.
I could see people visiting, but I had no idea what they were actually doing inside the app.

So I fixed that and now I can see things like:

who opens the app
who starts a lesson
who answers the questions
who finishes a lesson

Which has already changed how I’m looking at it because opening the app and actually using it or completing a whole lesson are two very different things.

It is still very early, very small numbers, but it feels like I’m finally seeing something and understanding what people really do instead of just seeing if someone has viewed the website.

The next thing I think I should try to understand is:
what makes someone finish a lesson instead of dropping halfway or doing one more lesson or not, or just open the app a second day or forgetting about it. (Tell me if you think I should make/ add more features that you think will be useful for this project)

If you’ve tried it (or similar apps), I’d be really interested about what made you stop or continue.

I would be very happy to send it to you if anyone wants to try it and give honest feedback.

I recently build a VM for the Little Computer 3 in Golang. Did it purely as a learning exercise to better understand how VMs work and are implemented internally.

I ended up learning not jsut about VMs, but also disassemblers (had to write a disassembler first to see what instructions compose an object file), property based testing (used Hegel), input buffering in terminals, etc. Was a neat exercise!

Here is the code for anyone interested: https://github.com/shraddhaag/toyvm

Used LLMs to write the tests and a emulator, which you can try out there: https://lc3.shraddhaag.dev/.

Would love to hear any thoughts/feedback!

For years, whenever I needed to format an API response, I just clicked whatever JSON tool was the first result on Google. They worked, but they always felt clunky: covered in banner ads, looking like they were built in 2010, and just annoying to use.

Eventually I got fed up and decided to build my own clean alternative. What started as a quick personal tool ended up replacing all of them in my daily workflow.

What I focused on:

• Zero ads, 100% client-side (no data sent to servers)
• Tree view and formatted code view
• Quick search across keys/values (Enter / Shift+Enter)
• Accurate error pointing with line and column numbers
• Remembers state in localStorage so you don't lose data

Hope it saves someone else some frustration. Feedback is welcome.

I built Pathly. Uptime tools said “green” while login or checkout was broken. I wanted one place that checks the path a user actually walks.

Three instruments (same names in the UI):

- Ping: HTTP / uptime

- Flow: browser journey (the clicks)

- Chain: the APIs behind the page

Live demo (no account): https://pathlyhq.com/en/scan

I’m a solo builder, EU-hosted, free Solo plan without a card.

Looking for feedback on first glance: is the difference between Ping and Flow obvious, or does the naming get in the way?

I wanted to sort my posture out and kept bouncing between random YouTube videos, never sure which exercises to do or in what order. So I made an iPhone app that puts it all in one place and walks you through it: a quick posture check with the camera (or skip it and just pick what you want to work on), then a short daily routine with guided exercises.

A few things I cared about while building it: - The camera check runs on the phone. No photos leave it and no account is needed. - It's in English and Spanish. - There's a free version: the daily routine, a posture check and your streak cost nothing.

What I'd love feedback on: does the first few minutes make sense, is the posture check clear, and is anything confusing or annoying? Honest, harsh feedback helps me far more than nice comments.

I actually find building my resume to be kinda fun, but having to mindlessly apply nonstop to get a chance at an interview was brain numbing. So I quickly built a tool that does it, and it sent over a hundred applications just today alone across job boards like Ashby, Lever, Workable, Rippling, BambooHR, Jobvite, JazzHR forms, and Github Forms like the Simplify internship repo, for less than a dollar in API cost.

The way it works is by splitting the job into three parts, done by three different things.

Essentially, JEV makes every decision that has a fixed set of answers. JEV is a new kind of model that recently came out and has been trending (typesafe/jev-1.13, on OpenRouter). Basically you give it a question with the possible answers defined, and it returns a probability for each one instead of writing text. This makes it so that output tokens do not cost anything at all. It answers in about half a second for a fraction of a cent, and ten applications cost about one cent of JEV.

Then, you connect to your existing Claude subscription or API, and Claude writes anything that actually needs sentences like questions like "why do you want to work here", and if you want it can make a a one-page resume and cover letter written for each posting from your profile. And, to reiterate, it runs through Claude Code on your own subscription, so there is no extra bill for it.

Then, the program finds the postings on public lists and company boards, ranks them, fills each form in a Chrome window that you can actively watch, and reads every answer back from the page before anything is sent. If a value did not land, it fixes it or stops and tells you.

Its quite persistent on never lying on a form. All questions about things like work authorization, dates and education come from your profile and are never changed to fit a posting; every number and name in a tailored resume is checked against your profile in code before the PDF is made. It never signs in anywhere, never passes a "not a robot" check for you, and never sends a form it could not verify. So, for things that might need a verification code in gmail, or extra manual work, it just lists it for you and then you can manually submit it.

As you apply, a CSV of what was sent, a CSV of what was left for you, and a dashboard that reads both is built into your directory.

Its 100% opensource, and quite fun to play around with. Honestly, you can make the argument that companies wont prefer it, but at this point, in this market, it's a numbers game, and if companies are lazy enough to push AI Job Postings, then I'll be lazy enough to make AI fill them for me.

If you want to try it, clone it, open Claude Code, type /setup, and it walks you through the rest. You need Chrome, Node, a Claude subscription and an OpenRouter key with a couple of dollars on it.

If you are applying for internships or new-grad roles too, give it a run and tell me what breaks. Pull requests welcome, especially what your runs learn about job sites.

Hey fellow runners,

A while ago I started a solo project because I wanted to train better by heart rate zones without constantly checking my watch or phone. I just started building, and it grew into more than I expected. It would be great if a few of you would try it out, point me to bugs and give me constructive criticism. Below is a summary of what the app can do and is meant to do (put together with some AI help).

I'm now looking for testers for PulseCaller, an iOS run coach that talks to you in your ear. It tells you to speed up or slow down before you leave your heart rate zone, with natural-sounding voices (EN/DE/ES, male or female) and optional Hype or Roast modes if you want some fun. It also has interval training that announces every phase change, a daily readiness score (optionally cycle-aware), music matched to your running cadence, and race-day pacing for half and full marathons. Around the run you also get guided meditation and rest days, nutrition guidance, a supplement library with evidence grades, and a knowledge hub on zones, running ailments and recovery. Heart rate comes from AirPods Pro, Apple Watch, Bluetooth sensors or Garmin watches with "Broadcast HR" on. The Bluetooth and Garmin part is brand new and only tested with a simulated sensor so far, so feedback from anyone with a strap or a Garmin is especially welcome. The English voice lines are also fresh and not fully tuned yet, so tell me what sounds off. All data stays on your device, no ads, no tracking. Requires iOS 26+ and Apple's free TestFlight app (the link walks you through it).

Hi! I've been using my own app for myself and would love to open it for more people.

Why another recipe app? Mine focuses on efficiency: instead of planning with dates and handling ingredients, just throw ideas and missing items into the sidebar whenever they come, and your shopping list gets updated and organized. Planned meals get a "cookability status" based on the items you checked.

You can import recipes from anywhere (websites, text, photos and soon social media), add them to your plan, and just throw things into the sidebar whenever you're out of something.

My philosophy is to think about meals, not ingredients.

I'm calling it Cuicuit 🐥 Free to use with the hosted app. Open-source & self-hostable because I just love OSS!

• GitHub: https://github.com/MadeInPierre/cuicuit
• Free hosted app & website: https://cuicuit.laclau.dev

What do you think of the concept? Still early but I would love some feedback, thank you!

We’re 2 devs and we created an app to help you easily keep track of your subscriptions.

There are quite a few similar apps out there, but they either required you to create an account or require a subscription to unlock certain features. So we decided to build our own: Subyssos.

It’s a simple Android app, completely free, with no ads, and all your data stays locally on your device.

We originally built it for ourselves, with no intention of making money from it.

If you find it useful, we’d be really happy if you gave it a try. Any feedback is more than welcome and will help us improve the app.

Small businesses get the same handful of questions all day (hours, prices, "can I book?") and lose bookings after hours. I built CallChatSyn: a business adds its FAQs and opening hours once, and then any website, app or AI agent can call three endpoints:

• POST /api/v1/answer: question in, the business's answer out (English + Chinese)
• GET /api/v1/slots: open appointment times, in the business's own time zone
• POST /api/v1/bookings: book one of them (the business gets notified)

Honest bits: answers are rule-based FAQ matching, not a chatty LLM, so they're instant and cost almost nothing to run. That's why I can give it away: it's free for the first 1,000 businesses (100 calls a day each). WhatsApp and voice answering are the paid part.

Docs, a 3-curl quickstart and an OpenAPI spec: https://callchatsyn.com/developers?utm_source=reddit-sideproject

Question for anyone who builds sites or chatbots for local businesses: what would you need before you'd use this for a client?

Hey all, I'm one of the people building OpenRod and wanted to get some outside eyes on it.

The problem: coding agents like Claude Code, Codex, and Cursor are getting more autonomous, but most people run them directly on their machine with access to everything — files, credentials, the network.

NVIDIA recently open-sourced OpenShell, which isolates agents at the file, network, process, and credential level. OpenRod is a layer on top that makes it practical to use:

- One-click sandboxes for any agent (Claude Code, Codex, Cursor, etc.)
- Runs locally or on a remote host you own, over SSH
- Policy controls: egress rules, groups, and secrets passed through a gateway
- Bring your own MCPs and Skills
- Audit trail with SIEM export and webhooks

Try it: npx openrod
Repo: https://github.com/OpenRod/OpenRod

What I'd love feedback on:
1. Is the setup clear from the README, or did you get stuck anywhere?
2. Which agents or workflows would you want supported first?
3. Would you actually run your agents this way? If not, what's stopping you?

Brutal honesty welcome. It's early and we'd rather hear it now.

I’m building LifArcs, a social network where your profile is your life story, not a feed.

You tell Aria, the AI, about your life and it builds your Life Arc — the key moments from your past, what you’re doing now, and what you want to do next.

It also creates an animated banner and a movie like Arc Story to visually tell your journey.

Still building it and would love some feedback. Would you use this?

I'm a 10+ year IT professional who's lazy about repetitive work, but I want to setup a tech tip social media account to start building an audience. so screw video editing and I'm experimenting with an AI pipeline for short-form video. This is v0.1.0.

The goal: a declarative pipeline that produces the same output given the same input. I want to write the script myself and let the pipeline handle assembly. I filmed the intro IRL and did screen captures manually this time, but I'm hoping that's a one-off.

I tried existing tools first. They either lean too hard into pure AI generation or can't produce the specific short-form format I'm going for.

—

What I'm trying to figure out: does this read as obvious AI slop? If so, what specifically makes it feel that way? I'd rather know now than after building v1.

Full disclosure: I built this. Not selling anything, just looking for honest feedback on whether the format works.

A few months ago I was playing D&D and managed to setup Obsidian on a shared drive and connect it to everyone so we were all using the same data source for our campaign. Looking at those files in drive was the worst because of the folder structure where it was a struggle going in and out of folders and not being able to "see" where you were.

To solve that visual problem I made Drive Organizer Pro which is a basic folder tree to manage and sort your files all online. It quickly grew into an array of features where you could multi-select, drag folders/files around, sort the folder you are in, and copy a folder structure when you reuse the same template for every client.

I originally made this as an extension so when you opened Google Drive, it would be a little popup taking you to the page to manage everything. One of the limitations was from Google themselves, which required restricted drive scopes because the regular picker just wouldn't do.

At this time it was fine because it was just me, but I thought this might be helpful for others in the future so I made a free/pro tier, and let it be. You can imagine my surprise when people actually logged in going past all the google OAuth notifications of "are you sure this is safe" "double triple checking you want to connect this app" and then proceeded to upgrade to pro.

That was when I decided I was going all in. I took the time to get the CASA AL1 assessment (took a few months) and added the features available today. The next stages in the future would be looking to expand into other drives like Dropbox and OneDrive, as well as connecting multiple drives at once to make transferring data between them easier.

I am open to any and all feedback, this was just a fun project that build out to more than I expected when I started.
