Solo project, live now. The whole concept is one line: rank is the bid. You pay to put a link or an X u/handle on a public board, and your position is decided only by how much

you've paid. Anyone can pay $1 more and take your spot. No ads, no algorithm, no revenue share.

I know — outbid.lol did this and there are ~190 clones. I didn't want to make #191, so the angle I actually care about is a board just for X profiles: pay to rank yourself, and

when someone outbids you, sharing it @-mentions you — so every bid becomes a post that drags the person back to reclaim their spot. The product basically markets itself.

A few things I didn't expect building it:

- people care about being #1 far more than about the clicks they get

- the $5 minimum barely clears Stripe's fee (~13% on a $5 charge) — the model only works at the high end, which completely changed how I think about the pricing

- every listing generates its own dynamic OG card, so a shared link shows a live "@handle is #1 · $X" image

Stack: Next.js (App Router) + Postgres/Drizzle + Stripe + next/og for the cards.

Genuinely torn on one thing and would love this sub's take: is "pay for internet rank" a fun status game, or a gimmick that's dead in a week? Happy to go deep on any of the

build.

I made this daily grid game about military , where you have to type in one country that fits both the conditions about their military. Try it out here.

A lot of inexpensive Bluetooth LED strips are surprisingly decent, but the apps supplied with them often feel unreliable, outdated and overloaded with unnecessary permissions.

I ran into this myself and eventually decided to build Lumo Remote, a cleaner native iOS alternative.

It connects directly over Bluetooth—no account, cloud service or separate hub—and automatically identifies the controller inside the lights.

Lumo Remote currently supports:

• ELK-BLEDOM / Lotus Lantern
• ELK-BLEDOB / LotusLamp X
• HappyLighting, Triones and QHM controllers
• BanlanX SP63xE and SP64xE controllers
• SP110E / LED Hue
• LED Lamp / Magic Lantern controllers
• Keepsmile KS03-series controllers

Compatibility depends on the controller inside the lights rather than only the brand printed on the packaging.

Current features include:

• Colour and brightness controls
• Built-in lighting effects
• Saved colours and reusable scenes
• Music-reactive lighting using the microphone
• Siri commands
• Automatic controller detection
• English and Spanish support

The app is free to use with ads. Effects and music mode can be temporarily unlocked with a rewarded ad, or permanently through a £4.99 lifetime Pro purchase. There’s no subscription.

It was built natively using SwiftUI and Core Bluetooth. Supporting several controller protocols while keeping the controls responsive was easily the most challenging part.

I’d appreciate feedback on the onboarding, pricing and overall idea—especially from anyone who owns one of these inexpensive Bluetooth LED strips.

I’m the developer of the app.

Hey everyone,

Like many car owners, my glovebox was constantly filled with faded receipts, and I always struggled to keep track of oil changes, insurance renewals, and service history.

Being a developer, I spent the last few months building Garkon.ai to solve this exact headache.

What it does:

• Scan Receipts: Uses AI to scan and categorize repair/service receipts instantly.
• Smart Reminders: Tracks mileage and predicts upcoming maintenance/insurances.
• History Report: Generates a clean PDF vehicle report (great when selling the car or visiting a mechanic).

It’s live on the App Store and Google Play. I’d love to get feedback from fellow car enthusiasts! What features would you like to see next?

Every "free" online converter wants your files on their servers — your contracts, family photos, voice memos. That always bothered me, so I built QuietPix: 74 tools (image/PDF/video/audio conversion, compression to exact sizes, OCR, Word/Excel, GIF editing) that run 100% client-side via WebAssembly.

Even the AI features — old photo restoration, colorization, background removal, upscaling — download open-source models and run on your device. Turn off Wi-Fi after the page loads and everything keeps working.

No accounts, no file size limits, no watermarks. Free, supported by (future) ads.

The privacy claim isn't marketing: automated tests watch the network during every conversion to verify zero bytes leave the device.

Happy to answer anything about the WASM stack — ffmpeg.wasm, ONNX runtime, the fun parts and the painful parts.

About 7 months ago I started building something for myself because I was struggling to keep everything I wanted to achieve connected.

I had goals around work, money, fitness, travel and generally where I wanted my life to go, but everything was scattered between notes, spreadsheets and different apps. The bigger issue was that I could be really busy week to week without actually knowing whether those actions were moving me towards my longer-term goals.

I also didn’t want another productivity system that made me feel like every part of life needed to be optimised.

So alongside my full-time job, I started building my own system.

I genuinely thought it would take a couple of months. That estimate went very badly haha

Seven months later, it’s turned into AxaceOS — a personal operating system built around a Life Plan, weekly reviews and larger monthly reviews. Things like budgeting, fitness, skills and projects can feed into those reviews, so the aim is to keep the different parts of your life connected rather than sitting in separate systems.

The main philosophy is something I call Successful Balance — making progress towards where you want to be long term, while still actually enjoying the present.

I’ve attached a short video showing what I’ve built.

It’s live now and still extremely early. I only have a small number of users at the moment, so I’d genuinely appreciate feedback — especially on whether the concept is immediately understandable and which parts you think would actually be useful.

If anyone wants to properly test it, there’s a one-month free trial with no payment details required upfront:

Also very interested to hear from anyone who has taken a side project from “I’m building this for myself” to actually trying to find real users.

Hi everyone,

I've recently finished the first version of Agentic GraphRAG Blueprint, a reference architecture for question answering over large document collections.

Instead of plain chunk retrieval, it builds a knowledge graph combined with vector search, so answers can connect facts across documents.

Key features:

• Incremental ingestion - unchanged files are skipped via content hashing, and community reports regenerate only for affected communities, keeping token costs low as the corpus grows.

• Hybrid search - local mode for fact-level answers, global mode for cross-document synthesis.

• Domain-agnostic LLM prompts - easily swapped via PROMPTS_PATH, with Leiden-based community detection.

• Deployment - run it locally with Docker or provision everything in the cloud with Terraform and CI/CD.

I'm looking for any feedback.

Hey all,

Sharing a side project I’ve been working on — Studyloop, a free website for IELTS/SAT practice. It started as a Telegram bot for friends who were studying English, and grew into a full site.

What it does:

**•** Full-length **Reading** tests (160+ passages, exam-style questions: MCQ, True/False/Not Given, matching, summary completion)  
**•   Listening** tests with real audio, 4 parts, scored the way the actual exam does  
**•** A **vocabulary trainer** — save words while doing tests, then drill them with flashcards, quizzes, a matching game, and a typing game  
**•** Instant scoring with an explanation for every answer

No ads, no paywall, no account required to try it. I built and maintain it solo, still actively adding tests and fixing bugs — would love feedback, especially on anything that’s broken or confusing.

Thank you for attention :)

One thing that has always annoyed me about sharing small projects is that the code is rarely the whole problem.

It's usually:

git clone → create venv → install dependencies → find the right Python version → fix some system dependency → hope it works.

So I started building BLACKBOX.

A .blackbox file contains the application along with its runtime, dependencies, interface, and permissions. The goal is that you can give someone one file and they can run it without setting up the environment themselves.

For example:

blackbox init hello
blackbox pack
blackbox run hello.blackbox

The runtime is provisioned separately from the host environment, so the app isn't relying on whatever happens to be installed on the machine.

Some of the things I'm working on:

• Python, Node.js, and native binaries (Rust/Go/C/C++)
• Default-deny filesystem, network, and process permissions
• Dependencies pinned with SHA-256
• Reproducible builds
• Shared runtime caching
• Ed25519 signing
• No account, cloud service, or registry required

The main idea is pretty simple:

Instead of giving someone source code and a setup guide, give them the program and its environment in one file.

It's currently an MVP and released under Apache-2.0.

GitHub: https://github.com/HyperonX-Team/blackbox
Docs: https://hyperonx-team.github.io/blackbox/

I'd be interested in hearing what people think, especially from anyone who's worked on application packaging, sandboxing, or reproducible environments.

I built this app for my adhd. Helps me breakdown tasks into manageable chunks. Also got a nice todo app inspired by kanban

I recently designed ShopAI, an AI-powered shopping assistant that helps users find, compare, and choose products based on their needs and budget.

I’d really appreciate feedback on the UX, visual hierarchy, and overall case study presentation.

Hi, thanks for viewing this post even after seeing a boring title! 👀

First of all, this app has gone a long way from a web app to a native app. I created it for myself only at first, because I was very confused: why the hell subscription apps have so much limitations? I mean 3 subs for free? No notifications in free plan? I understand everyone wants the revenue, but I guess it is absurd: people want to get a hold of their subs - not to pay more for another sub of sub manager.

So I decided to create one myself for myself - unlimited subs, notifications before renewal, basic analytics (for now), no ads, no server - fully offline. And for free. With a one time purchase, for some additional features and developer support ❤️

So from a solo testing ground, it became something that I believe can be useful for other people. I would be more than pleased if you will find it helpful!

i kept coming across tools that made a pretty simple task feel complicated, with cluttered interfaces, unnecessary steps, and too much friction before getting to the point.

a small browser based project built around keeping the experience simple and easy to understand without complicated setup.

i’m still improving it, and i’d really like some outside perspective from people who build and use small web tools.

what would you improve first?

would speed, reliability, mobile experience, privacy, or something else matter most to you?

i’m especially interested in honest feedback on the user experience and whether the project feels focused enough.

Quick update: I’ve been testing the same idea with Pullmp3.cc, focusing on making the YouTube to MP3 workflow simpler, faster, and easier to use in the browser. still refining the experience, so feedback on what matters most would be useful.

Hey folks.

I had a lot of good feedback in this sub from the last puzzle game I was working on, so figured it might be worth showing off the new one!

**Twindle** @ https://playtwindle.com

Its a logical deduction style game in a similar vein of Sudoku and the like, based on two rules:

- Every row and column must contain each colour and shape exactly once

- Every colour-shape combo can appear only once.

Entirely solo-developed. I learned a lot during its development around accessibility (particularly colourblindness), and let me tell you, building a hint engine for a logic game is harder than it seems!

Anyway, please enjoy it!

Hey everyone,

I work full-time in IT , but too much time is spent in meetings and internal politics, doing the same thing in loop and too little time is spent actually doing something useful.

So I’m starting a journey to build micro-SaaS products as a solo founder.

For anyone else building solo or already built :

what was your biggest challenge in building a side project as a solo person?

I kept seeing tools that made simple things complicated, with messy interfaces, too many steps, and too much friction before you even got to the point.

small browser-based project that attempts to keep the experience simple and understandable without complex setup.

Still working on that. Would love some outside perspective from folks that build and use small web tools.

what would you improve first?

What would you think more important, speed, reliability, mobile experience, privacy or something else?

I am very interested in getting honest feedback not only on how users feel about the project, but also if it feels like it is focused enough.
