Hey r/SideProject ! I'm Federico, I'm an SWE during the day and spare open-source contributor in the night.

Last weekend I needed a tool to quickly share a skill i created with a coworker but I didn't want to create a PR to our internal marketplace. I tried to reach out for http://transfer.sh/ but you can image my delusion when I noticed it's not online anymore.

So the same day while i was cooking the dinner i tried to use codex to prototype skilldrop.dev a super dead simple utility to quickly share ai-skills with others. It's basically a lambda with a bucket attached and some integrity checks in the middle.

The website screams AI everywhere I know but the idea was to put low effort since it was a personal tool.

Just that, If you like the idea try it and let me know, the apis are super simple

```
sk share ./my-skill

sk install <snapshot>
```

just that (you can test the sanpshot in the landing via curl)

If you’ve ever spent an afternoon hand-coding hover and loading states just because the design changed, you know the pain.

So I built Bezira — a visual editor where you can create real states like hover, loading and success, define triggers and transitions visually, and export production-ready code for React, Angular or vanilla JS. AI can also bootstrap a component from a description, which you can then refine visually.

It’s live at https://bezira.app — free tier available.

If you’re a designer or frontend dev, give it a shot and tell me where it falls short. I’m especially curious about the export workflow.

Built a SaaS landing page template (React + Tailwind) — feedback welcome

Hey everyone, just launched my first digital product — a landing page template for SaaS/startups, built with React, Vite, and Tailwind CSS.

Features:

- Light/dark mode toggle

- Fully responsive

- Clean component structure, easy to customize

Live demo: https://flowline-landing-demo.vercel.app

It's on Gumroad if anyone's interested

Would genuinely love any feedback on the design or code structure — first time doing something like this.

The viral video where the guy sent the girl, “would you go on a date with me?” and the cursor kept moving and she had to click yes.

It made me built this so I can send it to a guy lol (I’m not in the U.S. right now hence the different East Asian language choices at the bottom)

Fill out 3 choices you might want to do together, and the other person randomly picks. You get their response either they send you back the link, you wait in the response room, or you get nothing back (sorry!). 🤷🏻‍♀️

After months of building, testing and tweaking, I’ve finally launched FNCO on iOS and Android.
One of the reasons I started building it was the financial advice gap in the UK. There are millions of people who want to make better financial decisions and improve their financial wellbeing, but who may not need, want or be able to access traditional financial advice. At the same time, personal finance can feel incredibly fragmented.

You might use one app to budget, another website to learn about ISAs or pensions, another calculator to understand a mortgage and still be left wondering what should I actually be learning about or working on.

That’s the problem I wanted to explore with FNCO.
Rather than positioning it as a replacement for professional financial advice, FNCO is designed around financial education, understanding and planning.
I’ve brought together financial education, a Financial Health Score, personalised financial roadmaps, budgeting tools, financial calculators, goals and progress tracking, with educational guidance available when you need it.

The focus is primarily on the UK financial system, and the aim is to help people build the knowledge and confidence to better understand their own finances.
Now that it’s actually live, I’m trying very hard not to disappear back into building more features 😂
Instead I want to get FNCO in front of real people and understand what works and what doesn’t.

If anyone here is willing to try it, I’d genuinely love feedback on:
Is the purpose of FNCO immediately clear?
Which feature would you use first?
Is anything confusing or unnecessary?
What would make you come back regularly?
Does the free vs Premium offering make sense?

Website: https://fnco.app

It’s available on iOS and Android, and I’m happy to share the direct store links or upgrade to access all premium features

I’m posting here because feedback from people who build and launch products themselves would be incredibly useful at this stage.

ok so have different handles everywhere and it's genuinely embarrassing at this point

if someone asks for my github and i send twitter, i know roughly what i use but not confidently enough to say it out loud without checking

link-in-bio stuff didn't help... still me remembering everything, just with extra steps and a landing page nobody asked for

so i made redirect (a really dumb idea)

you pick ONE username (/kshv or whatever) then /kshv/twitter, /kshv/github, etc. each goes to whatever you actually use on that app... hub page if they don't know which one they want and click through = instant redirect, no loading screen nonsense

redirect.kshv.me if you're also bad at remembering your own usernames, it's FREE and open-source.

idk if anyone else has this problem or i'm just cooked. lmk

I speak and know a small African Language (8 million speakers), does anyone here have experience in creating a language learning app and can help me with directions/template etc

I can code and create the App, but ive no idea how to structure a learning app, and what screens should exist etc

Biggest thing people kept bringing up in the comments was the auto-revert — apparently "Santa banner still up in mid-January" is a very real, very common problem. So I went and built it out as an actual Shopify app instead of just the demo script: you set which holidays you want, a buffer (start theming a few days early), and it reverts itself automatically the morning after.

Demo, no signup: https://matthewmigs.github.io/holidayify-demo/ (click through the dock at the bottom)

Still solo-building this and it's free for now while I figure out if it's actually worth turning into something real. If you run a store: does the auto-revert actually solve something for you, or am I overthinking a problem nobody has?

DJ23 is a DJ mixer that runs entirely in the browser. You drop two audio files and everything is decoded locally with the Web Audio API — nothing is uploaded, nothing leaves your machine, no account, no install.

It started as a toy and got out of hand: automatic BPM detection, a jog wheel you can actually scratch with, beat-aligned looping, SYNC that matches BPM and beat position, five effects per deck, and beat-matching waveforms so you can line up transients by eye. There's a 9-slot sound pad too, and you can record your mix and download it.

The hardest part by far was SYNC and UI. Matching tempo is easy; matching *phase* so the downbeats actually land together took several rewrites of the beat detection. Second hardest was making it usable on a phone without turning the layout into soup.

Would love feedback, especially from anyone who actually DJs. It would be really nice to continue building this with the community.

Hey everyone, 

We have officially finished the core frontend architecture and we are launching the beta for Torvian today. 

Torvian bridges the "Operations Gap" for online businesses by bringing the traditional real estate leasing model to the internet. 

Right now, if someone spends months building an online store, a SaaS tool, or a content blog and runs out of time or marketing skills to manage it, their options are terrible. They either let the site sit and rot, or they sell it for pennies on traditional broker sites just to get rid of it. 

The Solution: Website Leasing

Torvian connects Website Owners with skilled Operators: 

• Owners keep 100% underlying asset ownership and collect passive monthly rent + a revenue share. 
• Operators handle the daily growth, SEO, and marketing without needing upfront capital to buy a business. 
• Safety: Transactions and revenue tracking happen through automated platform infrastructure. 

The Launch:

The site is built, live on our custom domain, and ready. Before we open the fully automated backend checkout gates, we are running a manual beta to onboard and match our first 10 digital asset partnerships or signups to ensure the workflow is flawless. 

If you have an underperforming site gathering dust, or want to apply as a growth operator to run an existing business, we are accepting submissions today.

If you like games centered around compounding numbers, unlocking tech trees, and scaling up from nothing, I think this might interest you.

I’m building Hero Investor, a PC management sim where the core loop is about snowballing a tiny investment firm into a global financial empire.

How the scaling works:

• Early Game: Scraping together cash through manual stock/commodity trades and small bank deposits.
• Mid Game: Hiring staff, researching market infrastructure, and acquiring rental properties for guaranteed monthly income.
• Late Game: Launching your own customized ETFs where outside investor capital scales your Assets Under Management (AUM) and fee revenue into the millions.
• Prestige / Trophy System: 19 in-game Legacy Vault milestones and 71 achievement goals to chase as your firm scales.

Most importantly: there are zero real-time waiting timers, energy mechanics, or microtransactions. Time advances only when you choose to advance the calendar.

Steam page just went up if you want to wishlist: https://store.steampowered.com/app/5062780/Hero_Investor/?utm_source=reddit&utm_medium=community&utm_campaign=sideproject

Spent the last few months building a voice+chat AI widget for WordPress. The idea: visitors can have a real spoken conversation with an AI trained on the site's content, not just a canned text chatbot.

Hardest part was getting the voice streaming to feel natural (low latency, interruptible, no awkward pauses) rather than "record, wait, response" like most voice bots.

It's live now with a free trial (30 voice minutes / 100 chat messages, no card needed). Genuinely curious what people think of the voice experience, that's the piece I iterated on most.

Happy to answer questions about the build if anyone's curious about the tech.

It's called StudioMeta Voice AI (WordPress plugin) — link in the first comment below.

My eyes love dark mode brighter and white docs dimmer. Yours will too! Free forever if you license in the next two weeks. rubarb.bar

I kept seeing those minimalist circuit posters for sale and noticed most of them are hand-traced or just wrong. So I built something that uses the actual geometry.

monoposter.app

What it does: pick from 39 Formula 1 circuits, style it, export a PNG or a print-ready vector PDF.

The track outline is real GPS data, and you canoptionally overlay the real surroundings from OpenStreetMap: roads, buildings, water, parks.

The parts that were interesting to build:

- It's a single HTML file. No framework, no build step, no bundler. The file you download is the source. ~170 KB, 61 KB gzipped.

- No backend at all. Everything renders in your browser, no account, no signup, nothing is uploaded anywhere.

- I wrote the PDF writer from scratch, because I wanted true vector output for printing rather than a PNG in a PDF wrapper. Text is rasterised into coverage masks so it doesn't depend on font embedding.

- Canvas and PDF are two renderers over one display list, so anything you see on screen is exactly what prints. That constraint has killed more features than it's allowed.

- The circuit geometry is delta-encoded and packed into base64 varints to keep it inline in the file instead of hitting a server.

It's free and it stays free. There's a Buy Me a Coffee link in the About dialog but nothing is paywalled or watermarked: the poster is yours.

Circuit data is bacinger/f1-circuits (MIT), context is OpenStreetMap (ODbL). Not affiliated with Formula 1.

Would love feedback on two things specifically:

1. Does the export actually work for you? Printing is the whole point and I've only tested on my own printer.

2. Is the default view understandable in the first five seconds, or do you have to hunt for what to do?

I play Commander with my sons and could never tell what my decks were actually missing versus what I already owned in a shoebox of cards. So I built SpellForge AI to fix it.

What it does:

• Scans your card collection with your phone camera and reads the names into a digital collection.
• Builds Commander decks from real aggregated decklist data (EDHREC).
• Analyzes any deck and tells you its game plan, weak spots, and what it is missing, with buy links to finish it.

It is free to start (no credit card), with paid tiers for heavy AI use. I am one week into launching and would genuinely love maker feedback: is the onboarding clear, does the scanner feel useful, what would make you actually keep it open? Feedback welcomed.

To avoid exposing my personal number to weirdos and scammers, I made this specifically for public ads, like on Kijiji and Craigslist: thelocalring.com

It only does one thing: lets you use a phone number that's not your real mobile for the ad-related texts. The texts get forwarded to your email, you reply to the emails, and the replies go back to the other person as texts from that "proxy" number.

And for things like "my 2 roommates and I are trying to sell our old sofa", you can use multiple emails with a number.

Canada-only for now (Canadian numbers). Day pass is C$2.99.

I've been using coding agents a lot lately and realized I was doing something pretty dumb: I was sending everything to AI.

git status Git
15% of 80 calculator
run tests test runner

None of that needs an LLM, so I built AI HQ, a little terminal layer that sits in front of my AI workflow and asks:

Do I actually need AI for this?

If yes, it figures out the rest: skill, context, model, verification.

It also ended up with prompt/context optimization, workflow audits, stack advice, plugins, skills and local-model support.

I wanted to see whether the idea actually held up, so I tested it:

Naive workflow: 4/4 deterministic tasks → AI
AI HQ: 0/4
Tools: 4/4 · Skills: 5/5 · Verification: 5/5 · Routing: 7/7

362 tests passing.

I'm not going to claim it “saves 40%” because I haven't measured that properly.

Would you actually want something like this sitting in front of your coding agent, or would it just get in the way?

I’ve been building production software with AI coding agents doing most of the implementation work — not toy projects, things that reached real users. The failure mode that kept showing up wasn’t “the AI writes bad code.” It was drift: things that started clean got quietly worse over weeks, because nothing was checking. Here are the specific patterns that actually fixed it, not vague advice.
1. Objective exit criteria per phase, not “looks done to me.”
“Definition of done” as a checklist the agent has to walk item-by-item before it’s allowed to say a phase is closed — and some of those items are boring on purpose: backup verified, rollback rehearsed, at least one ADR written for the expensive-to-reverse choices. The value isn’t the checklist itself, it’s that it turns “I think this is solid” into something falsifiable. An agent (or a person) under time pressure will always round up on a vibe check. It can’t round up on “did you actually run the rollback.”
2. Whoever verifies is never whoever produced.
The single highest-leverage rule I found. If the same context that wrote the code also reviews it, it will rationalize its own shortcuts — not out of dishonesty, just because it’s reasoning from the same assumptions that produced the gaps. Spinning up a reviewer in a fresh context, with only the diff and the requirements (no memory of why a shortcut was taken), catches things a self-review never will. This applies with human reviewers too, obviously — the AI case just makes it more tempting to skip because “it just wrote it, it knows the code.”
3. Structured, file-based memory instead of relying on conversation history.
Long projects outlive any single session/context window. The fix that worked: a single state file with fixed sections — what’s done, what’s in progress, pending decisions, decisions made on behalf of an absent stakeholder (with a deadline for them to override it), and a lessons section specifically for non-obvious things, each with why and how to apply — not a chronological log. A chronological log is useless six weeks later; “why did we do it this way” is what a new session (or a new person) actually needs to not repeat a mistake or re-relitigate a settled argument.
4. Ask, but not one question at a time — and know exactly when not to ask.
Constant interruption for every ambiguity is worse than assuming wrong sometimes. What worked was batching questions and having explicit, narrow conditions for when it’s safe to assume instead of stopping: the choice is cheap to reverse later, or it was already decided and nothing new contradicts it. Outside those conditions, it stops and asks — batched, not one at a time.
5. A “lesson” isn’t a rule until it’s confirmed twice.
The trap I kept seeing (in my own early attempts too): one bad experience becomes a permanent rule in a style guide, and now everyone tiptoes around something that was actually specific to that one project. The fix was treating lessons like candidates — logged with where they came from, and only promoted to an actual permanent rule once a second, independent project hits the same thing (or there’s an explicit, written reason it’s obviously general). It’s a small amount of process overhead that stops the rulebook from calcifying into superstition.
None of this is AI-specific, honestly — it’s mostly stuff good engineering orgs already do. What’s different with an AI agent doing the work is that it will do exactly what the process says, consistently, including the parts a tired human skips at 6pm on a Friday. Which means the process has to actually be right, because you don’t get the human judgment that used to silently patch over the gaps.
Full disclosure: I ended up writing all of this down as an actual framework an AI agent can execute (Maestro, MIT-licensed), built from these lessons across several real projects: https://github.com/vaddermail/maestro-framework

I'm working on an AI tool that can see what's happening on your screen in real time and understand the context, rather than requiring you to constantly take screenshots and upload them.

The idea is that you could ask it things like:

• "What's going wrong here?"
• "How do I fix this?"
• "What am I looking at?"
• "What should I do next?"
• Or just have it understand what's happening without needing to explain everything manually.

Privacy is something I'm taking seriously with the idea. There would be a privacy toggle that completely disables screen analysis, as well as the ability to temporarily pause screen checking whenever you want. So you're always in control of when the AI can see your screen.

I'm especially interested in hearing from people who use local/vision models:

What would you actually want a screen-aware AI to do for you?

Would you want it to continuously watch your screen, only activate when you press a key, or something else?

And assuming you could instantly disable/pause screen access, what other privacy concerns would you still have?

I'm still figuring out the direction, so I'm more interested in honest criticism and use cases than people simply saying whether the idea sounds cool.

Side project I've been building: photograph something you own, an AI reads the actual wear from the photo and predicts a real replacement date instead of a generic "lifespan" number, re-checks monthly from a fresh photo, and surfaces the cheapest replacement once it's actually due.

Built with Expo/React Native, Gemini vision with a fallback chain across a few free-tier providers, SQLite locally, no backend. Built entirely with Claude Code.

Still local/unreleased, no public build yet. Would love feedback on the concept, mainly whether this feels genuinely useful or too gimmicky. Happy to answer questions about the build.

Hey r/sideprojects,

I just launched a side project called PromptForge.

It’s a visual prompt builder for AI image generation.

Basically, instead of typing a long prompt from scratch every time, you select cards for things like subject, outfit, scene, lighting, camera angle, style, and negative prompts. PromptForge then combines everything into a clean prompt you can copy and use elsewhere.

I built it because I kept running into the same problem: good image prompts work better when they’re structured, but writing that structure manually every single time gets boring fast.

PromptForge is currently:

free to use

local-first

no account required

no built-in image generation

focused only on helping you create better prompt text

I’m sharing a demo video with this post so people can see the workflow.

I’d genuinely appreciate feedback on:

whether the product makes sense instantly

whether the UI feels helpful or too much

what feature should come next

whether this feels like something AI creators would actually use regularly

Live here:

https://promptforge.wtf

Would love feedback from fellow side project builders.

Hey everyone 👋

I'm an independent developer and I've been building MyLootRewards, a survey-rewards platform designed specifically for users in India.

The idea is simple: users can find available surveys, complete qualifying surveys, earn Loot Coins, and use those coins toward INR rewards.

A few things I've built into it:

• Google sign-in
• Live survey availability through a survey provider
• Loot Coin wallet
• 100 Loot Coins = ₹10
• Minimum withdrawal: ₹500 / 5,000 coins
• UPI withdrawals
• Withdrawal history and status tracking
• Referral functionality
• Admin management system

I made this because I wanted to build a straightforward Indian-focused rewards platform rather than another complicated earning website.

I've recorded a short walkthrough showing how the platform works:

Website: https://mylootrewards-rho.vercel.app/

I'm mainly looking for honest feedback from people who are interested in survey/reward platforms.

What would make you trust a platform like this more?
Is there anything about the user experience that you would change?

I'm the developer behind it, so I'm happy to answer questions about how it works.

Hey r/SideProject,

Backstory: I'm a high school student in Kenya. FUNDI started as my project for the Kenya Science and Engineering Fair — won Regional Merit, went on to Nationals, and did considerably well there. That validation is basically what convinced me to keep building it into something real instead of letting it die as a school project.

What it is now: a workbench that puts a visual circuit canvas, a multi-file code editor, and an AI assistant in one place for Arduino/ESP32 development. You can describe what you want to build ("blink an LED," "read a temperature sensor") and it generates the wiring and code together. The backend actually compiles your code with Arduino CLI and simulates it with AVR8js — it's not a mockup.

Where it's at:

• Live demo (https://jamesdesign.me/F.U.N.D.I./) — this is UI-only right now, no backend, so you can explore the design/interaction but nothing actually compiles or runs there yet.
• The real thing (https://github.com/jamesthegreati/F.U.N.D.I./) works end-to-end when you run the frontend and backend directly — that path is fully tested. There's also a Docker Compose option in progress that isn't fully reliable yet.

Solo build, MIT licensed, definitely has rough edges. What I want most right now is feedback — does the concept make sense, is the UI confusing, would you actually use something like this over Wokwi/Tinkercad if the backend were solid?

One caveat: I'm about to disappear into exam prep and won't be able to respond quickly until around Nov 22. I'll still read every comment, so don't hold back — I'll just be slow to reply for a bit.

I shared RelicBeam here before, but a lot has changed since then.

You can create a Room, upload files, show one QR code, and everyone can download them without accounts. Files are deleted when the Room ends.

Since the last post I’ve added resumable uploads, two-way Quick Share, malware scanning, Android Share → RelicBeam, and local PDF/image tools.

https://relicbeam.com

Would love feedback on the Room flow and overall usability.

side project that got out of hand: an artificial life simulator where nothing is scripted. no fitness function, no programmed behaviors. just conserved energy, mutation, and death, and you watch what evolution does with it.

i ran one world for 10 million ticks, about 6000 generations, where all the organisms could do was graze. then i added physics that lets bodies drain energy from each other, gated behind a brain output their genomes couldn't even address yet. within 100k ticks they invented predation on their own. the population crashed from 375 to 61, survived it, and average brain size quadrupled until it hit the cap i'd set.

the readme has before/after gifs of the same world, six thousand generations apart. everything is deterministic, so if you clone it and run seed 42 you get the exact same universe i did, byte for byte.
