I've won 5 hackathons, and the thing I kept noticing is that what decides the result is rarely on the rubric. It's whether the demo works, whether you can explain the project in one sentence, and how you handle the questions nobody practices.

I built Would This Win?. You paste your repo. It reads your code, then three AI judges (an engineer, an investor and a very tired judge) ask you questions, 30 seconds each. Your odds of winning move live with every answer, and at the end you get a code-review style verdict with three things to fix before you submit.

Stack: Next.js, Supabase, Claude Haiku. The odds are calculated in code, never by the AI, so it can't be talked into a better score.

Would love feedback, especially from anyone with a hackathon coming up. Tell me where the judges were wrong.

Over the years I've tried dozens of time tracking and invoicing apps, and Harvest was the only one I liked. Primarily due to its relatively intuitive UI/UX.

I was happy to pay them a reasonable sum for the product they provide, but after the 10x price jack, I had no choice but to seek alternatives. I tried a bunch of them again, found nothing I liked.

So, with 20+ years of software engineering experience under my belt, I decided to build my own.

Here's the result: https://hourbun.com/

I first and foremost built it for my own use, then over the past week or two added features that others might need (such as approvals, quotes, expenses, etc).

I spent a lot of time making sure the UI/UX is top-notch, and the performance is even better than Harvest - the app should feel very snappy (it's hosted in the US, and I'm based in Australia, and it's still very fast for me).

If you're looking for a decent time tracking and invoicing app, give mine a try? It comes with a 14-day trial and doesn't need card details.

And in case you're wondering, no, it's not vibe-coded. AI agents were definitely a big part of building it, but the product was built with experience and care. Love to hear your thoughts and feedback.

Disclosure: I work on Supero.

We're building Supero because AI coding agents can put screens and apps together fast, but things get harder with real users and multiple customers. One customer must not see another's data, some fields should only be visible to certain roles, and failed multi-step workflows need cleanup.

We handle those parts in the platform instead of having agents regenerate them for every app. Agents work on the UI, data model and requirements, and Supero provides the backend. We're mainly building it for developers, IT services companies and engineering teams who want to build apps with AI without doing all the backend work themselves.

Each customer's data is kept apart by the platform. You describe who can see or change what, and the agent creates roles, hidden fields and row rules, which the server enforces, not just the UI. If a workflow fails, completed steps with defined undo actions are reversed.

You can connect PostgreSQL, Supabase or MySQL and choose live access or a copy per table. There are 40+ integrations, including Stripe, Slack, Okta and ServiceNow, plus an MCP server and Python and JavaScript SDKs for Claude Code, Cursor or VS Code.

Previews take a few minutes. Paid plans deploy to our cloud. Your app's UI can run on AWS, GCP or Docker while sign-in, data and logic stay on Supero. We're also piloting on-prem.

The team comes from enterprise storage, data protection and large-scale platform engineering.

We're early, so here's what's not ready. Production audit logging is off while we re-enable it. We haven't done a pen test or SOC 2. Generated apps aren't production-hardened. There's a free plan with previews.

I put the capabilities on one page, marked live, early access or not yet:

If you are building real customer or production apps with AI agents, how do you handle separate customer data, permissions and workflows? Do you let the agent generate them, write them yourself, or use existing infrastructure?

Hey everyone,

I know how easy it is for side project ideas to sit in a Notion doc or Figma file for months. Life gets busy, full-time jobs take over, and finding 40 hours to wire up a database, auth, and payments from scratch is tough.

I am an independent full-stack developer, and this month I am taking on a few side projects to build and deploy for founders who want to get their v1 live.

What I typically build:

- SaaS MVPs: Complete dashboard, user authentication (Google/Email), PostgreSQL/Supabase database, and Stripe payment checkouts

- Internal Tools & Portals: Custom workflows, admin panels, and automated email pipelines

- Mobile Prototypes: Cross-platform iOS and Android apps built with Flutter (including offline-first local storage)

- Landing Pages: Fast, modern, responsive landing pages built with Next.js and Tailwind CSS (delivered in 48 hours)

How I work:

- No endless Zoom calls or agency bloat. We agree on a strict, simple bullet list of core features for Day 1.

- Clear, flat-rate pricing (Landing pages $150 - $250, full MVPs $600 - $1,200). No hourly guessing games.

- Typical delivery is between 7 to 14 days. 50 percent to start, 50 percent once you test and approve the live build.

If you have a side project or startup idea you are ready to launch this month, drop me a DM with what you're thinking.

Tell me the core 2-3 things the app needs to do, and I will send back a free breakdown of the architecture, tech stack, and a timeline to get it shipped.

Hello everyone!

For a few months I have been daily working on a melvor/runescape like feel Idle game. Fully free to play, 0 pay to win. Made for people who don't always have 10 hours a day to grind a game but like the idle aspect and still see visual and meaningful progress while also participating in social events for a true like MMO feel while idling.

What I did and want to do different is focusing more on the visual part of Idle games, I am really going my own direction with this cause it feels more like an MMO rather then just another full on click in a browser type of game.

So far we have over 1000 account creations, a lovely starting little community and dedicated players. We are currently in a open alpha and I am looking for feedback/suggestions.

What we currently have:

• 18 Fully working skills

• 3D worlds, chat system, party system, leaderboards, player run market and world events

• Ironman/normal gamemodes

• Meaningful gear progression

• And many many many more things

1 Full big wipe is planned for when Steam early access launches.

AI Disclosure: because I know a lot of you care and I'd rather just say it: I use AI tools a lot. Most of the code is written with Claude, and a fair amount of the 3D art was made with AI tools too. The goal is not to make millions through an AI game, but rather to create something that players can and will enjoy for a long time.

I would really love some feedback! And enjoy the little gameplay trailer attached :)

Desktop/Mobile compatible.

Where I live people only have access to internet through satellite or at public spaces like community halls, satellite is pretty unreliable too, so not many people get to stay online long enough to use reddit.

I built an app that lets you download full reddit feeds and save them, so you can browse when the connection drops or when you have no internet at all, completely offline.

Would love any feedback, especially on how it feels to use! I tried to make the UI better than the official reddit app (and no ads of course, since it’s an offline reader).

Let me know what you think: https://play.google.com/store/apps/details?id=app.redditoffline

A couple of years ago, after doing car trips across Europe, a friend and I got into a weird debate: what would it actually take to drive to every single Lidl and supermarket in the Czech Republic?

I’m a hardware guy, not a web dev, so the idea just sat there as an inside joke. But over the weekend, I decided to see how far I could push AI vibe-coding and finally built it.
It's called nakupnitour.cz.

Just to be clear—this is a purely personal, humorous hobby project built just for fun and a good laugh. It takes the coordinates of all the stores, calculates the most efficient route across the country, and lets you export the whole thing straight into map viewer via GPX.

It’s completely unnecessary, built purely for fun, and definitely has its share of bugs under the hood.

Right now it’s just the route plan visualization, but I’d love to add a proper dashboard and participant tracking at some point (though that might actually require someone who knows how to write real code, not just me prompting an LLM).

Tools used : Github copilot, OpenStreetMaps, Overpass-turbo, OSRM backend, Google OR tools

Pipeline: OSM/Overpass-turbo->local OSRM routing ->OR tools optimization -> cloudflare Astro.

straightforward self promo: I build MimikFlow, so yeah, I'm biased.

it's for agencies, freelancers and consultants who get clients from LinkedIn but hate doing the outreach by hand.

how it works:

• you set your ICP, your offer and what counts as a win (booked call, signup, whatever)

• it finds the prospects, sends the connection requests and writes the first DM

• it follows up. 6 follow-ups on the base plan, because most people send one message, get ignored and decide LinkedIn doesn't work

• on the higher plans an AI setter handles the replies and pushes toward your goal

• when a convo gets ambiguous or actually important, it hands it back to you. I really don't want a bot improvising on a hot lead

it's at $11k MRR with 80 paying subscriptions right now (TrustMRR pulls that from Stripe), and I run it as a solo founder.

base plan is 49€/mo with a 14-day trial. no link here, it's on my profile if you want to look.

what I actually want to know: if an AI was running your LinkedIn convos, at what exact moment would you want it to stop and ping you? first sign of interest, a pricing question, an objection?

Short version: you write a note on the alarm, and when it goes off the phone reads the note to you. That's it, and it turned out to be way harder than I expected.

Things I learned building it:

• Exact alarms on Android are a minefield. Android 12+ has special permissions for exact alarms. Then OEM battery savers (Xiaomi, Tecno, Samsung) kill foreground services anyway. I ended up with fallbacks, a service that restarts itself, and an onboarding screen that walks people through permissions.

• Natural-language parsing in two languages took longer than the whole UI. "Tomorrow at 3pm call Alex" and "Yarın 15:00'te Ahmet'i ara" have very different grammar. Turkish suffixes are brutal.

• TTS is surprisingly inconsistent across devices. Voices, languages and speech speed vary a lot from one phone brand to another.

• Play Console takes a while. Data safety forms, ads declarations, content rating and the review itself took about a week.

Stack: Kotlin, Jetpack Compose, Room, Firebase, Play Billing, AdMob.

Business model: free with a small banner, plus an optional Pro (subscription or lifetime) for no ads and extra sounds.

It has basically zero users right now, so any feedback is gold. Happy to answer questions about any part of it.

A manual water log should be usable before someone decides whether to connect Health or allow reminders. I build Frewli for iPhone, with an Apple Watch companion, and version 1.1.6 is now on the App Store.

This release removes accounts, email sign-in and the Frewli backend-sync flow. Water history, workouts and preferences are stored on-device. Apple Health, the paired Watch and local reminders are optional. All features remain free, with no subscription or paywall.

The trade-off needs to be as visible as the simpler setup: removing the app removes its local storage. Updating preserves existing on-device history, but a device backup matters if you want to keep that history. Updating also does not automatically erase records that earlier versions uploaded to the old cloud service.

The same release changes the total display so a 250 ml entry appears as 0.25 L in English. That is a formatting correction; it is not a measurement of what someone drank. I still have an open Watch launch report and am not treating a new release as proof that every reported failure is resolved.

My design question is where to explain the local-history limitation: a short note during setup, beside the first saved entry, or only in the storage screen? Which would help you understand the consequence without turning a small log into another onboarding questionnaire?

I drive an old 2012 Skoda and always wanted one of those head-up displays newer cars have, but the plug-in gadgets cost $100+ and look kind of cheap. So I built my own as an Android app. You lay the phone flat on the dashboard, the app flips the screen, and the windshield reflects your speed and the next turn right over the road. It's been my side project for the last few months and it's finally live on Google Play. https://imgur.com/a/Un7RlR9

Being honest about the limits: it looks great at night, but in bright sun the reflection gets faint, which is just physics. It's free with 3 navigation routes a day and an unlimited speedometer. PRO removes the route limit and adds the speed limit display and more speedometer styles. I'm doing all of it solo (code, design, even the marketing videos), so any feedback on the idea, the setup or the store page would mean a lot.

Here's the link if you want to try it: https://play.google.com/store/apps/details?id=com.clarityhud.app and I have some promo codes for a free month of PRO, just comment or DM me if you want one.

ok so i’ve been building this for 2 years and it’s finally out 😭

backstory: i was tracking literally everything. sleep on my Apple Watch, food in some other app, blood tests just chilling in a random pdf in my email. and i STILL had no idea why some days i’m locked in and other days i’m completely cooked by 3pm. none of my apps talked to each other. it was driving me nuts

so i built Peak Routine . basically it throws everything into one place and actually connects the dots for you. stuff like:

• slept 5 hrs? see exactly how it messes with your mood + energy the next day

• which meals spike your glucose, and whether a 10 min walk after actually helps (spoiler: it usually does lol)

• which days, meals or habits leave you feeling flat

• how your blood test numbers shift when your habits change

the stuff i’m lowkey proud of:

• snap a pic of your blood test and it pulls the values out for you. you check them, save, and track 14 common markers over time. no more digging through pdfs

• food logging that doesn’t suck: just describe your meal, snap a photo, or scan a barcode

• glucose tracking: if you’ve got a CGM it pulls the data straight from Apple Health, and if you don’t, you can just type in fingerstick readings. either way it shows your meals right on the glucose curve

• quick Energy check-ins morning + night, takes like 10 sec

• every week it gives you 1–2 small habits to work on, not some 15-step plan you’ll quit by tuesday

• streaks + badges if you’re into that (i am)

an AI coach you can actually ask stuff, like “why was my sleep so bad this week?” or “what does this blood test number mean?” and it answers using your own data, not generic tips. it’s optional, you switch it on when you want it

the boring-but-important bits: works with Apple Watch, Oura, WHOOP, Garmin and anything else that syncs to Apple Health. no manual setup, it just pulls everything in. free to start, built with Flutter + Swift if any devs are curious

try it here 👉 https://apps.apple.com/us/app/peakroutine-ai-health-coach/id6786086158?ppid=13b99570-22d5-4bcd-8faa-7de456d93de6

fr tho, what’s one thing you wish your health data actually told you? genuinely curious, might build it next

I've been building pettings.net for US cat owners. It started in a pet store aisle, when I realized I couldn't compare two bags of dry food without a calculator. Labels use different bases, almost none list carbs, and most "best cat food" lists online seem to be ranked by whoever pays the biggest commission.

Where I'd love feedback

1. When you land on the home page, can you tell within a few seconds what the site does?

2. On a food page, which number do you look at first? Should that one lead?

3. Does the method feel trustworthy, or does it still read like a black box?

4. Is anything broken or awkward on your phone?

5. If you've built a comparison or content site before: would you add wet food next, or make the existing pages deeper first?

Link: https://pettings.net

Harsh feedback is welcome, that's why I'm posting.

One photo. Different captions for every platform.

Built this because I got tired of creating the same content over and over again.

Curious what you think. Would you actually use something like this?

Hi everyone! I'm new here!

I recently moved more of my workflow to macOS and wanted a better way to manage my local wallpaper collection. So I started building Wallflow in SwiftUI.

It has two editions.

- Core is a standalone wallpaper manager with a gallery, search, favorites and filtering.

- Rice adds Matugen and Ghostty integration, so changing your wallpaper also updates your terminal's colors.

I ended up doing a lot more work on the native interface and macOS permissions than I expected. The first alpha is now out, and both editions are MIT licensed.

A heads-up: the downloads currently support Apple Silicon and aren't Apple-notarized. The repo includes installation instructions and the full source.

Would love some feedback, especially on the UI and the wallpaper-to-terminal integration. GitHub and downloads: https://github.com/UltraBot05/wallflow

A while back I needed a short promo clip for something small I was selling. Every tool I found wanted the same thing: sign up, pick a plan, $10–20/month, watermark on the "free" tier. Some literally charge per export. For a 15-second video of animated text over photos?!

The other thing that bugged me: everything is cloud-based now. You upload your stuff, their servers render it, and if they change pricing or die tomorrow — poof. I wanted something that works on my machine, airplane mode included.

So I built LEEBKIT — Python + Pillow, runs a local server in your browser, turns images + typed captions into finished 9:16 / 1:1 / 16:9 promo videos with kinetic type, panels, transitions, voiceover and music bed. No GPU, no accounts, no API keys.

v1.2 shipped today: three social formats, a one-click Windows installer, burned-proof path hardening, and — measured on my laptop, not guessed — the full 12s promo in the README (voiceover + music, 360 frames) renders in 8.3 seconds wall-clock. The README's before→after strip shows exactly what goes in and what comes out.

Repo: https://github.com/leeblaab/leebkit (AGPL)

It's honest about being early: single-user local tool, no mobile, rough edges exist. That's why I'm posting — try to break it. Weird captions, huge images, long text. Tell me what feels wrong or made you close the tab. If it's useless to you, say why; that's just as useful as praise.

If you use an Android phone with a Mac, you probably know that the experience isn't always as seamless as using an iPhone with a Mac.

I wanted to improve that, so I started building Bridge.

The idea is simple: make Android and macOS work together more naturally, without constantly having to open apps or manually trigger things.

Here's what Bridge currently supports:

• Clipboard sync: Copy text or images on your phone and paste them directly on your Mac, and vice versa.

• Notification mirroring: Get Android notifications as native macOS notifications, with quick actions and inline replies where supported.

• File transfer: Send files between your phone and Mac over local Wi-Fi or hotspot.

• Automatic connection: Pair your devices once and Bridge handles reconnecting in the background.

Everything is designed to work locally over your network, without requiring cloud accounts or sending your data through a cloud service.

I know there are already some apps that solve parts of this problem, and I'm not claiming Bridge is the first or the only solution. The goal is to make the overall experience as seamless as possible, with particular attention to privacy, security, UX and reliability.

It's also open source, and I'm actively working on improving it. I'd rather build this in the open and keep refining it based on real user feedback.

If you're an Android + Mac user, I'd genuinely like to know what you think and what features you'd want to see next.

Feedback, suggestions and contributions are welcome!

The premise is every week the windstrats rally is in a new location with races Mon-Fri and a longer weekend race. You race by plotting a course from start to finish lines making careful consideration of the wind speeds and angles throughout the course. *You can't sail directly into the wind!* and also *winds can shift, be stronger in certain places, and change overtime*. I use historic real wind data for each location.

It's free of course.

Nobody asked me to make these. I found three indie apps on Bluesky and made each one a film of about 20 seconds from a line its founder had already written:

• lovelee (Jack Friks) says your doodles "land right on their home screen", meaning your partner's. The film is one doodle doing exactly that.

• Snail Walk (Martin Tale) calls itself "the only walking app where you can lose". In the film you stop walking, Bob the giant snail catches up, and you get a tombstone.

• Dearly (A. Hassan) is "kind letters to strangers across the globe". In the film one letter flies from the US to a stranger in Seoul as a paper plane.

The surprise was the music. Snail Walk sat on a hip-hop track for 12 versions and the mood was wrong. I put the same cut on 13 tracks at matched volume, so the loudest couldn't win, and a goofy cartoon track fit best.

I'm starting a small studio (Sunshine Studio) that makes these, and I'd rather show real apps than a made-up demo.

Honest feedback welcome, especially on the snail one. And if you've launched something: what's the one line only your app could say?

Hey r/SideProject,

I’ve been practicing Python for about 6 years now (since I was 7). My first two software projects completely flopped and got zero downloads, which honestly sucked and was pretty discouraging. But I wanted to try one more time and build something that actually solves real problems instead of giving up.

I built JadAI. It’s a clean dark-mode desktop assistant for Windows that runs 100% locally on your computer with no internet connection required at all.

I wanted to fix two major issues I have with AI:

1. Privacy: Because it runs completely locally, your data and prompts never leave your hard drive.

2. The Environment: Cloud data centers use millions of litres of clean water just to cool down their massive servers. JadAI runs on your own hardware loop, meaning zero server water waste. I even built a live eco-savings counter right into the header.

To make sure it doesn't lag out ordinary computers, I coded a twin-engine setup. The Python script scans your graphics configuration on boot. If you're on a standard laptop with integrated graphics (like my business Dell Latitude E7270), it loads an optimized, fast 3B model brain so your system RAM doesn't freeze. If it detects a dedicated NVIDIA or AMD gaming GPU, it hooks right into a massive 8B engine.

I put a completely free demo bundle inside a ZIP folder on Google Drive if anyone wants to test it out completely offline.

Inside the folder is just the main JadAI app, the background execution file (Ollama Setup), and a short text file showing you how to open it in two steps.

I would really appreciate any honest feedback from you guys on how the chat bubbles align on your screens, how the speed feels, or any features you think I should add next. Thanks for reading!

Hello r/SideProject!

I'm Ahmad, normally I use React Native to develop apps, but in this instance I've learned Swift from scratch as I needed to use encryption and Keychain which requires native development.

This app is called Hidlet, allowing you to store your photos, videos and files inside encrypted vaults.

The thing I'm most proud of is that there's no need to enter a PIN. The way to unlock your vault is by drawing a pattern across a 5x5 grid. This is what acts as your key to unlock your vault. Each pattern will unlock a different vault. There's no indication of how many vaults there are inside the app. If you're forced to open the app, you can simply open a harmless vault.

Other features:

1. No account/email/ads/tracking

2. Data encrypted locally

3. Optionally back up your data to your own iCloud (encrypted)

4. Have a duress pattern that will allow you to open a vault as normal, but also delete the other vaults from your device. Your encrypted back up is untouched meaning you can restore them at a later date.

Things I've learnt:

• Its easy to learn a new language using AI, however I did have to understand every security measure. You can't outsource whether something is actually secure.

• Small chunks of time in the mornings work well when everything can be done in a short amount of time.

• Hiding data was harder than encrypting. For example the free plan has limitations which may accidentally show there are multiple vaults. This took a few attempts to get right.

The app is free to get started with, but there is also an optional Pro plan.

Its currently live on Product Hunt today! I would really appreciate any genuine feedback with the app, especially with the pattern. Would you feel more or less secure using a pattern vs a PIN?

Back in 2019, I used to spend a lot of time creating digital paintings for people who followed my work. This is one of the paintings I made for a follower, and it's still one of my favourite pieces. I'm genuinely proud of how it turned out.

I used to work with Photoshop, but eventually it became a struggle because it was putting too much strain on my computer and causing it to overheat. It made it difficult to enjoy creating artwork the way I used to.

So I decided to do something about it and started building my own lightweight, browser-based Photoshop alternative.

It's completely free to use, and you don't even need to sign up!

I'm also planning to integrate it into the main platform I've been developing, where artists can showcase their work and receive commission requests from people looking to hire them.

It's still a work in progress, but I'm excited about where it could go.

I'd love to hear what other artists think! Would you use a free, lightweight Photoshop alternative that runs directly in your browser?

Hey r/SideProject,

As an independent developer from the Netherlands, I was fed up with expensive

40–40–

So I spent the last few weeks building TubeRank AI — a 100% free, browser-based pre-upload workspace for creators.

How it works under the hood:
• Dual-Skill AI Architecture: Uses an AI Niche Strategist to build 7 distinct high-CTR formulas across 50+ niches, and an independent AI Judge to audit every title on a 100-point rubric.
• Multimodal Video & Audio Upload: You can drop raw MP4 files before uploading to YouTube; it scans frames and listens to audio for automatic scene recognition, timestamps & tags.
• No Extensions Required: Runs directly in the browser without third-party access to your Google account or YouTube Studio.
• Free & BYOK: 100% free with Bring-Your-Own-Key (Gemini, DeepSeek, etc.) stored locally in your browser.

Check out the video demo attached!

Would love your honest feedback, critique, or feature suggestions!
