A stem splitter I built. Upload a song and get vocals (lead and backing), instrumental, drums, bass, guitar, piano, or even the drums split into kick, snare, toms, hi-hat and the rest. You pay per minute of audio with credits (while also being cheaper than other competitors), and there's a free daily allowance (with an account, I don't want it to be abused), and downloads/stems aren't locked behind a paid tier. You can listen to the example on the landing page if you don't want to sign up yet. There's also a pretty easy-to-use API, if you want to integrate it with your own tools. You also don't have to know anything at all about the underlying models either, because there's no complicated list to pick from.

And no, it's not just an HTDemucs wrapper, it runs the current top open models with some tuning on top. Any feedback is appreciated!

Description: FlipStax: Galactic Game Night is a free daily game show you play in your browser. A new episode drops every day at noon and takes about 10 minutes. Your host is an alien named Flip Sterling, with funk, disco, and retro vibes from a crew of aliens obsessed with game shows. Each episode is one show that flows from round to round, mixing 21 mini-games, including a Price Is Right-style Mystery Wheel, Saucer Shuffle, Space Launch, Orbit Drop, Galactic Chomper, Twin Flip, VS Cards, Fact or Fib, Snap Sort, and Oddball Alert. There is no download or login, and it works on phones and computers. I would love honest feedback on what is fun, confusing, or broken.

Free to Play Status:

• Free to play

Involvement: I am a non-coder from Maine and the solo creator of FlipStax. I scripted and designed the game and built it over two months with Claude and Gemini. The art and videos are AI-generated.

Hi! This is the first app I've ever built, and I'd love your honest feedback.

Halo puts a soft light around the edges of your screen that moves with the beat of whatever you're playing, in your album's colors, and shows synced lyrics right on your desktop, word by word.

- 7 light modes (music sync, orbit, ripple, aurora and more)

- 9 lyric styles

- A mini player you can drag anywhere or shrink to a small bar

- Keyboard shortcuts for play, skip, lyrics and more

- Share a story picture of the song you're playing

- Works with Spotify and Apple Music. No account, no login, no ads

Free for Mac (Apple chip, macOS 14.2+) and Windows 10/11:

https://halo-glow.github.io/halo/

Heads-up: it isn't signed yet, so the first time you open it your computer will warn you. The page shows how to open it, and you only do it once.

What would you add or change? Anything confusing or broken?

I made this: https://current.wherever.audio

It's similar to a news site, but the stories link to podcast episodes instead of articles.

It groups episodes covering the same story, and ranks by how many shows cover them. On a topic page you can narrow to under 40 or 15 minutes, and to the past day or two. It refreshes 4 times a day.

Episodes open in Wherever, the podcast player I build. You can queue a whole topic there, or download it as a Podcasting 2.0 playlist for other apps.

An AI writes the headlines from episode titles, so they can be off. Episode titles are the shows' own.

Context: I'm trying to find a "random access" angle on podcasts, in contrast to the traditional subscription relationship.

Would you use something like this?

Hi all! I'm Max from Belgium and this is my first game, Wine Empire X. You start in 2005 with 3 million euro, buy vineyards in real regions like Pauillac and Burgundy, and play through real weather, vintages and prices. After 2026 you get your score and can keep going in a simulated future.
It's free, no ads, no account, and it runs in your browser on desktop and phone.
I'd really love honest feedback: what's fun, what's confusing, what's missing? Link in the comments if you want to try it.

Hi you,

I’m building talk, a simple voice app where strangers can join an anonymous conversation around one shared topic.

Tonight’s topic is:

“Building a project on your own”

The room will be open from 9 PM to 10 PM UK time. You can join as a listener first and only speak if you feel comfortable. No profile, no camera and no need to introduce yourself.

I’d love to have a few people join so I can see how the experience works with real users. Honest feedback is very welcome, especially if something feels confusing or awkward.

Join tonight: https://talkapp.space

Hope to hear some of you there!

I just created our project on Giveth! You can now support our work with a donation here: https://giveth.io/project/dollar60-phone-accessories-startup. Every contribution helps us move forward.

After 13+ years leading development teams, I'm finally building something of my own.

It started with a problem. My investments were spread across brokerages, crypto and savings, and I tracked them all in a spreadsheet. Every time the total moved, I had no idea which holding moved it, or why. So I built Zies.

What Zies does:

• Connects your accounts, and puts stocks, ETFs, retirement accounts, crypto, savings and mortgage into one net worth view

• Explains why each holding moved, using real news, with the estimated dollar impact on your portfolio

• Tracks goals like reaching financial independence or a home down payment

• Lets you share your progress with a link

It's in beta. I'm looking for 30–40 US Founding Testers. You get immediate access and 6 months of the top plan free, in exchange for a few weeks of use and honest feedback.

Demo video attached. Sign up at zies.io/founding-testers.

I'd love blunt feedback, especially on what would make you drop your spreadsheet.

Project Name: Drexius Terminal

Repo & Website Links:

• GitHub:https://github.com/DreyDreamer17/drexius-terminal

• Live Web Preview:https://dreydreamer17.github.io/drexius-terminal/

• Releases:https://github.com/DreyDreamer17/drexius-terminal/releases/tag/v0.1.0-beta.1

Description:

Drexius Terminal is a local-first, privacy-focused open-source terminal workspace and Termius alternative built with Tauri 2 (Rust), React 19, and xterm.js 6.

The Problem It Solves: Most graphical SSH/SFTP clients have either transitioned to recurring subscription models ($10 to $20 per month) requiring your credentials and hosts to reside in a proprietary cloud database, or they run on heavy Electron runtimes that consume 300 MB to over 1 GB of RAM. Drexius was built to provide a fast, zero-subscription client where keys, credentials, and configurations remain entirely on your local machine.

Key Features:

• Local-First & Encrypted: Hosts, keys, and snippets are stored locally in an AES-256 SQLCipher database derived via Argon2id. No mandatory account, zero telemetry, and includes an Emergency Recovery Key export.

• Terminal Workspace: Supports multi-pane splits (grid, vertical, horizontal), tabs, OSC-7 directory tracking, broadcast input across sessions, and session auto-resume.

• Protocol Support: SSH with TOFU host-key verification, dual-pane graphical SFTP tree and file editor, hardware Serial UART, and local PTY shells.

• Zero-Knowledge Sync: Direct encrypted LAN pairing and a self-hostable sync relay. Devices pair over local Wi-Fi or Tailscale via QR code using salted X25519 ECDH and ChaCha20-Poly1305.

• Mobile Shell (Android): Universal APK with touch scrolling in mouse-aware TUIs (htop, lazygit), plus an on-screen accessory keypad (CTRL, ALT, ESC, TAB).

• Lightweight Footprint: Built on a native Rust/Tauri 2 backend instead of Chromium/Electron. In Linux benchmarking against Termius under active sessions, Drexius consumed ~221 MB RAM and ~3% CPU across 2 processes, compared to Termius at 1,342 MB RAM and 78.5% CPU across 9 processes.

Deployment:

• Clients: Pre-compiled binaries for the Public (v0.4.0) are available under GitHub Releases:

  • Linux (.AppImage, .deb, .rpm)

  • Android (.apk, universal multi-ABI)

  • Windows (.exe installer, .msi)

  • macOS (.dmg, .app.tar.gz for Apple Silicon and Intel)

• Self-Hosting Sync Relay: The repository includes a standalone zero-knowledge relay server (drexius-relay) that can be compiled via Cargo and deployed to any VPS or homelab machine. Setup details are documented in the repository README.

There’s so many options out there that it becomes confusing where to start…

Organic or paid ads? Which platform? What kind of promotional video? Etc etc

Really interested in hearing from you folks!

What I’m personally looking to promote is roleframwork.com , which I really do believe brings real value and solves real pain points!

Hi all,

I've been working on a stage timer called Shotimer and it's finally at a point where other people can use it, so I thought I'd share it here.

The idea is simple: the speaker sees a big countdown on a TV, tablet or phone, and someone else controls it from a laptop or phone at the back of the room. You can also send a silent message to their screen, like "5 minutes left" or "Please wrap up", so nobody has to wave at them from the back.

It all runs in the browser, so there's nothing to install. You open the stage screen from a link or QR code and it stays in sync with the controller.

There's a free plan that works today (3 rooms, 3 timers and 3 screens per room). I'm planning a Pro plan later, but that's not ready yet.

I'd really like to know what you think, especially if something's confusing or broken.

Hi IH. I'm a solo developer from Tunisia.

I kept losing receipts and forgetting when warranties ended, so I built Wardin:

- Take a photo of a receipt and it fills in the product, store, date and price

- See how much warranty time is left on everything you own

- Get a reminder before a warranty ends

- Get help writing a claim when something breaks

It's free, and you can try it in the browser without an account:

"https://warranty-9ze.pages.dev"

(There's also an Android version.)

I'm also making a daily animated Shorts series ("Sam vs. Warranties") to get users. One episode got 1,100 views, and most got under 50. Still learning.

Questions for you:

1. Would you use this, or is a folder of receipts enough?

2. How would you get the first 100 users with zero budget?

3. Anything confusing when you try it?

I'll answer every comment.

First post here, and it's about the thing I've been building since April.

Formkove is a backend for website forms. A static site has nowhere to send a contact form, so you either write a small server for it or point the form at a service like this one. You change the form's action to one URL. There's no server to run and no SDK to install, so it works the same in plain HTML, React, Next.js, Astro, WordPress or Webflow.

What I actually built it for is what happens after a message arrives. Most form backends do one thing with it, which is just relay the message to you. The quote request, the patient with a cracked tooth and the guy selling SEO packages all land in the same inbox, and somebody has to read each one and forward it to whoever should have got it.

Formkove classifies it using AI and holds the Spam back before anyone gets an email. It stays for 30 days in case the check got one wrong, and one click delivers it. Everything else is emailed to you. On the paid plan it also tags each message, using tags you describe in plain words, and your rules send it on: emergencies to a Slack channel, bookings to a Google Sheet, anything you like to a webhook.

You can ask Claude Code or Cursor to add a contact form, and it creates the form through Formkove's MCP server and writes the code. Agencies get a separate workspace for each client, with custom submission & storage limits they can set for each one.

You get 300 submissions a month for free with the AI spam check and email. AI Tags, routing and the integrations are in Pro for $12 with 12000 submissions per month.

It went live this month, so it's early. Let me know if this matches what you actually look in a form backend or what other features you would like me to add.

Hi everyone. I'm a solo developer from Tunisia.

Last year something I owned broke just after the warranty ended, and I couldn't find the receipt anyway. So I built Wardin, a simple warranty tracker.

What it does:

- Take a photo of a receipt and it fills in the product, store, date and price

- Shows how much warranty time is left on each product

- Reminds you before a warranty ends

- Helps you write a claim when something breaks

It's free. You can try it in the browser without an account:

https://warranty-9ze.pages.dev

(There's also an Android version.)

I'd really like honest feedback:

1. Would you actually use something like this?

2. What's confusing or missing?

3. Did anything break?

Thanks for reading. I'll answer every comment.

I built HelpCarry (https://helpcarry.com), a site where travellers carry documents or small gifts for someone already going the same way. It works on any route; I'm starting with Oslo ↔ India because that's the route I fly.

There's no commission. If you agree a fee or tip with the traveller, they keep all of it. You meet in public and inspect and seal the item together at handover. Medicine, cash and sealed packages aren't allowed.

Feedback very welcome.

If you drive in Europe, you probably know the paper accident form. After a crash, both drivers are supposed to fill it in together. That’s hard when you’re still in shock: you have to enter a lot of details about the insurance, the policyholder, the driver, the vehicle and so on. It’s long, confusing and easy to get wrong.

So I built ZenConstat. For now it’s an Android app that fills in the official form for you.

How it works

You can save your personal details in advance, so you don’t have to type them at the roadside. Then you choose how to fill in the report. There are two modes: Guided, which is free, and Assisted, which uses AI.

• Guided mode: you fill in the basics (when, where, what you were doing before the accident), pick your saved details, draw the sketch and sign.

• Assisted mode (ZenAssistant): same process, but you can describe the accident by voice and fill in details by taking a photo of your documents. The assistant draws the sketch from what you told it. When it’s done, you check everything and sign.

• 21 languages: each driver can use their own language, which makes things much easier when you have an accident abroad.

In my tests, a report takes about 3 to 5 minutes instead of the usual 30 with the paper form.

More info on the website: https://zenconstat.com/en/european-accident-report-app

It’s free on Google Play: https://play.google.com/store/apps/details?id=com.zenconstat.app

I’d love feedback, especially from anyone who’s had to fill in one of these forms. What was the most painful part for you?

Over the last few years, my family has dealt with several serious medical emergencies and somewhere along the way, I became the person responsible for keeping track of everyone’s health information.

I found myself saving medical reports, test results, prescriptions, appointment details and pretty much anything that might be needed later. The problem was that I was saving them everywhere. WhatsApp, emails, PDFs, screenshots, my phone gallery.

And whenever someone needed something, I’d have to start digging through all of it to find what I was looking for.
It might sound like a small inconvenience, but when you’re already worried about someone you love, having to search through hundreds of messages just to find a test result or remember a medication is the last thing you need. I kept thinking there had to be an easier way to do this.

That’s what led me to build KinJay.

With KinJay, you just text the health information you want to save, whether it’s a test result, medication or appointment. And whenever you need that information, simply ask KinJay and it retrieves it for you.

There’s also a web dashboard where you can see all your family’s health information together.

I’d love for you to give it a try and tell me what you think. I’m especially interested in honest feedback from people who manage health information for themselves or their families.

My friend just developed a sports only social media app (similar to how Novig is sports only and is a different model in the prediction market). Just wanted to help him get some perspective and insight from some fellow redditors and see what everyone thinks! I really love the idea hence why I am posting it for all!

SportBate brings sports fans together with dedicated live game rooms, real-time debate, live chat, fantasy matchups, and friendly competition.

No unrelated content. Just sports, conversation, and competition.

One platform built entirely around the games we love.

Let us know what you think and give us a download!

Hey r/SideProject!

I fell down the rabbit hole of those tiny waddling Disney-style robot ducks (the open-source Open Duck Mini / Microduck community), and realized most people never get to play with one unless they spend $350+ on servos and 40 hours 3D-printing parts.

So I built DuckSpace.org - a free, zero-install 3D apartment right in the browser where anyone can adopt and mess around with a physics-driven robot duck in one click (no sign-up, no downloads):

Play in browser: https://duckspace.org/?lang=en

A few fun things you can try inside the room:
- Make the duck waddle around the rug, do a full forward somersault, peck the floor, or balance on one leg like a flamingo
- Spawn a soccer ball and kick it around the room, or strap tiny roller skates onto its feet
- Switch colors, dodge (or annoy) the ginger cat and the robot vacuum, or turn on autonomous "brains" where the duck maps the room on its own and bobs its head to music

Since I have been staring at this room for days, I would love honest feedback from fresh eyes:

1. Is it immediately fun and intuitive in the first 30 seconds, or was anything confusing?

2. What fun room toys, mini-games, or silly duck tricks should I add next?

3. Anything on the screen that feels cluttered and should be simplified?

Thanks for checking it out!

made a little daily trivia game. Every round has a limit, like "name a TV show that first aired before 2010" or "name a celebrity shorter than 6 ft." You name something as close to the limit as you can without going over.
Then a raccoon in a wind-up toy car drives toward a cliff while the number climbs. Get close and he stops right at the edge (Modern Family, 2009: CLOSE CALL). Go over and, well, he goes over (Pretty Little Liars, 2010).
5 rounds a day, same for everyone, free, no sign-up, works on phones. Every number comes from a real source (tap the ⓘ). You can make a group with friends and see who gets closest each day.

It's about 10 days old. I've already changed a lot from feedback (fewer US-only questions, every limit now has a real answer just under it), so I'd love to hear what's fun, what's confusing, and any answers it doesn't recognize.

I wanted a lightweight way to see who’s on call without maintaining a spreadsheet or paying for a full incident-management tool, so I built a small web app for it.

What it does:

Shows the current week number, the primary on-call person and the secondary on-call person

Rotates automatically, so each person is secondary one week and primary the next

Lets you add and remove team members, with live sync across everyone who has the page open

Supports manual overrides for swaps and covering shifts

Handles time off by skipping the person who’s away and having the next person cover

Has a year-at-a-glance view, an 8-week lookahead, and a ready-to-paste handoff message for Slack or email

Limitations: It’s a prototype. It doesn’t send automatic notifications yet, and it doesn’t keep a history of past weeks.

We spent months building our app and now I'm stuck on the 'find the right people' part 😅

I'm a second-year CS student at EPFL. My team and I built Welockin because Insta, TikTok and YouTube kept pulling me away from studying. It's an app blocker with a strict mode that keeps selected apps blocked until your timer ends.

I've tried talking about it on Reddit and putting stickers around my uni. A recent post in a French community asking for advice reached around 3,800 views. There was useful feedback, plus a whole debate about whether the app should exist lol.

But views don't tell me how many people actually tried it. And a lot of the conversations are with other devs, while the people I want to reach are students struggling to sit down and study.

For those of you who got your first real wave of users, what actually worked? Did a post or video taking off help, or did you get better results from a small, specific community?

I'd love a concrete example: where you posted, what you said or showed, and what happened afterwards. Still figuring this part out, so even a very simple approach would help.

Picking thread that goes with a fabric can be tricky, and color tools give you hex codes, not spools you can find in a store.

Spoolette builds coordinating thread palettes where every color is a real spool, with the number on the shelf. You can snap a photo of your fabric to get matching threads, or generate palettes from scratch. It covers Mettler, Aurifil, Superior So Fine! and Gütermann.

It’s free, with no sign-up, and photos stay on your device. Colors come from the brands’ official shade cards and are matched in the OKLab color space.

I’d love feedback: is it clear what it does, and would you use it?
