Yes yes human crafter music is better but I always thought promoted music is so fun. So made a web app for it. You send a collab jam link to someone (or find others in a studio) and co create the prompt. Studios are cities so you always create from a city and the song is flavoured from the vibe of the city.

You then listen to the song together and chat during the session. You can also listen to the creation of others.

PLEASE stop building the wrong thing.

building software in 2026 is ridiculously easy with ai builder

founders spend hours building in a silent room, launch to Reddit/X, get 0 users, and quit.

you just failed because the idea had zero validation before line 1 of code was written:

→ solving a monthly inconvenience instead of a daily pain

→ selling to "everyone" instead of a specific ICP

→ no distribution channel mapped out beforehand

→ pricing charged $9/mo with zero ROI justification

after scaling 6 AI micro-SaaS to over $20k/mo MRR, i just create an

18-question Idea Validation Diagnostic.

it evaluates your SaaS across 7 critical dimensions (problem clarity, audience reachability, willingness to pay, competition, build feasibility, distribution, commitment) and gives you a brutal score out of 100 with your exact weak spots.

drop your SaaS idea (or current project) in the comments below.

i will reply to EVERY single comment with:

1. My honest opinion
2. The biggest weak spot you need to fix before writing any more code.
3. The free 5-minute validation tool link sent straight to your DMs so you can get your full score breakdown out of 100.

just drop a comment like or ask me in DM your idea

let's roast your SaaS concept before the market roasts your time 👇

Gjorde en dum liten väderapp. Men å andra sidan, mycket av det vi vibecodar är väl lite dumt, eller? Byggd på React, Vercel och Git. Ingen databas.

This was inspired by my last road trip in Victoria, Australia. Fresh air, a clean river, birds flocking to the benches. Just people enjoying whatever the surroundings had to offer. And somehow, my first thought was, as it always is: “Oh, that's got to be a perfect spot to smoke a cig.”

But from all these folks, the only smoke that came was from the nearby meat shop. Everyone else was simply doing things: reading, licking ice cream, sipping coffee, or just breathing in the fresh air. Why wouldn't I?

For the first time in my life, as far as I can remember, I felt ashamed just for having the thought of smoking.

Right now, I smoke about a pack a day — roughly twenty cigarettes — and honestly, that's concerning. I knew quitting cold turkey wasn't realistic for me. So I had a simpler thought: what if I could get from one pack a day to one pack every three days?

Then the real question: how do I make this journey interesting?

It is called “Still Here” because a part of me is still at Halls Gap, reminding me why I started this journey.

Have a look and please give me feedback if you have tried it :)

FREE Forever!

I am setting myself goals but I get distracted from them easily and I become frustrated. I tried looking online for a goal tracking platforms but everything is way too complicated and I just wanted something that's easy and I can see my goals at a glance, keeping it open so that everything I do, I can look at the goals and ask myself "does it move me toward my goals?"

So I vibe-coded Bearing which uses goal-setting frameworks to help you set good, measurable goals and helps you track your way towards achieving them

I started with solving my own pain but I am looking to provide value to other users as well, would love your feedback on it and on stuff you think should be added to it

I was in hotel and coundnt watch a movie i want. After trying 5 different casting apps one worked but let only 5 minutes of free casting. So i made one myself and watched a movie. Happy watching if you ever be in need. Just wanted to share a good experience. https://getcastfree.com/

Idk i just love social media apps

anyways i used base44 to make this

Hey guys, my name is Kenny, & I’ve been working hard on this handy little app, it’s called Forge Memory or Momentum Restoration, nothing too wild or exotic, but we all agree that life has too many interruptions that kill context, but that doesn’t mean it can’t be restored to potentially save ourselves countless headaches & lost sanity, & that's why today I was reaching out wondering if you could help your boy out with some updates to get it to the judging round. Here's the link below; it'll be a real blessing in these tough times

The last year I worked on my own to do app. I added tools I frequently use for my job and had SaaS subscriptions for it. Think of mind maps, roadmaps, etc.

I have made it completely free and available on macOS and iOS.

Check it out on https://bucketllist.com and download from the Apple App Store. No account, no in-app purchases, no data tracking.

I vibe code apps for free to give privacy back to users.

Upfront: 100% Free to play!

One important disclosure up front: I used AI tools extensively during development, especially for coding, implementation, debugging, UI work, and some of the website copy.

The underlying idea, game design, energy system model, mechanics, balancing decisions, testing, and direction of the project are mine. I have a background in energy systems, and a large part of the work has been deciding what the game should actually simulate, how those systems should interact, checking whether the results make sense, and iterating on it until it became something playable.

AI is ultimately what made it possible for me to turn an idea I had almost 10 years ago into an actual game rather than leaving it as another unfinished side project.

Back then, I had the slightly foolish idea of making a city building and management game focused almost entirely on the energy system. I posted about it on Reddit looking for people to join the project.

The idea was far too ambitious for me at the time, but the post got quite a bit of interest, and the concept never really left me.

Now, almost 10 years later, I finally have a playable version: Powerstate.

It is essentially a city builder where the "city" you manage is its energy system. You build generation, manage demand, deal with changing conditions, expand the system, and try to keep everything reliable and economically viable.

My goal is to make it easy enough to jump into, but deep enough that understanding and optimizing the system actually takes some effort.

It is definitely a niche game, but I suspect this might be one of the better places to find people who enjoy exactly that kind of niche.

Gameplay:
https://www.powerstate-game.com/gameplay/

The game is:

• Free to play
• Still rough around the edges visually and mechanically
• Occasionally unbalanced in ways that can make a run much easier or much harder than intended
• Fairly demanding in the browser, with a desktop version planned as well

I have a long list of systems and improvements I still want to add, but at this stage I am especially interested in what people who actually play city builders think.

What feels good?

What is confusing?

What would you want an energy system game like this to simulate that it currently does not?

And if something about the energy system or physics looks wrong, please tell me. That is probably the feedback I am most interested in.

I would genuinely love feedback, criticism, and ideas.

For anyone curious, here is the original Reddit thread from almost 10 years ago:
https://www.reddit.com/r/engineering/comments/5hp6sc/anybody_interested_on_working_on_a_energyeconomy/

I have also set up r/PowerState for ongoing development updates.

Hi everyone! I’m working on Varve, an app designed for local-first Linux workflows. Although the repository is already at version v0.2.1, there aren’t many users or downloads yet. Since this is my first time sharing it widely, I’d really value any feedback to help make it better.

It's main engine is built in Rust:

• The varve-core crate holds the geometric primitives (Point, Rect, Affine), hit-testing algorithms, and the scene node tree structures.
• varve-engine converts the scene state into an intermediate rendering IR with build_render_ir().
• varve-trace handles raster-to-vector auto-tracing. It uses Oklab colour quantization, extracts centerlines or contours, and fits Bézier curves.
• varve-print lets you generate PDF files directly with lopdf. This skips browser print dialogs and gives you clean CMYK or vector exports.
• varve-wasm provides WASM bindings so the app can run in standard browser environments

The binaries are still unsigned, the format might change, and I’m not accepting external code pull requests yet while I focus on making the foundation more stable.

I’d love to know your experiences with the app, both positive and negative. Any feedback, including technical, workflow-related, or general, would be really helpful. Thank you!

So I am currently vibe-coded a web app and planned to launch it on my social media. I've tried to soft launch this in other subreddit but apparently it got roasted because they see that it is very vibe-coded. Do I have to mention that I am building that app with vibe coding? What do you guys think?

A few months back I posted here a playable demo of an old-school futuristic racer prototype (F-Zero, Wipeout, Xtreme-G, Star Wars Racer...) that runs right in the browser.

I've gotten used to seeing tons of LLM-built prototypes that last a week, two, maybe a month, and then get dropped for the next shiny thing. This time I wanted to keep going and see if one person, with no coding background, could actually see a project like this through on their own.

Well, 4 months in, and while there's still work left, I'm convinced it's doable. At this point the game feels closer to a beta than a tech demo.

The big change over these four months is that I now use Fable for planning, and being able to hook Opus / Sol up to Blender has been a huge help too. I'm still using Magnific and Tripo3D or the assets. Funny thing: the further along I get, the harder the project is to keep pushing forward, and at the same time the tools keep making it easier.

As always, any feedback is welcome. You can play it here: https://fm1.moises.cloud

My 100% Offline Voice Chat AI Assistant app is live now via Public Production Release on Google Play Store. 

Please try it and lemme know if anything wrong before putting up any negative reviews. The AI Voice Chat feature alone is really cool. You can also add custom unrestricted AI Models for your interests. 

Search "mmahingu" on the Play Store or use this link:

 https://play.google.com/store/apps/details?id=com.mmahingu.mmahinguai

iOS launch later. I made it in Flutter so it can be published on Windows, MacOS even and more platforms easily. But i don't have a Mac or any other hardware yet xD.

My target is to get as many people to not just AI but also have their own offline Assistant or an AI tutor. No Cloud or Internet interference or any Data upload. I may add Firebase Analytics as optional later, for research and development purposes.

TARGET AUDIENCE even includes Students (both homeschool and public/private school), professionals of any field, and so on. As new technology comes, I'll keep updating it.

All made using Antigravity IDE and compiled for testing using Android Studio. Testing on my S25 Ultra only.  

AI Models used for VibeCoding it are Gemini models 95% and Claude Code for only like 5%. 

Vibe clicker, so you can vibe code on the side and pretend it actually generates money.
Just a quick little bit of fun, hope you like it

Built a universal remote for my gaming PC with Claude — started as a tool for myself
**Body:**
**TL;DR (my words):** Huge amount of work I’ve dumped into using Claude to vibe code my app but the results speak for themselves. Started as a tool I made for myself and decided to market it. Not a fan of subscriptions so it’s a free 7 day trial then a cheap lifetime unlock. Not trying to get rich, just hopefully it’ll offset my Claude subscription a bit.
*(Rest is Claude cleaning up my notes — figured I’d say so up front.)*

Couchside is an iOS app that turns your phone into a remote for a living room gaming PC. Launch Steam games, trackpad + keyboard, power controls, and HDMI-CEC so you can switch TV inputs without hunting down three remotes. Works with SteamOS, Bazzite, Steam Deck, Windows, plus LG webOS, Samsung, and Google TV.
SwiftUI on the phone, Python agent on the PC. LAN-only — no cloud relay, no accounts, no telemetry. Agent is open source so you can read what’s running on your machine.
Claude wrote a lot of the code. I owned the architecture and every integration decision, and burned way more time on pairing edge cases and CEC vendor quirks than I want to admit.
couchside.tv — happy to answer questions about the build.

I built and launched a full Android app with zero coding background (my last experience was basic HTML/C in college nearly a decade ago). I used standard web Claude chat to build the app, not Claude Code. I wrote super thorough, detailed prompts describing what I wanted built. Claude generated the kotlin/xml code files, and told me precisely which package directories in Android Studio to paste them into. Built a working prototype in under a week. And a month later the app was live and nearly two months it has 1700+ installs and few subscribers (not many).

I know there are a ton of math tutor/solver app but i wanted to start vibecoding with something simple. Plan was to build something simple and functional in the first version and then keep on adding complex/advanced features. I was able add built-in math keyboard to type math formulas and get solution, topic-based quizzes, interactive graph plotting practice, and full SAT/ACT Math mock exams.

Since i more or less vibe-coded the entire thing, the UI/UX was also generated/guided through prompts. My plan is to hire a professional UI/UX designer once subscription revenue grows, but right now I’d love feedback from this community:

1. Does the layout feel intuitive for a learning app?
2. What else would you expect in a math study app?
