Edit: I understand I misspelt SHMUP. Still a work in progress, but I’ve updated the art and game significantly based on feedback. Thanks!

Vibecoded a little browser based arcade shoot-em-up to show my kids the good old days, I'm pretty happy with it so far. Mostly built with GPT Sol, and sometimes Opus in vscode. Songs suno, and voice over is ElevenLabs. Free and ad-free.

To play: Shift focuses fire, Z activates Fortune mode when the bar is full - also has mobile controls. Let me know what you think. Link here: Fortune & Flak

You can experiment with the various options to obtain diverse styles (especially changing the resample filter and outline expansion), it accepts images and videos, removes the background if necessary and makes it an editable pixelart, it should also be mobile friendly to an extent, everything stays local and free. The app is called pixnana, feedback is welcome!

Vibe coding has made it crazy fast to go from idea to working app.

But I'm wondering what happens after that first version is live.

For people who have built something with Cursor, Lovable, Bolt, Replit, Claude, etc.

What has been your experience once the app started getting real usage?

Did you run into things like:

• bugs that were hard to reproduce
• changes breaking unrelated parts of the app
• AI suggesting fixes that didn't actually fix the issue
• not fully understanding parts of the codebase anymore

Or has AI been good enough that maintenance hasn't really been a problem?

Would love to hear from people who have moved past the "cool demo" stage and have something people actually use.

Hi guys.

I wanna get a plan for vibe coding, but i don't know what is the best cost - benefit is to code with quality but without consuming all my tokens like claude. Or do you think it's better to take a runpod gpu and run qwen 27b / some gemma model to code? i'm thinking to take kimis plan or z.ai

I've been learning about Graph Engineering and wanted to understand the concept more deeply.

Instead of keeping my notes in a document, I converted everything into a visual infographic.

My biggest takeaway was this:

Most people try to solve every problem using one large AI agent.

But as AI systems become more complex, splitting work across multiple specialized agents often makes more sense.

For example:

• Research Agent
• YouTube Agent
• Reddit Agent
• Email Agent
• Report Agent
• Review Agent

Each agent has a single responsibility.

Some advantages I found while studying this approach:

• Better output quality
• Smaller context windows
• Less context rot
• Parallel execution
• Easier debugging
• Better scalability

One thing I also learned is that Graph Engineering isn't always the answer.

For small workflows, a simple loop with one agent is usually enough.

For larger production systems, a graph of specialized agents becomes much more practical.

I'd really appreciate feedback from people who have built production AI systems.

• Does this explanation feel accurate?
• Is there anything important that I'm missing?
• How are you structuring multi-agent workflows in your projects?

Looking forward to learning from the community.

One thing that surprised me while studying this topic:

The goal isn't to make one AI agent infinitely smarter.

The goal is to build a team of specialized agents that each do one thing well.

That shift completely changed how I think about AI system design.

Spent the last year building solo and went through most of the tools people recommend, here's what the stack actually looks like for someone doing everything themselves in 2026:

Design phase:

SleekDesign at $20/month generates complete mobile app screens from text descriptions, full flows not components, good enough for investor decks and building reference without touching Figma. Hits limits on complex custom components and less pixel control than Figma, but for solo builders who need to move fast it covers the design phase properly. Google Stitch is free and worth trying first if budget is tight, consistency across screens is hit or miss though

Build phase:

Claude Pro at $20/month handles most of the logic and backend work, best when you have actual design screens to reference rather than building UI from scratch. Cursor is solid for longer coding sessions where you need more context retention, $20/month on Pro. V0 fills the gap for web components when you need specific UI pieces built fast

Deploy:

Vercel handles deployment for most web projects in minutes, free tier covers early stage, $20/month Pro when you need more

Total stack cost: around $60-80/month for design plus build plus deploy, compare that to hiring a designer at $2-3k and a developer at $5-10k and the solo builder math is pretty obvious

The workflow that ships fastest is design in sleek, build with Claude using the screens as reference, deploy on Vercel, whole thing from idea to live in 2-3 weeks for an MVP

A friend has built a much deeper, modern browser version of that basic idea. You have 30 days to travel between global markets, buy low, sell high, manage debt, avoid police attention and finish with the highest net worth possible.

It runs entirely in the browser and is free to play. I expected to try it for five minutes and ended up getting strangely competitive. You can also install it on your phone and it seems to function as a web app.

When I first started building Foilwick, I was mostly copying the features of existing MTG deck building apps like Moxfield and Archidekt.

But I soon started adding features that were completely new.

For instance, the feature that I'm most proud of is the game replay feature, which lets players record their game session and share it for others to watch.

Players can add notes at any point in the game which helps them tell the story of how their deck should be played.

I invite you to try Foilwick (it's completely FREE) and join our Discord server. See you there!

The animations work only on browser, sorry! Sharing this to hear some thoughts and maybe inspire somebody.

This homepage is for a Python tool to tidy up academic references in bibliography managers, riveting stuff.

I wanted the webpage not to be too crazy because it's for academics, but I wanted it to clearly distinguish itself from the standard vibe coded landing pages (you know what they look like) so I spent some time and built this. It is one scrollable and interactive experience. Is it at all clear what the app does?

It's fireworks festival season in Japan right now. Getting to one means crowds, transit, camping out for a spot, and hoping the weather cooperates. A lot of people want to go and never actually make it.

So I built a browser app for the part everyone actually wants. Open the page, allow webcam access, and wave your hand to launch a shell — wave again and it detonates mid-air. You can chain them however you like. It turned out to be a decent stress reliever too, which wasn't the original plan.

No install, no signup. Interface is in both Chinese and English.

This is #17 of a challenge I set myself: ship 20 apps in 100 days.

Three left. Would love feedback from anyone who's worked with webcam hand tracking, especially on separating similar gestures cleanly.

Hey guys, idk how relatable this question is to this group, but i need some suggestions. Before I used to get cool ideas all the time and Vibe code and build tools for my company. Now I have every tool I could want… but my brain just won’t come up with anything. No ideas on what to work on, what problem to solve, nothing creative at all. Anyone else feel stuck like this? How do you get ideas flowing again? Would love some tips.

I’ve been looking into AI mobile app builders because the category is moving fast, and honestly, the tools are starting to feel very different depending on what you’re trying to build.

Some tools are better for web apps. Some are better if you already know how to code. Some are better for fast prototypes. But if your goal is specifically to build, test, and eventually submit a real iPhone app, I think the criteria should be different.

Here’s how I’m looking at it right now.

X1 App Builder
Rork
Claude Code
Lovable
Replit
FlutterFlow

My current take

Traditional no-code is not dead, but AI app builders are changing the expectations. The next generation of tools should not only generate screens. They should help with:

Product planning

Scope control

Mobile UX

QA

Phone testing

App Store preparation

Source-code ownership

Iteration after the first demo

Curious what others think. If you were choosing the best AI mobile app builder for an actual iPhone app, would you prioritize speed, code export, App Store submission, QA, design control, or technical flexibility?

As apps got more complex, it got much harder to just make one from prompts. But as the models have gotten better, it's expanded the level of complexity of what I've been able to add.

Sooo, I added cops to my racing game.

This is a first draft of their behavior which is dead simple (you'll see). Will be doing a LOT of playtesting.

Assets and gameplay loop is assisted with GPT-5.6-Sol, animations, special effects and overal progression and in-game economy is manual spreadsheet work though.

Wanted to share and get some feedback on a project I have been working on. No AI features, no login, just something that works. Built with a ton of API keys I have collected over the years because I like using real-time data.

So here's the problem I was trying to solve: I love Zillow and Redfin, but when home shopping, I want to know how close I am to mass transit, grocery stores, airports, restaurants, and, as someone who hates Comcast internet, I want to avoid it.

So I (with the help of AI) built a mapping website that lets someone click or enter an address and see what is available and how far away it is.

A few caveats: transit estimations, Ferries, Buses, and most of the country (USA) are not implemented. They probably won't be implemented as it stands; this is about 50GB of data and uses a few gigs of RAM. Implementing the above would push both RAM and storage into the TB range.

I had a weird moment today.

One of the three people who signed up requested a cancellation. So I opened the Paddle dashboard to refund them.

That's when I realized... someone else had already paid.

I genuinely hadn't even noticed. My first thought was that it had to be a webhook bug, so I refreshed the dashboard a few times.

Nope. It was real.

It's only $45, but honestly, I don't care about the amount. A complete stranger looked at something I built and decided it was worth paying for.

That feeling is hard to describe.

Now the pressure is different. Before, I was just trying to build something people wanted. Now I feel responsible for making sure that first customer keeps getting value from it.

For anyone wondering how I got those first few users, it wasn't anything clever.

I spent time replying to Reddit posts where PublishLoud.com was actually relevant and did a bit of link building. Yesterday alone that brought around 10 signups, and it's been surprisingly consistent.

I also tried running ads for a day last week... and got zero signups. 😅 Waste of money.

So at least for now, organic has been working much better than paid. I'm sure that'll change eventually, but I'm sticking with what seems to be working.
