Just shipped something on @commonsmade and I’m genuinely hyped. Introducing Starbound Python It’s a small interactive world where you help a robot buddy named Nova rescue lost stars by writing real Python commands. You type a line of code, hit run, and watch the map react in real time. Simple commands, instant feedback, space vibes. I built the whole thing inside the Commons/VibeFi harness. No fighting with deployment, no separate backend setup, just vibe → iterate → ship. The free compute + built-in tools made it feel almost unfair how fast it came together. This is exactly what I think the future of building should feel like: An AI coding environment that doesn’t just help you write code, but actually lets you launch it, share it, and (eventually) earn from it. If Cursor or Claude Code had a built-in accelerator and 24/7 playground for vibecoders… this is the closest thing we’ve got right now. Go play with Nova for a bit. Write a few lines. Light up some stars

SparkGap - an agentic linear algebra experience Hey everyone, I'm building sparkgap.ai , an interactive tutor for linear algebra. You fill in the matrices/vectors, the LLM gives you hints until you get it correct. The hope is that it will get smarter over time from the context of which questions were missed/answered correctly. As you master concepts, the progress ring next to each concept will slowly fill in. Hopefully it should be very difficult to get to full mastery. Feedback and qu

create multiplayer apps that you can play with friends or share with coworkers. Like Slido/Kahoot but you can create your own one with AI. It can build polls, quizzes or games. had this idea for a while, the space isn't new and there is apps like Kahoot that presenters or educators use for polling/quizzes. however the templates are limited, so I decided to ship my own vibe-coding IDE for generating these. you just describe it for example "noise meter: people scream at their phon
