What I've built with vibe coding
Apps, tools, extensions and games. Some for fun, some for work. Everything here was built with vibe coding: building with AI instead of traditional programming. Click through to see how they look and why I made them.
6 apps are open on GitHub
Tools I run through Claude Code (transcription, image generation, podcast management, PPC and more). Feel free to fork them, use them and build on them. I like giving them to the community.
