Tools
I vibe-coded these tools for myself and share them here in case they are useful to others too. If you need something similar, feel free to use any of them.
All of these tools run fully locally in your browser. No functional data is sent to a server.

Support this project
I build and maintain this tool in my spare time. It is free to use, and I'd like to keep it that way.
If it saved you time, helped you at work, or you simply want to support future improvements, a small donation goes a long way.
Your support helps cover hosting, domain costs, maintenance, bug fixes, new features, and the occasional vibe coding tokens 😉.
