I've been vibe-prototyping a lot recently and I kept losing track of which terminal was running what. Four or five frontend apps, an API or two, a database running in Docker...

So I made devpanes. It gives you split panes in your terminal for all your dev processes, managed from one config file. Lightweight, zero dependencies except Node.

There are great tools out there already (concurrently, mprocs, tmux), this one just fit how I work. Open source if it's useful to anyone else.
