I've relaunched this app!¹ The short version is that it's the gitignore.io equivalent for Homebrew Brewfiles.

There's work to do, but, it's in a reliable and reproducible state.

Previously, it was on a VPS running FreeBSD and was using jails with Nginx and Puma. Now, it's still on a VPS, but it's running Debian and is using containers with Caddy and Puma.

I do not regret using FreeBSD and jails. I learnt from it and would consider using them again, project-dependent.
