Show HN: Silo – Every Git branch gets its own localhost

I've been enjoying worktree managers like vibe-kanban and quickly realized I cannot run multiple dev servers, which is a huge no for me. Changing ports for each branch kinda works, but isn't the most efficient way.

Turns out 127.0.0.0/8 gives 16M loopback IPs and they're being wasted, so I decided to put them to work and change IPs instead of ports :3 the usage is quite simple

  silo <whatever>

then each worktree/branch gets a deterministic IP, so you don't have to think about it.

it's not 100% functional (and full of unsafe lol) but wanted to share this first
