Stellar - Starship prompt theme manager

I've been using Starship for a while and noticed there's no centralized way to discover/manage themes - you just copy-paste configs from wherever you find them. I also switched my prompt from time to time, depending on the color of my wallpaper, and wanted a better way to do this than manually copying config files. So I built Stellar: a theme hub + CLI tool. Key features: - Central hub for browsing themes - Preview themes before applying (spawns test terminal) - Version management (stellar apply theme@1.2) - Auto-backs up your existing config on first use - NixOS flake included Technical details: - CLI in Go (single binary, ~5MB) - Web hub: Next.js + Supabase - Stores themes locally in ~/.config/stellar, symlinks starship.toml to selected config - Simple install & self-update built in I'd love to hear some feedback :)
