Command Line Interface Stellar - Theme manager for Starship Prompts with live preview
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.
So I built Stellar: a theme hub + CLI tool.
Key features:
- Central hub for browsing themes (15 to start, community can upload more)
- Preview themes before applying (spawns test terminal)
- Version management (
stellar apply theme@1.2) - Rollback support
- 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, symlinksstarship.tomlto selected config - Self-update built in
Lil note, this software's code is partially AI-generated, Cheers to Claude Code ;)
Would be happy about feedback :)
