The Take

It pairs a searchable Next.js hub with a single-file Go CLI that symlinks versioned starship.toml files so you can preview themes in a real terminal and swap or rollback with one command. Useful details pop up everywhere: preview spawns a test window, apply supports specific versions and updates, and themes are cached locally. Downsides: publishing is still a manual upload flow and Windows support is notably absent, which curbs adoption.

Post Description

I built this because discovering good Starship themes usually meant digging through random dotfiles repos on GitHub. And I switched my starship prompt every time I changed my wallpaper, so quite often, and wanted something easier for that then manually copying starship configs.

Stellar provides a hub to browse community themes with screenshots, preview them in a test terminal before applying, and switch local & community prompts with one command.

Tech: Go CLI (single binary) + Next.js hub + Supabase. Themes stored locally with starship.toml symlinked to them.

Just launched v1.0.0. Happy to answer questions, and I'd love some feedback :) Also, feel free to upload your own starship prompt :)
