Nothing to host, and the prompt manager can even follow you onto local apps on localhost.

Only building from source needs Bun and Node tooling.

The seasonal visual effects are purely cosmetic full-screen overlays that don't block page interaction.

A useful side effect: when a Gemini issue made historical chats inaccessible, Voyager users still saw their saved conversations in folders.

Voyager proved its worth when a Gemini issue cut off historical chats while Voyager users kept theirs in folders.
