Vithos vs Mimestream
Same Mac-native Gmail bet. Different product: polish versus keyboard-first speed.
Mimestream is the most considered Gmail client on macOS — native chrome, labels that behave like Gmail, mail that stays on your disk. Plenty of people who want a keyboard-first Gmail client for Mac land there first.
Vithos starts from the same Mac + Gmail constraint and optimizes for a different job: every action on a key and in the palette, search that answers as you type from a local index, fully offline, and a public API + MCP server so Cursor and Claude can touch your inbox with scoped keys. Mimestream is prettier. Vithos is built to be driven without the mouse.
Side by side
Why people switch
Keyboard as the product
Mimestream feels like a great Mac app. Vithos feels like a keyboard instrument: archive, remind, switch accounts, and search without leaving home row.
Local index, no round-trip
Vithos indexes mail on your Mac and answers before you finish typing — on a plane or in a tunnel — because the answer is already there.
Scriptable when you need it
Want Cursor or Claude on your Gmail? Vithos ships a documented API and MCP server with scoped, revocable keys. Mimestream does not.
If you want the prettiest native Gmail client, Mimestream earns it. If you want a keyboard-first Gmail client for Mac you can drive with chords and scripts, that is Vithos.
