Native, not a webview.
We build with Rust and other native tooling. Apps that boot fast, sip battery, and respect the system they run on.
A small studio building native, thoughtful software — starting with a mail client that speaks Nextcloud .
Featured Project
Unkai Mail treats Nextcloud as a first-class citizen of the inbox — Talk rooms from a thread, files from your cloud, contacts and calendar in lockstep. Native, fast, written in Rust.
How we build
We build with Rust and other native tooling. Apps that boot fast, sip battery, and respect the system they run on.
IMAP, JMAP, CalDAV, CardDAV. We build on standards you can run yourself.
Shipping when ready, not when scheduled.
Build logs, decisions, and code — out where you can see them.
The difference is in the parts most people skip.
