Building Unkai Mail · active development

A small studio building native, thoughtful software — starting with a mail client that speaks Nextcloud .

Software, crafted with care.

Featured Project

A mail client, rebuilt for the way you actually work.

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

Software that earns its space on your machine.

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.

01

Open by default.

IMAP, JMAP, CalDAV, CardDAV. We build on standards you can run yourself.

02

Slow on purpose.

Shipping when ready, not when scheduled.

03

In public.

Build logs, decisions, and code — out where you can see them.

04

Sharp details.

The difference is in the parts most people skip.

05

Follow along

We're building in public.
