Tesseract
The native desktop Matrix client you always wanted.
↑ A live simulator — switch rooms, send a message, click the room header for info, right-click your account, toggle the theme. Not connected to any real server.
Tesseract is a full-featured desktop Matrix client for Linux, Windows and macOS, built on the Matrix Rust SDK. The networking core is Rust; each platform gets a genuinely native UI — Win32 on Windows, AppKit on macOS, and Qt6 or GTK4 on Linux — so it looks and feels right everywhere, no web view in sight.
Win32, macOS AppKit, and Linux Qt6 & GTK4 — one shared C++ toolkit, native everywhere.
