Tool Open source
Flectar Mail is a native, open-source email, calendar, and contacts client built with Rust. It uses a local-first data path, stores synced mail and calendar data locally for offline use, and connects to Gmail, Outlook, Microsoft 365, IMAP/SMTP, JMAP, CalDAV, and CardDAV services.
Instead of opening email in a WebView, Flectar Mail renders HTML and CSS through Blitz, a Rust renderer from the Dioxus team. It does not execute email scripts and blocks remote images by default; HTML rendering remains experimental, so complex messages may display incorrectly. The client also provides local access to attachments and WebDAV/JMAP files, account signatures, and desktop OpenPGP/MIME signing and encryption through installed GnuPG 2.x.
The project is licensed under the GNU Affero General Public License v3. It provides desktop builds for Linux, Windows, and macOS, plus an experimental Android APK, and can be built from source with Rust. It is currently in development and not yet stable; early releases require users to configure their own OAuth applications for Gmail and Outlook or use IMAP/JMAP accounts.
