Pebble

Pebble is a desktop mail client built with Rust, Tauri, and React. It keeps mail data, the search index, attachments, rules, and application settings on your device by default.

The app is designed around a few practical ideas:

- Your mailbox should stay readable, fast, and quiet.

- Email workflows should be local-first instead of cloud-dashboard-first.

- Privacy controls should be explicit, visible, and easy to override per message.

- Search, snooze, rules, and a Kanban board should work together instead of living in separate tools.

Pebble currently supports Gmail, IMAP, and experimental Outlook accounts.
