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.
Highlights
Local-first privacy
- Local SQLite database for messages, folders, labels, rules, and settings.
- Local Tantivy full-text index for fast search.
- Attachments are stored on disk under the app data directory.
- OAuth tokens and credentials are encrypted with a per-device key.
- No telemetry.
- Network requests are limited to features you configure: mail sync, translation, and optional WebDAV settings backup.
Mail workflow
- Unified inbox across multiple accounts.
- Gmail, IMAP, and experimental Outlook support.
- Threaded and message-list views.
- Archive, delete, star, mark read, batch actions, and restore flows.
- Snooze messages and bring them back later.
- Full-text search and advanced filters.
- Rules engine for automatic organization.
