Bichon

Bichon is a lightweight, high-performance, self-hosted email archiver built in Rust. It synchronizes emails from IMAP servers, indexes them for full-text search, and provides a clean WebUI and REST API for access.

Bichon requires no external database and runs as a single binary — making it easy to deploy and maintain. It supports multiple accounts, OAuth2, SOCKS5 proxy, scheduled sync, bulk import (EML/MBOX/PST), and multi-user RBAC.

As the sole maintainer, I develop and support Bichon in my personal time. With 1.8k GitHub stars and 327k+ Docker pulls, the project has grown well beyond a personal tool and is actively used by individuals and teams worldwide — including a real-world deployment archiving 1.15 million emails across 28 accounts (800 GB original data, compressed to 421 GB on disk).
