Berth
Self-hosted audiobook server in Rust and a Flutter player for Android and iOS. Books live on your own disk, S3 or Google Drive, phones connect with a QR code, listening works offline. Open source (Apache-2.0).
Challenge
Give families and audiobook lovers their own library with no subscriptions and no third-party cloud: books stay where the owner decides, and listening on a phone is easy. Connecting a phone to the server should not require typing addresses, logins or passwords.
Solution
An open-source Rust server in a single Docker container: the library lives in a database, files sit on local disk, any S3-compatible storage or Google Drive, and playback goes through short-lived signed links. A web admin handles uploads and users. The Flutter player connects to the server by scanning a QR code.
Result
The server is on GitHub under Apache-2.0, with a Docker image for amd64 and arm64 (Raspberry Pi, NAS). The app is live on RuStore, with Google Play and App Store in review. The interface is in 10 languages, with light and dark themes.
