Product overview

Bebra Sync is a file synchronization and collaboration platform designed for teams that treat their data as an asset. Below is a complete tour of what ships with every workspace.

Synchronization engine

Our sync engine splits files into content-defined chunks and transfers only what changed. Renames, moves and partial edits are detected automatically, so a 10 MB edit to a 4 GB container costs 10 MB of bandwidth — not 4 GB.

• Block-level delta sync with content-defined chunking
• LAN peer sync: devices on the same network exchange blocks directly
• Selective sync and on-demand placeholders to save disk space
• Automatic conflict resolution with side-by-side comparison

Security model

Encryption happens client-side using XChaCha20-Poly1305. Workspace keys are wrapped per-device and never transmitted in plaintext. Server operators — including us — cannot read file content or filenames.

Collaboration

• Shared workspaces with role-based access (owner, editor, commenter, viewer)
• Share links with expiry dates, passwords and download caps
• File requests: collect files from people without accounts
• Comments and @mentions on any file, synced to email

Administration

• SAML 2.0 SSO (Okta, Entra ID, Google Workspace, JumpCloud)
• SCIM provisioning and deprovisioning
• Device inventory with remote wipe
• Immutable audit log with CSV/JSON export and SIEM webhook

Platforms

Native clients for macOS 13+, Windows 10/11 and Linux (deb/rpm/AppImage). Mobile apps for iOS and Android with camera upload. Full-featured web client for everything else.
