The Community edition is fully featured — no artificial limits.

🔒

End-to-end encrypted

AES-256-GCM encryption in the browser via the Web Crypto API. The server never sees your files or keys.

🫥

Zero-knowledge

The encryption key lives only in the URL fragment — it is never sent to the server, ever.

📁

Files & text

Transfer single files, multiple files (auto-zipped), or secret text notes and passwords.

🔑

Password protection

Add an optional password on any transfer. Secure passwords are generated automatically.

⏱️

Expiration & download limits

Set a time-to-live and a maximum number of downloads per transfer.

Instant revocation

Revoke any transfer at any time from your dashboard.

🛡️

Admin dashboard

Full visibility over all transfers: revoke, delete, storage metrics, deletion audit log.

⚙️

Instance settings

Enforce password on all sends, require authentication to download, configure cleanup schedules.

🏢

Enterprise authentication

Keycloak out of the box — OAuth2, OIDC, SSO, LDAP/Active Directory, MFA.

☁️

Flexible storage

Local filesystem or any S3-compatible provider (AWS, MinIO, Scaleway, OVHcloud…).

🎨

Custom branding

Set your own colour, logo, and app name — applied to both the app and the Keycloak login page.

🌐

Multi-language UI

English and French included. Additional languages can be added via translation files.

🌙

Dark mode

System-aware dark theme, togglable per user.

📱

QR code sharing

Every transfer generates a QR code for easy cross-device sharing.

🐳

Docker-native

Full stack in a single docker compose up. Images published to GHCR.
