Safebucket

Open-source file sharing platform where files bypass the server and transfer directly to S

Visit Safebucket

Safebucket is an open-source file sharing platform that routes uploads and downloads directly to S3-compatible storage through presigned URLs, so file data does not pass through the application server. It manages metadata, access control, and audit logging while you supply your own identity provider, storage, and infrastructure.

Sharing is organized around buckets with nested folders, role-based permissions (owner, contributor, viewer), and platform roles (admin, user, guest). Features include in-browser previews, bulk ZIP downloads, public quick share links with expiration, password protection, view limits, and reverse shares that accept uploads from external users, plus file expiration, trash retention, email invitations, activity tracking, and notifications. Authentication supports OIDC SSO, LDAP/Active Directory, local accounts, and TOTP multi-factor authentication. The stack includes a Go REST API, React web interface, PostgreSQL or SQLite, and swappable components for storage (AWS S3, GCS, MinIO, RustFS), events (NATS JetStream, AWS SQS, GCP Pub/Sub), cache (Redis, Valkey), and logging (Loki or filesystem).

It is aimed at teams that want self-hosted file sharing integrated with existing identity and storage systems. Deployment templates cover Docker Compose (full and lite), running from source, and AWS via Terraform.
