Arca

Self-hosted durable file storage for people, AI agents, and sandboxes, with versions, shares, and usage tracking.

Servicefreeglobal

Arca is free, self-hosted durable file storage for people, AI agents, and sandboxes, giving every file version history and trash, supporting shares and public links, and letting a sandbox attach to a workspace and sync its results back. It runs on any S3-compatible bucket and Postgres, with identity from any OpenID Connect issuer, and is the same storage service its maker runs in production.
