OpenCloud

OpenCloud provides a self‑hostable server for sharing files and collaborating on them. It runs as a Go‑based backend that stores all data directly in the filesystem, eliminating the need for a separate database. Users authenticate through OpenID Connect, either via an external identity provider such as Keycloak or the built‑in LibreGraph Connect service.

The platform is released under the Apache 2.0 license and is offered without subscription or tiered pricing, making it suitable for individuals, teams, or organizations that require a free, open‑source solution they can run on their own infrastructure. Its stable maturity level indicates that core functionality is production‑ready.

Developers can contribute by reporting issues, requesting features, improving documentation, or extending the codebase. Build instructions are provided for compiling the binary and launching a local test instance, and further setup guidance is available in the online documentation.
