What is OpenCloud?

OpenCloud is a self-hosted platform for file management, sharing and collaboration. This repository holds the backend: a set of Go services compiled into one opencloud binary that also bundles the web interface assets and an identity provider. It needs no database; all data lives in the filesystem, under $HOME/.opencloud by default. Users authenticate with OpenID Connect, either through an external provider such as Keycloak or through the embedded LibreGraph Connect. The interface is available in 20 languages counted from translation files.

Good fit if

  • You want a file sync and share server for a team or organization that runs without a separate database.
  • You already operate an OpenID Connect provider and want file access tied to it.
  • You prefer a permissive license for a platform you may extend or embed.

Look elsewhere if

  • You would rather run an AGPL-licensed sync and share suite: Nextcloud or ownCloud.
  • You only want to share one folder for a while from your own machine: miniserve.
  • You want peer-to-peer syncing between devices with no server: Syncthing.

Before you adopt it

OpenCloud uses the Apache license, which permits commercial use and modification with few conditions, and the repository has no paid parts. Contributions require a contributor license agreement. OpenCloud GmbH stands behind the project, and work is spread across twelve authors in the last 90 days with frequent commits. The repository dates from January 2025, so the codebase is young. Docker images and Linux and macOS builds exist; installation guides live in a separate repository rather than here.
