What is it?

OpenCloud is an open source platform for file storage, sharing and collaboration that you can run on your own infrastructure. This repository contains the Go backend services for the OpenCloud server, which the wider project builds on for its web interface and other components.

Users authenticate over OpenID Connect, either against an external identity provider such as Keycloak or against the embedded LibreGraph Connect identity provider. The backend does not use a database; it stores all data directly in the filesystem, with the default root directory at $HOME/.opencloud/.

The repository includes build instructions: running make generate prepares assets such as the web UI and built-in identity provider, and make -C opencloud build produces the opencloud binary. Running opencloud init followed by opencloud server creates a configuration and starts a local test instance.

Key features

  • 01Stores all data directly in the filesystem, with no database required.
  • 02Authenticates users via OpenID Connect with Keycloak or the embedded LibreGraph Connect provider.
  • 03Builds into a single opencloud binary with init and server commands.
  • 04Written in Go and released under Apache 2.0.

Use cases

  • Self-hosting a private file sharing and collaboration service on your own servers.
  • Running a sovereign cloud storage setup that keeps data under your control.
  • Contributing to or studying a Go-based file sync and sharing backend.

Quick start

  1. 1

    Generate the required assets for the web UI and builtin IDP

    make generate
  2. 2

    Compile the opencloud binary

    make -C opencloud build
  3. 3

    Initialize the configuration and start a local test server

    opencloud/bin/opencloud init && opencloud/bin/opencloud server

Things to know

  • Building from source requires a Go toolchain and make, and the README gives no packaged installer for this backend repository.
  • The README points to external documentation for other installation options.
