OpenCloud is an open source platform for file management, sharing, and collaboration, written primarily in Go and released under the Apache 2.0 license. The repository at opencloud-eu/opencloud contains the main server backend codebase, serving as the core implementation of the OpenCloud system. The project emphasizes sovereignty and simplicity in cloud storage and collaboration, with the official homepage at opencloud.eu providing additional information about the platform and installation procedures.
The backend architecture relies on OpenID Connect for user authentication, supporting both external identity providers like Keycloak and an embedded LibreGraph Connect identity provider. A distinctive design choice is that the OpenCloud backend does not use a traditional database; instead, it stores all data in the filesystem, with the default root directory located at $HOME/.opencloud/. This filesystem-based approach simplifies deployment and data management while maintaining full control over data storage.
According to GitGenius activity tracking, the repository demonstrates active maintenance and community engagement.
The repository is classified across multiple technology domains including cloud-native, platform, application management, service management, Kubernetes, DevOps, serverless, microservices, edge computing, and multi-cloud capabilities. This broad classification reflects the platform's design to operate across diverse infrastructure environments.
The project actively welcomes contributions in multiple forms, including bug reporting, feature requests, documentation writing, code contributions, test extensions, and code review. The repository includes comprehensive contribution guidelines and development documentation at docs.opencloud.eu/ to help new contributors get started. The build process involves generating assets for components like the web UI and built-in identity provider, followed by compilation of the opencloud binary. A two-step command enables developers to quickly create a server configuration and launch a local test instance for development purposes. The project maintains an active community presence through Matrix chat at #opencloud:matrix.org, providing real-time support and discussion channels for contributors and users.
