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. Across 927 tracked issues and pull requests, the median response latency is 0.0 hours with a mean of 22.8 hours, indicating rapid triage and attention to incoming items. The most prevalent issue labels are Type:Bug with 491 occurrences, followed by Priority:p3-medium with 105 items and Priority:p2-high with 89 items, showing a focus on bug resolution and prioritized work. The core contributor team includes micbar with 737 tracked events, rhafer with 670 events, and ScharfViktor with 394 events, representing the primary maintainers driving the project forward.
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. Notably, GitGenius identifies overlapping contributors with microsoft/vscode, immich-app/immich, and can1357/oh-my-pi, suggesting cross-pollination of ideas and shared community members across related open source projects.
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.
