What is it?

OxiCloud is a self-hosted cloud suite that bundles file storage, a web interface, calendars and contacts into one server. It is aimed at self-hosters, home labs and small teams who want the core features of a cloud suite without the resource cost of a traditional PHP stack.

The server is written in Rust on Axum and uses PostgreSQL as its database. It exposes standard WebDAV, CalDAV and CardDAV endpoints, so desktop file managers, Thunderbird, Apple Calendar and DAVx5 on Android can connect without custom sync software. The web UI covers uploads, previews, thumbnails, sharing, trash, search and favorites, and the project supports OIDC/SSO, quotas and admin/user roles.

Deployment is available through Docker Compose, prebuilt binaries, a Helm chart and a Nix module, with settings driven by environment variables. WOPI integration allows editing documents with Collabora or OnlyOffice.
