Every package Cozy Stack depends on, ranked by repo health score.
Cozy Stack is the open-source backend server powering the Cozy platform, a personal cloud environment that puts you in control of your own data. Developed by Twake Workplace and distributed under AGPLv3, it enables individuals and small teams to self-host a unified workspace where files, contacts, notes, banking data, and productivity apps coexist in a single private instance — free from profiling, vendor lock-in, or cloud dependency.
At its core, the stack is a single Go binary that speaks REST, manages CouchDB document storage, runs sandboxed jobs (called konnectors) for third-party data importation, and synchronizes data in real time across devices via PouchDB replication and WebSockets. Every user gets their own subdomain-isolated instance, and the admin API makes it straightforward to provision, backup, and migrate those instances programmatically.
Cozy Stack also ships with built-in integrations for collaborative document editing via OnlyOffice, a Bitwarden-compatible password vault API, NextCloud-compatible file sharing, OpenID Connect for federated login, and even a RAG-backed AI chat endpoint. This breadth makes it unusual among self-hosted tools — it is genuinely an application platform, not just a file server.
Deployment is straightforward for technically comfortable users: a single binary, a CouchDB 3 instance, a reverse proxy, and a SMTP relay. Docker images and Debian packages are provided. The project has over a decade of active development with more than 12,000 commits, 130+ releases, and a cadence of roughly two releases per month.
