Collabora Online
Verified working Aug 6, 2026
Self-hostable office editing for teams that need data control.
Collabora Online is an open-source office suite for editing documents, spreadsheets, presentations, and drawings in the browser. It is built for organizations that want collaborative document editing inside their own infrastructure, storage platform, LMS, portal, or SaaS product, with desktop and mobile options available through Collabora Office.
Why it stands out
- Designed for organizations that want office collaboration without handing documents to a large public-cloud provider
- Open-source codebase with a commercial support and SLA path for enterprise deployments
- Built specifically to be embedded into storage, education, productivity, portal, and SaaS products
- Broad partner ecosystem, with the site citing 200+ partners integrating Collabora Online globally
- Combines online collaboration with related desktop and mobile office apps rather than being browser-only
Good to know
- Production use generally requires either your own infrastructure or a hosting/integration partner.
- Pricing is not fully transparent from the homepage; users are directed to request a quote.
- Advanced integrations, scaling, and Kubernetes-based deployments are likely to require technical administration.
- The free CODE edition is positioned as a development/testing option rather than the main supported production offering.
