Open Source Confluence Alternative
Escape vendor lock-in. Reclaim your data. Cut costs by 70%. Docmost is the enterprise-grade wiki for teams tired of Atlassian's pricing and Cloud migration ultimatums.
Confluence is getting expensive
Atlassian killed Server in February 2024. Cloud forces data residency complexity. Data Center runs $27,000 to $89,000 per year—before your infrastructure costs.
And prices keep rising. Atlassian raised rates 15–25% in February 2026. Marketplace apps cost extra. Access control costs extra. Automation overages cost extra.
For a 50-person team using Confluence Cloud with marketplace apps and access controls, real spend lands at $21.22 per person per month. Nearly double the sticker price.
Open source wikis offer a way out. The question is: which one actually fits your team?
Why Docmost Wins Over Confluence Cloud
Confluence pricing as of Feb 2026. Real TCO includes Premium plan + marketplace apps + Atlassian Access. Docmost Business tier minimum: 10 seats.
Why Docmost Is the Best Open Source Confluence Alternative
Real-time collaboration, GDPR compliance, and escape from Confluence's cost spiral.
Real-Time Collaboration
Live cursors, instant sync, multi-user editing—everyone sees changes as they happen. BookStack uses page-level locking; only one person edits at a time. Outline requires external dependencies. Docmost gives you true simultaneous editing, no conflicts, no refreshes.
Compliance-Ready, Not Blocked
GDPR, ITAR, FedRAMP, air-gapped deployment: all built in, not afterthought add-ons. No data residency maneuvering. No vendor approval delays. Trusted by Airbus, Australian Government, and German Red Cross for a reason.
Enterprise Power, Startup Pricing
Free for small teams. $6 per seat for Business tier. No marketplace tax. No access-control surcharge. No automation overages. Predictable spend that grows with your team, not against it. Compared to Confluence's $21.22 real cost per person, you save 70%.

What you get with each
BookStack wins on simplicity and lightness. If you just need a basic wiki and don't mind one person editing at a time, BookStack runs on a $5/month LAMP server with zero complexity. Great for small teams.
XWiki excels in structured data and extensibility. It's the pick for large enterprises with complex hierarchies, custom workflows, and teams who can handle Java infrastructure. Older, proven, enterprise-heavy.
Wiki.js appeals to developer teams who want Git-backed version control and a modern Node.js stack. Good for documentation that lives in your repository.
Outline is clean, collaborative, and modern, but requires Redis, PostgreSQL, and more infrastructure work. Slack-first design is either perfect for you or misses the mark.
Docmost is the sweet spot: real-time collaboration right out of the box, compliance features built in (ITAR, FedRAMP, GDPR), Confluence importer included, databases and Kanban for power users, and a modern stack that's easy to deploy. Trusted by Airbus, Australian Government, and German Red Cross. If you're leaving Confluence, Docmost is the path of least resistance.

Docmost offers genuine real-time multi-user editing, built-in AI assistant, databases, and Kanban boards. Pick BookStack if you just need a lightweight wiki. Pick Docmost if your team collaborates constantly and needs enterprise features.
