What you gain

✓No per-user pricing tied to the Atlassian ecosystem
✓Full ownership of your documentation without Atlassian Cloud dependency
✓No storage limits that force tier upgrades
✓Self-hosted docs with custom access control

What you give up

△No native Jira integration with automatic issue linking
△No Confluence macros for dynamic content (charts, roadmaps, status)
△No space permissions with granular page-level access control
△No Atlassian Analytics for documentation usage metrics

Switching Cost

Confluence's lock-in is the Atlassian ecosystem and macro system. Page content exports as HTML or PDF, but the Jira macros, custom templates, and space hierarchy don't transfer. Teams with simple documentation can migrate in a few days using the built-in export. Teams with complex macro-heavy pages, Jira integrations, and hundreds of spaces should budget 2-3 weeks. The hidden cost is the Jira link: if your team embeds Jira roadmaps, issue lists, and status macros in Confluence pages, every one of those dynamic elements becomes a static snapshot or needs a replacement.

Building Blocks

Confluence is a platform. It bundles multiple capabilities into one subscription. These tools each cover one piece. Teams often assemble 2–3 of them instead of paying for the full suite.
