European alternatives to Confluence.

Engineering organisations that run Jira for project management have, for a generation, defaulted to Confluence as the team wiki. The product sits inside Atlassian Corporation (incorporated in Australia, listed on NASDAQ as TEAM), and runs on Atlassian's globally distributed cloud infrastructure, where sub-processors fall under CLOUD Act jurisdiction. That ownership and infrastructure profile is exactly what pushes a German procurement team drafting a Schrems II transfer impact assessment, or a European engineering group auditing where its internal documentation actually lives, toward a shortlist of alternatives.

Five European wiki and docs alternatives are verified here against Confluence on the questions that actually decide a procurement shortlist: who legally owns the company, where the data physically sits, which sub-processors touch document content, and whether the platform holds a recognised European compliance framework (ISO 27001, BSI C5, EUCS, SecNumCloud), an editorial check, never a paid placement, re-verified every quarter and sourced to each vendor's public DPA.

For a fast shortlist: Nuclino is the cleanest commercial European wiki for SMB-to-mid-market with German hosting (Germany, Munich, EU-owned, ISO 27001, CLOUD Act exposure: Material), BookStack is the strongest self-hostable open-source option for teams with SRE capacity (UK, open source), and HumHub combines wiki, social intranet, and internal communications in one self-hostable platform (Germany, Munich, EU-owned).

Your documentation doesn't start from zero. Here's what carries over when you move from Confluence to a European wiki:

• A hierarchical page-tree structure (every alternative supports this).
• Rich-text editing with headings, lists, code blocks, embedded media, tables.
• Team collaboration with comments and mentions.
• Page version history and rollback.
• Search across all pages.
• Markdown import and export. Nuclino accepts Confluence XHTML directly; BookStack and HumHub accept Markdown.
• API access for automation.

And here's what stays behind:

• Confluence's native Jira integration. European wikis do not have a direct Jira equivalent; if you migrate, plan to migrate the project-tool layer too (Taiga is the European pick for Jira-style agile).
• Confluence's macro ecosystem. European wikis ship a smaller set of native blocks (page tree, children, callouts, code blocks) but do not have the Confluence Marketplace breadth.
• Confluence Page Templates at full scale. European wikis ship 5–20 templates rather than Confluence's hundreds; most teams use only 3–5 templates anyway.
• Some enterprise-scale permission schemes. European wikis tend to use simpler role-based access; complex per-page ACLs across thousands of pages are not standard.
• Atlassian Intelligence (AI features). European alternatives ship without LLM-based features by default.

Six steps get a Confluence space onto a European wiki without losing its history.

1. Audit your Confluence space structure. Most Confluence instances have 5–20 spaces, but only 3–10 see weekly activity. Use Confluence's space analytics to identify the live set. Plan to migrate only those; archive the rest as PDF or XML export in cold storage.
2. Export each active space. Space Settings → Content Tools → Export lets you generate XML or HTML exports per space. Take XML for the canonical record (preserves page hierarchy and attachments); use HTML for human-readable archives. For very large spaces (5 000+ pages), export in date ranges to keep file sizes manageable.
3. Map Confluence macros to native blocks in the new tool. Common Confluence macros and their European equivalents: Page Tree → native page-tree sidebar, Children Display → native children block, JIRA Issue → embed as HTML link, Excerpt Include → manual extraction. Build the mapping table before starting the page import.
4. Import pages in cohort order. Nuclino accepts Confluence XHTML exports directly via its bulk import; BookStack and HumHub accept Markdown after a Pandoc conversion step. Start with template/landing pages, then migrate active pages by recency.
5. Migrate permissions as a documented model, not as an automated copy. Confluence permission schemes (space permissions × page restrictions × user/group inheritance) cannot be exported. Document your current permission model on paper, then re-create as simpler role-based permissions in the new tool. Most teams find that 70–80% of historical Confluence permissions were redundant.
6. Keep Confluence paused, not cancelled, for 90 days. A wiki always turns out to be more entangled than the audit in step 1 suggested: pause first, do not cancel immediately. You will find a Jira issue linking to a Confluence page, a Slack share-to-Confluence integration, or a calendar invite with a Confluence link in the body. Pause Confluence and keep paying the lowest tier for 90 days.
