Ranked by feature parity + compliance score. Migration friction is weighted higher than feature breadth.
UK solo-dev MIT-licensed self-hosted wiki + documentation platform (Dan Brown, 2015); no SaaS, no vendor counterparty risk.
AGPLv3 open-source Node.js wiki by Nicolas Giard (Canada, 2016); 100M+ downloads; multiple DB backends; 40+ languages; self-host only.
US-incorporated open-source-style wiki (Outline, NYC) under BSL licence; self-hostable for EU sovereignty, but hosted cloud is US.
For every product we read the public DPA, sub-processors document, hosting region declaration, and corporate ownership records. Each is timestamped. Compliance score is editorial, re-verified quarterly. We never accept self-attestation.
