Assessment notes
Wiki.js is an AGPLv3 open-source Node.js wiki created by Nicolas Giard (Montréal, Canada, senior software developer at IETF Administration LLC) in 2016 and led primarily by him through community contributions. 100M+ downloads, 28k+ GitHub stars, 40+ UI languages, no managed cloud, pure self-host on customer-chosen infrastructure. Canada holds EU adequacy decision under Art. 45 GDPR. When deployed on EU infrastructure (Hetzner, OVHcloud, Scaleway, IONOS, STACKIT) there is no CLOUD Act exposure, no vendor counterparty, no commercial entity, and no cap-table risk.

About Wiki.js
Wiki.js is an AGPLv3-licensed open-source wiki and documentation platform created by Nicolas Giard, a Montréal-based senior software developer (currently at IETF Administration LLC), and first released in 2016. The codebase is written in JavaScript on Node.js with a modern UI, fast performance, and a modular architecture that supports multiple database backends (PostgreSQL, MySQL, MariaDB, MS SQL Server, SQLite), multiple storage backends (Git sync, AWS S3, Azure Blob, Google Cloud Storage, local/network), multiple authentication options (local, LDAP, SAML, Azure AD, social OAuth), and multiple search providers (built-in DB search, Algolia, Azure Search, Elasticsearch). The project reports more than 100M downloads and 28k+ GitHub stars; supported by sponsors including DigitalOcean, GitHub, Cloudflare, and Netlify.
For procurement-grade EU buyers Wiki.js is structurally clean for the self-host path. The licence is full AGPLv3 with the standard copyleft requirements (any network-distributed modification must publish source under AGPL) so it suits in-house documentation use cases without complications. Self-host on EU infrastructure (Hetzner, OVHcloud, Scaleway, IONOS, STACKIT, T Cloud Public, or any other EU-incorporated host) delivers no CLOUD Act exposure and no vendor counterparty. The maintainer is Canadian; Canada holds an EU adequacy decision under Art. 45 GDPR so cross-border transfers between EU and Canada need no SCCs, but for self-host deployments the maintainer-jurisdiction is irrelevant since the customer controls all data flows.
Pricing is free for the open-source codebase; commercial support is offered via the maintainer + community. Best fit: developer teams and engineering organisations building internal documentation, EU SMBs and public-sector buyers wanting a Node.js modern stack alternative to MediaWiki / DokuWiki, customers who need Git-versioned content with full self-host control, and any organisation that prefers Node.js to PHP (vs BookStack which is PHP/Laravel-based).
