Wiki.js

Wiki.js at a glance

Wiki.js is a popular modern open-source wiki built on Node.js, with a polished editor and many authentication and storage options. Wiki.js ships regular releases plus security fixes; as a web application holding organizational knowledge and user accounts, hardening and timely updates matter.

For admins updates run by swapping the application/container and may include database migrations — back up the database and any file storage first, and read the release notes. Keep Wiki.js off the open internet behind authentication and TLS, ideally with SSO and two-factor, since wikis often hold sensitive internal detail. The underlying Node.js and database should stay supported. After upgrading, verify login, content rendering and any storage/git sync integrations. Wiki.js can sync content to a Git backend — a nice backup and audit property worth using. Track the version and its releases; patchletter surfaces new Wiki.js versions so security fixes aren't missed.
