What it does
Wiki.js is a self-managed wiki application with an administration area and optional modules for areas such as authentication, editors, history, localization, media assets, and rendering. The official site lists PostgreSQL, MySQL, MariaDB, Microsoft SQL Server, and SQLite as supported database choices, and describes public, private, or mixed access configurations.
Check version and infrastructure before installing
A team preparing a wiki should first choose its hosting environment and database, then consult the matching installation guide. Wiki.js lists several database engines and says its modules can be enabled or disabled to suit the installation. Its site also distinguishes a stable 2.x release from a 3.0 beta, so administrators should make a deliberate version choice and consult documentation for that branch rather than assuming the two are interchangeable.
The administration area and configurable permissions make it possible to adapt the wiki to different audiences, but they also mean setup involves more decisions than a hosted document editor. The product page says the software is available under AGPL-v3; this record does not make a separate license determination. No server was installed or tested.
