Open Source Wiki Software
Wiki software provides a centralized system for creating and organizing interconnected documentation and knowledge bases. These tools solve the problem of scattered information by using hyperlinks and hierarchical structures to link related notes. This type of software serves teams and individuals who need a shared repository for internal guides and technical manuals. Self-hosting these apps ensures that sensitive company documentation remains on private servers. This approach allows you to manage the storage and access permissions for every page and markdown file without relying on external hosting services.
This page lists 22 open source tools in the Wiki category. The most popular are Outline, Trilium and Wiki.js. Most use the AGPL-3.0 or MIT license, and 16 offer an official Docker image.
