MrDoc

MrDoc is a self-hosted knowledge base and wiki platform designed for individuals and small teams. It supports multiple document formats (markdown, rich text, mind maps) and offers granular permissions, making it suitable for internal documentation hubs where access control and data ownership matter. The project includes deployment options like Docker and provides clients across web and desktop, which helps teams keep documentation in one place while still working across devices. For The Stash, it stands out as a flexible alternative to SaaS knowledge tools, especially for users who want a private, deployable documentation system with broader format support than a standard wiki.
