MCFDoc
by JustGnat
MCFDoc turns a datapack into a documentation file through an in-game screen opened with the mcfdoc command, and it is a Fabric client mod for 1.21.11.
What it does
Players use the MCFDoc screen to generate documentation from a datapack. A text field named Datapack Name/Path takes either a datapack name, which the mod searches for in the current world's datapacks directory, or a full file path. A second field named Output Path takes the full path of the file to write, for example home/me/Documents/output.html. A button labeled Open Browser decides whether the finished document opens automatically in the browser.
The mod runs only on the client, so a server does not need it and players can join without installing it. Files are published for Fabric only, for 1.21.11, with 2.0-1.21.11 as the latest build from 2026-08-11. It is not open source and is released under All rights reserved, though its source code and a wiki are linked publicly.

How it compares
Modrinth Direct is open source under the MIT License and runs client-side only on Fabric for 1.21.1 – 1.21.11. NameManager is also client-side only on Fabric, but it is for 1.21.4 and is not open source. Datapack Error Viewer is open source under the MIT License and covers both client and server on Fabric for 1.21 – 26.3, so it applies where MCFDoc does not.
