Our verdict on CMinx
CMinx is an open-source documentation generator for developers who want to turn CMake project definitions and related annotations into browsable project documentation. Its scope is specific to CMake, making it a candidate for solo developers and small or mid-market teams whose documentation starts with CMake projects. It is distributed as software to run in a development or build environment, rather than as a hosted subscription service.
The CMake focus is the defining fit decision. CMinx is oriented around CMake as both a source input and a supported language, so teams working primarily with that ecosystem may find the scope appropriate. It is not positioned as a general documentation generator for a broad range of source inputs. If documentation needs span other languages or project formats, a tool with wider input support may be a better match.
CMinx is open source and has a free plan, with self-hosted deployment. The project site provides documentation and usage information for installation and use, and documentation is the listed support channel. This model suits developers comfortable running software in their own environment and consulting project documentation. Choose CMinx when CMake-focused generated documentation is the central need; look elsewhere if a hosted service, broader language coverage, or support beyond documentation is important to the buying decision.
