Doxygen vs StepShot

Doxygen is a free documentation generator that turns source-code comments into reference material, parsing items such as classes, functions and variables. It supports C/C++, Lex, Java, Python, VHDL, PHP IDL, C#, Fortran, Objective-C 2.0 and some D sources. Output can be generated as HTML, PDF through LaTeX, Word through RTF or structured XML for external tools. Graphviz’s dot tool can add include-dependency, collaboration, call, directory-structure and class-hierarchy diagrams. Doxywizard provides a graphical interface for editing settings and running the generator on Windows, Linux and macOS; Doxygen also works on many Unix flavors. It supports HTML Help, docsets, Qt-Help and Eclipse Help, with more than 100 configurable options. The tool runs without registration and does not collect personal or usage data. It is self-hosted and licensed under the GNU General Public License, without express or implied warranty. Help is listed through Stack Overflow and the doxygen users mailing list; commercial feature and bug-fix support has limited capacity.

StepShot is a macOS app that turns recorded workflows into step-by-step tutorials, standard operating procedures, and training documents. It captures activity through action-driven capture or screen recording, using cursor pauses as an additional cue for splitting recordings into steps. Users can edit steps and annotations, then export to PDF, Markdown, or HTML. Capture, editing, and all three export formats work locally without an internet connection. Optional AI assistance can suggest improvements to titles, descriptions, and step order; users review suggestions individually before applying them. Cloud planning requires a connection and a user-supplied OpenAI-compatible endpoint, API, and quota. The free plan costs nothing, allows unlimited capture and editing, and exports only the first 10 steps in Markdown or HTML. Pro costs 269 CNY, paid once and adds unlimited steps, PDF export, branding, optional cloud planning, and activation on two devices. Team costs 899 CNY, paid once and adds five-device activation, shared brand presets, bulk licensing, centralized invoicing, and priority feedback handling. StepShot requires macOS 14 or later and supports Apple Silicon and Intel.
