What is Code2Docs?

Code2Docs is a free, open-source CLI that generates function docs, API endpoint docs and project READMEs from a whole codebase. It runs locally, so source code is not stored or transmitted anywhere.

Code2Docs is an open-source command-line tool that generates documentation from a codebase. It is installed from PyPI as a CLI package and runs on the developer's own machine, reading project files and producing written documentation without a hosted service in the middle. The project is hosted on GitHub and has a Discord server and LinkedIn page for community help and contribution. The current feature set is split into released and planned parts. Three capabilities are marked beta: function-level docs for functions and methods, API endpoint docs with examples and schemas, and project-level READMEs. Two more are listed as coming soon: database schema documentation that visualizes structure and relationships, and architecture diagrams that depict how a system fits together. Buyers should treat the beta items as the real product today and the rest as roadmap. Its target audience is developers and small teams who maintain codebases that have outgrown manual documentation, particularly those who do not want source code leaving their environment. The site states that processing happens locally, that the CLI does not store or transmit code, and that no payment is required because the project is open source. That privacy position is the main reason to pick it over pasting files into a general chat assistant. In practice the workflow is a terminal one: install the package, point it at a project, and receive generated documentation for the whole codebase rather than one file at a time. The maker contrasts this with general assistants such as ChatGPT or Claude, which work well for a single file but require manual effort across a large repository. Code2Docs sits among documentation generators and AI coding helpers as a free, local, repository-wide option. Because several features are still in beta, it suits early adopters who are comfortable with a command line and willing to review generated output before publishing it.

How do you use Code2Docs?

1Install the CLI
Install the code2docs-cli package from PyPI on your machine. It runs entirely locally, so no account or hosted service is needed.
2Open your project
Move into the root folder of the codebase you want documented in a terminal. The tool works across the whole project rather than a single file.
3Generate documentation
Run the CLI to produce function-level docs, API endpoint docs or a project README. These features are in beta, so check the available commands in the package details.
4Review the output
Read the generated documentation for accuracy and edit anything that misreads your code before committing it to the repository.
5Join the community
Use the Discord server or the GitHub repository to ask questions, report issues or contribute to development.
