Question: I'm looking for a solution that can help me generate OpenAPI documentation for my codebase, can you suggest something?

ReAPI is a full-featured suite with an OpenAPI-based visual API designer that uses AI and ChatGPT to generate schema, examples and documentation. It also includes a no-code test case designer and a serverless cloud runner for detailed test reports. ReAPI also automates API documentation, producing nice-looking and accurate results, and makes it easier for teams to collaborate on and manage APIs.

Another good option is Theneo, which uses AI to generate high-quality documentation with a minimal amount of human setup. It supports several platforms, including OpenAPI, and has features like importing API collections, automatically generating descriptions and summaries, and publishing customizable documents. Theneo integrates with GitHub, GitLab and npm for automated updates so your documentation stays up to date.

If you prefer a more code-centric approach, DocuWriter.ai generates API documentation straight from source code files, which can be more consistent and efficient. It works with all programming languages and has a variety of features, including automatic code documentation, Swagger-compliant JSON format and UML diagram generation. It's geared for developers and teams who want to automate their code documentation and testing.

Last, Alphadoc is an interactive documentation platform that lets developers create, manage and publish high-quality API and SDK documentation. With a visual editor, interactive diagrams and AI-powered search, it's designed to cut down on support requests and improve the developer experience. Alphadoc supports custom domains, styling and flexible collaboration, so it should work for many development teams and scale.
