ReadMe aims to make creating a great developer experience accessible to all by offering a simple, free plan called ReadMe Free, which allows users to start with API Reference Guides. These guides list endpoints and code samples and are an essential part of the developer experience. Unlike some open-source tools, ReadMe Free includes features such as auto-generated code snippets, an interactive playground, and real-time API logs. Users can render Swagger/OAS files, write markdown, utilize search, and customize branding, all while having access to ReadMe's support team. This offering is designed to allow users to begin with basic features and upgrade to a full developer hub as needed without having to switch tools or develop new solutions from scratch.
