A DSL and Rails engine for documenting RESTful APIs by describing code through Ruby, not comments.
Apipie-rails is a Ruby on Rails engine and DSL for generating and maintaining API documentation. It allows developers to describe RESTful API endpoints using Ruby code within controllers, producing live documentation that can be used for validation and exported as JSON or Swagger specifications. It solves the problem of outdated or separate documentation by keeping it integrated with the codebase.
Ruby on Rails developers building RESTful APIs who need maintainable, integrated documentation and validation. Teams looking for a solution that combines documentation with code to reduce duplication and improve accuracy.
Developers choose Apipie-rails because it leverages Ruby syntax they already know, provides live documentation that updates with code changes, and allows documentation to be reused for validation and other purposes like generating Swagger files, all within the Rails ecosystem.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Describes APIs using Ruby syntax directly in controllers, eliminating separate comment files and keeping documentation close to code, as emphasized in the README's philosophy.
Serves documentation from within the Rails app (e.g., /apipie) and updates automatically in development mode, ensuring docs reflect current code without manual regeneration.
Documentation definitions can be reused for request parameter validation, reducing duplication and enabling consistent checks, with support for custom validators as detailed in the README.
Generates static Swagger/OpenAPI 2.0 files for API specification, facilitating integration with external tools, though the README admits limitations like missing response structure details.
Supports validating API responses against documented schemas in RSpec tests, enhancing test coverage and documentation accuracy through built-in matchers.
Only supports Swagger/OpenAPI 2.0, lacking features from newer versions like OpenAPI 3.0, which may limit compatibility with modern API tooling.
Tightly integrated with Ruby on Rails as an engine, making it unusable for projects on other frameworks or languages, reducing flexibility.
The README acknowledges known limitations, such as inability to document response structures fully and exclusion of recorded examples in Swagger files, reducing machine-readability.
While it uses Ruby, the DSL introduces verbosity and learning curve for describing parameters and responses, which can be cumbersome for simple APIs compared to lightweight alternatives.
