OpenAPI Generator
OpenAPI Generator allows generation of API client libraries
With 50+ client generators, you can easily generate code to interact with any server which exposes an OpenAPI document. Maintainers of APIs may also automatically generate and distribute clients as part of official SDKs. Each client supports different options and features, but all templates can be replaced with your own Mustache-based templates. Getting started with server development can be tough, especially if you're evaluating technologies. We can reduce the burden when you bring your own OpenAPI document. Some generators support Inversion of Control, allowing you to iterate on design via your OpenAPI document without worrying about blowing away your entire domain layer when you regenerate code. Ever wanted to iteratively design a MySQL database, but writing table declarations was too tedious? OpenAPI documents allow you to convert the metadata about your API into some other format. -

Optic
Generate, Diff, and Test OpenAPI Descriptions
Vizualize API changes to improve the quality of reviews. Test API changes to ensure nothing bad slips through. OpenAPI diffs are difficult to read.

Optic adds a visual changelog to every Pull Request that makes it easy to see exactly what API changes have been proposed. Optic tests each set of API changes in CI, making it more powerful than a linter. Our built-in checks will help any team ship a more reliable API. OpenAPI diffs are very difficult to review, comprehend and give feedback on. Optic’s changelogs are easy to understand allowing anyone (even non-developers) to participate in review. Optic goes beyond linting OpenAPI, it lets you write test about each set of API changes. We also make it easy to share your API standards. -
