Our best-in-class Swagger-OpenAPI editor puts API documentation power and design guidance at your fingertips:
See your API from the client developer's perspective as you design.
Testing your API couldn't be simpler. Just add example messages; flip the "on" switch to enable the integrated mock service; and test with the live Swagger-UI view, or the testing tool of your choice.
75+ built-in generators from Swagger-Codegen, NSwag and RepreZen let you build API implementation scaffolds, client SDKs, documentation and interchange formats. Configure and generate from the IDE, the command line, or your CI/CD automated build.
And RepreZen API Studio includes a powerful template-driven framework for custom code generation. Start building your own generator in less than 2 minutes. And with advanced generator chaining, you can build even the most sophisticated end-to-end API solutions with confidence.
RepreZen API Studio works with the development platforms you're already using. Built on Eclipse, API Studio supports plug-ins for popular version control systems, issue trackers, and continuous integration platforms. You can branch, merge, commit, manage issues and builds, right from IDE.
