Apidog▲570Development teams often struggle with using multiple tools like Postman and Swagger for API design, development, and testing. This fragmented approach leads to outdated API specs and chaotic collaboration. So we built Apidog: a single, unified API platform for team collaboration. It has a beautiful interface that makes it easy to create API spec, generate request data from API spec, validate responses, create mock data, orchestrate test scenarios, and publish API documentation. Apidog = Postman + Swagger + Mock + JMeter.

I frequently face numerous challenges when working with third-party APIs - error handling, logging, caching, retries, mocking, and more. I spent hours making them work, so I created an app to automate integrations. Currently, the platform offers the following functionality: - Set up services with multiple endpoints: Configure caching, retries, mocking, response transformation, and fallback responses. - Define authentication:- Real-time Swagger/OpenAPI integration: Test your endpoints directly in the browser. - Handy code snippets: Easily copy and paste requests. Feedback needed!
