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 This fragmented approach leads to outdated API specs and chaotic collaboration.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.

Hi, this is Mish and Sebastian. We are working on Step CI - a fully automated API testing platform for developers. Step CI works programming-language independent and for different API paradigms (REST, GraphQL, XML). Our CLI and test runner are available on GitHub (https://github.com/stepci) under the MPLv2 license. Since our last launch, Step CI is now able to generate automated tests for your API based on your OpenAPI (Swagger) spec. This saves you a lot of time as you never have to write and maintain your tests again! We would like to invite you to try our tool and give us…

tl;dr we released openapi.security, an online tool that performs a dozen of security tests on any given openapi/swagger-based API, with no signup or email required. You can try it here: https://openapi.security My team at Escape (YC W23) is mainly focused on securing GraphQL APIs. For this, we developed a new approach called Feedback driven API Exploration. Basically, we infer the right security tests cases to run using the specification and a carefully crafted in house graph traversal algorithm. (It's a bit long to describe here but we published a more in depth explanation of…
