Openapi.security, a fast security checker for REST-based API

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…

In plain words

Openapi.security is an online tool that runs a dozen security tests on REST APIs defined with OpenAPI or Swagger specifications. It requires no signup or email and works directly from an API specification. The tool uses feedback-driven API exploration with graph traversal algorithms to identify and execute relevant security test cases automatically. It is designed for developers and security teams who need to quickly assess the security posture of REST-based APIs.

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself.
