For Developers

Effortlessly design the most secure API contracts with tools you'll love.

Automate. Integrate. Collaborate.

42Crunch makes any developer a security expert. With our integrated set of tools, you can audit your API contract against 300+ security vulnerabilities, we’ll rank them by severity level, and tell you exactly how to fix them – making security a seamless part of your development lifecycle without sacrificing speed or innovation.

Let the 42Crunch Security Audit do all the heavy lifting

Run a 300+ check security audit and instantly get security reports with detailed information on exploit scenarios, risk severity scores for prioritization, and remediation steps with the exact code snippets you need to secure your contract.

Spend less time fixing and more time innovating

Security Audit and Scanning become automated checks ensuring that insecure code never makes it to the master branch and production deployment, and runtime protection policies get automatically redeployed with each API change making sure that you can stay agile without compromising security.

Integrate our plugins with your favorite tools

Integrate our free plugins right into the tools you’re already using, including your integrated development environment (IDE), and continuous integration and continuous delivery (CI/CD) process — work across teams on one platform, easily collaborate without errors, with the freedom you want and the visibility security and operation teams need.
