Free API Security Testing

Use the 42Crunch API security testing tools for free

Our API security testing tools are available to users who have installed our free OpenAPI Editor extension in IDEs and registered with us or are paid customers. Registration is free and only requires an email address. Registration is required so we can send you an access token that activates your free account. Once registered, you can run 100 operation audits and 100 operation scans each month for free. Users with greater usage requirements can upgrade to a paid single-user or team subscription.

Usage of our OpenAPI Editor extension in IDEs to manually create, import and edit OpenAPI contracts, along with using features such as Preview, functional "Try it" testing and intellisense remains free and does not require registration or have usage limits. Registration is only required to access the 42Crunch API security tools (free and paid).

Once you have registered for our free API security testing service (Freemium), you get the following monthly allowances for free in the IDE. Allowances reset every month:

100 operation audits with API Audit - checks the security and quality of the OpenAPI Contracts.
100 operation scans with API Scan - dynamically tests the API to ensure conformance to the API design and ensure the API is free from security vulnerabilities.

An "operation" audit or scan is recognised as a Path + HTTP Method.
