  • Explicit verdicts (compatible, breaking, unsafe) with a list of breaking changes
  • Actionable recommendations on release strategy and versioning

Quick Start

Compare the old and new contract definitions to generate a compatibility verdict and identify breaking changes.

FAQPage Schema
How do I check API compatibility between two contract versions?▼

To verify API compatibility, compare old and new contract definitions to generate a verdict. This assessment identifies whether changes are compatible, breaking, or unsafe before shipping public API updates.

What is a breaking change in API versioning?▼

A breaking change in API versioning is a contract modification that disrupts known consumers, libraries, or integrations. Compatibility assessment explicitly enumerates these breaking changes to prevent unintended disruptions.

When do I need to assess backward compatibility for my API?▼

You need to assess backward compatibility when shipping changes to public APIs. This assessment evaluates the impact on known consumers, libraries, and integrations to determine if the update is safe.

Can I get actionable recommendations on release strategy after an API compatibility check?▼

Yes, an API compatibility check provides actionable recommendations on release strategy and versioning. These guidelines are generated alongside the compatibility verdict to help you safely ship contract changes.

Does this compatibility assessment work for internal libraries or only public APIs?▼

This compatibility assessment is applied when shipping changes to public APIs and assessing impact on known consumers, libraries, or integrations. It evaluates contract changes to determine if updates are compatible, breaking, or unsafe.
