Specverge

Compare API contract revisions, classify breaking changes, map affected consumers, and retain release evidence before deployment.

Focused field tools

Compatibility

Classify additive, behavioral, and breaking changes before release.

Consumers

Name every generated client, integration, script, and downstream contract owner.

Schemas

Compare type, requiredness, constraints, defaults, nullability, and examples.

Endpoints

Record path, method, parameters, response codes, and lifecycle state.

Enums

Treat removed or newly rejected values as consumer-visible behavior.

Security

Review scopes, headers, token rules, and unauthenticated assumptions.

Specverge analyzes recorded contract revisions and assumptions; it does not prove runtime compatibility. Validate generated clients, undocumented consumers, authentication, examples, replay fixtures, rollout order, and production behavior with accountable service owners.
