About Specverge: API Contract
Specverge is a private API contract review workbench for backend, mobile, platform, QA, and integration teams that need a dependable compatibility gate without a hosted service.
Compare two recorded contract states with consumer impact, confidence, and accountable release evidence.
KEY FEATURES
- Side-by-side current and proposed contract lanes
- Breaking-change risk scoring
- Consumer-count and coverage weighting
- Endpoint, field, enum, and security records
- Editable owner and disposition state
- CSV workspace import
- Priority compatibility findings
- Decision and deprecation log
- Local PDF and JSON export
- 110 original offline technical plates

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.
