Specverge: API Contract

Diff APIs Before Release

$0.99 · Designed for iPad. Not verified for macOS.

Compare API contract revisions, classify breaking changes, map affected consumers, and retain release evidence before deployment. 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 - No account, ads, analytics, tracking, IAP, or subscription 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.
