Drift detection

Every snapshot diff is classified — breaking, warning, and info — so engineers know whether to page on-call or just log the change.

  • Breaking / warning / info on every change
  • Terminal-style diff view in console
  • CSV/JSON export on Pro and Team
  • MIT diff engine for local CI use

Full audit trail per watch

  • Per-watch history bars (24 on Pro)
  • Signed audit JSON on Team
MCP + REST

Same diff engine, every payload

OpenAPI specs, live JSON, and MCP tool schemas all flow through the same classification pipeline.

Coming to Pro & Team

Semantic drift detection

Schema-valid JSON that means something different — unit flips, enum repurposing, stable shape with shifted values. The case OpenAPI diffing alone won't catch.

  • Value fingerprints + enum set tracking
  • Unit-suspect and distribution-shift alerts
  • Same breaking / warning / info discipline
