Detect breaking changes in external APIs before they break production.

DriftMonitor continuously monitors API endpoints and alerts you when JSON schema changes.

External APIs change silently

  • • Fields disappear
  • • Types change
  • • New required fields appear
  • • Integrations break in production

Most integrations with external APIs look stable in staging, but subtle schema changes often surface only after deployment, where they cause unexpected production failures.

How it works

Step 1

Register an endpoint

Step 2

DriftMonitor builds a schema baseline

Step 3

Future responses are compared

Step 4

Breaking changes trigger alerts

Example schema drift

Baseline schema

user.id: string

user.name: string

user.email: string

New response

user.id: number

breaking change

user.name: string

user.email: string

DriftMonitor compares response schemas over time and alerts you when fields are removed or types change.

Already working

Built for real API monitoring workflows

DriftMonitor is already running in the cloud and supports the core workflow needed to detect schema drift in external APIs.

  • Multi-tenant architecture
  • Manual monitor execution
  • JSON schema snapshots
  • Drift detection
  • Snapshot history
  • Drift analytics
  • Alert pipeline
  • Stripe billing in test mode

Private Alpha

Looking for developers who integrate external APIs

DriftMonitor is currently in private alpha. I'm looking for a small group of developers to test it with real API integrations and share feedback.

Current access is API-only via Swagger.
