What monit.rs does

monit.rs compares observed response fields and types with a learned baseline. Run OpenAPI contract checks against the latest stored response when you want to compare the implementation with a declared contract.

See the difference when a field disappears or changes type. Optional AI summaries suggest possible causes and next steps; review the evidence before accepting a new baseline.

What you get on the free tier

  • Monitor 3 endpoints, full feature set, no credit card
  • Schema-aware regression detection — catches missing fields, type drift, new properties, status shifts
  • OpenAPI contract testing — validate the latest stored response on demand
  • Optional AI summaries — suggested causes and next steps alongside the observed diff
  • Public status pages at <slug>.status.monit.rs — share uptime history with customers
  • Multi-channel alerts — email, Slack, Discord, PagerDuty, webhook
  • Security fuzz testing — AI-generated adversarial edge-case tests to surface input validation gaps
  • MCP server for Claude Desktop / Cursor / Cline (no auth, three tools)

How it works

  1. Add your endpoint. Paste a URL. Set method + auth. Done.
  2. Baseline learned. monit.rs probes your endpoint and records the expected schema, types, and structure automatically.
  3. Regressions caught. Review detected changes and send a test alert to confirm your notification destination.

Public API changelog surface

monit.rs also runs a public changelog of 47+ well-known API vendors (Stripe, GitHub, OpenAI, Cloudflare, Datadog, PostHog, Vercel, Supabase, and 39 more). Every detected OpenAPI change is published at /changelog with per-vendor RSS feeds, stability badges, and side-by-side comparison pages.
