Yes. The free tier monitors 3 endpoints with the full feature set — schema-aware regression detection, OpenAPI contract testing, AI incident analysis, status pages, mobile triage, security fuzz testing. No credit card. Paid tiers start above 3 endpoints.

How is monit.rs different from Pingdom or Uptime Robot?

Traditional uptime monitors check status code and response time. monit.rs additionally learns the schema of each endpoint's responses and detects when fields change, types drift, or status codes break — catching API regressions that look fine to a status-code check but break clients downstream.

What does "schema-aware" mean?

monit.rs records the JSON shape of each endpoint's responses as a baseline, then compares every subsequent response against it. Missing fields and changed types can produce a regression report. Additive fields are learned over time. Send a test notification to check your alert destination.

Can monit.rs replace Statuspage.io for public status pages?

For small-to-mid teams, yes. Every monitored endpoint can be added to a public or private status page at .status.monit.rs with automatic uptime history, incident timelines, and a per-page social preview. Statuspage.io enterprise features like subscriber notifications and component grouping are planned.

Does monit.rs work with OpenAPI / Swagger?

Yes. Import an OpenAPI spec via URL or file and monit.rs creates one monitored endpoint per operation, with the spec as the contract baseline. Subsequent responses are validated against the spec; drift is flagged as a contract regression.

Where is the data hosted?

All monitoring data is stored in PostgreSQL in the United States. Account email and name are the only personal data collected. Account deletion is one-click via https://monit.rs/delete-account and complies with GDPR Article 17.

Is there an iOS or Android app?

Not yet. The web app is mobile-responsive so you can triage incidents from a phone browser; a native mobile client is on the roadmap but not shipped.

How are AI incident summaries generated?

When a regression opens, monit.rs runs the diff plus recent context through an LLM (OpenAI or Anthropic) to produce a plain-English likely-cause and suggested next step. When an analysis is available, its summary accompanies the observed diff. Disabled per-account if preferred.

The anatomy of an API break: 920 events, three findings the taxonomy makes uncomfortable

920 breaking OpenAPI changes across 47 public APIs in 35 days, grouped by kind. Two-thirds are the same event type; the required/optional flag drives most of the ambiguity; two vendors account for 96% of all breakage.

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

Add your endpoint. Paste a URL. Set method + auth. Done.
Baseline learned. monit.rs probes your endpoint and records the expected schema, types, and structure automatically.
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.
