Incidents open and close themselves
A failed check or a missed job opens an issue with a timeline. It resolves on its own when the monitor recovers.
everything it does
Detect, route, act.All in one place.
FastMonitor watches your sites, APIs, certificates, DNS and cron jobs, sends each alert to the right people and takes the next step for you. Here is what it does today, and which plan includes it.

DNS Record Monitoring
Monitor DNS records for unexpected changes. Catch misconfigurations and hijack attempts early.
Website Uptime
Check websites, APIs and TCP ports on a schedule, with assertions on the status code, body and response time. Know before your users do.

Routing
Send alerts to exactly the right person, every time.
- Step 1 of 5, Alert: billing-export reports FAIL at 02:07. Its alert enters routing with the monitor's environment, group and the time.
- Step 2 of 5, Rules: Rules run in priority order. Each checks its conditions: environment, monitor group and a schedule in your timezone. If no rule matches, the monitor's own notification list is alerted. Staging jobs does not match: its environment is staging. Payments, office hours does not match: 02:07 is outside 09:00-18:00.
- Step 3 of 5, Match: "Payments, out of hours" matches: production, the Payments group, and 02:07 is inside 18:00-09:00.
- Step 4 of 5, List: The rule's target is the Payments on-call notification list.
- Step 5 of 5, Deliver: Payments on-call posts to Slack #payments-alerts and triggers a PagerDuty incident.
Action
Go beyond alerting. Take the next step automatically.
When a job fails at night
- Step 1 of 5, Issue: billing-export reports FAIL at 02:07, so an issue opens with a timeline.
- Step 2 of 5, Hold: An automation rule starts an N8N run for your recovery workflow and holds it for approval.
- Step 3 of 5, Retry: Once approved, the first attempt gets a 503, so the run retries with backoff and gets 200 OK.
- Step 4 of 5, Status page: A STATUS_PAGE_UPDATE action adds an update to the incident on your status page.
- Step 5 of 5, Resolved: The rerun reports COMPLETE and the issue resolves on its own. Every run keeps an audit trail.
Your status page follows along
Incidents from your monitors show up on your public status page and clear when they resolve.
Run a workflow when an alert fires
Send a signed webhook to your own service, or start an n8n workflow with the alert details.
Hold runs for approval
A rule can hold each run until it is approved, and every run keeps an audit trail of who approved it and what happened.
Raise a ticket, post an update
Raise a FastMonitor support ticket with the incident details, or add an update to the incident on your status page.

AI
A second pair of eyes on every incident.
Ask from your coding assistant
Connect Claude Code, Codex or Hermes to FastMonitor's MCP endpoint with a scoped token. It reads your monitors and issues, and can acknowledge an issue.
- Step 1 of 4, Ask: In your coding assistant: "Why did billing-export fail last night?".
- Step 2 of 4, Issues: The assistant calls list_open_issues and finds the open billing-export issue.
- Step 3 of 4, Timeline: get_issue_summary and get_monitor_summary return the issue's recent updates and the monitor's last run and state.
- Step 4 of 4, Answer: It answers from those results only: what failed, when, and who was alerted, then suggests a next step.
