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.
Monitoring thatgoes beyond alerting.
Track cron jobs, websites, APIs, SSL certificates and DNS, get alerts where your team works, and keep an incident timeline. Route incidents to the right team and trigger approved workflows.
No credit card required
- Step 1 of 4, Detect: A nightly job fails at 02:07 and an issue opens.
- Step 2 of 4, Route: A routing rule sends it to the team that owns it.
- Step 3 of 4, Act: On-call opens the issue from Slack and acknowledges it.
- Step 4 of 4, Resolve: The rerun reports COMPLETE: resolved, with the timeline kept.

Take our early testers' word for it.
Opens in a new tab
“I sleep better knowing FastMonitor is watching my services. It's already caught things I would have missed until a client called.”
“Dead simple to set up and it just works. I had my first monitor running in under five minutes.”
“Does exactly what it needs to do without getting in the way. Really good monitoring tool.”
“The alerts actually tell you what went wrong. Real context, straight to Slack. Not just 'something is down'.”
“Lovely interface, no unnecessary complexity, and it's always the first to tell me something's off. I use it across all my side projects.”
“We were hearing about outages from customers before our own tools caught them. FastMonitor changed that completely.”
“Easy to set up, does what it says, and the cron monitoring is genuinely useful. Recommended.”

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.
There is no automation screen in the dashboard yet: our team sets up your automation rules and handles run approvals with you, on request. Talk to us
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.
Diagnose an incident in one click
On any open issue, generate a short summary of what went wrong, the likely causes and suggested next steps.
Shows what it looked at
Every diagnosis lists the check results, issue and monitor it was based on, and stays on the issue for your team.
Secrets stay out
Before anything reaches the AI provider, URLs are cut down to the host and keys, headers, bodies and recipients are removed.

vs Oh Dear
Full routing and action control
FastMonitor routes alerts by tag, severity, environment and schedule, opens an issue, and runs approved automation such as an n8n workflow or a status-page update. Oh Dear alerts you and stops there.
vs Cronitor
No seat tax. Better orchestration.
FastMonitor does not charge per seat: invite your whole team to your organization on any plan. You also get routing logic and workflow automation that Cronitor's Business tier does not offer.
vs Better Stack
Focused, fast, and action-first.
FastMonitor is purpose-built for detection, routing, and action. You get incident workflows, automation, and approval gates without buying a full observability platform.
