Multi-region checks catch the outage. On-call schedules, escalation policies and a built-in war room get the right human on it — with status pages your users actually trust.
no credit card · free forever tier · self-hostable
Over 30 check types, probed from every region, with quorum so a single flaky hop never wakes you at 3am.
Probe from anywhere and alert only when a quorum of regions agree it's down. Enable or disable individual regions per monitor.
Real Chromium walks your critical journeys — login, search, checkout — on schedule. A failed step opens an incident with a screenshot and a per-step trace of exactly where it broke.
Point your cron jobs and background workers at a heartbeat URL. Miss a check-in and we open an incident — a dead-man's switch for the jobs no one's watching.
Catch expiring TLS certificates and domain registrations before they lapse, and fail a check when a page stops containing the text it should.
See trouble coming. We watch each monitor's latency and error rate against its own 7-day baseline and flag it the moment it starts sliding — while it's still up.
Point it at a URL and it writes the browser test. When your UI moves, it fixes the test. When CI deploys, it checks the PR. Real Chromium, no scripts to maintain.
The autopilot opens your page in a real browser, reads what's there, and drafts a multi-step journey — login, search, checkout — that you can edit or run as-is. No Playwright to write.
When a button gets renamed and a step stops matching, we inventory the live page and propose the replacement selector. One click to apply — or turn on auto-heal and it patches itself, then re-checks.
Every failed run keeps a video of exactly what the browser did, next to a per-step trace, a screenshot, and the console errors. See the break, don't guess at it.
One curl in CI turns a monitor — or a whole suite — into a commit status on your pull request. Pending the moment you deploy, pass/fail when the journey runs. No GitHub App to install.
Connect Claude Code, Cursor, or any MCP client and ask about your monitors in plain English — or keep them in git and reconcile from CI.
A monitor going down is the start, not the end. Route it to whoever's on call, escalate until someone owns it, and give the team one place to fight the fire.
Daily or weekly rotations with per-person overrides and a live "who's on-call now". DST-safe, so the handoff never drifts an hour twice a year.
Ordered, multi-step ladders that re-page until someone acknowledges. Target a person, the current on-call, or a channel — repeat and hand off automatically.
Escalate to humans, not just chat rooms. Each person has their own contact methods — SMS and email — and every one is tried independently.
Every incident gets a live timeline of who was paged and when, plus a chat panel — with push-to-talk clips and live voice huddles right in the room. No Zoom link, no external provider.
Ack straight from the alert — a signed link in the email, SMS and webhook, or an Acknowledge button in Slack and Teams. One tap halts the escalation.
Open a Jira, Linear or Zendesk ticket automatically the moment an incident starts, with the ack link inside, and sync a comment back when the service recovers.
Tell your users the truth, silence the noise, and run it your way.
Branded public pages on your own domain, verified over DNS, with 90-day history, an incident timeline and email subscribers.
Schedule planned downtime and we suppress the alerts — while still probing and recording the real history.
Deliver to email, webhook, Slack, Discord, Teams, Telegram, PagerDuty, Opsgenie or SMS. Confirmation thresholds kill false alarms.
Two-factor auth, argon2id, and SSRF-guarded probes that can't be turned against your internal network.
A clean REST API — monitors, on-call, policies and incidents — with org-scoped keys, team roles, and a single self-hostable binary. Your data, your rules.
