Our clear limits
No vague caps. If you need a thousand monitors, on-call phone trees, or Playwright journeys, HetrixTools (or another suite) is the better fit.
- HTTP and TCP checks only (no Playwright, RUM, or transaction scripts)
- 1-minute or 5-minute intervals (not sub-minute)
- Email alerts only today (no SMS, phone, or Slack yet)
- Public status pages coming soon (not shipping today)
- Free launch tier while we gather feedback (not a 1,000+ monitor enterprise suite)
