Uptime, SSL and API monitoring for developers who'd rather not babysit it

Ten monitors, one-minute checks and a status page are free forever — no card. Add a URL, pick the assertions, and PulseTrace tells you in Slack or Discord when it breaks, when the certificate is about to expire, and when something about the endpoint quietly changed.

Sounds familiar?

  • The side project went down on Saturday and you found out from a user on Monday.
  • A Let's Encrypt renewal failed silently and the browser warning was the first sign.
  • The API 'works' but a deploy changed a response shape and the client broke.

Which plan

Free covers most solo projects: 10 monitors, 1-minute checks from one region, one status page. Team ($29) adds 30-second checks, three regions, Slack and Discord destinations and incident management when a project becomes a product.

The setup

  1. 1

    Start with HTTP monitors with assertions

    One monitor per endpoint that matters, asserting on status, a header or a JSON path — so a 200 with the wrong body is still an alert.

    HTTP(S) monitor →
  2. 2

    Let the TLS monitor watch expiry

    Every HTTPS host gets a TLS monitor for free; the default alert fires 7 days before the certificate expires, and grading on Team+ tells you what else is weak.

  3. 3

    Alert where you already are

    Slack, Discord or Telegram via a webhook takes a minute to connect; email works out of the box.

  4. 4

    Publish a status page

    One public page is included on Free — link it from your README or app footer instead of answering 'is it down?' DMs.

Questions from developers teams

Do I need a credit card for the free plan?
No. Free is free forever, with no trial timer and no card; upgrade only if you need more monitors, faster checks or more regions.
Can I manage monitors from code or an AI assistant?
Yes — the REST API covers everything the UI does, an OpenAPI import creates monitors from your spec, and the MCP server lets Claude, Cursor or any MCP-capable agent list, create and inspect monitors.
Does PulseTrace monitor localhost or a private network?
The hosted probes need a public target. For internal services, run the probe agent inside your network and it reports back the same way.
