Start monitoring what actually breaks.

Your servers are green and the order still never shipped. SensaCat watches the business process end to end, and tells you the moment a step goes quiet. We're opening access in batches — this form is how you get in.

Flows, not just servers

Stuck orders, unfinished signups and webhooks that never fired — the failures that never show up in CPU graphs.

Silence is the alert

Heartbeats for cron and queue jobs, plus certificate and domain expiry, caught before they bite.

Alerts where your team already is

Email, Slack, Discord, SMS and phone call — escalating automatically when nobody acknowledges.

Get early access

Two required fields. The rest helps us build the right thing.

What SensaCat watches

Business flows

Describe a multi-step process — order placed, payment captured, invoice sent — and get told when an instance stops partway instead of finishing.

Heartbeat monitors

Cron jobs, queue workers and scheduled tasks check in. Miss the window and the job is late; miss the grace period and you get an alert.

Credentials & domains

API keys, certificates and domain registrations get reminders on a schedule, so nothing expires over a weekend.

Uptime & SSL

Domains are probed on an interval, with two consecutive failures before anything is raised, so one flaky check never wakes the team.

How it works

  1. Describe the flow

    Name the steps and how long each one may take before it counts as stalled.

  2. Send events from your app

    One POST per step, with the id of the thing moving through it. No agent, no SDK lock-in.

  3. Get told when it goes quiet

    Email, Slack, Discord, SMS or a phone call, escalating if nobody acknowledges.
