FAQ

How does the Slack integration work?

You provide your Slack incoming webhook URL in the dashboard. When an alert triggers, we POST a formatted message directly to your chosen Slack channel with endpoint name, response time, and threshold details.

What counts as a performance degradation?

You set a response time threshold per endpoint (e.g. 500ms). We also detect statistical anomalies — if response times suddenly spike above your rolling average, you get alerted even if you haven't hit the hard threshold.

Can I cancel anytime?

Yes. Your subscription is managed through Lemon Squeezy. You can cancel from your billing portal at any time and you won't be charged again.
