- An error threshold per test, e.g. 5% of users
- Users already on your site finish their scenario

Catch the slow release.

Schedules
Every day, week or month. Results by e‑mail, Slack or webhook.
Only your domains
Tests go only to domains you've verified with a DNS record or a meta tag.
Pay for the time users spend
Runs are measured in virtual-user hours, and every result shows what it used.
See pricingSent from the cloud, not your laptop.
Every virtual user is a real browser on our machines, so your office network never caps the test.
Your site has a breaking point. Find it first.
