When Up Isn't Enough

Your uptime monitor can show 100% while

Login authentication silently fails

The server responds 200, but the authentication flow breaks due to token or session issues.

Checkout returns HTTP 500

The homepage loads, but payment fails after the final step.

Third-party APIs time out

Your app is up, but Stripe, Auth0 or another dependency is not responding properly.

JavaScript errors block user actions

The page loads, but a JS exception prevents form submission or button clicks.

Synthetic tests validate real user journeys, not just server availability.

Frequently Asked Questions

What is a Synthetic Test and why should I use it?

Synthetic Tests let you proactively monitor your most important user journeys — things like logins, sign-ups, or checkouts. Instead of waiting for a customer to report an issue, you’ll know the moment something stops working. This helps you catch problems earlier, reduce support tickets, and deliver a smoother experience to every visitor.

Do I need to know coding to set up a test?

Not at all. You can record tests directly through our browser extension or dashboard. Just click through your site as a user would — we’ll capture every step and replay it automatically, no code required.

Which regions and countries do you run tests from?

We cover major global regions including Europe, North America, South America, Asia, and Oceania. Tests can run from cities like Paris, London, Frankfurt, Sydney, Tokyo, and more, so you can see exactly how your site performs where your users are.

Can I simulate logins, forms, and checkouts?

Yes. Our recorder captures multi-step flows including authentication, shopping cart checkouts, and form submissions. This ensures you can continuously verify critical paths that drive your business.

Are my credentials and sensitive data encrypted?

Absolutely. All sensitive data is encrypted in transit (TLS 1.2+) and at rest (AES-256). Login details are stored securely and never exposed in plain text. We follow best practices to keep your credentials and test data protected.

How is pricing calculated for Synthetic Tests?

Our pricing is based on execution time rather than the number of runs. Each test is billed per second of runtime, so whether your journey takes 10 seconds or 2 minutes, you only pay for the actual duration. This ensures transparent, usage-based pricing with no hidden costs.

Can I integrate alerts with Slack, Teams, Discord, or webhooks?

Yes. We support native integrations with Slack, Microsoft Teams, and Discord, plus configurable webhooks if you want to connect alerts to your own systems. You’ll know instantly if something goes wrong — wherever your team works.
