Error tracking
JavaScript errors with stack traces and browser context. But unlike Sentry, we tell you which errors are blocking conversions.
Broken forms, silent errors, conversion drops. One script finds them. You fix what matters.

Your visitors stay anonymous.
No IP addresses, no form values, no names. Anything that looks like personal data is scrubbed before it leaves the browser.
No consent banners needed.
The tracker uses localStorage, not cookies. No analytics cookies, no ad networks, no cross-site tracking.
Per-domain storage.
Each domain gets its own database file. Your data is never mixed with other customers. Ever.
Not your data.
No advertisers, no data brokers. Delete the script and data stops flowing. Remove your account from settings. No hoops.
Stop switching between tools. One script watches it all.
We check your site every minute from multiple locations. The moment it goes down, you'll know. When it comes back, you'll know that too.
What the script does — and what it doesn't.
We don't set cookies on your visitors' browsers. No consent banners needed.
No IP addresses, no form values, no names. We strip anything that looks like PII automatically.
Loads async. Zero render blocking. Your Lighthouse score won't change.
Delete the script tag and data stops flowing. No residual cookies, no cleanup.
Under 5 KB, async, no cookies. Errors, uptime, speed, conversions, broken links, and alerts. Connected. Not siloed.
JavaScript errors with stack traces and browser context. But unlike Sentry, we tell you which errors are blocking conversions.
Form submits, affiliate clicks, page-based goals. When conversion rate drops, you hear about it before your revenue does.
Checked every minute. Down? You'll know. But more importantly: how many conversion sessions were lost during downtime.
Real performance data from real visitors. Slow pages lose conversions. We connect the speed data to the revenue data.
404s and missing resources logged with referring URLs. Every broken link is traffic leaking out of your funnel.
Scores every issue by conversion impact, traffic baselines, and volume. The reason you don't get 50 alerts a day.
