Everything you need, nothing you don't. Simple API, powerful features.
Zero Config
Works instantly with sensible defaults. No configuration files, no complex setup. Just init and go.
Tiny Bundle
Only 58KB for custom events mode. Choose OTLP mode (176KB) when you need OpenTelemetry compliance.
Auto-Capture
Automatically tracks errors, HTTP requests, console logs, and Web Vitals. No manual instrumentation needed.

Track what matters to your business
Beyond auto-capture, use simple APIs to track custom events, metrics, and traces. Correlate user actions with performance data.
- Custom business events
- Performance metrics
- Distributed traces
- User context
// Track custom business events
observe.event('user.signup', { plan: 'premium' });
// Track metrics
observe.metric('checkout.duration', 1234);
// Trace function execution
await observe.trace('process-payment', async () => {
return await processPayment();
});Works with your AI coding tool
Just paste one prompt. We support all major AI platforms.
