The complete telemetry platform for browser extensions.
Stop flying blind. Get accurate cross-browser analytics, real retention cohorts, feature usage tracking, and hardware telemetry.
Metrics that actually matter for extensions
Store dashboards only show you vague "active users". We show you exactly what happens inside your extension.
Cross-Browser Analytics
One dashboard for Chrome, Firefox, Edge, and Safari. Unified user counts and retention metrics, no matter where your user is.
Chrome
Firefox
Edge
SafariFeature Usage
Know exactly which features are used. Track button clicks, toggle activations, and flow completions.
Real Retention
Cohort analysis based on actual activity signals, not just "installed" status. See who actually sticks around.
Technical Telemetry
Debug confidently. Collect RAM usage, CPU concurrency, OS version, and screen resolution to optimize performance.
Drop-in SDK for developers
Installing extension.report is as simple as adding a package. Our type-safe SDK handles batching, caching, and retries automatically.
Designed for Manifest V3 first. It plays nice with Service Workers and short-lived environments.
import { init } from "@extension-report/js";
// 1. Track lifecycle automatically (install, update)
const sdk = init({
projectPublicKey: "pk_prod_123456789",
});
// 2. Track custom events
await sdk.track("feature_used", {
name: "pdf_export",
size_mb: 4.2
});
// 3. Identify user (optional)
sdk.identify("user_123");Fair pricing for every stage
