Three lines to catch every error.
Drop the SDK into your app, and every unhandled exception is captured, deduplicated by stack trace, and turned into a single issue you can act on — not a flood of duplicate alerts.
- 01Install the SDK and set your project API key.
- 02Errors are queued, normalized, and grouped by fingerprint.
- 03Get alerted, see counts and trends, resolve with confidence.
import { Errcheck } from "@_errcheck/node";
Errcheck.init({
apiKey: process.env.ERRCHECK_API_KEY,
environment: "production",
});
try {
parseUserInput(request.body);
} catch (err) {
Errcheck.captureException(err);
throw err;
}Everything you need, nothing you don't.
Errcheck focuses on the core loop of catching, grouping, and resolving errors — fast.
Smart issue grouping
Stack traces are normalized and fingerprinted, so one bug is one issue — never a wall of duplicates.
Real-time ingestion
Events are queued and processed asynchronously, so error reporting never slows down your app.
Ownership-aware access
Every project and issue is scoped to the team that owns it, checked on every read and write.
Built for your stack
Lightweight SDKs for Node, browser JS, and more — install in minutes, not an afternoon.
Alerting that scales
Get notified the moment a new issue appears or a resolved one regresses in production.
Transparent pricing
Pay for event volume, not seats. No surprise bills when your team grows.
