Argus watches your applications around the clock — catching uncaught exceptions and unhandled promise rejections the moment they occur, grouping duplicate crashes into a single issue so you can fix bugs without wading through noise, and alerting you before your users ever file a support ticket.

​
What You Can Do with Argus

Error Tracking

Capture every uncaught exception and unhandled rejection across your apps. Argus automatically groups duplicate errors into a single issue so the same bug never floods your inbox.

SDK Support

Install a lightweight, zero-dependency SDK for the browser, Node.js, or React in seconds. Every SDK follows the same init() API so switching platforms requires minimal changes.

Alerts

Create alert rules that fire the instant a new issue is detected, delivering a notification to your email or a webhook endpoint of your choice.

Performance Monitoring

Track transaction durations and web vitals — LCP, CLS, TTFB, and FCP — so you can catch slowdowns before they become user complaints.

When your organization reaches its monthly event limit, the Argus ingest endpoint returns HTTP 429. The SDK detects this response and drops the event silently — your application keeps running without any errors or retries. Upgrade to Pro from your billing page to restore ingest immediately.
