Argus watches your applications in real time, capturing every unhandled exception and grouping duplicate occurrences into a single issue using stack-fingerprinting. Install one of the SDKs, paste your DSN, and start seeing errors in your dashboard within minutes.

Quickstart

Instrument your first app and see errors flowing into your dashboard in under 5 minutes.

How it works

1

Create a project

Sign up, create an organization, and add your first project. Argus generates a unique DSN for each project.
2

Install an SDK

Add the SDK for your platform — Browser, Node.js, or React — and call init() with your DSN.
3

Errors appear automatically

Uncaught exceptions and unhandled promise rejections are captured automatically. Duplicate errors are grouped into a single issue so you never see the same noise twice.
4

Get alerted

Set up an alert rule to receive an email or webhook notification the moment a new issue is detected.

​
