Everything you need to see what's happening

From the first exception to the alert in your inbox — Marsad covers the whole loop, for web and mobile.

Error tracking that groups itself

Exceptions and unhandled rejections are captured, deduplicated into issues, and ranked by impact — with full stack traces and the breadcrumbs that led there.

141return (
142 {items.map((it) => {
143 <Row key={it.id} />

Every request, timed

Each fetch and XHR is logged with method, status, duration and payload — so a slow or failing call is never a mystery.

Source-mapped stacks

Upload source maps and Hermes bundles — minified frames resolve to your real files and line numbers.

Alerts that find you

New issues and volume spikes reach you on Slack, email or webhook, with dedupe and cooldowns.

Every project, one place

Unlimited projects, switched instantly. Your web and mobile apps, side by side.

How it works

Install the SDK

Add the package and call init() with your project key. One line for Next.js, one for Expo.

02

Events stream in

Errors, rejections and network calls are captured automatically — no manual logging required.

03

Triage & fix

Jump from a grouped issue to the exact stack frame, see the breadcrumbs, ship the fix.
