Svelte error tracking from the browser to the server
A SvelteKit-native SDK that hooks into hooks.client.ts and hooks.server.ts — errors captured on both sides, inbound requests traced automatically, and source maps wired in by a Vite plugin. With session replay and readable stack traces on the same platform, bug reports stop being guesswork.
Why Svelte apps need real error tracking
SvelteKit apps fail in two places at once. A load function throws on the server, a component breaks in the browser, and neither failure tells you about itself — the user sees an error page, closes the tab, and the evidence is gone. Minified production bundles finish the job: the few stack traces you do get point at compiled chunks, not at the Svelte component that actually broke.
Install the official @sentry/sveltekit package and initialize its client and server hooks with the DSN from AllStak project setup. Follow the official Sentry build instructions for source maps.
Full-stack Svelte monitoring
From a broken component in the browser to the load function behind it, AllStak covers your SvelteKit app on both sides of the wire.
Error tracking
Use the official Sentry SvelteKit error hooks on client and server, and Sentry.captureException for handled failures.
Server request tracing
Server request instrumentation follows the official Sentry SvelteKit integration and the options supported by AllStak.
Session replay
See what the user actually did before the error — clicks, navigation, and the moment it broke — with privacy masking so sensitive input never leaves the browser.
Source maps via Vite
Use the official Sentry SvelteKit source-map setup so minified production frames resolve to your original components.
Outbound HTTP & breadcrumbs
Outbound HTTP instrumentation follows the official Sentry SvelteKit integration and the options enabled for your project.
Alerts & incidents
Get notified the moment a new error appears or an old one spikes — before the support tickets arrive, not after.
Add AllStak in minutes
Install the official @sentry/sveltekit package and initialize the client and server hooks with your AllStak project DSN. Verify an error from each runtime.
npm install @sentry/sveltekit
// src/hooks.client.ts and src/hooks.server.ts
import * as Sentry from '@sentry/sveltekit';
Sentry.init({
dsn: process.env.ALLSTAK_DSN,
environment: process.env['NODE_ENV'],
});
export const handleError = Sentry.handleErrorWithSentry();Follow the official Sentry SvelteKit source-map setup and keep the AllStak DSN in runtime configuration, not in source. full setup guide · SDK reference.
What you see in AllStak
Error detail with full context
Open any issue to a readable stack trace (via source maps), the breadcrumbs leading up to it, and the release it shipped in — reproduction without the guesswork.
Session replay of the failure
Watch the user's session around the error — what they clicked, where they navigated, and what the page looked like when it broke.
Client and server in one trace
Configure supported trace propagation through the official Sentry SvelteKit integration and verify it before rollout.
Unified real-time dashboard
Frontend errors next to the backend errors, logs, and uptime of the APIs behind them — one dashboard, in English or Arabic, for the whole team.

- Session replay and source maps turn vague bug reports into watchable, readable evidence.
- Use the official Sentry build tooling for SvelteKit source maps.
- Predictable SAR pricing with a genuine free tier — start without a credit card.
- Data stays in Saudi Arabia, with an English and Arabic dashboard for the whole team.
Svelte monitoring FAQ
How do I add error tracking to a SvelteKit app?
Install @sentry/sveltekit, initialize it with the DSN from AllStak project setup, and wire the official SvelteKit hooks on both client and server. Follow the official source-map instructions for production builds.
Does AllStak support Svelte 5 error boundaries?
Yes. createErrorBoundaryHandler returns an onerror handler you pass to svelte:boundary, so a failing subtree reports the error to AllStak while your failed snippet renders a fallback — the page stays up and you still get the full report.
Is AllStak free for Svelte?
Yes. AllStak has a free tier you can start on without a credit card, and the official Sentry SvelteKit SDK is open source.
Is AllStak a Sentry alternative for Svelte?
Yes. You get SvelteKit error tracking with source maps and session replay like Sentry, plus the logs, uptime, and infrastructure monitoring of your backend on the same platform — one SAR bill and data stored in Saudi Arabia instead of a stack of separate tools.
Will the SDK slow down my Svelte app?
The SDK is built for production: capture hooks are lightweight, telemetry ships in the background, and the server handle adds a thin span around requests you were already serving. Your users' experience isn't meaningfully affected.
