Vigilia for the browser

Know when your live app breaks, in plain language, with a fix your AI can apply. This is the browser SDK behind Vigilia: it catches errors, failed and slow requests, rage clicks and page speed from real visitors. Your dashboard turns them into incidents: what went wrong, who it affects, and a fix prompt for Lovable, Bolt, Cursor or Claude Code.

• Zero dependencies, under 10 KB, and it never throws into your app.
• Personal data is scrubbed in the browser before anything is sent: emails, tokens, card-like numbers and query strings.

Install

npm install @getvigilia/browser

import { init } from '@getvigilia/browser';

init({
  key: 'vgl_…',                        // your app's public key
  endpoint: 'https://…/v1/events',     // shown on your app's install page
});

Call init once, as early as you can (your entry file or root layout). It does nothing on the server, so it is safe in server-rendered apps.

If your site sends a Content-Security-Policy, bundling the SDK means you only need to allow the endpoint in connect-src. There's no script host to add.

Also

import { capture, breadcrumb } from '@getvigilia/browser';

try { risky(); } catch (err) { capture(err, 'saving the draft'); }
breadcrumb('opened the pricing dialog');

Prefer a script tag? https://cdn.getvigilia.com/vigilia.js is the same SDK, and it starts itself from its data-key attribute.
