Works on any Lovable / Bolt / Cursor app
AI explanations in plain English, no jargon
AI explanations in under 60 seconds of an error occurring

Everything you need. Nothing you don't.

Sentry has 150+ configuration options. VibeVisor has one script tag. We built this for founders, not engineering teams.

Error tracking

Captures unhandled JS errors, rejected promises, and network failures automatically. No configuration needed — it works the moment the script loads.

AI error explanations

Every unique error gets a plain-English explanation, a likely cause, and a suggested fix written as a prompt you can paste directly into Lovable or Bolt.

Error context

Every captured error includes the page URL, browser, and the sequence of network requests that led up to it — so you have real context, not just a message.

Network failure tracking

Catches failed API calls, 4xx/5xx responses, and connection timeouts — the errors that don't throw a visible JS exception but still break your app.

PII masking

Tokens, passwords, and email addresses are masked before anything leaves the browser. No sensitive data ever reaches the ingest endpoint.

Smart deduplication

The same bug hitting 500 users triggers one AI explanation, not 500. Errors are fingerprinted by message and call stack — stable across deploys.

Not a stack trace. A fix.

Sentry shows you what broke. VibeVisor tells you why, and gives you a prompt to paste into Lovable or Bolt to fix it.

AI error explanation

high
Your app crashed when a user tried to submit the contact form because it couldn't connect to your email service.
The Resend API key is likely missing or invalid in your environment variables.
"Fix the contact form — the submission is failing because the Resend API key may not be set. Add friendly error handling so users see a message if the email fails to send."
TypeError: Cannot read properties of null at handleSubmit (app.js:142) at HTMLFormElement.submit

Error is captured automatically

No logging calls. No try/catch. The SDK hooks into the browser's error events and catches everything — including errors in third-party scripts.

2

AI explanation fires asynchronously

Claude reads the error message, stack trace, and what the user was doing. It outputs plain English — not "Cannot read property of undefined."

3

You get a prompt ready to paste

The suggested fix is written as something you can drop directly into Lovable, Bolt, or Cursor. No translation required — just copy and fix.

Three views. That's it.

Error feed, raw events, project settings. We kept it that simple on purpose — because the last thing you need is another dashboard to learn.

Your app crashed on the dashboard page when a user's session expired while they were viewing a project.

Likely cause
The user object is null when the session token expires mid-page. The component tries to access user.id before checking if user exists.
Suggested fix — paste into Lovable
"Fix the dashboard — it crashes when the user session expires. Add a null check before accessing user.id and redirect to the login page if the user is not authenticated."

Paste one script tag

Add the script tag to your app's HTML — in Lovable's settings, or directly in your index.html. That's the entire integration.
