Is my app broken?

Free 30-second health check for apps built with Lovable, Bolt, Replit, v0 and Cursor. See what your users and Google actually see.

Passive check only. We never submit forms or log in.

What we check

Homepage loads

Status, speed, redirects, HTTPS.

Key pages found

Signup, login, pricing, checkout, contact, privacy, terms.

Broken links

Links on your site that lead nowhere.

What Google sees

Raw HTML vs real browser, blank-SPA detection.

Indexability

robots.txt, sitemap, noindex, title/description/canonical/og:image.

Builder detection

So fix prompts match the tool you built with.

JS console errors

Errors your users hit but never report.

Forms & mobile render

Forms appear after load and nothing overflows on phones.

How it works

  1. 1

    Paste URL

    Any public address. No signup.

  2. 2

    30-second passive scan

    Ordinary GET/HEAD requests, like a browser.

  3. 3

    Report with fix prompts

    Copy-paste prompts tailored to your builder.

Sample report

Illustrative example — not a real scan.
