How it works

A real browser, not a guess

Most “map broken” advice is a forum thread from 2016. We reproduce the failure on your actual page and match the signature to a documented fix.

01

Render & capture

We load your URL headlessly, wait for the map container, and record console output, network responses and the API key’s referrer handshake.

02

Match the signature

Each captured error is matched against 16 documented failure modes — key restrictions, billing, quota, deprecated loaders, CSP blocks, ad-blocker interference.

03

Get the exact steps

Every finding links to a step-by-step fix written for your stack, with the console screens you’ll actually see and a re-check button when you’re done.
