Common questions
Is this a subscription?
No. $29 once and you keep the version you downloaded.
What exactly do I download?
A .zip with the Python source, Windows and macOS/Linux launchers, the report template, a QA checklist PDF, a README and a sample report.
I'm not a developer. Can I use it?
If you can open a terminal and paste one line, yes. The launchers install what they need on first run.
Does it render JavaScript-heavy sites?
The crawler reads the HTML the server returns and does not run JavaScript. The optional Lighthouse run loads the page in Chrome.
Are there limits?
Up to 50 pages per run. Some sites block automated requests, so a few outbound links may show as errors even though they open in a browser.
Will it improve my rankings or make my site secure or compliant?
No tool can promise that. It points out common technical issues for you to fix. It is not a security scan or a compliance certification.
Which platforms were tested?
Tested on Linux. Windows and macOS use the included launchers and standard Chrome/Edge install locations.
Refunds?
See our refund policy: if it doesn't run on your machine and we can't get it working, request a refund within 14 days.
