One walk-driven scanner, three levels. If you’re trying to decide which to buy or what they actually contain, this is the breakdown.
Free — Site Check L1
A real cloud browser walks your site, up to about 20 pages of the journey, then scores it. No payment, no login. Returns:
- Score 0-100 with a one-line verdict, for both performance signals and security
- Passive security checks with traffic-light status
- The full list of findings, ranked by severity
- One sample stack-tailored AI fix prompt — so you can see exactly what the paid fixes look like — emailed to you with the saved report once you add your address
The rest of the fix prompts unlock at L2.
£29 — Full report (Site Check L2)
A one-off £29 unlocks the rest of the scan:
- Every stack-tailored AI fix prompt, not just the one sample — each one paste-ready for Lovable, v0, Bolt, Cursor, or Claude Code, naming the issue, your stack, and the exact remediation
- A full PDF report you can download and share with a developer or keep as your record
Best for: anyone who wants to actually fix what the free walk found, and have a shareable document to hand to a developer.
£49.99/year — Monitoring (Site Check L3)
Everything in L2, kept fresh:
- A monthly re-walk of your site
- A refreshed report each time, so you catch regressions as you keep shipping
Best for: sites under continuous iteration that want the scan to keep watching, not just snapshot once.
Re-testing
L1 is free and unlimited. A fresh paid re-test is £9.99 each — verify a fix without paying the full £29 again. L3’s monthly re-walk is included in the annual price.
On the roadmap
Load and concurrency testing, and verifiable performance certificates, are coming soon — they are not part of Site Check v1. This article describes what you can buy today; we’ll update it when performance testing lands.
