If you’ve just shipped an AI-built site and you’re wondering whether it’s safe and whether it’ll perform — that’s the question Site Check is built to answer. No login, no install, no card, no wait.
What it does in one paragraph
You paste a URL. A real cloud browser walks your site the way a user would, up to about 20 pages of the journey. Two analyses run from one walk: a performance read (response times, P95, error rate, slowest page, CDN/WAF detection) and a security read (12 passive checks — HTTPS, security headers, cookies, DNS hygiene, mixed content, form CSRF, trackers, more). Both verdicts land on the same screen, side by side, in about 30 seconds.
What you do with the result
Look at the two scores. If they’re both green, you have a baseline. If either is amber or red, click the finding to see why, then click Copy fix prompt for your AI tool — it generates a paste-ready prompt for Cursor, Claude Code, Lovable, v0, or Bolt that includes the issue, your stack, and the exact remediation. Paste, fix, re-test.
Three levels
- Level 1 (free): what you just ran. Single-user walk, instant verdict.
- Level 2 (£29): 5 concurrent users for 2 minutes. Performance certificate, embeddable badge, public report. Includes a full security analysis.
- Level 3 (£49): 50 concurrent users for 5 minutes. Heavier load, longer-validity cert. Performance only — pen testing alongside a 50-user load is needlessly intrusive.
