Preventionlabs
See what's broken on a live website from the outside: errors, uptime, DNS, HTTPS, leaked files.
Preventionlabs checks a website the way visitors, Google, and email see it, then reports what is wrong and how to fix it. The first report is free without needing a credit card, then the service costs A$50 per month for up to 10 domains. Users must prove they own the domain before the scan runs.
A single check runs up to 25 checks, with 16 requiring only the domain; connecting a Cloudflare account adds additional data. The report can be copied and sent to a developer or AI assistant, or the user can fix the issue directly. Uptime is monitored every 5 minutes with alerts for downtime.
