Terms of use

Last updated 21 July 2026

VitalsBeacon is a free Lighthouse audit API, provided as is with no warranty, no SLA and no liability for decisions made on the basis of audit results. Scores are lab measurements and can vary between runs. By using the service you accept these terms.

Acceptable use

  • You are responsible for the URLs you submit. Only audit sites you own or have a legitimate reason to measure.
  • Do not use the service to overload or probe sites you do not control, and do not attempt to overload, abuse or probe the service itself. Requests are rate limited and we may block traffic at our discretion, without notice.

What we store

  • Audit results are cached for 24 hours and then deleted automatically.
  • No accounts, no registration and no personal data stored.
  • IP addresses are used in memory for rate limiting only and are not written to storage. We log request metadata for analytics: the audited site's hostname, options, timing and outcome, never full URLs.

Third party sites

An audit loads the submitted page the way a browser would. We claim no rights over audited sites, and you are responsible for having a lawful reason to measure the pages you submit.

Changes

These terms may change. The current version always lives at this page, and continued use of the service means you accept it.
