Measure a public page in an isolated browser and inspect observed loading and resource behavior with clear measurement conditions.

- Timing evidence and run conditions
A report with clear boundaries.
Each report lists the checks performed, the resources reached, and any checks skipped. Findings include observed or heuristic confidence so you can judge the evidence.
- Lab measurements vary with environment and do not represent real-user field data.
- Unavailable browser infrastructure is reported as unavailable, never as a passing score.
- A single run cannot establish a Core Web Vitals assessment.

Before you start
What does the free preview include?
1 URL. The preview shows up to five findings with the scope and limitations of the scan. Zero findings means no issues were detected by those checks, not a guarantee that none exist.
What does a paid run include?
Up to 10 URLs per run. A confirmed purchase unlocks the paid allowance and full available findings, plus HTML and PDF exports. Reports remain private to the owning session or account.
Can I check a private target?
This form accepts public targets only. Internal addresses, embedded credentials, unsafe destinations, and unauthorized scans are blocked. Authenticated endpoint credentials are not accepted by this form.
