Bulk Lighthouse Mobile Audit (median of 3 runs)
Runs Google Lighthouse on each website in your list, with mobile emulation (or desktop), and returns the median run of up to 3 runs per site. A single Lighthouse run can swing 10+ points; the median is what Google itself recommends reporting.
Output (one row per site)

Example row (real run, zingermans.com, mobile, 3 runs)
{"url": "https://zingermans.com/","device": "mobile","runsCompleted": 3,"performanceAllRuns": [52, 31, 32],"performance": 32,"lcpMs": 8589,"tbtMs": 3563,"topFixes": [{"fix": "Eliminate render-blocking resources", "estimatedSavingsMs": 3571}]}
The spread (52 vs 31) is why one run is not enough: the median is the number to report or compare.

Pricing
Pay per event: one lighthouse-run per completed Lighthouse run. Runs that fail are free. Set runs to 1 for a cheaper single-run scan.
Notes
- Lab data from the Apify cloud, not field data (CrUX). Scores differ from PageSpeed Insights because hardware and network differ; compare sites within one run.
- Public pages only. Nothing is submitted or logged into.
