Pixlog's Performance Lab crawls your site from 47 edge PoPs, scores every product and hero image against Lighthouse, Web Vitals and Core Image metrics, and ships a written diagnostic to your inbox. No login. No credit card. No sales call.
NO CREDIT CARD/AUDIT IN 20 MIN/SOC 2 TYPE II
Each run crawls every public image on the submitted URL and returns a scored report across four diagnostic categories. No estimates, no modeled data — real numbers from real edge fetches.
Total image bytes shipped per page, broken down by hero, product grid, thumbnail and below-fold assets. The single number that moves Lighthouse more than any other.
Detection of AVIF, WebP, JPEG XL and HEIC delivery per visitor device — plus how many images are still served as legacy JPEG or PNG where a modern codec would shrink payload 40-65%.
Largest Contentful Paint timing per page, with the offending hero or product image isolated. Includes CLS from images without explicit dimensions and the cumulative layout shift contribution.
Time-to-first-byte from each PoP, cache-hit ratio on returning assets, and whether the origin is shipping with stale or missing Cache-Control headers that force revalidation.
Each pair below is a production site audited and deployed in the last 90 days. Names redacted under customer NDA. Payload, LCP and Lighthouse deltas are post-deploy, measured by the customer's own RUM vendor.
Image & Media Optimization Wave, scoring 4.7/5 on time-to-value across the eight vendors evaluated.
412 verified reviews averaging 4.8/5 — the highest satisfaction score in the category.
Median image payload reduction within 10 minutes of install — verified across 312 production sites.
Recognized in the E-commerce category for the per-device format selection pipeline.
The technical questions your team will ask before submitting a URL — answered up front, no sales call required.
From all 47 Pixlog edge PoPs in parallel — Frankfurt, São Paulo, Singapore, Sydney, Virginia, Mumbai and 41 others. The report shows the median and p95 numbers across PoPs, not a single-region snapshot.
4 to 7 minutes for most sites. The crawler fetches every public image once per PoP, runs format detection, and assembles the 12-checkpoint score. You'll get an email the moment it's ready.
No login, no OAuth, no install. Submit a public URL and the crawler only fetches what an unauthenticated visitor would see. Authenticated product imagery is not included in the audit by default.
Audit results are stored against your email for 30 days, then purged. We do not sell, share, or enrich the data with third-party intent providers. SOC 2 Type II audited since November 2023.
Paste a public URL. The crawler does the rest — payload, LCP, Lighthouse, format coverage, all 12 checkpoints, in your inbox before your next standup.
