CDN & hosting

Cloudinary in Homepage Source

Cloudinary is a media CDN that stores, transforms and delivers images and video; transformation parameters ride in the URL so assets are resized and reformatted on the fly.

The source-code fingerprint

Delivered assets use res.cloudinary.com/<cloudName>/image/upload/, so that host shows up in img src, srcset and og:image tags.

Likely false positives: Sites can serve Cloudinary media from a custom CNAME, which hides the res.cloudinary.com host and makes this a floor.

How this works

The headline distinguishes candidate upper bounds (index prefilter), estimated matches (a projection from checked samples) and verified matches (an exact count established by the engine). The index contains 131,219,565 homepage documents, one homepage per hostname, including subdomains. The source index was promoted 2026-09-22 and follows a quarterly rebuild schedule. The sample date is when this query was checked against the stored index, not a new crawl of each example site.
