Is Webflow blocked in China?

Not on our measurement — it answered in a median 1,341ms. But no attempt produced a paint at all, and none completed within 60 seconds, so a visitor would see a blank page rather than a slow one.

Why does nothing render?

A page renders when enough of what it references arrives. Where a builder serves its assets from a host that does not answer — we measured Webflow’s asset CDN failing 9 of 9 requests from a Beijing residential line — the document can arrive while the page still has nothing to draw.

Does Webflow work in China?

Webflow answered from inside China and never rendered anything at all. Measured fact: requested three times from a probe inside mainland China (Alibaba Cloud cn-zhangjiakou) on 2026-08-30, webflow.com returned a first byte in a median 1,341ms but recorded no largest-contentful-paint in any attempt and completed none of the three within a 60-second ceiling. That is worse than a slow page: the connection was made, the server responded, and the browser never had enough to draw a screen. There is a related signal in our residential measurement — Webflow’s asset CDN host d3e54v103j8qbb.cloudfront.net failed 9 of 9 requests from a Beijing consumer line, which is the kind of dependency a site builder resolves on your behalf. Serving to Chinese visitors from mainland infrastructure is the fix that removes the crossing, and it is also what puts the ICP filing on the critical path.

What we measured from inside mainland China

Fact	Primary source
Requested three times from a probe inside mainland China (Alibaba Cloud `cn-zhangjiakou`) on 2026-08-30, `webflow.com` returned a first byte in a median 1,341ms, recorded no largest-contentful-paint in any attempt, and completed none of three within a 60-second ceiling.	21YunBox — China delivery census, measured from inside mainland China
Measured across 88 real page loads from a Beijing China Mobile residential broadband line on 2026-08-30, the site-builder asset host `d3e54v103j8qbb.cloudfront.net` failed 9 of 9 requests — a dependency chosen by the platform rather than by the site owner.	21YunBox — paired measurement from a Beijing residential broadband line
Across our wider census of 280 enterprise sites, 34% finished none of their attempts from inside mainland China, and every one of the 57 failing sites in the residential run returned a first byte. What breaks these pages is almost never that the site is unreachable.	21YunBox — paired measurement from a Beijing residential broadband line
