Webflow sites in the Consent Gap Index

Webflow is a visual website builder. A designer assembles the page in Webflow's editor and Webflow hosts and serves the result, so the tool tends to be used for marketing sites, product pages and company homepages rather than applications. It is detectable from the outside, which is how this index found it on 106 sites out of the 5,294 measured. Of the 13 site-building and hosting platforms recorded here, Webflow sites carry the heaviest median page — and that has more to do with who builds on it than with the builder.

Three measures where Webflow ranks first of thirteen

The median Webflow site made 73 requests to third-party hosts — the highest median request count of the 13 platforms in this index, rank 1 of 13. Its median count of companies contacted before a consent choice could have been recorded is 8, also the highest of the 13. And 98.1 percent of its sites saw early contact at all, again rank 1 of 13.

Median companies contacted, 9, ranks 2nd of 13; median trackers, 2, ranks 3rd. So this is not one outlier measure dragging the rest along. On every volume measure the platform sits at or near the top of its field.

Who is actually on this list

The 106 sites are not a random draw of Webflow customers. Six of the twelve example sites recorded for this entry are advertising companies' own marketing sites: media.net, smartadserver.com, sharethrough.com, gumgum.com, moloco.com and seedtag.com, plus flashtalking.com in the same business. Companies that sell advertising technology run marketing stacks on their own websites, and those stacks are the heaviest ones this crawl sees anywhere.

The rest of the set is more ordinary: discord.com, discord.gg and discordapp.com, flickr.com, anthropic.com. A builder does not choose a site's third parties; the people who build on it do. What the ranking above measures is the population Webflow attracted in the top of this crawl, not something Webflow inserts.

The examples, in order of how much waited

In most of these examples nothing waited at all. discord.gg contacted 7 companies and all 7 arrived before the window closed, first contact 325 ms, behind a OneTrust banner. discord.com: the same 7 and 7, at 524 ms. flickr.com: 8 and 8, at 457 ms, behind an Osano banner. smartadserver.com: 7 and 7, at 667 ms, with no banner detected. anthropic.com: 4 and 4, at 261 ms. seedtag.com is the fullest case at 13 companies, all 13 early, first contact 430 ms.

Two examples differ. moloco.com contacted 10 companies with 9 early. flashtalking.com contacted 15 with 12 early, first contact 746 ms. Across all 106 sites the median count of companies appearing after the window closed is 0.

Half of them showed a banner

51 of the 106 sites carried a consent tool the crawl could detect. OneTrust was seen alongside on 25 of them, an IAB TCF consent tool on 6, Osano on 5, Cookiebot on 5, CookieYes on 4 and Usercentrics on 3. A site can run more than one banner and each recognised tool is counted, so those numbers are not shares of the 51 and are not meant to sum to it.

The half without a detectable banner is the plainer half of the story: on 55 sites there was nothing for a visitor to answer, and the third parties loaded on the terms the builder shipped.

Timing

Median first contact on a Webflow site was 586 ms, which ranks 11th of the 13 platforms here, where rank 1 is the longest wait. The earliest single first contact recorded was 99 ms.

Put next to the request count, that is the shape of the finding: these pages are both busy and quick off the mark. gumgum.com reached 8 companies with first contact at 200 ms; media.net reached 8 with first contact at 745 ms behind an IAB TCF banner.

What a Webflow site owner can read from this

The platform ranking says nothing about a specific site. It says that the Webflow sites in the top of this crawl carry, at the median, 73 third-party requests and 8 companies arriving before consent could be recorded — and that the range runs from 4 companies to 15.

Every one of those third parties was added by the site's owner: an analytics snippet, a chat widget, an ad pixel, an embedded font. That is also the part a site owner can change. MurmStack measures the same thing on a single page, live, if you want the number for your own site rather than the median for the platform.

The six most common are listed. The remaining 3 of 51 sites with a banner carry something outside that six. One tool is recorded per site, so these counts never overlap.

Questions

What is Webflow?

A visual website builder and host. Sites are designed in its editor and served from its infrastructure, which is why the platform is detectable from outside. This index found it on 106 of 5,294 measured sites.

Does Webflow add trackers to sites?

This measurement cannot attribute a third party to the builder. It records what each page contacted. The heavy medians here come from a set that includes seven advertising-industry marketing sites among twelve examples, which is a fact about the sample, not about the tool.

How heavy is a typical Webflow site here?

73 requests to 9 companies at the median, 2 of them classified as tracking. That request count is rank 1 of the 13 platforms in this index.

How many Webflow sites had a cookie banner?

51 of 106. OneTrust was the tool seen alongside most often, on 25 sites.

Did anything load after the consent window on these sites?

At the median, no — the median count of companies appearing after the window closed is 0, across all 106 sites.
