Find broken links on a Webflow site

Webflow sites break links the same way other builders do: a CMS item is unpublished, a Collection slug changes, an asset is replaced on the CDN while the rich text still points at the old src. The designer view looks fine. The published domain does not.

There is no special Webflow API in this extension. You open the published URL in Chrome and scan it. Staging (webflow.io) and production (yoursite.com) can disagree; scan the host users hit. See staging vs production.

Typical failures

• Collection template still linking to a deleted item
• Nav built as a symbol, duplicated, one copy stale
• Background images vs <img>: the scan covers img src and data-src. Pure CSS backgrounds are a different pass. We do not pretend otherwise. Details on broken images.
• Third-party form or calendar embeds on HTTP inside HTTPS (mixed content)

Pass

1. Publish.
2. Open production, pin the extension, run the page on home and a CMS template.
3. Whole-site crawl if the Collection is large. Export CSV into the Webflow Editor ticket.
4. After you republish, rescan the same URL. Webflow’s CDN can sit on an old asset for a minute.

Do not hunt a second “Webflow plugin” unless you need Editor-side automation. For a check of what visitors get, the browser is the right place.
