Webflow speed check
A free Lighthouse-style audit made for Webflow. Scan the whole site, not one page, and get a speed score, SEO and accessibility checks, and fixes in Webflow's own words, down to the section and class name.
Up to 500 pages in one go, blog posts included. Lighthouse checks one address at a time.
It reads what your site actually sends instead of simulating a slow phone, so the score doesn't jump between runs.
Each check names the panel or setting to change, and points to the page, section and class.
Heavy files, broken links, duplicate titles, an indexable staging site, missing alt text and form labels.
What's using your bandwidth
How it works
How the score works
Each check scores from 0 to 100 by how much it affects the site, and each category averages its checks. The speed score is the average of Images, Video & animation, Loading, and Fonts & code. SEO and accessibility are scored on their own.
Why it differs from Lighthouse
Lighthouse loads one page on a simulated slow phone and times it, so its score moves between runs. This reads every page's code and files directly. Use both: this says what to fix, Lighthouse how it feels.
Authority, for free
Moz DA and Ahrefs DR are paid. The overview shows the free Tranco rank instead: where the site sits among the top million by popularity, with its 30-day trend.
Real visitors
When available, the overview also shows Core Web Vitals from real Chrome visitors over the last 28 days, the numbers Google uses for ranking.
What it can't see
It doesn't run the site's scripts, so files loaded later by interactions or Lottie may be missed. Page weight counts every file a page references, at full size.
Private and free
No sign-up. Up to 500 pages a scan. Your bandwidth CSV is read in your browser and never uploaded.
Make a Webflow site faster
Convert images to WebP
Select images in the Assets panel and convert them to WebP or AVIF. Same look, often half the size. Upload at the largest size they're shown, usually 1920 px wide or less.
Go easy on background videos
Keep them under 2–3 MB and a few seconds long. A desktop and a mobile copy of the same section can mean the video downloads twice.
Lazy load below the fold
Leave images set to lazy load, except the first one people see, which should load eagerly. CSS background images can't lazy load, so use Image elements where you can.
Trim Lottie files
Lotties with embedded images can weigh more than a video. Remove the images, simplify the paths, and only autoplay what's on screen.
Fewer fonts and weights
Every weight is another file. Upload WOFF2, keep to two or three weights, and don't load a Google Font you've also uploaded.
Check your custom code
Chat widgets, tag managers and embeds in site settings often cost more than images. Load them after the page, or on interaction.
