Ranked medians
| Rank | Builder | Median | Grade | n | Fully readable | Blocking AI | p25 | p75 |
|---|---|---|---|---|---|---|---|---|
| 1 | Wix | 71.5/75 | A | 26 | 100% | 0% | 67.3 | 73 |
| 2 | Hostinger | 69/75 | A | 26 | 96.2% | 0% | 68 | 70 |
| 3 | Webflow | 58.3/75 | B | 24 | 100% | 4.2% | 53.8 | 69 |
| 4 | Framer | 52/75 | C | 25 | 100% | 0% | 52 | 56 |
| 5 | Lovable | 38.7/75 | D | 24 | 21.7% | 4.2% | 29.2 | 48.9 |
Fully readable means the raw HTML already held at least 80 percent of the rendered words. Wix leads at 71.5/75. Hostinger is next. Webflow and Framer follow. Lovable is fifth, and it is the only ranked builder whose fully-readable rate is under 100 percent (21.7%). The product comparison is best website builder for SEO, measured. Framer against Webflow is Framer vs Webflow. Lovable's failed checks are stepped through on the fix guide.
What was measured
Each homepage was fetched, fingerprinted, and scored with methodology 1.0.0. Readable is 30, crawlable is 15, discoverable is 30, fast is 25. PageSpeed Insights did not run, so Fast is blank and the median is out of 75. Grades use the percent of points that were measured. A builder is ranked at 20 or more sites. WordPress is a baseline and is never ranked. Bolt, v0, Durable, and 10Web have n=0 and stay off this table.
The sample is a public showcase, not a random crawl and not the HTTP Archive technology report. Default builder subdomains are excluded. Parked domains and adult or gambling hostnames are excluded. One origin is kept per site. The methodology is the contract for the weights, and sampling records the Hostinger gap: the public showcase had fewer than 20 live custom domains on 21 October 2026, so a technology index filled that sample.
- Initial public snapshot. Candidates came from public showcase and directory pages, then each homepage was fetched and kept only if its fingerprint matched the builder.
- Default builder subdomains are excluded. Parked domains and adult or gambling hostnames are excluded.
- PageSpeed Insights did not run (no PAGESPEED_API_KEY). Scores are out of 75: Readable 30, Crawlable 15, Discoverable 30. Fast is blank.
- A builder is ranked only when at least 20 sites were measured. Medians within 2 points are a tie. WordPress is a baseline and is never ranked.
- This is not a random crawl of the web. HTTP Archive sampling is the planned monthly source once a BigQuery project is connected.
- Lovable was remeasured after the fingerprint was extended to the public /~flock.js runtime together with id="root" (and the phrase "Lovable hosting"). The first pass only matched the badge, which most published apps omit.
How to use the files
Quote the month file, not only /data/latest.json, so a later month does not change what you cited. Link the builder page if you are talking about one product, and link this report if you are talking about the month. Corrections go to contact@azurotec.com. A correction does not rewrite a published median in place. The next snapshot carries the change, and the methodology changelog says so.
Check a URL if you want one site rather than a builder median. The newsletter is one email when a new month is published.
