LiteSpeed Cache leads each headcount band: 41.8% of the 11,420 companies under 10 employees, 41.6% of the 5,218 companies with 10–50 employees, and 38.0% of the 700 companies over 50 employees. The median headcount is 6 employees for most profiled systems, so the visible market is weighted towards smaller B2B websites rather than larger employers.
After the first two systems, the field drops to W3 Total Cache at 9.4% (1,632 companies), WP Super Cache at 6.7% (1,169 companies), WP-Optimize at 5.0% (862 companies), WP Fastest Cache at 4.8% (834 companies), Redis Object Cache at 3.2% (552 companies) and NitroPack at 2.2% (374 companies). Four further systems cover 534 companies, so the tail is present but fragmented.

How Caching usage is detected
Company data
Detected companies are joined to UK Companies House records and XBRL accounts data. Revenue and headcount figures come from the most recent filed accounts; where the company has not filed, values are estimated using a model trained on filed history and peer benchmarks and are labelled as estimates.
Detection
Firmbase crawls the public website of actively-trading UK companies and fingerprints the technologies present: tracking scripts, embedded forms, chat widgets, CMS markers and similar signatures. A company is included in this list when one or more of the technology's signatures are found on its site; closely-related variants of the same product are grouped under one name. Detection covers what is visible on the public web — a company using the technology purely internally, with no website footprint, will not appear. Counts are therefore a conservative floor, not a ceiling.
Freshness
Websites are re-crawled on a rolling basis and the underlying company data is refreshed from Companies House continuously; filings appear within days of submission. The list and its statistics are regenerated when the detected cohort moves meaningfully. You can see the last-updated timestamp near the top of the page.
