Under 10 employees
61.9% of band
This is the largest band, with 478 companies, and Slider Revolution accounts for 61.5%. Other Widgets systems compete for the remainder of a micro-company market.
10–50 employees
46.9% of band
This band has 243 companies, with Slider Revolution still first at 46.5%. The lower share leaves more room for Embedly, Elfsight and the wider set of Widgets systems than in Under 10 employees.
Over 50 employees
38.1% of band
Only 21 companies sit in this band, so shares are sensitive to small changes in adoption. Slider Revolution remains first at 38.1%, but the band is less concentrated than the smaller employee groups.
How Widgets 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.
