As of 4 November 2026, ESP32 is named by 220 companies and Arduino by 467; Arduino skews to companies under 200 people (52% vs 62%), ESP32 to companies over 1,000 (19% vs 30%).
As of 4 November 2026 · refreshed daily · counts move as websites, DNS and career sites are re-read.
The website-and-DNS footprint is not comparable between a marketing suite and a CRM: Arduino's script and mail records show on hundreds of thousands of small sites, ESP32 rarely leaves a trace outside its own apps. Compare on the job-posting numbers; use the footprint for reach.

Read from the source, not self-reported
Every number on this page can be traced to a page we crawled or a posting we read. Full methodology →
- Job postingsRead hourly from career sites. A tool counts when the employer's own text names it as the team's system; both tools can count for one company.
- Website and DNSScripts and embeds on the company's pages, plus SPF, DKIM, MX and CNAME records of its domain that point at the vendor.
- SegmentsCountry, size and industry from the company profile built from its website.
- Not a reviewNo ratings, prices or feature claims. For those, read the vendors.
