One scan, a real catalog
166 tools checked, across every category that matters.
A tool can show up as a script tag, a CSS class, a meta tag, or a URL pattern — any match counts as a detection. Kajabi shows up as a checkout URL; Calendly as a script tag; Stripe checks four different patterns at once.
Turns into a signal, not just a fact
Track a competitor's tool. Score every lead that runs it.
"Using competitor tool" is one of three signals Kercel scores on every lead automatically, no setup required. The evidence is always spelled out — never a silent number.
Using competitor tool
2/2Detected tracked competitor tool(s): Paperbell — active multi-tool usage.
The same scan catches growth, too
Hiring, funding, and headcount — timing signals from public pages.
A careers page that lists open roles, a funding announcement, a growing team — Kercel reads these as reasons to act now, not just background noise.
Built for useful context, not more noise.
