Build technographic lead lists from JavaScript fingerprints

By SearchWebCode · Updated October 15, 2026 · Lead gen · 2 min read

Pick the footprint of the tool your prospects run, add or exclude a second footprint to qualify them, then export the domains. Choose prepaid credits or a Research/Pro subscription, and enrich contacts yourself.

Technographics, the tools a company runs, are one of the strongest B2B buying signals. If you sell a Shopify app, your market is Shopify stores; if you sell a Klaviyo alternative, it's stores on Klaviyo. When a tool ships an identifiable footprint, you can build that list directly from source instead of buying a stale database.

Compose the query

Start with the platform footprint, then qualify with a second term:

Uses A and B: "cdn.shopify.com" "static.klaviyo.com", Shopify + Klaviyo.
Uses A, not B (switch targets): "wp-content/plugins/woocommerce" -"js.stripe.com/v3", WooCommerce stores not yet on Stripe.
Either of two platforms: "cdn.shopify.com" OR "cdn11.bigcommerce.com".
In a market: append site:de or site:com.au.

Export and enrich

Confirm a sample in full source, then export the domain list as CSV. SearchWebCode deliberately stops at the list, no bundled CRM, no contact scraping, so you run it against your own enrichment and outreach. The trade-off is cost: a choice of pay-as-you-go per search or Research/Pro subscriptions, with current prices and allowances on the pricing page. If you'd rather a catalogued directory with company data attached, that's what tools like BuiltWith sell; this is the direct-from-source, build-it-yourself route.

Count examples use retained query samples from 2026-10-14. Samples describe stored source from the current index; candidate bounds, estimates and exact matches have different meanings. Methods and author information.

Frequently asked questions

How is this better than a technographics database?

A footprint search checks stored source from the latest quarterly index. Inspect the source capture and query date when judging freshness. You control the exact 'uses X, not Y' logic and export the raw domains.

Can I find companies using one tool but not a competitor?

Yes, that's the switch-target query: footprint of tool A with a minus-excluded footprint of tool B, e.g. WooCommerce stores not on Stripe.

Do I get contact data?

No, SearchWebCode returns domains and source, not contacts. Export the list and run it through your own enrichment. That keeps it separate from contact-data enrichment.
