Build technographic lead lists from JavaScript fingerprints

By the SearchWebCode team · Published April 28, 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. You pay per search, not per month, 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. Because every 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: pay-as-you-go per search instead of a monthly platform fee, which suits periodic list-building far better than a subscription. 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.

Frequently asked questions

How is this better than a technographics database?

A footprint search reflects what sites ship right now, verified against live source, rather than a periodically-refreshed database. 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 usage-priced instead of a monthly platform fee.
