Look up a domain or find accounts by public tech stack

Paste a URL, a CSV of domains, or a stack combo such as Shopify + Klaviyo. Leadify reads public fingerprints and returns a structured profile or a matching company list. Export as CSV.

When your reps have to qualify a lead, knowing the stack changes everything. Are they on Shopify or WooCommerce? Klaviyo or Mailchimp? Custom-built or off-the-shelf? Generic technographic vendors lag months behind, and free tools cap requests fast. Leadify detects stack on demand, in your existing workflow, so the answer is always next to the lead, not in a separate tab.

How it works

Send a domain or list — Pass one URL or a CSV of domains. Leadify queues detection and processes in parallel.
Detect on the live site — We render the page, scan script tags, headers, cookies, and other fingerprints to identify tools in use.
Categorize results — Tools are grouped by category — CMS, e-commerce, analytics, marketing, payments, hosting — for clean filtering.
Return structured profile — You get a per-domain stack profile with confidence scores, ready to filter, score, and export as CSV.

Questions and answers

How accurate is detection?

We score every detection individually. High-confidence detections are above 95 percent in our customer cohorts; medium-confidence ones are flagged for human review.

How fresh is the detection?

We detect live at request time, so results reflect the current state of the site, not a months-old database.

Can you detect tools that hide their fingerprint?

Some tools intentionally remove their fingerprint. We flag uncertain detections rather than guess. Combine with traffic and content signals where it helps.

Is this GDPR safe?

Yes. Detection runs on publicly served pages, the same way a browser sees them, and stores no personal data.
