Features

Everything you need to turn tech stacks into pipeline

From tech-stack lead search to AI-drafted outreach — every scan makes the lead database smarter.

Lead Generation

"Every site using WordPress + WooCommerce but not Cloudflare." Search the scan database by tech stack and export the list as CSV.

ICP Lead Engine

Save your ideal customer profile once. We keep matching new domains against it and alert you the moment fresh prospects appear.

Tech Stack X-Ray

Identify every framework, CMS, CDN, analytics tool, and ad network powering any website. Wappalyzer-grade accuracy, free.

AI Sales Outreach

Turn any scan into an outreach angle: AI cold-email drafts, sales briefs, and gap analysis grounded in real scan data.

Competitor Monitoring

Watch competitors for tech stack changes, downtime, and security regressions. Get alerts via email or webhook.

Security & SEO Audits

A-F security grade, CVE cross-referencing, Core Web Vitals, and on-page SEO audits — perfect ammunition for your pitch.

How It Works

From tech stack to lead list in three steps

1

Describe your ideal customer

Pick the technologies they use — and the ones they don't. "Shopify stores without a review app." "Sites still on jQuery 1.x."

2

We find matching domains

Search a continuously growing database of live-scanned websites. Every match is verified by an actual scan, not a stale crawl.

3

Export & reach out

Download the list as CSV, generate AI cold-email drafts from each prospect's real stack, and get alerted when new matches appear.

Frequently Asked Questions

SiteIntelica turns technology stacks into lead lists. Tell it which technologies your ideal customer uses (or lacks) and it returns matching websites — verified by live scans, exportable as CSV, and continuously refreshed. The free X-Ray scanner that powers it also lets you analyze any single website's tech, security, and SEO in seconds.
BuiltWith sells lead lists starting at $295/month, built from crawls that are often months stale — full of dead sites and removed technologies. SiteIntelica leads come from live scans, so every match reflects what the site runs right now, at a fraction of the price. Wappalyzer's extension tells you about one site at a time; we tell you every site that matches your profile.
Every scan feeds the database: free X-ray scans, bulk scans, and our own continuous seeding of new domains. The corpus grows daily, and the ICP Lead Engine alerts you when newly scanned domains match your saved profiles.
Yes! The free tier gives you 5 full X-ray scans per day plus a lead-search preview that shows how many domains match your criteria. Pro unlocks full lead lists with CSV export; Business adds the self-updating ICP Lead Engine.
