Why Technographics Are a Targeting Superpower
Technographic data — the tools a company runs — is one of the highest-intent B2B signals available. It tells you fit ("they use Klaviyo, so they sell DTC"), timing ("they just added Stripe"), and competitive displacement ("they're on a rival you beat"). The catch is that a tech signal only earns revenue when it reaches the right buyer. So the tools split into two camps:
- Data tools (BuiltWith, Wappalyzer, Ful.io, W3Techs) — identify the stack and give you a list or API to act on elsewhere.
- Targeting-to-outreach (DitLead) — apply the tech filter to a contact database and run the campaign in the same platform.
Which you need depends on whether your goal is research or pipeline.
1. DitLead
Best for turning tech signals into pipeline

The other tools tell you what a website is built with. DitLead's technology lookup applies tech-stack filters across a 700M+ contact database and feeds the matches straight into a multichannel campaign — so 'companies using Shopify and Klaviyo' becomes verified contacts, personalized copy and a live sequence, without exporting to a separate sender. Technographic targeting as an outreach motion, not just a data export.
Best for: Sales teams that want technographic targeting to drive real campaigns, not just research.
2. BuiltWith
Best technographic coverage

BuiltWith is the category standard — free single-site lookups and the deepest technology coverage (115,000+ technologies), with technographic lead lists from ~$295/month (Pro ~$495). Unmatched for research and list-building. It's a data tool, though: you export a list and take it to a separate outreach platform.
Best for: Researchers and teams who need the widest, deepest tech-stack data.
3. Wappalyzer
Best profiler + enrichment API

Wappalyzer is the popular, fast technology profiler, with lead lists, enrichment and clean APIs on a per-lookup/credit model. Great if you're enriching records inside your own product or pipeline — but, like BuiltWith, it identifies the stack and hands the data off; sending happens elsewhere.
Best for: Teams wanting tech detection as an API or enrichment layer.
4. Ful.io
Best lightweight profiler

Ful.io is a clean technology profiler and lookup service for analyzing any website's stack, with an approachable interface and API. A solid, simpler alternative to BuiltWith for straightforward tech checks — data-only, no outreach.
Best for: Smaller teams wanting quick, affordable tech-stack checks.
5. W3Techs
Best for market-share research
W3Techs identifies the technologies behind a site (CMS, server, language, hosting) and is the go-to for technology market-share surveys and trends. Excellent for analysts and research; it's not built for building targeted lead lists or running outreach.
Best for: Analysts studying technology adoption and market share.
6. Wappalyzer/BuiltWith browser extensions
Best free quick check
Both BuiltWith and Wappalyzer ship free browser extensions that reveal a single site's stack in a click. Perfect for ad-hoc 'what is this built with' curiosity — but single-site lookups don't scale into targeted prospect lists or campaigns.
Best for: Anyone needing an instant, free, one-off tech-stack check.
The Bottom Line
For pure technographic research and the deepest coverage, BuiltWith is the benchmark and Wappalyzer the best API. But every data tool leaves you with a list and a second problem: actually reaching those companies. DitLead's technology lookup closes that gap — tech-stack filters over 700M+ contacts, flowing into email, LinkedIn and call sequences with warmup attached.
