BuiltWith vs Wappalyzer: Pricing, Data & Which to Choose (2026)

BuiltWith and Wappalyzer are the two best-known names in website technology detection. Both tell you what a site runs on, both sell lead lists of companies using a given technology, and both charge serious money once you go past single lookups.

But they are built for different buyers. This guide compares them on pricing, data coverage, lead generation, and API access, using each vendor's published plans as of October 2026.

Quick verdict

• Choose BuiltWith if you need the deepest historical data, market-share research, or spend and revenue estimates, and your budget starts around $295/month.
• Choose Wappalyzer if you mainly want a clean browser extension, CRM enrichment, and verified emails in one place, starting at $250/month.
• Choose neither if you are a small team or agency that just needs fresh lead lists by technology without a $250+ monthly commitment. TechPeeker covers the core of both for less (more below).

BuiltWith vs Wappalyzer at a glance

What is BuiltWith?

BuiltWith is an Australian technology-profiling company that crawls the web much like a search engine does. It reports tracking more than 127,000 technologies across roughly 492 million domains, with usage history going back over 18 years.

Its strength is scale and depth. Beyond lead lists, BuiltWith sells market-share reports, technology spend estimates, ecommerce revenue estimates, and "predictive leads" that flag companies about to switch platforms. It is popular with enterprise sales teams, investors, and market researchers.

The trade-off is price and complexity. The interface is dense, and the Basic plan limits you to lists for just two technologies.

What is Wappalyzer?

Wappalyzer started as an open-source browser extension and is still best known for it. Click the icon on any site and you see its CMS, analytics, ecommerce platform, frameworks, and more in seconds.

The paid product builds on that with lead lists, bulk technology lookups, email verification, website change alerts, and CRM enrichment. Its pitch is a cleaner, prospecting-focused workflow rather than BuiltWith's research-heavy toolkit.

The trade-off is depth. Wappalyzer offers far less historical and market-share data, and its included API credits expire after 60 days.

Pricing: BuiltWith vs Wappalyzer

Wappalyzer is cheaper at every tier, by about $45 to $145 a month. The bigger difference is what each tier unlocks.

BuiltWith pricing

Yearly billing cuts this by about 17%. BuiltWith also sells an Advanced add-on for detailed single-site lookups, and a minimum term of one month applies even if you only need a one-off report.

Wappalyzer pricing

Annual billing saves 17%. Note that API credits bundled with a plan expire after 60 days, so unused credits do not roll over for long.

Which is better value?

At entry level the two are close: both cap lead lists at two technologies, and the $45 gap rarely decides it. At the mid tier, Wappalyzer Business gives five seats for $450 while BuiltWith Pro gives one seat for $495. For a team, Wappalyzer is the clear value pick. For a single analyst who needs history and market data, BuiltWith Pro earns its premium.

Data coverage, accuracy and freshness

BuiltWith wins on coverage; Wappalyzer is usually cleaner on what it does detect.

Coverage. BuiltWith's database is enormous, with over 127,000 technologies tracked. That includes long-tail items like individual tracking pixels, CDNs, and SSL providers. Wappalyzer tracks far fewer technologies but focuses on the ones sales teams actually filter by: CMS, ecommerce platforms, analytics, marketing automation, payment tools, and frameworks.

Accuracy. Both detect technologies from page code, scripts, headers, and cookies. Both can show false positives, such as a technology that was removed but still lingers in old pages. BuiltWith's long history helps here: it shows when a technology was first and last detected, which tells you whether a site still uses it.

Freshness. BuiltWith says it updates its index weekly. Wappalyzer runs a live lookup when you check a single site, so single-site results are current, while its lead-list data depends on its own crawl schedule. For bulk lists from either tool, expect some stale rows, and check a sample before a big campaign.

Lead generation and exports

Both tools let you build a list like "every Shopify store using Klaviyo in Germany" and export it to CSV. The differences are in filters, contact data, and limits.

BuiltWith is stronger for account selection: spend and revenue estimates let you rank prospects by size before you reach out.

Wappalyzer is stronger for outreach readiness: email verification is built in, so fewer bounces when you load a list into your sequencer.

Neither is cheap if lead lists are all you want. Both lock lists across more than two technologies behind the $450 to $495 tier. If you mainly prospect ecommerce stores, our guide to finding Shopify stores using a specific app shows a cheaper workflow.

Browser extension, API and integrations

Browser extension. Wappalyzer's extension is the better day-to-day tool: fast, clean, and grouped by category. BuiltWith's extension works but sends you to its website for the full profile. Both are free.

API. Both offer APIs for technology lookups, list building, and enrichment. BuiltWith has the broader API catalog, including trends, relationships between domains, and AI-agent tooling. Wappalyzer's API is simpler to start with, but plan credits expire after 60 days, which hurts if your usage is uneven.

Integrations. BuiltWith covers more enterprise CRMs, including Microsoft Dynamics 365, Pardot, and Zoho. Wappalyzer covers the common startup stack of HubSpot, Salesforce, Pipedrive, and Zapier.

BuiltWith or Wappalyzer: which should you choose?

A cheaper option that covers both: TechPeeker

If you need technology-based lead lists but not BuiltWith's 18 years of history or Wappalyzer's enterprise seats, TechPeeker does the core job for a fraction of the price.

What you get:

• Unlimited technology lists on every paid plan, where both rivals cap entry plans at two technologies.
• Free detectors for any site's tech stack, CMS, Shopify theme and Shopify apps.
• Ready-made lead sources such as ecommerce leads and Shopify store lists.
• An API for enrichment and automation, documented in our API docs.

The honest trade-off: TechPeeker tracks 800+ technologies across 17M+ websites, focused on the platforms and tools sales teams filter by most. If you need the long tail of 127,000 technologies or decades of history, BuiltWith is still the better fit.
