Overview

Wappalyzer converts public clues about website infrastructure into technographic data for prospecting, record enrichment and market monitoring. It is best suited to teams that can use technology signals to guide sales, research or security work; occasional site lookups may not justify the cost of its paid plans.

Its coverage spans thousands of technologies across millions of websites, with detection based on signals such as HTML, scripts, headers and cookies. Founded in 2008 and headquartered in Australia, Wappalyzer combines that core lookup with lead and contact tools.

Key features

Technology lookup and bulk analysis

Teams can check a website individually or upload a CSV or TXT file containing up to 100,000 URLs. That scale makes Wappalyzer useful for broad market scans, but live results count as five lookups each. Cached results are verified within the last 30 days, so they can stretch lookup allowances when the freshest result is not essential.

Prospecting tools and APIs

Technology-targeted lead lists, company and people search, intent signals, email finding, phone numbers and CRM sync make Wappalyzer more than a site-identification tool. Its APIs cover technology lookup, lead lists, subdomain discovery and email verification. This breadth is valuable for teams incorporating technographic signals into prospecting; it is harder to justify if the need is limited to occasional identification.

Extensions, integrations and MCP

Official apps include extensions for Chrome, Firefox, Edge and Safari, plus connections to Salesforce, HubSpot, Pipedrive, Gmail, Pabbly, Zapier and Make, as well as an iPhone app. The hosted MCP server supports website lookup, subdomain discovery and credit-balance checks, but is read-only. The browser extension performs basic detection locally, and settings can disable sharing of limited website-level data.

Credits, privacy and data use

API credits included with plans expire after 60 days; credits bought in bundles last 365 days. Wappalyzer says it uses reasonable technical and organizational measures designed to protect personal information. Its terms prohibit sublicensing, reselling, publishing, embedding data in a customer-facing product or otherwise sharing it without written permission, a material constraint for agencies and product builders.

Pricing

Wappalyzer is freemium, with paid plans billed monthly and starting at $250.00 USD per month. The free tier is useful for small-scale evaluation, but its monthly caps are modest for ongoing prospecting.

Free — 0.00 USD per free: 50 technology lookups per month, 50 email verifications per month, five website alerts and free sample lead lists. A reasonable starting point for occasional checks, not a sustained high-volume workflow.
Pro — 250.00 USD per month, billed monthly: one user, two lead-list technology targets, 5,000 technology lookups and 5,000 email verifications. It suits a single prospecting user, but provides no stated API-credit allotment and keeps target selection narrow.
Business — 450.00 USD per month, billed monthly: five users, unlimited lead-list technology targets, 20,000 technology lookups, 20,000 email verifications and 20,000 API credits. This is the more practical step up for a small team needing broader targeting and API use.
Enterprise — 850.00 USD per month, billed monthly: 25 or more users, unlimited lead-list technology targets, 200,000 or more technology lookups, 200,000 or more email verifications, 200,000 or more API credits, dedicated support and custom terms. It is aimed at larger operations that need scale and support.

A free trial is available. Credit expiry matters when demand is uneven: plan-included API credits expire after 60 days, unlike bundle-purchased credits, which expire after 365 days.

Platforms

Wappalyzer supports Android, iOS, web, APIs, browser extensions and self-hosted use. That mix accommodates both in-browser research and workflow or infrastructure integrations.

Who it's for

Wappalyzer is built for sales, marketing, operations, strategy, partnerships and security teams that can act on technology signals. Its broad lookup and prospecting tools make the strongest case for teams doing repeat research or integrating technology data into lead workflows. It is a weaker fit for individuals seeking only occasional lookups, or for businesses that need to redistribute the resulting data without permission.

Pros and cons

Pros: Broad technology coverage and bulk analysis of up to 100,000 URLs support market scans at scale.
Pros: Lead tools, APIs and CRM integrations connect technographic signals to prospecting workflows.
Pros: Local basic extension detection and an option to disable sharing of limited website-level data give users some control over extension data sharing.
Cons: The free plan's 50 monthly technology lookups and 50 email verifications limit sustained use.
Cons: Live results consume five lookups each, and included API credits expire after 60 days.
Cons: Restrictions on sharing Wappalyzer data can rule it out for resale, customer-facing products or other redistribution without written permission.

Verdict

Choose Wappalyzer if your team needs technology-based prospecting or monitoring at meaningful volume and can put its integrations, APIs and lead tools to work. Its coverage and workflow breadth are the main reasons to pay; its lookup economics, credit expiry and strict data-sharing limits are good reasons to look elsewhere when usage is light or redistribution is central.
