Wappalyzer

Overview

Wappalyzer is a technographic data and prospecting platform that identifies the technologies behind websites. It is best suited to teams that can turn those signals into sales, marketing, strategy or security actions; for occasional lookups, its paid plans are difficult to justify.

Its combination of technology detection, prospecting tools and integrations is broader than a simple site checker, but the free monthly allowance is small and paid-plan credits expire.

Key features

Technology detection and bulk lookup

Wappalyzer tracks thousands of technologies across millions of websites, identifying them through public signals such as HTML, scripts, headers, cookies and other fingerprints. A CSV or TXT upload can contain up to 100,000 URLs, making the service relevant to larger market scans as well as individual checks. The trade-off is that live results count as five lookups each; cached results were verified within the last 30 days and may suit work that does not need the freshest result.

Prospecting and APIs

Technology-targeted lead lists, company and people search, intent signals, email finding, phone numbers and CRM sync make Wappalyzer a prospecting tool as well as a detection service. Its APIs cover technology lookup, lead lists, subdomain discovery and email verification. That breadth is useful when technology signals belong in an existing sales workflow; it is more than a casual user needs just to identify a site's stack.

Extensions, integrations and MCP

Official apps include Chrome, Firefox, Edge and Safari, plus Salesforce, HubSpot, Pipedrive, Gmail, Pabbly, Zapier, Make and iPhone. The hosted MCP server offers website lookup, subdomain discovery and credit-balance tools, and is read-only. The browser extension performs basic detection locally, while settings allow users to disable sharing of limited website-level data.

Privacy and data use

Wappalyzer says it uses reasonable technical and organizational measures to protect personal information. Its terms restrict users from sublicensing, reselling, publishing, embedding the data in a customer-facing product or otherwise sharing it without written permission. That matters for agencies, data vendors and product teams planning to redistribute enriched results.

Pricing

The free plan costs nothing and includes 50 technology lookups per month, 50 email verifications per month, five website alerts and free sample lead lists. It is a useful way to test the workflow, but the lookup allowance can be consumed quickly, particularly because live results count five times.

Pro costs $250 a month, billed monthly, for one user, two lead-list technology targets, 5,000 technology lookups and 5,000 email verifications. It fits a solo operator with defined prospecting needs, but the single seat and limited target count constrain team use.

Business costs $450 a month, billed monthly, for five users, unlimited lead-list technology targets, 20,000 technology lookups, 20,000 email verifications and 20,000 API credits. It is the more practical team tier where multiple users and API work justify the jump from Pro.

Enterprise costs $850 a month, billed monthly, and includes 25 or more users, unlimited lead-list targets, 200,000 or more technology lookups, email verifications and API credits, dedicated support and custom terms. It is aimed at larger teams with substantial usage rather than buyers seeking a low-cost lookup tool.

API credits included in plans expire after 60 days; credits bought in bundles expire after 365 days. Users should match purchase volume to expected activity rather than assume unused plan credits will roll over. The Enterprise plan is the only one that includes dedicated support and custom terms.

Platforms

Wappalyzer supports Android, iOS, web, APIs, browser extensions and self-hosted use. Its broad platform and integration coverage gives teams several ways to bring technology data into existing work, though the value depends on whether those workflows need prospecting and enrichment alongside detection.

Who it's for

Wappalyzer is built for sales, marketing, operations, strategy, partnerships and security teams that act on technology signals. It is a stronger fit for recurring prospect research, enrichment or monitoring than for a buyer who only needs occasional website checks. Teams that plan to pass its data on to customers should first account for the restrictions on redistribution.

Pros and cons

• Pros: Tracks thousands of technologies across millions of websites, with bulk analysis for up to 100,000 URLs.
• Pros: Combines technology lookup with lead lists, intent signals, contact tools, APIs and CRM integrations, supporting prospecting workflows beyond site identification.
• Pros: Browser-extension detection is local for basic use, and users can disable sharing of limited website-level data in settings.
• Cons: The free tier allows only 50 technology lookups monthly, and live results consume five lookups each.
• Cons: Pro starts at $250 a month for one user, while plan-included API credits expire after 60 days.
• Cons: Data cannot be redistributed or embedded in a customer-facing product without written permission, limiting some commercial use cases.

Alternatives

BuiltWith is worth considering when a free allowance of 10 detailed lookups per day or an Advanced plan at $144 a year better suits a lookup-focused need.

B2BEnrich is an alternative for buyers seeking person and company enrichment, with a free plan of 50 monthly credits and a Starter plan at $49 a month.

BuyerCaddy is another prospecting option, with a Forever Free plan that includes 1,000 tokens and single-user access.

Grizz Technographics offers a free sample with limited technology-stack and company data, making it an alternative to consider for sample-data needs.

Pursued.io is an alternative with a free plan of 50 credits for one team member and a Starter plan of 500 credits for three members.

StackDetect has a free plan with 50 technology lookups per month and free sample lead lists.

TechnologyChecker offers 100 free monthly lookups, six months of historical data, single-result CSV export and basic company enrichment; its Pro plan costs $89 a month.

Bloomberry is an alternative for API access, with a 199.00 USD monthly starter plan covering all vendors and endpoints, 6,633 API credits and email support, but no app access.

Verdict

Choose Wappalyzer if your team needs technology-based prospecting and enrichment at meaningful volume, and will use its APIs or integrations to act on the results. Its detection coverage and workflow breadth are compelling, but the small free quota, high entry price and credit expiry make it a poor fit for occasional lookups or buyers who need to redistribute the data.
