Wappalyzer

Overview

Wappalyzer turns the technologies behind websites into data for prospecting, record enrichment and market monitoring. It is best suited to sales, marketing and research teams that can put technology signals to work across their workflows. Its breadth reaches beyond website lookup, but the paid entry point and credit rules make cost worth weighing against expected use.

Key features

Technology detection and bulk analysis

Wappalyzer detects thousands of technologies across millions of websites from public signals such as HTML, scripts, headers and cookies. You can also upload a CSV or TXT file with up to 100,000 URLs, a useful scale for market scans or prospect lists. The trade-off is that live results count as five lookups each; cached results are verified within the last 30 days and may be a better fit when immediate freshness is not essential.

Prospecting and APIs

Technology-targeted lead lists, company and people search, intent signals, email finding, phone numbers and CRM sync make Wappalyzer more than a detection tool. Its APIs cover technology lookup, lead lists, subdomain discovery and email verification. That combination suits teams building technology signals into prospecting and enrichment processes, but is more than needed for occasional manual lookups.

Apps and integrations

Official apps cover 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, but is read-only. The browser extension performs basic detection locally, and users can disable sharing of limited website-level data in its settings.

Data use and credits

Credits included in plans expire after 60 days; bundle-purchased credits expire after 365 days. That distinction matters for teams whose usage is irregular. Wappalyzer's terms also prohibit sublicensing, reselling, publishing, embedding its data in a customer-facing product or otherwise sharing it without written permission, so it is not a straightforward source for redistributable data.

Pricing

Wappalyzer has a free plan and a free trial. Paid plans are billed monthly, with the listed starting rate at $250 a month.

Pro is for an individual user who can work within two lead-list targets and 5,000 lookups and verifications. Business adds seats, targets and substantially larger quotas for a small team; Enterprise raises the scale further and adds dedicated support and custom terms. Live results consuming five lookups each can make the paid quotas go faster than headline lookup counts suggest. API credits included in plans expire after 60 days, so unused monthly allocation does not carry indefinitely.

Platforms

Wappalyzer supports Android, iOS, web, API, browser extensions and self-hosted use. Its browser apps cover Chrome, Firefox, Edge and Safari.

Who it's for

Wappalyzer is built for sales, marketing, operations, strategy, partnerships and security teams that make decisions or take action based on technology signals. Its prospecting and CRM features favor teams integrating those signals into workflows; its data-sharing restrictions make it a poor fit for products that need to redistribute or embed the data for customers without written permission. Wappalyzer says it uses reasonable technical and organizational measures designed to protect personal information.

Pros and cons

Pros: Broad detection and bulk uploads of up to 100,000 URLs support both individual research and large scans.

Pros: APIs, intent signals, lead lists and contact-oriented tools connect technographic data to prospecting and enrichment.

Pros: Browser extension detection runs locally for basic identification, with an option to disable sharing of limited website-level data.

Cons: Paid plans start at $250 a month, a high starting commitment for occasional lookup needs.

Cons: Live results count as five lookups, and plan credits expire after 60 days, limiting the value of unused allocation.

Cons: Restrictions on sharing Wappalyzer data rule out many redistribution and customer-facing embedding uses without written permission.

Alternatives

Choose BuiltWith if its free allowance of 10 detailed lookups per day is a better match for a smaller volume of manual checks, or if its Advanced plan's unlimited detailed lookups and one-year minimum suits your requirements. Clay is worth considering when enrichment workflows are the priority: its free plan includes 500 actions per month, 100 data credits and unlimited seats and tables, but caps tables at 200 rows. For API-focused technology data, compare Coresignal, which has a free tier with 2,000 credits, a 5 req/s limit, a seven-day trial and email support. PredictLeads is another API-oriented option, with free usage tiers tied to API-call ranges. TheirStack offers a free monthly allocation of 50 company credits and 200 API credits plus search-result pages, making it a possible starting point for teams testing company discovery. Explorium offers a 100-credit trial valid for 90 days, while Enigma has a free console tier for viewing, search and live summaries. Olostep Company Data API provides a trial with 500 successful requests, including JavaScript-rendered requests and residential IP addresses, though with low rate limits.

Verdict

Choose Wappalyzer if your team needs technographic signals for prospecting or enrichment at meaningful volume, and will use its APIs, lead tools or integrations. Its detection coverage and 100,000-URL bulk analysis are the strongest reasons to choose it. Look elsewhere if you only need occasional lookups, must preserve unused credits, or plan to share its data with customers.
