Overview

Wappalyzer turns public website signals into technology profiles for prospecting, record enrichment and tracking changes in a market. It is best suited to revenue, research and security teams that can put those signals to work. Its combination of detection and contact tools is broad, but the paid entry point makes it a substantial commitment for occasional lookups.

It identifies thousands of technologies across millions of websites from clues such as HTML, scripts, headers and cookies. Founded in 2008 and headquartered in Australia, Wappalyzer also offers company and people search, technology intent signals, email finding, phone numbers and CRM sync.

Key features

Technology lookup and bulk analysis

Teams can analyze a site or upload a CSV or TXT file with up to 100,000 URLs. That batch capacity suits prospect lists and market scans, but live results count as five lookups each. Cached results are verified within the last 30 days, so they may stretch a quota when current detection is not essential.

Prospecting and APIs

Technology-targeted lead lists, company and people search, intent signals and contact discovery make Wappalyzer more than a site-identification utility. APIs cover technology lookup, lead lists, subdomain discovery and email verification. These functions fit teams integrating technographic signals into an existing sales workflow; they are harder to justify for someone who only wants to identify the occasional site's software.

Apps, integrations and MCP

Official apps cover Chrome, Firefox, Edge and Safari, as well as Salesforce, HubSpot, Pipedrive, Gmail, Pabbly, Zapier, Make and iPhone. The hosted MCP server provides website lookup, subdomain discovery and credit-balance tools, and is read-only. The range offers several ways to bring the data into a workflow, while the read-only MCP scope is not suited to teams expecting it to take actions.

Privacy and data use

The browser extension performs basic detection locally, and settings let users disable sharing of limited website-level data. Wappalyzer says it uses reasonable technical and organizational measures 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 significant constraint for agencies and product builders.

Pricing

Wappalyzer is freemium, with paid plans billed monthly. The free tier is a useful way to try the workflow, but its small lookup and verification allowances are not a substitute for sustained prospecting.

Free — 0.00 USD per free: 50 technology lookups and 50 email verifications per month, five website alerts and free sample lead lists. Best for initial evaluation or very light use.
Pro — 250.00 USD per month: one user, two lead-list technology targets, 5,000 technology lookups and 5,000 email verifications. It suits an individual operator with a defined target list, but has no included API credits in the stated plan.
Business — 450.00 USD per month: 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 tier for a small team running broader searches and integrations.
Enterprise — 850.00 USD per month: 25 or more users, unlimited lead-list technology targets, 200,000 or more technology lookups, email verifications and API credits, plus dedicated support and custom terms. It is aimed at larger teams with substantial volume and support needs.

API credits included in plans expire after 60 days; purchased bundles expire after 365 days. Live results consume five lookups apiece, so headline lookup allowances can go faster when fresh results matter. Check intended data use against the sharing restrictions before building customer-facing services around Wappalyzer output.

Platforms

Wappalyzer is available on Android, iOS, the web, through APIs and browser extensions, and as a self-hosted option. The platform range supports both individual browser-based research and integration-oriented use.

Who it's for

Sales and marketing teams can use technology signals to shape prospect lists and enrich records; operations and strategy teams can monitor the market; partnerships and security teams can identify technology footprints relevant to their work. The fit is strongest when a team has a recurring workflow and enough volume to justify paid quotas. A casual user or a business that needs to redistribute the resulting data should look elsewhere or secure written permission first.

Pros and cons

Pros: Broad coverage across thousands of technologies and millions of sites gives teams a substantial base for technographic research.
Pros: Bulk analysis accepts up to 100,000 URLs, useful for large prospect and market scans.
Pros: Lead lists, contact tools, APIs and CRM integrations connect detection to prospecting workflows.
Cons: Paid plans start at 250.00 USD per month for one user, a steep starting point for occasional or small-scale use.
Cons: Live results count five times against lookup usage, and included API credits expire after 60 days, so quotas require active management.
Cons: Restrictions on sharing, resale and customer-facing embedding limit commercial redistribution without written permission.

Alternatives

Consider Datanyze if its browser-extension and web access or 90-day Nyze Lite trial better suits an evaluation; its paid plans have no published prices in the supplied plan details. PredictLeads is another freemium, API-oriented option, with web and self-hosted platforms. Choose TechnologyChecker if a lower-cost paid tier and a smaller monthly lookup allowance are a better fit: its free plan includes 100 lookups a month, six months of historical data, CSV export for a single result and basic company enrichment, while Pro is 89.00 USD per month. B2BEnrich may suit teams prioritizing person and company enrichment on a free tier of 50 monthly credits, with Starter at 49.00 USD per month.

Pursued.io offers a free web plan with 50 credits and one team member. TheirStack has a free tier with monthly company and API credits, search-result pages and workspace invitations; its paid API plan is 49.00 USD per month. StackDetect has a free plan with 50 monthly technology lookups and sample lead lists. BuiltWith offers ten detailed lookups per day free and an Advanced plan at 144.00 USD per year with a one-year minimum duration.

Verdict

Wappalyzer is a strong choice for teams that need technology-based prospecting and enrichment at meaningful scale, especially when APIs and CRM integrations can put the data straight into existing workflows. The main reasons to look elsewhere are its $250 monthly paid entry point, expiring credits and strict limits on redistribution. It is most worthwhile when a team can consistently use the quotas and has permission to use the data as intended.
