Overview

Wappalyzer turns public website signals into technology profiles that teams can use to identify prospects, enrich records and follow market changes. It suits sales and research teams that can act on those signals, but its paid plans start at $250 per user per month, and credits expire.

It covers thousands of technologies across millions of websites, using clues such as HTML, scripts, headers and cookies. Founded in 2008 and headquartered in Australia, Wappalyzer also offers lead and contact tools alongside its core technographic data.

Key features

Technology lookup and bulk analysis

Look up a site individually or upload a CSV or TXT file containing up to 100,000 URLs. That batch size is useful for market scans and prospect lists, though live results consume five lookups apiece. Cached results are verified within the last 30 days, a potentially more economical choice when the latest signals are not essential.

Prospecting tools and APIs

Technology-based lead lists, company and people search, intent signals, email finding, phone numbers and CRM sync extend Wappalyzer beyond a site-identification tool. Its APIs cover technology lookup, lead lists, subdomain discovery and email verification. This breadth suits teams that want to bring technology signals into prospecting workflows; it is less compelling if all you need is occasional identification of a site's software.

Extensions, integrations and MCP

Official apps include 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 browser extension performs basic detection locally; settings let users 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 prohibit sublicensing, reselling, publishing, embedding data in a customer-facing product or otherwise sharing it without written permission. That restriction matters for agencies and product teams planning to redistribute results, even when the underlying work is legitimate prospecting or research.

Pricing

Wappalyzer is freemium, with a free plan and a free trial. The free plan costs 0.00 USD per free and includes 50 technology lookups per month, 50 email verifications per month, five website alerts and free sample lead lists. It is a useful small-scale starting point, but the lookup and verification caps limit sustained prospecting.

Pro costs 250.00 USD per month, billed monthly, for one user, two lead-list technology targets, 5,000 technology lookups and 5,000 email verifications. It fits an individual prospecting workflow, but the single seat and two-target cap make it a narrow option for a team or for broad list-building.

Business costs 450.00 USD per month, billed monthly, and includes 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 tier for a small group building repeatable workflows, though its quotas still call for monitoring at scale.

Enterprise costs 850.00 USD per month, billed monthly, and covers 25+ users, unlimited lead-list technology targets, 200,000+ technology lookups, 200,000+ email verifications and 200,000+ API credits, with dedicated support and custom terms. It is designed for larger deployments, not casual research. API credits included in plans expire after 60 days; credits bought in bundles expire after 365 days, so unused balances are not indefinitely bankable.

Live results counting as five lookups each also means the headline technology quota can go faster than expected. Check the data-sharing terms before using results in work that exposes them to clients or other external audiences.

Platforms

Wappalyzer supports Android, iOS, web, API, browser extensions and self-hosted use. Its browser and CRM integrations give it routes into both individual research and sales workflows.

Who it's for

Sales, marketing, operations, strategy, partnerships and security teams are the clearest fit when technology choices provide a useful signal for targeting, enrichment or monitoring. The free tier suits light exploration; paid plans make more sense when lookup, verification or API volume justifies the monthly cost. Teams that need to share or package the resulting data externally should look elsewhere unless they obtain written permission.

Pros and cons

Pros: Broad coverage across thousands of technologies and millions of websites supports research beyond a small set of popular platforms.
Pros: Bulk analysis accepts up to 100,000 URLs, making large prospect or market lists feasible to process in one upload.
Pros: APIs, CRM integrations and prospecting functions connect technology signals to lead and contact workflows.
Cons: Live results count as five lookups, so the listed technology quota may support fewer live checks than a reader expects.
Cons: Plan credits expire, and the paid entry tier is costly for an individual who needs only occasional lookups.
Cons: Data cannot be republished or embedded in customer-facing products without written permission, restricting some client-service uses.

Alternatives

Sales Prospecting Software, Technographic Data Software, Lead Enrichment Software, Account Enrichment Software and Company Databases are category roundups for comparing tools by workflow.

Clay is a freemium alternative with a free tier offering 500 actions and 100 data credits per month, plus unlimited seats and tables; consider it when those limits and its listed Linux, macOS and web platforms better fit.
BuiltWith offers a free tier with 10 detailed lookups per day and an Advanced plan at 144.00 USD per year, billed with a one-year minimum; consider it for a lower-priced technology-lookup option if that daily allowance is enough.
Salesmotion has a free tier with 100 credits per month, all eight endpoints and three-month credit rollover; consider it if that API access and rollover suit your workload.
Surfe has an Essential plan at 39.00 USD per year, billed annually, including email and mobile find credits and weekly company and people search results; consider it if those contact-finding allowances are the priority.
Factors.ai has a Basic plan listed at 6.00 USD per year with up to 10,000 monthly tracked users, 3,000 companies identified per month and five seats; consider it if those tracking and identification limits match your needs.
Persana AI offers a free tier with 50 credits, 50 emails, five phones and searches of up to 500 people or companies; consider it for a small, no-cost contact-search workload.
Apollo has a free tier with 900 credits per seat per year, granted monthly, two sequences, API access and one intent topic; consider it if those prospecting allowances are a closer fit.
LeadIQ offers a free plan for one user with 50 credits; consider it for a single-user workflow that can stay within that allowance.

Verdict

Wappalyzer is a strong fit for teams that use website technology as a prospecting or market signal and need bulk lookup, APIs and connected sales tools in one workflow. Its broad coverage and 100,000-URL upload ceiling are substantial strengths. Choose another approach if you only need occasional site checks, cannot justify the $250.00 monthly entry price, or need to redistribute data without written permission.
