Wappalyzer shows which technologies a website is built with, from its CMS and ecommerce platform to analytics, chat and marketing tools. Sales and marketing teams use that data to find companies that run a specific tool, enrich CRM records and spot when a prospect changes its stack.
Elbert Alias founded Wappalyzer in 2008. It started as a browser extension for developers and now positions itself as a technographics product for sales and go-to-market teams.
Who is Wappalyzer for?
Wappalyzer fits teams whose ideal customer is defined by the software a company uses. A Shopify app builder can list stores on Shopify. An agency can find sites on an outdated CMS. A partnerships manager can find companies that use a complementary platform. Security teams also use it to see technologies and versions on external websites.
If you only want to check the occasional website, the free account and browser extension are enough. Teams that prospect at scale need a paid plan for lead lists, APIs and CRM integrations.
What are Wappalyzer's main features?
Technology lookup
Enter a URL and Wappalyzer lists the technologies it detects, with company and contact details where available. You can also analyze a list of domains in bulk or call the lookup through the API.
Lead lists
This is the core paid product. You choose a technology or keyword, filter by market, traffic level and country, and export a list of websites with company and contact data. Wappalyzer lets you review a free sample before you buy. For background on building a pipeline this way, see our guide to lead generation.
Website alerts
Alerts watch competitor, prospect and customer websites and tell you when they add a new tool or migrate to another platform. That change can be a useful moment for outreach.
Browser extension and apps
The free browser extension shows the technology behind any page you visit. With Plus you also see company and contact information in the extension and the mobile app.

When should you choose an alternative?

- You already have target companies and only need email addresses. An email finder such as Hunter is cheaper.
