A BuiltWith alternative
BuiltWith is the reference for website technology data, and its lead lists are priced for large sales teams. TechLookup covers the everyday needs, looking a site up and finding websites that use a technology, at a fraction of the cost. Here is what that means in practice.
What is the same
Both tell you what a website is built with: CMS, frameworks, analytics, hosting, CDN, payment and marketing tools, with versions where exposed. Both let you turn that around and find the websites using a given technology, filter them and export the list. Both keep a history, so you can see when a technology first appeared on a site.
What is different
| TechLookup | BuiltWith | |
|---|---|---|
| Single website lookup | Free: 5 a day without an account, more with a free one | Free |
| Lists of websites by technology | From $19 a month | From a few hundred dollars a month at the time of writing |
| Index | The most visited million domains, re-scanned monthly, plus every site anyone looks up | Far larger, with data reaching back many years |
| History | First and last seen dates from our first crawl in September 2026 onwards | Long-running historical data |
| How a site is scanned | A real browser loads the home page, so client-side frameworks are seen | Its own crawler |
| Contact details | Publicly listed business emails and social links, on the Pro plan | Extensive contact and firmographic data |
BuiltWith's features and prices are theirs to describe; check builtwith.com for the current offer. This page describes TechLookup honestly rather than claiming to match everything a much larger product does.
Who TechLookup suits
Freelancers, agencies and small teams who need to check a site's stack before a call, size up a competitor, or build a list of a few thousand websites using the platform they serve. If your work needs millions of records, years of history or firmographic enrichment, BuiltWith remains the tool for that.
