BuiltWith Review — Honest Pros, Cons & Pricing (2026)

Category: Website technology lookup and analytics

Also known as: builtwith.

Overview

BuiltWith scans websites and identifies every technology they use, from CMS and email platforms to analytics tools and payment processors. Enter any domain and BuiltWith shows you the full technology stack. For cold email prospecting, this is useful for technology displacement campaigns. If you sell an email marketing platform, you can use BuiltWith to find every company using a specific competitor, then craft cold emails that speak directly to the limitations of that competitor. The free tier lets you look up individual domains. The Pro plan at $295/mo provides bulk lookups, technology adoption trends, and lead lists filtered by technology usage.
