How can I find domains using a specific technology stack?

Finding Domains Using a Specific Technology Stack

Using Built With

BuiltWith offers a standalone approach:

• Select your desired technology stack
• Receive a ready-made list of websites using that stack

Using Clay

Clay takes the opposite approach:

• You provide an existing list of domains
• Clay validates which sites use your specified technology stack

Key Difference

• BuiltWith: Technology stack → generates domain list
• Clay: Domain list → filters by technology stack

Finding Domains by Technology Stack

Tool Limitations:

• BuiltWith can only validate technology on domains you already have—it cannot generate a list of domains based on specific technologies
• BuiltWith requires an input domain to function, so there is no workaround for discovery

Solution:

• HG Insights is the only provider in Clay that supports discovering domains filtered by technology stack
• Use HG Insights to find lists of domains using specific technologies (e.g., HubSpot, etc.)
