See what any website is built with

Sockt reads a site's headers, scripts, cookies and meta tags, sorts the technologies it finds into categories and records where and when it saw each one. It has analysed 28,895,742 websites so far. Search them by technology and turn the results into lead lists.

5,859 technologies found on 28,895,742 sites. Where the data comes from

Every detection shows where we found it

A lookup groups a site's technologies by category. Each one shows how it was found, the date we first observed it, the date we last saw it and a confidence. In Raq.com you can open the supporting evidence. These observations come from the current index:

page structure: Cart Functionality on shopify.com
scripts: Shopify on shopify.com
HTTP headers: Cloudflare on shopify.com
HTTP headers: HSTS on shopify.com

A capture that fails or a site that blocks a check never removes a technology. Only a newer successful check of the same site can.

Build lead lists from technology filters

Combine technologies with AND, OR and NOT, narrow by country, TLD, industry or site rank, and get one row per domain with duplicates removed. Download the list as CSV or add it to Raq.com CRM.

See which sites use a technology

Every technology has a page with the number of sites using it, the top sites by rank, the TLDs they sit on, the versions we found and the technologies most often used alongside it.

How alerts work
API and MCP

Enrich your own records from code, or let a Raq.com agent build a list and add it to CRM.
API and MCP reference

Get told when a site changes its technology

Add domains to a watchlist and Sockt checks them again on a schedule. When a technology appears or disappears you get an alert by email and in Raq.com.

A blocked or failed check marks the domain unknown until the next good check, so a temporary block is not mistaken for a removal.

Watch 100 domains on Basic, 500 on Pro and 2,500 on Team.

Use the same data from the API and MCP

Look up domains and run technology searches from your own code with a Raq.com API token. Raq.com AI agents get the same lookups and searches as MCP tools, so an agent can build a list and add it to CRM for you.

The web app, API and MCP draw on one shared quota.

sockt_add_monitors: Watch up to 1,000 domains for technology changes. Existing domains are skipped; plan limits apply.
sockt_assign_seat: Give an account member a paid Sockt seat. Owner/admin only; seat limits apply.
sockt_cancel_plan: Cancel the Sockt plan at the end of its paid period. Owner/admin only.

SocktBot says who it is and follows your robots.txt

Every fact in Sockt carries the source and date it came from. When Sockt fetches pages itself, SocktBot collects that evidence openly, with limits on how often and how much it fetches.
