# CMS Detector — What CMS Is This Website Using?

**Use case:** 

Find out which CMS any website runs on: WordPress, Contentful, Contentstack, Sanity, HubSpot CMS, Webflow, Wix, Squarespace, Shopify and hundreds more, detected from the live site. Paste one domain or a whole list and get the CMS, ecommerce platform and page builder in clean columns. Sites that cannot be detected are free.

## Input

```json
{
  "domains": [
    "techcrunch.com",

  ],
  "onlyDomainsUsing": [],
  "categories": [
    "CMS",
    "Blogs",
    "Page builders",
    "Ecommerce"

## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/jesting_grass/tech-stack-detector.md

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).
