# Find which CMS a list of websites uses

**Use case:** 

Paste a list of public website URLs and see which CMS or site builder each one runs on, with the evidence for every finding (header, generator tag or file that matched). The same scan also lists JavaScript frameworks, analytics, CDN, hosting and web server.

## Input

```json
{
  "urls": [
    "https://www.python.org/"
  ],
  "minConfidence": 50,
  "maxPagesPerSite": 1,
  "probeWellKnownPaths": true,
  "includeEvidence": true,
  "timeoutSecs": 15,
  "maxConcurrency": 3,
  "ignoreRobotsTxt": false,
  "overrideDomainStop": false,
  "robotsOwnershipAttestation": ""
}
```

## Output

```json
{
  "index": {
    "label": "Index"
  },
  "url": {
    "label": "Url"
  },
  "status": {
    "label": "Status"
  },
  "technologies": {
    "label": "Technologies"
  },
  "pagesScanned": {
    "label": "Pages scanned"
  },
  "probes": {
    "label": "Probes"
  }
}
```

## 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/luxe_tasks/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`).
