## Pricing

from $0.45 / 1,000 technology detections

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.
Since this Actor supports Apify Store discounts, the price gets lower the higher subscription plan you have.

## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

Track evidence-backed changes in a supported set of public website technology signals. Every detection includes the public-page evidence that produced it.

### 🎯 What it does

The Actor checks public pages and their robots rules. It recognizes supported CMS, framework, analytics, and infrastructure signatures, then returns a current snapshot or changes after a complete scan.

### 👥 Who it is for

- Agencies monitoring a declared list of client or competitor sites.
- GTM and data teams enriching an owned account list.
- Web teams looking for public migration signals to review.

### 🧾 Input

| Field | Type | Required | Description |
| --- | --- | --- | --- |
| Public website URLs | Array | No | One to fifteen public HTTP(S) pages. Robots rules are checked first. |
| Output mode | Choice | No | `full` returns current evidence. `changesOnly` returns new, added, and removed evidence. |
| Maximum pages this run | Number | No | Limits selected URLs. A capped scan does not update saved state. |

### 📊 Output

| Field | Type | Description |
| --- | --- | --- |
| changeType | String | `SNAPSHOT`, `NEW`, `ADDED`, or `REMOVED`. |
| provider | String | Supported detected provider or technology. |
| category | String | Supported technology category. |
| evidenceType | String | Public evidence source, such as page markup or header. |
| evidenceValue | String | Matched public evidence. |
| confidence | String | `HIGH` or `MEDIUM` confidence for the public signal. |
| targetUrl | URL | Page that produced the record. |

### 💡 Good to know

- Supported signatures include WordPress, Shopify, Webflow, Squarespace, Wix, Next.js, Nuxt, React, Google Analytics, Google Tag Manager, Matomo, Meta Pixel, Cloudflare, and Bootstrap.
- A public signal is not proof of active customer use, purchase intent, or a vendor relationship.
- Failed, blocked, or capped scans do not advance the saved baseline.

### 💰 Pricing

This Actor uses pay per result. Empty runs do not create result charges. Start with a small list of pages and review the evidence.

### ❓ FAQ

**Does it detect every technology?** No. It recognizes the supported signatures listed above.

**Does a signal prove a company uses the product?** No. It is public-page evidence that requires your review.

**Why did a page not produce a result?** It may be blocked by robots rules, unavailable, or contain no supported signal.

**Can I monitor changes?** Yes. Use the same URLs in changes-only mode.

# Actor input Schema

## `targetUrls` (type: `array`):

Public HTTP(S) pages to scan. The Actor requests robots.txt and skips paths that are explicitly disallowed.

## `mode` (type: `string`):

Changes only emits NEW, ADDED, and REMOVED evidence after a complete scan. Full emits the current evidence-backed snapshot.

## `maxPages` (type: `integer`):

Bound this run to a small public URL set. A capped run never advances monitor state.

## Actor input object example

```json
{
  "targetUrls": [
    {
      "url": "https://www.apify.com/"
    }
  ],
  "mode": "changesOnly",
  "maxPages": 5
}
```
