## Pricing

from $1.28 / 1,000 websites

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?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
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.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## 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.

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 examples already wired to this Actor's own input schema, see the [API](#api) section below.

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`).

# README

## Website Technology Stack Detector (CMS, analytics, chat, payments, hosting)

Find out what any website is built with: CMS and e-commerce platform (WordPress, Shopify, Webflow, Wix...), JS framework, analytics and ad pixels, chat widget, payment providers, email marketing tool, CDN/hosting, server and the company's email provider (Google Workspace, Microsoft 365...). 200+ signatures, read from the public homepage, headers and DNS. Bulk: thousands of domains per run. For sales prospecting, competitor research and lead qualification.

### What you can use it for

- Sales prospecting: every Shopify store using Klaviyo but no chat widget; WordPress sites without a CDN
- Competitor and market research: which platforms, analytics and payment providers a list of companies uses
- Lead qualification: enrich a CRM list with CMS, e-commerce platform, email provider and hosting
- Agencies: audit a client list for outdated or missing tooling

### Why this one

- 200+ signatures across CMS, e-commerce, frameworks, analytics/pixels, chat, payments, email marketing, widgets, CDN/hosting, server and the company's email provider (from DNS MX)
- Reads only the public homepage, its headers and DNS: fast, polite, honors robots.txt
- Each category is its own column, plus a combined technologies list and the external script hosts for your own rules
- Pay only for results: **$1.50 per 1,000 websites**. No subscription.

### Input

- **Websites** (`websites`): Domains or URLs, one per line.
- **Max sites** (`maxResults`) Default: `10000`.

### Output

One row per website in the dataset (JSON, CSV, Excel, or through the API). Sample:

### Tips

- Detection is from the homepage HTML as served; single-page apps that render everything in JavaScript may show fewer technologies.
- emailProvider comes from MX records: Google Workspace, Microsoft 365, Zoho, Proofpoint, Mimecast and others; 'Self-hosted/other' when none matched.

### Integrations and API

Run it on a schedule, trigger it from the API or a webhook, and send results to Google Sheets, Zapier, Make, Slack, a database or your own code with the platform's standard integrations.

### Data and fair use

This tool reads only public sources (official APIs, public feeds or pages the publisher makes available to everyone) and respects robots.txt and rate limits. You are responsible for using the data in line with the source's terms and applicable law.

### How much it costs

You pay per result (pay-per-event), nothing per month and nothing when a run returns nothing. The price is **$1.50 per 1,000 websites** on the Free plan, with automatic discounts on paid plans (Bronze −5%, Silver −10%, Gold −15%, Platinum −20%).

Worked examples:

- 100 websites → **$0.15**
- 1,000 websites → **$1.50**
- 10,000 websites → **$15.00**

Platform usage (compute, storage) is included in the price: the actor runs at a small memory setting by default, so a typical run of 1,000 websites finishes in well under a minute.

### FAQ

**A site came back as reachable: false. Why?**

The site blocked the request or did not answer within the timeout. The actor retries blocked sites once through Apify proxy; a few sites still refuse automated visits. Those rows are still charged because the check ran; most lists see under 5% of these.

**Why are some fields empty?**

A field is `null` when the source does not publish it for that row. The output keeps every column so your spreadsheet or integration always sees the same shape.

**Can I run it on a schedule?**

Yes. Use Apify Schedules (daily, hourly, cron) and connect the run to Make, Zapier, n8n, Google Sheets, a webhook or the API. Each run writes a dataset you can download as JSON, CSV or Excel.

**Is there a free trial?**

The Apify Free plan includes $5 of monthly platform credit, enough to try this actor on a few hundred results at no cost. There is no subscription for the actor itself.

**Can an AI agent use this?**

Yes. The actor is available through Apify's MCP server and the API, so LLM agents (Claude, ChatGPT, LangChain, CrewAI) can call it as a tool with the same input.

**What happens if something fails?**

Runs log every skipped item with a reason. If the source is down, the actor stops cleanly and you are only charged for the results it returned.

### Changelog

- **2026-10-18** — Lower price with Bronze/Silver/Gold discounts; smaller default memory (cheaper runs); clean table view of results; FAQ and cost examples; blocked sites are retried once through Apify proxy.

## CLI example

```bash
echo '{
  "websites": [
    "apify.com",
    "shopify.com",
    "nytimes.com",
    "gymshark.com"
  ]
}' |
apify call larkmoor/website-tech-stack --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,larkmoor/website-tech-stack"
        }
    }
}
```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
