## 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

## Chrome Web Store Scraper: Extension Data, Users & Permissions

Scrape **public Chrome Web Store extension data** in bulk: paste extension IDs or store URLs, or a **category page**, and get one clean row per extension with **name, users, rating, rating count, version, last updated, created date, category, size, languages, manifest version, permissions, host permissions**, website, support and privacy links, and the **publisher's company name**. **Plain HTTP, no browser, no login.** **No reviews, no reviewer data, no developer email, phone or address.** **$1.50 per 1,000 extensions. Not-found, failed and invalid items are free.**

### What does this Chrome Web Store scraper do?

- Reads the public detail page of each extension (`chromewebstore.google.com/detail/<id>`)
- Accepts **32-letter extension IDs**, new store URLs and old `chrome.google.com/webstore` URLs
- Reads **category and collection pages** (for example `/category/extensions/productivity/workflow`) and scrapes the extensions listed there
- Optionally follows the **related extensions** on each page to map a niche from one seed
- Parses the **published manifest**: manifest version (MV2 or MV3), permissions, optional permissions, host permissions and content-script match patterns
- Respects **robots.txt** (never touches /reviews, /search, /support or /privacy pages) and paces itself at about 2 requests per second

### Who is it for?

- **Extension developers and indie makers:** track competitors' users, ratings and release cadence, and find gaps in a category
- **Security and IT teams:** audit what permissions and site access a list of extensions asks for, and spot MV2 extensions
- **Market researchers and investors:** size a niche by users and ratings, and see which publishers are companies
- **AI agents and automations:** stable JSON through the Apify API or MCP, with a predictable price per extension

### Quick start

1. Paste extension IDs or store URLs (the form is prefilled with Bitwarden and Google Translate), or a category page URL.
2. Set **Max extensions** (20 for a quick test).
3. Click **Start**, then download JSON, CSV or Excel, or read it through the API.

#### Sample output

From a real run on **November 12, 2026**:

| Extension | Users | Rating | Ratings | Category | Version | Publisher |
|---|---|---|---|---|---|---|
| Adobe Acrobat: PDF edit, convert, sign tools | 352,000,000 | 4.38 | 64,678 | workflow | 26.10.2.2 | Adobe, Inc. |
| Google Translate | 39,000,000 | 3.0 | 44,865 | education | 2.0.18 | Google Ireland, Ltd. |
| Adblock Plus - free ad blocker | 40,000,000 | 3.89 | 188,172 | workflow | 4.51.0 | eyeo GmbH |
| Tampermonkey | 12,000,000 | 4.81 | 73,119 | workflow | | empty (not a declared trader) |
| Bitwarden Password Manager | 7,000,000 | 2.86 | 8,140 | privacy | 2026.10.2 | Bitwarden Inc. |

If an ID has no public listing (removed, unlisted or mistyped), the row has `status: "not-found"`. Invalid inputs and fetch failures get `status: "error"` with an `errorCode` and a plain-English `errorMessage`. None of these are charged.

#### Example inputs

A list of extensions by ID or URL:

```json
{ "extensions": ["nngceckbapebfimnlniiiahkandclblb", "https://chromewebstore.google.com/detail/google-translate/aapbdbdomjkkjkaonfhkkikfgjllcleb"] }
```

Everything listed on a category page:

```json
{ "categoryUrls": ["https://chromewebstore.google.com/category/extensions/productivity/workflow"], "maxItems": 50 }
```

Map a niche from one seed extension (related extensions):

```json
{ "extensions": ["nngceckbapebfimnlniiiahkandclblb"], "includeRelated": true, "maxItems": 40, "includeDescription": false }
```

### Output fields

| Field | What it means |
|---|---|
| `extensionId`, `name`, `url` | ID, listed name, public store link |
| `shortDescription`, `description` | Summary line and long description (cut at `maxDescriptionChars`) |
| `users`, `rating`, `ratingCount` | User count as shown by Google (rounded), average stars, number of ratings |
| `category`, `categoryPath` | Store category |
| `version`, `lastUpdated`, `createdAt`, `size` | Current version, last update, first created, package size |
| `languages`, `languageCount` | Supported languages |
| `manifestVersion`, `permissions`, `optionalPermissions`, `hostPermissions`, `contentScriptMatches` | From the published manifest |
| `websiteUrl`, `supportUrl`, `privacyPolicyUrl`, `iconUrl` | Links from the listing |
| `publisherName`, `publisherIsTrader` | Company name, shown only when the publisher declared itself a trader (a business) |
| `relatedExtensionIds` | IDs shown as related on the page |
| `status`, `errorCode`, `errorMessage` | ok, not-found or error, and why |

### How much does it cost?

**$1.50 per 1,000 extensions** ($0.0015 each). No start fee. Not-found, failed and invalid items are free. `maxItems` and the run's max-charge setting cap spend: 20 extensions cost $0.03.

### Privacy and data we leave out

Listings also carry developer contact details (email, phone, street address) and, for some publishers, personal names. **This Actor never reads or outputs them.** For publishers who did not declare themselves a business, `publisherName` is left empty. No reviews or reviewer names are collected.

### Is it legal?

The Actor only reads public pages that the Chrome Web Store's robots.txt allows, without logging in, at a gentle pace. Google's Terms of Service prohibit automated access that violates machine-readable instructions such as robots.txt, and this Actor follows them. You are responsible for how you use the data; check the terms that apply to you.

# Actor input Schema

## `extensions` (type: `array`):

One per line: a 32-letter extension ID (e.g. nngceckbapebfimnlniiiahkandclblb) or a detail URL from chromewebstore.google.com or the old chrome.google.com/webstore. Category URLs pasted here are treated as category pages.

## `categoryUrls` (type: `array`):

Optional. Public listing pages such as https://chromewebstore.google.com/category/extensions/productivity/workflow. The extensions shown on the page (usually about 30) are scraped. Search pages are not used (robots.txt disallows them).

## `includeRelated` (type: `boolean`):

Add the 'related' extensions shown on each detail page to the queue (up to Max items). Good for mapping a niche from one seed extension.

## `includeDescription` (type: `boolean`):

Include the long store description text (cut at Max description length).

## `maxDescriptionChars` (type: `integer`):

Characters of the long description kept per extension.

## `maxItems` (type: `integer`):

Exact maximum number of extensions scraped and charged in this run. Not-found and failed items do not count. The run's max-charge setting is also respected.

## `language` (type: `string`):

Language code for store text (hl parameter), e.g. en, de, fr, pt-BR. Category names and descriptions follow it when the developer provided a translation.

## `maxConcurrency` (type: `integer`):

Pages in flight (1-5). Requests are also paced at about 2 per second overall.

## `requestTimeoutSecs` (type: `integer`):

Seconds to wait for one page. Timeouts, 429 and 5xx get up to 3 attempts with backoff.

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,hillcountrybots/chrome-web-store-scraper"
        }
    }
}
```

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).
