The Actor is free to use, and you only pay for the Apify platform usage, which gets cheaper the higher subscription plan you have.

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. 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. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js/docs.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python/docs.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## Web App Manifest Auditor Audit one public web page for web app manifest and favicon readiness. The actor fetches the page, finds manifest and icon links, validates the manifest JSON, and returns a structured score with issues and recommendations. ### Use cases - Check launch pages for missing favicons or web app manifests. - Monitor PWA installability basics across marketing sites and docs portals. - Validate CMS templates after redesigns or migrations. - Feed structured manifest and icon diagnostics into QA dashboards. ### Input | Field | Type | Required | Description | | --- | --- | --- | --- | | `startUrl` | string | Yes | Public HTTP or HTTPS page URL to audit. Credentials and private network targets are rejected. | | `timeoutSeconds` | integer | No | Request timeout for page and manifest fetches. Default is 10 seconds. | ### Output Each run pushes one dataset item. | Field | Type | Description | | --- | --- | --- | | `inputUrl` | string | Original URL submitted in the input. | | `normalizedInputUrl` | string | URL after adding a default HTTPS scheme when omitted. | | `finalUrl` | string | Final page URL after safe redirects. | | `status` | integer or null | HTTP status returned by the page fetch. | | `ok` | boolean | True when the page fetch completed with a 2xx or 3xx status and no fetch error. | | `checkedAt` | string | ISO timestamp for the audit. | | `manifestUrl` | string or null | First resolved `rel="manifest"` URL found on the page. | | `manifestStatus` | integer or null | HTTP status returned by the manifest fetch. | | `manifestValid` | boolean | True when the manifest was reachable and parsed as JSON. | | `manifestName` | string or null | Manifest `name`, when present. | | `manifestShortName` | string or null | Manifest `short_name`, when present. | | `faviconCount` | integer | Number of favicon, shortcut icon, mask icon, and Apple touch icon links found. | | `favicons` | array | Icon link records with `rel`, `href`, `resolvedHref`, `sizes`, and `type`. | | `manifestIconCount` | integer | Number of icons declared in the manifest. | | `manifestIcons` | array | Raw manifest icon records. | | `hasName` | boolean | True when the manifest has `name` or `short_name`. | | `hasStartUrl` | boolean | True when the manifest has `start_url`. | | `hasDisplay` | boolean | True when the manifest has `display`. | | `hasThemeColor` | boolean | True when the manifest has `theme_color`. | | `score` | integer | Readiness score from 0 to 100. | | `grade` | string | Letter grade from A to F. | | `issues` | array | Problems found during the audit. | | `recommendations` | array | Suggested fixes. | | `error` | string or null | Fetch or validation error, when one occurred. | ### Example input ```json { "startUrl": "https://example.com", "timeoutSeconds": 10 } ```` ### Example output ```json { "inputUrl": "https://example.com", "normalizedInputUrl": "https://example.com/", "finalUrl": "https://example.com/", "status": 200, "ok": true, "checkedAt": "2026-07-15T00:00:00.000Z", "manifestUrl": "https://example.com/site.webmanifest", "manifestStatus": 200, "manifestValid": true, "manifestName": "Example App", "manifestShortName": "Example", "faviconCount": 1, "favicons": [ { "rel": "icon", "href": "/favicon.ico", "resolvedHref": "https://example.com/favicon.ico", "sizes": "any", "type": null } ], "manifestIconCount": 2, "manifestIcons": [ { "src": "/icon-192.png", "sizes": "192x192", "type": "image/png" }, { "src": "/icon-512.png", "sizes": "512x512", "type": "image/png" } ], "hasName": true, "hasStartUrl": true, "hasDisplay": true, "hasThemeColor": true, "score": 100, "grade": "A", "issues": [], "recommendations": [], "error": null } ``` ### Security The actor fetches only public HTTP and HTTPS URLs. It rejects URL credentials, localhost and private IP literals, and hostnames that resolve to private IPv4 or IPv6 ranges. Redirect targets are validated before following. Response bodies are capped at 2 MB. ### Pricing Suggested pay-per-event pricing: | Event | Suggested price | | --- | ---: | | Actor start | $0.005 | | Page audited | $0.01 | This keeps single-page checks inexpensive while supporting scheduled QA and batch workflows. ### FAQ #### Does this check full PWA installability? No. It checks manifest and icon readiness signals that can be verified from static HTML and manifest JSON. It does not run a browser, service worker, or Lighthouse audit. #### Does it download every icon? No. It extracts icon declarations and manifest icon records. It does not fetch each image file, which keeps runs fast and low maintenance. #### Can I audit private staging sites? No. The actor is designed for public unauthenticated pages only and blocks private network targets for SSRF safety. # Actor input Schema ## `startUrl` (type: `string`): Public HTTP or HTTPS page URL to audit.
