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.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.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/platform/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 ## PWA Audit Check if any URL meets Progressive Web App installability criteria — manifest validity, service worker registration, HTTPS, icon sizes, and required manifest fields. Returns a 13-point checklist + A-F grade + binary `isInstallable` flag. ### What it does Loads the URL in real Chromium, fetches and parses the linked Web App Manifest, validates required fields against [Chrome's installability requirements](https://web.dev/articles/install-criteria), checks for a registered service worker, and grades the result. ### Checklist | Check | Severity | Weight | |---|---|---| | HTTPS or localhost | critical | 15 | | Web App Manifest linked | critical | 15 | | Manifest parses as valid JSON | critical | 10 | | Has `name` | critical | 5 | | Has `short_name` | important | 3 | | Has `start_url` | critical | 5 | | `display` is standalone / fullscreen / minimal-ui | critical | 8 | | Has 192×192+ icon | critical | 8 | | Has 512×512+ icon | critical | 8 | | Has maskable icon | important | 5 | | Has `theme_color` | important | 4 | | Has `background_color` | important | 4 | | Service worker registered | critical | 10 | ### Input ```json { "url": "https://web.dev" } ```` ### Output ```json { "url": "https://web.dev", "grade": "A", "percentage": 92, "isInstallable": true, "manifest": { "name": "web.dev", "short_name": "web.dev", "..." : "..." }, "serviceWorker": { "supported": true, "registrationCount": 1, "scopes": ["..."], "active": true }, "checklist": [ { "check": "HTTPS or localhost", "passed": true, "severity": "critical", "weight": 15 }, ... ] } ``` ### Use cases - **PWA migration sprints** — audit your full site to find pages missing the manifest - **Lighthouse alternative for CI** — faster than Lighthouse for the PWA-only checks - **Competitive analysis** — see which competitors have a real PWA vs a fake banner ### Pricing model (when published) Pay-per-result: **$0.05 per URL audited.** Audits take ~5-10 seconds. ### Author note Built by [Peak Post](https://peakpost.ca), the developer behind 22 published Chrome extensions. ### Roadmap - v1.1: shortcut + screenshots manifest field validation - v1.2: offline page check (load URL, force offline, verify SW responds) - v1.3: WebShare + WebPush API detection # Actor input Schema ## `url` (type: `string`): A single page URL to audit. ## `urls` (type: `array`): Array of URLs (max 1000). ## Actor input object example ```json { "url": "https://web.dev" } ``` # API You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup. ## JavaScript example ```javascript import { ApifyClient } from 'apify-client'; // Initialize the ApifyClient with your Apify API token // Replace the '' with your token const client = new ApifyClient({ token: '', }); // Prepare Actor input const input = {}; // Run the Actor and wait for it to finish const run = await client.actor("pattonholdings/pwa-audit").call(input); // Fetch and print Actor results from the run's dataset (if any) console.log('Results from dataset'); console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`); const { items } = await client.dataset(run.defaultDatasetId).listItems(); items.forEach((item) => { console.dir(item); }); // 📚 Want to learn more 📖?
