Connect Playwright to BrowserCat, set a mobile-sized viewport before opening the site, then save a screenshot with page.screenshot(). A narrow viewport tests responsive layout; it does not, by itself, make the browser appear to be in India or emulate every property of a real phone.
How do I take a mobile screenshot of an Indian website?
BrowserCat supplies the hosted Chromium browser; Playwright controls it. You need a BrowserCat API key and the playwright-core package. Store the key in an environment variable rather than placing it in source code. BrowserCat’s documented connection uses a WebSocket endpoint and an Api-Key header. See the BrowserCat Quick Start for its current setup details.

Choose viewport dimensions for the responsive layout you want to inspect. The example uses 390 × 844 pixels as an illustrative mobile-sized viewport, not a BrowserCat-prescribed India setting or an exact model of a particular phone.
-
Connect, create a context with that viewport, navigate to the site, and save the screenshot.
This complete JavaScript example saves the initially visible viewport to mobile.png:
import * as pw from 'playwright-core';
const browser = await pw.chromium.connect(
'wss://api.browsercat.com/connect',
{ headers: { 'Api-Key': process.env.BROWSERCAT_API_KEY } }
);
try {
const context = await browser.newContext({
viewport: { width: 390, height: 844 }
});
const page = await context.newPage();
await page.goto('https://example.in', { waitUntil: 'load' });
await page.screenshot({ path: 'mobile.png', fullPage: false });
} finally {
await browser.close();
}Replace https://example.in with the page you want to capture. The dimensions and URL here are examples; choose a width and height that match your test. The try/finally ensures the remote browser is closed even if navigation or capture fails.

How do I set a mobile viewport in BrowserCat?
Set viewport when creating the Playwright browser context, before opening the page. The website then receives a browser window with those dimensions from the start, allowing it to select its responsive layout. Playwright’s Page API documents screenshots and page behavior; its emulation documentation explains the additional properties available through device emulation.
For a breakpoint check, viewport width and height are usually the key settings. For a closer approximation of a named device, use a Playwright device descriptor or explicitly configure relevant properties such as user agent, screen size, and touch support. Device emulation can cover those properties; changing viewport dimensions alone does not set them all. Playwright also supports locale and timezone emulation, which can matter when a site changes formatting or content based on those settings.
Viewport screenshot or full-page screenshot?
By default, page.screenshot() captures the visible viewport. Set fullPage: true to capture the entire scrollable page instead:
await page.screenshot({ path: 'full-page.png', fullPage: true });Use the viewport capture when checking what appears on the first screen at the chosen width. Use a full-page capture when you need the page from top to bottom. A full-page image is not a sequence of separate mobile screens; it is one capture of the page’s scrollable content.

Wait for the content you need before capturing
The example waits for the page’s load event, but modern sites may render important content later. If the content you need appears after an application update, wait for a specific selector or other page-ready condition before calling screenshot(). For example:
await page.goto('https://example.in', { waitUntil: 'load' });
await page.locator('main article').waitFor({ state: 'visible' });
await page.screenshot({ path: 'article.png' });Replace main article with a selector that identifies content on the target page. Waiting for a meaningful element is more reliable than assuming that a load event means every dynamic component has finished rendering.
Does a mobile-width screenshot mean the browser is in India?
No. The site’s Indian domain or content does not determine the cloud browser’s public IP location. BrowserCat says sessions are placed automatically near the request and that explicit region pinning is not currently available. If the site varies its response by IP, blocks traffic from outside India, or shows a location-specific version, a narrow viewport alone will not reproduce that behavior. BrowserCat documents a third-party proxy as the route to precise geographic control; see its Browser Region, Browser Configuration, and Third-Party Proxy documentation for current configuration requirements.

Browser availability and compatibility
As of the documentation reviewed on October 3, 2026, BrowserCat lists Chromium and Chrome as supported, while Firefox and WebKit are described as forthcoming. This workflow therefore uses Playwright’s Chromium client. Browser support can change, so check BrowserCat’s Browser Type documentation before relying on another engine.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Common problems and fixes
-
The page still looks like desktop. Confirm that the context’s
viewportis set before navigation and that the page is not overriding its layout. Check the actual width being tested and the site’s responsive breakpoint. -
The screenshot misses dynamic content. Add a wait for a relevant selector or application-ready condition after navigation. A successful load event does not establish that every asynchronously rendered component is ready.
Recommended Free Tools
Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy. -
The site shows the wrong regional content or blocks the request. A mobile viewport does not set the browser’s IP geography. BrowserCat does not currently document region pinning; use an appropriately configured third-party proxy if precise geographic routing is necessary.

ScreenshotNeo offers a screenshot API: one GET request with a URL returns an image or PDF. Its clean-shot workflow accepts consent banners like a visitor and removes more than 60 known consent platforms, newsletter popups, and chat widgets before capture; each of those steps can be turned off. Bot checks or CAPTCHAs, blank pages, timeouts, failed loads, and cache hits cost nothing, and responses identify the page verdict and billing status in headers. Its MCP server provides take_screenshot, get_page_info, and capture_pdf tools for Claude, Cursor, and other MCP clients.
For a URL-only capture, the cURL call is:
curl -G "https://api.screenshotneo.com/v1/shot" -d access_key=YOUR_API_KEY --data-urlencode url=https://example.in -o shot.webpSee the ScreenshotNeo API documentation for request options, including viewport settings. This one-call example is not a substitute for BrowserCat when you specifically need Playwright-controlled browser emulation or India-specific proxy routing.
ScreenshotNeo includes 1,000 shots per month on its free plan with no card; paid plans start at $5 for 3,000 shots. Sign up for free ScreenshotNeo access.
Frequently Asked Questions
Does the 390 × 844 example represent a specific phone?
No. It is an illustrative viewport size; use the dimensions appropriate to your own responsive test.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Can a mobile-width capture prove that an Indian visitor sees the same page?
No. The viewport sets dimensions, not IP location. Location-sensitive results require separate geographic routing.
