Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Clear out junk files and repair common Windows errors3Scan for outdated or missing drivers - takes under a minuteChoose a hosted screenshot API when you can provide a valid session cookie or authorization header; choose browser automation when the capture must complete a login form or other browser steps. For a hosted option, ScreenshotNeo is the first alternative to try: it removes cookie banners, popups and chat widgets before capture, bills only clean shots, and offers an API starting with 1,000 free monthly screenshots. Its documented feature list does not establish that it can perform an interactive login or inject authentication cookies, so use it for a protected page only if you can provide the needed access through a supported method and verify the result. For documented cookie, Basic Auth and Authorization-header capture, Cloudflare Browser Run is a strong candidate; ScreenshotOne also documents cookies and custom headers. For form-driven login, Playwright gives you control over the browser flow.
What “behind a login” means for screenshot capture
A screenshot service can reach an authenticated page in different ways. The key question is not simply whether the site has a login, but how the browser proves it is signed in and who is responsible for obtaining that proof.
- Session cookie: A browser sends a cookie issued after login. The capture service must receive a valid cookie, and you must obtain and refresh it.
- Authorization header or token: A request includes a bearer token or another custom authorization header. This works only if the site accepts that credential for the page and its required requests.
- HTTP Basic Authentication: The browser authenticates using a username and password challenge. This is distinct from an HTML login form.
- Interactive login: The browser must load a form, enter credentials, submit it, follow redirects, and perhaps complete additional steps. This requires browser interaction, not merely attaching a cookie or header.
These methods are not interchangeable. A hosted API accepting a cookie does not necessarily log in to the site, obtain the cookie, or refresh an expired session.

Compare the documented options
| Option | Documented authentication | Best fit | Boundary to keep in mind |
|---|---|---|---|
| ScreenshotNeo | The supplied product information lists custom headers and cookies among its capture options; the documented facts here do not establish a form-login workflow. | Try first when you can supply access through a supported cookie or header and want clean screenshots, with banners and widgets removed before capture. | Do not assume it performs an interactive login or can bypass access controls. Confirm your authentication approach and inspect the captured page. |
| Cloudflare Browser Run | Session cookies, HTTP Basic Authentication, and a custom Authorization header. | A hosted screenshot request where you already have a valid cookie or credential. | The documented screenshot endpoint covers credential injection; it does not establish arbitrary multi-step login interaction in a one-shot request. Cloudflare Browser Run documentation |
| ScreenshotOne | Custom authentication headers and session cookies. | Hosted capture when you can supply valid cookie or header data. | Its guide notes that you may need separate code to obtain the site’s cookies; it does not mean the API logs in for you. ScreenshotOne authentication guide |
| Capture API | HTTP Basic Authentication and custom user-agent configuration. | A page protected by Basic Auth or one where the user-agent needs configuration. | The reviewed authentication page does not substantiate general session-cookie injection or form-based login. Capture documentation |
| Playwright | Browser-driven login, reusable browser storage state, and screenshots. | A flow involving form submission, redirects, or custom browser actions. | You operate the automation and secure its saved authentication state. Session storage requires separate handling in the documented workflow. Playwright authentication documentation · Playwright screenshots documentation |
This is a capability comparison, not a performance ranking: the available documentation does not establish which option is fastest, most reliable, or most successful across arbitrary protected sites.
Choose by authentication method
You already have a valid cookie or token
Start with a hosted service that documents the credential format your site accepts. Cloudflare Browser Run documents cookies and Authorization headers; ScreenshotOne documents cookies and custom headers. ScreenshotNeo is the first alternative to try if its supported cookie or header options fit your setup and you want its clean-shot behavior. The application or script that captures the page remains responsible for safely acquiring and refreshing credentials.

The site uses HTTP Basic Authentication
Cloudflare Browser Run and Capture both document Basic Auth. Confirm that the target actually uses the browser’s Basic Auth challenge rather than a page with a username-and-password form. A form login is a different workflow.
The browser must complete a login flow
Use Playwright when login requires visiting a page, filling fields, clicking, waiting for redirects, or performing other browser actions. The documented Playwright workflow can save browser storage state for later reuse. If considering a hosted service instead, verify that it supports the exact interaction sequence you need; cookie or header support alone is not proof of that capability.

You are unsure which method the site uses
- Sign in normally in a browser and inspect the site’s authentication design with your development tools or site administrator.
- Determine whether a valid session cookie or accepted header can be reused, whether the site uses Basic Auth, or whether a browser must submit a form.
- Use an authorized test account and test page before automating a production account.
- Compare the final URL and a page-specific element with the expected signed-in page. An image response by itself does not prove the capture is authenticated.
Use Playwright when capture must log in
This Node.js example uses Playwright’s documented storage-state approach: sign in once, save the resulting browser state, then load that state for later screenshots. Replace the example URL, selectors, and any site-specific readiness check. Install Playwright and its browser before running the script; the login selectors must match the target site’s form.
const { chromium } = require('playwright');
(async () => {
const browser = await chromium.launch({ headless: true });
const context = await browser.newContext();
const page = await context.newPage();
await page.goto('https://example.com/login');
await page.locator('input[name="username"]').fill(process.env.SITE_USER);
await page.locator('input[name="password"]').fill(process.env.SITE_PASSWORD);
await page.locator('button[type="submit"]').click();
// Replace this with a reliable signed-in-page check for your site.
await page.waitForURL('**/dashboard');
await page.screenshot({ path: 'authenticated-page.png', fullPage: true });
await context.storageState({ path: 'playwright/.auth/state.json' });
await browser.close();
})();For later captures, create a context with the saved state, then navigate and take the screenshot:

Protect credentials and validate the result
Keep authentication state private
Playwright warns that saved browser state can contain sensitive cookies and headers capable of impersonating an account. Do not commit a state file to a repository. Store credentials outside source code, use a least-privilege test account where possible, and revoke or rotate an exposed session. Before sending sensitive page content to a hosted provider, review its handling and retention terms.
Check that the screenshot is truly authenticated
- Verify the final URL is the expected protected page, not a login route or redirect.
- Check for a visible, page-specific signed-in element or account identifier.
- Look for login prompts, access-denied messages, or an empty shell that can appear when authentication is missing or expired.
- Repeat the capture after the session is refreshed if the page unexpectedly shows a signed-out state.
Troubleshooting common failures
The screenshot shows the login page
The cookie or token may be missing, expired, scoped to another domain, or not accepted by the page’s required requests. Confirm the credential using an authorized browser session, then pass the correct current value or use Playwright to establish state through login.

The API returns an image, but the page is blank or incomplete
A successful image response only confirms that an image was produced. The page may still be loading, require a readiness condition, or depend on authentication for data requests. Wait for a page-specific element and inspect the resulting image before treating it as a successful authenticated capture.
A cookie works in your browser but not in the capture
Check whether it is still valid and whether its domain, path, security, and same-site conditions match the target navigation. Sites may also need more than one cookie or a related authorization header. Obtain fresh state through an authorized login rather than copying stale credentials.
The login automation stops at a redirect or challenge
Make the Playwright flow wait for the actual signed-in URL or a unique page element, and handle expected redirects deliberately. The cited documentation does not establish that any hosted option or automation flow can handle every MFA or CAPTCHA challenge; do not assume a challenge can be bypassed.
Saved Playwright state does not preserve the session
The site may rely on session storage, which the documented storage-state workflow does not automatically persist. Implement separate session-storage handling appropriate to the application, or repeat the login flow when creating the capture context.
Cost and operational trade-offs
Hosted capture reduces the browser infrastructure you need to operate, but you still have to supply and protect valid credentials and confirm the resulting page. Playwright gives you control over login interaction and browser steps, at the cost of maintaining automation, browser dependencies, and secure session storage. The cited product documentation does not provide a common basis for comparing latency, uptime, or success rates, so choose using the authentication workflow and your own authorized validation rather than an assumed provider ranking.
