You wire up Playwright, point it at a protected site, and get a CAPTCHA wall or an empty page. Running a real browser is the easy part. Keeping it unblocked, fingerprinted right, and stable across thousands of pages is where the work lives.

That gap is what a cloud browser API closes. This guide ranks the best options for web scraping in 2026, from managed stealth browsers to self-hosted open-source engines. Each entry covers the job it does best and its limits.

[Cloud Browser: What Is It and How to Use ItLearn what cloud browsers are, how they work, and how to use them for web scraping, automation, and AI agents. Covers practical code examples with Playwright and Puppeteer.](https://scrapfly.io/blog/posts/what-is-a-cloud-browser)



## Key Takeaways

The best cloud browser API depends on one thing: how much of the unblocking you want to own yourself, versus pay someone to handle.

- **Cloud is not a synonym for headless**: headless is the interface mode, cloud is the hosting model
- **Use a cloud browser for full interaction**: logins, clicks, multi-step flows
- **Use a rendering scraper API for HTML only**: it costs less than a live browser
- **Self-hosting's hard part isn't the browser**: fingerprinting, proxies, anti-bot, scaling
- **Agentic browsing needs a stealth browser underneath**: off-the-shelf or DIY
- **Scrapfly Cloud Browser API leads here**: stealth Chromium over CDP, pay-per-active-time

## Which Cloud Browser API Is Best for Web Scraping?

These are the best cloud and headless browser APIs for web scraping in 2026, ranked by the job each does best. The top three are managed Scrapfly surfaces, followed by the strongest open-source engines you can self-host.

- **Best overall managed cloud browser**: Scrapfly Cloud Browser API
- **Best for rendered HTML at scale**: Scrapfly Web Scraping API
- **Best for natural-language browsing**: Scrapfly AI Browser Agent
- **Best open-source engine to self-host**: Playwright
- **Best for Node and Chrome self-hosting**: Puppeteer
- **Best self-hosted multi-language grid**: Selenium Grid
- **Best open-source agentic framework**: Browser Use

The table below compares all seven on the factors that decide a scraping job. That means who manages the browser, whether anti-bot is built in, and how you pay.

| Tool | Type | Best for | Anti-bot and stealth built in? | Language / SDK support | Pricing model |
|---|---|---|---|---|---|
| **Scrapfly Cloud Browser API** | Managed | Real-browser interaction at scale | Yes (Scrapium + ASP) | Playwright and Puppeteer over CDP, Selenium via a Playwright bridge; Python/JS/Go/Rust SDKs | Credits (active browser time) |
| **Scrapfly Web Scraping API** | Managed | Rendered HTML at scale | Yes (ASP) | Python, TypeScript, Go, Rust, Scrapy | Credits (per successful request) |
| **Scrapfly AI Browser Agent** | Managed (agentic) | Natural-language browsing | Yes (runs on Cloud Browser) | Plain-language goals / API | Credits (active browser time) |
| **Playwright** | Self-hosted OSS | Cross-browser self-hosting | No (you build it) | Python, JS, Java, .NET | Free (you pay infra) |
| **Puppeteer** | Self-hosted OSS | Node + Chrome scraping | No (you build it) | Node (JS/TS) | Free (you pay infra) |
| **Selenium Grid** | Self-hosted OSS | Multi-language browser grids | No (you build it) | Python, Java, JS, C#, Ruby, more | Free (you pay infra) |
| **Browser Use** | Agentic OSS | DIY LLM browser agents | No (depends on backend) | Python | Free (you pay infra + LLM) |



## What Is a Cloud Browser API?

A cloud browser API is a service that runs a real browser on remote servers. It exposes that browser over the Chrome DevTools Protocol (CDP) or a WebSocket.

You point your existing browser automation code at it instead of launching a browser on your own machine. Which clients attach natively depends on the provider and the protocol it exposes.

A headless browser is a browser running without a visible interface. A cloud browser is a browser running on remote infrastructure and exposed through a network endpoint. Most cloud browser APIs run headless Chromium, which is why the terms overlap in scraping searches, but they describe different parts of the setup. Our [headless browser vs cloud browser](https://scrapfly.io/blog/posts/headless-browser-vs-cloud-browser) comparison covers the split in full.

A cloud browser beats a local one for scraping in three ways:

- **No fleet to run**: no Docker images, browser version updates, or dependency drift to maintain.
- **Instant scale**: open many concurrent sessions without provisioning servers.
- **Built-in evasion**: the good providers manage fingerprints, TLS profiles, and proxies for you.

For a handful of scrapes a day, a local browser is fine. For production volume on protected sites, a cloud browser removes the parts that break at scale.



## How Did We Rank These?

We ranked each tool on the factors that decide a real scraping job. Those are framework support, built-in anti-bot and proxies, how you connect, and how you pay.

Where possible, we connected with Playwright in Python and ran the same task against `https://web-scraping.dev/products`.

This list is not neutral about who we are. Scrapfly's own surfaces rank first because we built them for exactly this job, and we explain the honest limits of each.

The other entries are open-source projects you can run yourself, included because they are the strongest self-hosted bases.

### How Should You Test a Cloud Browser API for Protected, Stateful Workflows?

Run a short trial that mirrors your real job instead of a single page load. Four checks separate a browser that demos well from one that survives production.

**Protected flow completion.** Navigate to your actual target, trigger a protected in-page request, then do the next interaction. A first page load that succeeds proves very little, because the block usually lands on the second request or after a click.

**Transport compatibility.** Run your existing Playwright or Puppeteer path and record any protocol or schema errors. Confirm the provider documents your client before assuming it attaches. Selenium WebDriver in particular does not natively attach to a remote CDP WebSocket, so look for a documented bridge.

**State continuity.** Log in, disconnect, reconnect, then verify cookies, localStorage, sessionStorage, and the exit IP you expected. Scrapfly documents this path in [Session Resume](https://scrapfly.io/docs/cloud-browser-api/session-resume), which needs both a `session` identifier and `auto_close=false` to keep the browser alive between connections.

**Failure visibility.** Ask what the trial shows you when a run fails: session recordings, console and network evidence, error categories, retry boundaries, and metrics. Scrapfly's [Debug Mode](https://scrapfly.io/docs/cloud-browser-api/debug-mode) records a session as video for replay when you connect with `debug=true`, and the [Monitoring API](https://scrapfly.io/docs/cloud-browser-api/monitoring) reports total runs, runtime, bandwidth, and success rate over windows up to 90 days, on Enterprise or Custom plans only.

Score every provider you trial on all four, not on whether the first page loaded.

We do not rank managed competitors here. Comparing our own product against rivals we sell against would not give you an honest read.



## 1. Scrapfly Cloud Browser API: Best Overall Managed Cloud Browser

**Best for:** real-browser interaction at scale without running browser infrastructure yourself.

The [Scrapfly Cloud Browser API](https://scrapfly.io/products/cloud-browser-api) is a managed stealth browser built for scraping. It runs a Chromium fork over a CDP WebSocket. You connect your existing Playwright or Puppeteer code over CDP, and Scrapfly handles anti-bot and fingerprinting.

The stealth comes from Scrapium, a custom Chromium fork with 500+ patched source files and 30,000+ spoofed signals from real device profiles.

Session Resume persists cookies and storage across reconnects, and Anti-Scraping Protection (ASP) clears Cloudflare, DataDome, and similar systems on the same connection.

Billing is the part developers tend to like: you pay only for active browser time, and crashed sessions are free.

The honest limit is cost per page. A real browser is pricier than a static fetch, so if you do not need interaction, the Web Scraping API below is cheaper.

#### Code Example

python```python
from playwright.sync_api import sync_playwright

SCRAPFLY_KEY = "YOUR_SCRAPFLY_API_KEY"
SCRAPFLY_URL = f"wss://browser.scrapfly.io?key={SCRAPFLY_KEY}"

with sync_playwright() as playwright:
    browser = playwright.chromium.connect_over_cdp(SCRAPFLY_URL)
    # Scrapfly returns an existing context with a default page
    context = browser.contexts[0]
    page = context.pages[0] if context.pages else context.new_page()
    page.goto("https://web-scraping.dev/products")
    print(f"Page title: {page.title()}")
    browser.close()
```



text```text
Page title: web-scraping.dev product page 1
```



Scrapfly exposes a default context with a pre-warmed page on connection, so you grab the existing page instead of calling `browser.new_page()`. Puppeteer connects the same way through its own CDP method. Selenium WebDriver does not natively attach to a remote CDP WebSocket, so Scrapfly's [Selenium guide](https://scrapfly.io/docs/cloud-browser-api/selenium) uses Playwright as the transport while keeping Selenium-style page logic.



## 2. Scrapfly Web Scraping API: Best for Scraping at Scale Without Managing a Browser

**Best for:** high-volume scraping where you need rendered output, not a live browser session.

When you need rendered HTML but not full interaction, the [Scrapfly Web Scraping API](https://scrapfly.io/products/web-scraping-api) does it in one call. It renders JavaScript, rotates proxies, geo-targets, and bypasses anti-bot, with no browser to connect or pay for by the minute.

Set `render_js=True` to run the page in a real browser and `asp=True` to clear Cloudflare, DataDome, PerimeterX, Akamai, Kasada, and 90+ other systems.

You can keep continuity with `session=`, add light interaction with `js_scenario`, return LLM-ready Markdown, and cache repeat requests. For pure unblocking, the [Scrapfly Unblocker](https://scrapfly.io/products/unblocker) wraps the same stack.

The catch is depth. For heavy click-flows or login-gated multi-step journeys, escalate to the Cloud Browser above. Treat this API as the cheaper default and the Cloud Browser as the interaction tier.

#### Code Example

python```python
from scrapfly import ScrapflyClient, ScrapeConfig

client = ScrapflyClient(key="YOUR_SCRAPFLY_API_KEY")
result = client.scrape(ScrapeConfig(
    url="https://web-scraping.dev/products",
    render_js=True,  # render the page in a real browser
    asp=True,        # bypass anti-bot protection
))
print(f"content length: {len(result.scrape_result['content'])} chars")
print(result.scrape_result["content"][:160])
```



text```text
content length: 17082 chars
<html lang="en"><head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
```



One request returns the fully rendered page, so you skip the browser lifecycle entirely. For a deeper look at API-based scraping, see our guide to the [best web scraping APIs](https://scrapfly.io/blog/posts/best-web-scraping-apis).



## 3. Scrapfly AI Browser Agent: Best for Natural-Language Browsing

**Best for:** teams that want agentic browsing without building agent infrastructure.

The [Scrapfly AI Browser Agent](https://scrapfly.io/products/ai-browser-agent) takes a goal in plain language and plans and executes the browser steps for you. It runs on the Scrapfly Cloud Browser, so it inherits the same stealth and anti-bot handling as entry #1.

Reach for it when the path through a site changes often or you would rather describe an outcome than script selectors. It fits agentic and AI pipelines where the browser is one step among many.

The downside is determinism. An agent is less predictable than scripted selectors, so for fixed, repeatable extraction a coded scraper stays more reliable. Use the agent for exploration and flexible flows, and a written scraper for stable, high-volume jobs.



## 4. Playwright: Best Open-Source Engine to Self-Host

**Best for:** teams with infrastructure capacity that want full control of their browser fleet.

[Playwright](https://playwright.dev) is the modern cross-browser automation library and the strongest open-source base for running your own browsers. It automates Chromium, Firefox, and WebKit, auto-waits for elements, and ships bindings for Python, JavaScript, Java, and .NET.

Pair it with a Playwright browser server or your own grid and you get cloud-browser-like behavior on hardware you control. Our [Playwright scraping guide](https://scrapfly.io/blog/posts/web-scraping-with-playwright-and-python) walks through the scraping basics.

The caveat is the reason managed tiers exist: you own fingerprinting, proxy rotation, anti-bot, scaling, and uptime. Playwright gives you a great engine, not a stealth browser.

#### Code Example

python```python
from playwright.sync_api import sync_playwright

with sync_playwright() as playwright:
    browser = playwright.chromium.launch(headless=True)
    page = browser.new_page()
    page.goto("https://web-scraping.dev/products")
    print(f"Page title: {page.title()}")
    browser.close()
```



text```text
Page title: web-scraping.dev product page 1
```



This launches a local Chromium and reads the page title. To run it in the cloud, you swap `launch()` for a `connect_over_cdp()` call against a hosted browser like entry #1.

**Best for:** Node teams scraping Chrome targets.

[Puppeteer](https://pptr.dev) is the Node-first library for headless Chrome and a good fit when your stack is JavaScript and Chrome-focused. It speaks CDP natively and has a large ecosystem of plugins.

Firefox support exists but stays experimental, so treat Puppeteer as Chrome-first rather than truly cross-browser. For Node scraping patterns, see our [Puppeteer guide](https://scrapfly.io/blog/posts/web-scraping-with-puppeteer-and-nodejs).

It carries the same limit as Playwright: it is an engine, not a stealth browser. You still supply proxies, fingerprint evasion, and anti-bot handling, and the API is Node-centric.



## 6. Selenium Grid: Best for Self-Hosted Multi-Language Browser Grids

**Best for:** large organizations standardized on Selenium or needing exotic language bindings.

[Selenium](https://www.selenium.dev) is the veteran standard, and Selenium Grid runs browsers across many machines in almost any language. It supports the widest set of bindings, including Python, Java, JavaScript, C#, and Ruby, on the mature WebDriver protocol.

Grid turns a pool of machines into your own distributed browser farm. Our [Selenium Grid guide](https://scrapfly.io/blog/posts/intro-to-web-scraping-using-selenium-grid) covers the setup.

The trade-off is weight: Grid is heavier and slower than Playwright, and you still own stealth, proxies, anti-bot, and operations. It earns its place on language coverage and maturity, not speed.



## 7. Browser Use: Best Open-Source Agentic Browser Framework

**Best for:** teams building their own agentic browsing on open source.

[Browser Use](https://github.com/browser-use/browser-use) is a leading open-source framework for LLM-driven browser agents. It is the do-it-yourself counterpart to the AI Browser Agent in entry #3, with roughly 109,000 GitHub stars as of August 2026. Browser Use is open-source, and its maintainer also operates a separate commercial cloud service.

It pairs with any browser backend. Point it at a local browser for development, or a managed cloud browser for stealth at scale. Our [comparison of agentic frameworks](https://scrapfly.io/blog/posts/stagehand-vs-browser-use) covers how it stacks up against the alternatives.

The cost is that you supply everything underneath: the browser infrastructure, the proxies, and the reliability layer the agent runs on. Browser Use gives you the agent logic, not the unblocked browser.



## How Cloud Browser Pricing Works

Cloud browser pricing usually follows one of three models, and knowing which you are buying matters more than the headline number.

- **Credits**: a single balance that depletes by time, bandwidth, or features used. It unifies billing but takes a little math to map to your workload.
- **Session or time based**: you pay per browser session or per minute of connection. Predictable for short tasks, but long-running sessions add up.
- **Bandwidth based**: you pay per gigabyte transferred. Browsers move a lot of data (images, CSS, scripts), so this gets hard to forecast.

Scrapfly uses a credits model and bills only for active browser time, so a crashed or idle session does not burn your balance.

Self-hosted engines like Playwright are free to install, but you pay for the servers, proxies, and anti-bot work yourself. For current tiers, see the [Scrapfly pricing page](https://scrapfly.io/pricing).



## What Scrapfly Adds Over a Plain Cloud Browser

Most cloud browsers stop at hosting the browser and leave stealth, proxies, anti-bot, and CAPTCHA to you. Scrapfly runs every session on [Scrapium](https://scrapfly.io/scrapium), a custom Chromium fork with source-level stealth, integrated residential proxies, and built-in anti-bot bypass, billed only for active browser time.

## FAQ

What is the difference between a cloud browser API and a web scraping API?A cloud browser API gives you a live browser to interact with: clicks, logins, multi-step flows. A web scraping API returns rendered HTML in one call. Use the scraping API for page content, and escalate to a cloud browser when you need real interaction.







When should I self-host Playwright or Selenium instead of using a managed cloud browser?Self-host when you have the infrastructure capacity and want full control, and you accept owning fingerprinting, proxies, anti-bot, and scaling. Use a managed cloud browser when you would rather pay to skip that operational work.







Is a cloud browser API the same as a headless browser API?Not quite, though they overlap. Headless describes a browser running without a visible interface. Cloud describes a browser running on remote infrastructure behind a network endpoint. Most cloud browser APIs run headless Chromium, which is why scraping searches treat the two terms as interchangeable.







Do cloud browsers bypass Cloudflare and DataDome?The good ones do, through built-in stealth and anti-bot handling rather than a separate plugin. Scrapfly's browsers run on Scrapium with ASP, which clears Cloudflare, DataDome, and 90+ other systems automatically.







How does cloud browser pricing usually work?Most providers bill by credits, by session or time, or by bandwidth. Scrapfly bills only for active browser time, so idle or crashed sessions do not cost you.







Can I use my existing Playwright, Puppeteer, or Selenium code with a cloud browser?For Playwright and Puppeteer, yes: you swap your local launch call for a CDP connection against the provider's WebSocket URL and the rest of your script stays the same. Selenium WebDriver does not natively attach to a remote CDP WebSocket, so Scrapfly's Selenium guide uses Playwright as the transport while keeping Selenium-style page logic.







Is using a cloud browser legal for web scraping?Running a browser in the cloud is legal, and scraping public data is generally allowed. The rules still depend on the data, the site's terms, and where you operate. Review the terms of any site you scrape and consult a professional for your specific case.









## Summary

For most teams scraping protected sites at scale, the Scrapfly Cloud Browser API is the strongest pick. It puts stealth Chromium, proxies, anti-bot, and session resume behind one CDP connection.

When you only need rendered HTML, the Web Scraping API does the same job for less, and the AI Browser Agent covers natural-language flows.

If you would rather self-host, Playwright is the best open-source engine. Puppeteer fits Node-and-Chrome stacks, and Selenium Grid handles multi-language grids.

Browser Use is the OSS choice for building your own browser agents. All four are free to run, as long as you accept owning the fingerprinting, proxies, and scaling yourself.

The fastest way to choose is to try two or three against your own targets. A managed browser and a self-hosted engine on the same protected page will show you the real cost and reliability gap in an afternoon.



Legal Disclaimer and PrecautionsThis tutorial covers popular web scraping techniques for education. Interacting with public servers requires diligence and respect:

- Do not scrape at rates that could damage the website.
- Do not scrape data that's not available publicly.
- Do not store PII of EU citizens protected by GDPR.
- Do not repurpose *entire* public datasets which can be illegal in some countries.

Scrapfly does not offer legal advice but these are good general rules to follow. For more you should consult a lawyer.
