AI agents are becoming increasingly capable of reasoning, planning, analyzing information, and executing multi-step tasks.

But there is one important challenge: How does an AI agent actually interact with the real web?

An LLM can generate a search query, understand instructions, summarize information, and decide what to do next. However, interacting with a modern website often requires more than generating text.

It may require opening a browser, navigating to a URL, waiting for JavaScript to load, clicking buttons, filling out forms, scrolling through pages, extracting information, and handling dynamic website content.

This is where browser infrastructure becomes an important part of AI agent development.

Instead of maintaining browser environments on their own servers, developers can use Cloud Browser Infrastructure (Browser-as-a-Service) to give their applications and AI agents access to remotely hosted browsers.

Let's explore why AI agents need browsers, how cloud browser infrastructure works, and how developers can use Agently to build browser-enabled AI applications.

1. Why AI Agents Need More Than an LLM

An AI agent is not simply a language model answering questions.

A typical agent workflow involves several stages:

  • Understanding a user's request.
  • Planning the steps required to complete a task.
  • Choosing an appropriate tool.
  • Executing actions.
  • Observing the results.
  • Deciding what to do next.

For many applications, these steps require access to external websites.

Consider an AI research assistant.

A user might ask:

"Research five project management platforms, compare their features, and summarize their pricing pages."

An LLM can reason about the task and organize the information. But it still needs a way to access those websites and retrieve their current content.

A browser provides that interaction layer.

The agent can use a browser to:

  • Open websites and navigate between pages.
  • Interact with buttons, links, and forms.
  • Read dynamically rendered content.
  • Collect information from multiple sources.
  • Capture screenshots.
  • Retrieve page content for further processing.

The distinction is important:

The AI agent provides the reasoning. The browser provides the environment for web interaction.

Without an appropriate execution environment, browser-dependent tasks become difficult to implement reliably.

2. What Is a Cloud Browser for AI Agents?

A cloud browser is a remotely hosted browser environment that applications can access over a network.

Instead of installing Chromium on your application server, configuring browser dependencies, and managing browser processes yourself, you connect to a browser running on external infrastructure.

This approach is commonly associated with Browser-as-a-Service (BaaS).

For AI agent developers, a cloud browser can serve as the execution environment through which an agent interacts with websites.

A typical architecture looks like this:

User Request → AI Agent → Browser Automation Layer → Cloud Browser → Website

The process works as follows:

  1. A user gives an AI agent a task.
  2. The agent determines which browser actions are necessary.
  3. The application connects to a remote browser.
  4. Browser automation code navigates and interacts with websites.
  5. The browser returns page content, screenshots, or other results.
  6. The agent processes the information and produces a response.

This separates AI reasoning from browser execution.

It also allows developers to focus on their application logic instead of building and maintaining all the browser infrastructure themselves.

3. The Infrastructure Challenge Behind AI Browser Automation

Building an AI agent that can interact with websites is one challenge. Operating the browser infrastructure behind it is another.

When developers build browser automation systems using locally hosted Chromium, they may need to manage:

Browser installation and configuration

Chromium and its dependencies must be installed and maintained in the execution environment.

Resource management

Browser processes consume memory and CPU resources. Multiple concurrent sessions require appropriate infrastructure planning.

Browser lifecycle management

Applications need to handle browser startup, connections, session termination, and unexpected failures.

Dynamic website rendering

Modern websites frequently depend on JavaScript frameworks and client-side rendering. Static HTML extraction may not provide the content an agent needs.

Scaling automation workloads

As the number of browser-dependent tasks increases, managing browser instances can become an additional engineering responsibility.

These challenges can take time away from developing the actual AI product.

This is why managed cloud browser infrastructure is worth considering.

4. How Agently Provides Browser Infrastructure for AI Agents

Agently is a cloud-based Browser-as-a-Service platform designed for developers, AI agents, automation systems, and LLM applications.

Its central purpose is to provide hosted Chromium browsers and web extraction tools without requiring developers to install, host, configure, and maintain their own browser infrastructure.

One of its main capabilities is the Live Browser Sandbox (Cloud Chromium).

Developers can connect to remotely hosted browser sessions through WebSocket connections and Chrome DevTools Protocol (CDP).

Agently also supports browser automation workflows using Playwright and Puppeteer.

This means developers can use familiar browser automation tools while connecting to remotely hosted browser infrastructure.

Connect Playwright to a Cloud Browser

For example, a Python application can connect to an Agently-hosted Chromium browser using Playwright:

from playwright.async_api import async_playwright async def run(): async with async_playwright() as p: browser = await p.chromium.connect_over_cdp( "wss://agently.jobdriver.org/v1/connect?apiKey=YOUR_API_KEY" ) page = await browser.new_page() await page.goto("https://example.com") print(await page.title()) await browser.close()

Replace YOUR_API_KEY with your actual API key.

In this example:

  • Playwright provides the automation interface.
  • Agently provides the remote Chromium browser.
  • The application navigates to a website.
  • The browser retrieves the page title.

The important part is that the browser does not need to run locally on the application's own server.

Developers can build on their existing Playwright workflows while using a managed browser environment.

5. What Can AI Agents Do With Cloud Browser Infrastructure?

Once an AI application has access to a browser, developers can build a variety of browser-enabled workflows.

Here are some practical examples.

AI-Powered Web Research

An AI research agent can visit multiple websites, collect relevant information, and pass the extracted content to an LLM for analysis.

A possible workflow:

  1. Receive a research question.
  2. Identify relevant websites.
  3. Open pages using a cloud browser.
  4. Extract their content.
  5. Process the information with an LLM.
  6. Generate a structured research report.

This is useful for research assistants, competitive intelligence applications, and knowledge discovery tools.

Website Interaction and Browser Automation

Some tasks require interacting with a website rather than simply reading its content.

For example, an agent might need to navigate through multiple pages, interact with forms, or click interface elements.

With a remote browser connected through Playwright or Puppeteer, developers can implement these browser actions as part of their agent workflows.

The agent decides what action is needed, while the automation layer executes it.

E-commerce Data Collection

An application could visit product pages, extract publicly available product information, and collect data such as:

  • Product names.
  • Prices.
  • Descriptions.
  • Product attributes.
  • Structured page information.

This information can then be processed by an LLM or stored in an application's database.

Website Monitoring and Visual Inspection

AI-powered applications may also need to inspect how websites look or change over time.

Browser infrastructure can support workflows involving:

  • Website screenshots.
  • Full-page captures.
  • JavaScript-rendered page inspection.
  • Visual documentation.
  • Website monitoring.

AI Knowledge Base and RAG Pipelines

AI applications that use Retrieval-Augmented Generation (RAG) need relevant external information in a format that can be processed and indexed.

A website can be crawled, its content extracted, converted into Markdown, and prepared for embedding generation and vector database storage.

This creates a practical connection between browser infrastructure, web extraction, and LLM-powered knowledge systems.

6. Browser Automation Is Only One Part: Why Web Extraction Also Matters

A cloud browser provides an execution environment, but many AI workflows also need clean and structured web content.

Extracting an entire HTML document is not always the most useful approach for an LLM.

Web pages contain navigation elements, scripts, advertisements, formatting, and other information that may not contribute to the task.

Agently combines cloud browser infrastructure with web extraction tools designed to prepare website information for applications.

Its advertised tools include:

URL to Markdown

Converts website content into clean Markdown that can be used in LLM prompts, RAG pipelines, and knowledge-processing workflows.

Article Extractor

Extracts the main content of articles and blog posts, including available title, author, and publication information.

Plain Text Extractor

Converts webpage content into readable text without unnecessary HTML formatting.

Scrape to JSON

Extracts selected website information into structured JSON using CSS selectors and supported structured data.

JavaScript HTML Renderer

Renders JavaScript-powered websites before extracting their rendered HTML and DOM content.

Website Crawler

Discovers and explores website pages recursively, supporting website indexing and content collection workflows.

These capabilities are useful because AI applications often need both website interaction and content extraction.

Rather than treating browser automation and web data extraction as completely separate problems, developers can use them as complementary parts of their architecture.

7. A Practical Architecture for an AI Browser Agent

Let's put the components together.

Imagine building an AI agent that researches competitors' websites.

A possible architecture would look like this:

Layer 1: User Interface

The user submits a research request.

Layer 2: AI Agent

The LLM interprets the request, identifies the required websites, and determines what information to collect.

Layer 3: Agent Tool and Automation Layer

The application translates the agent's decisions into browser actions using an automation framework such as Playwright.

Layer 4: Cloud Browser Infrastructure

Agently provides the remote Chromium browser through a CDP/WebSocket connection.

Layer 5: Website and Data Extraction

The browser accesses websites, while extraction tools can help convert relevant information into readable Markdown, plain text, or structured JSON.

Layer 6: AI Processing

The collected information is passed back to the LLM for comparison, summarization, or structured analysis.

The resulting architecture separates responsibilities:

  • The LLM handles reasoning and decision-making.
  • The automation framework handles browser actions.
  • The cloud browser provides the execution environment.
  • Extraction tools prepare web information.
  • The application combines the results into a useful output.

This separation makes the system easier to reason about and gives developers flexibility when designing their AI workflows.

8. When Should Developers Use a Cloud Browser?

A cloud browser is particularly worth considering when an application:

  • Needs to automate JavaScript-heavy websites.
  • Requires remote browser access.
  • Runs browser automation across multiple application environments.
  • Needs to avoid maintaining its own Chromium infrastructure.
  • Builds AI agents that interact with websites.
  • Requires screenshots or rendered page content.
  • Combines web extraction with LLM or RAG workflows.

For a small script that visits one static page occasionally, local browser automation might be sufficient.

However, when browser execution becomes a recurring infrastructure requirement, a managed cloud browser can simplify the architecture and reduce the amount of browser infrastructure developers need to maintain.

The right choice depends on workload, concurrency, reliability requirements, security, and cost.

9. Build AI Applications Without Building All the Browser Infrastructure

AI agents are becoming more useful when they can interact with external tools and real-world information.

But building an effective browser-enabled AI application requires more than an LLM.

It requires a way to access websites, execute browser actions, render dynamic pages, and retrieve information in formats that AI systems can process.

That is the problem cloud browser infrastructure is designed to address.

Agently brings together remote Chromium browser sessions, Playwright and Puppeteer connectivity, and web extraction capabilities in one developer-focused platform.

Instead of spending all your engineering effort on browser installation and infrastructure management, you can focus on the agent logic and application workflows you want to build.
