AI agents can reason about a web task perfectly and still fail because the browser underneath them is unreliable.
Production workloads need more than a local Chromium instance. Agents may need hundreds or thousands of isolated sessions, persistent logins, CAPTCHA handling, proxies, human intervention, session replay, secure credential handling, and enough observability to understand why a run failed. That is the role of browser infrastructure.
What Browser Infrastructure Has to Handle for AI Agents
Running a few browser agents locally is relatively simple. Production changes the engineering problem.
The infrastructure layer becomes responsible for keeping many independent browser sessions available while protecting user state, maintaining access to real websites, and giving developers enough evidence to debug failures.
Important capabilities include:
- Isolated browser sessions
- Persistent authentication and profiles
- Session orchestration and concurrency
- Proxies and geographic routing
- CAPTCHA and anti-bot handling
- Playwright, Puppeteer, CDP, or Selenium compatibility
- Live session inspection
- Recordings and replay
- Human takeover
- Credential protection
- Agent framework integrations
- Private deployment options
- Reliable session cleanup and recovery
The strongest browser infrastructure does not determine what the agent wants to accomplish. It gives the agent a dependable environment in which to execute that work.
7 Best Browser Infrastructure Providers for Agentic Workflows at Scale
1. Anchor Browser - Managed Browser Infrastructure for High-Scale Agentic Workflows
Anchor Browser provides managed browser infrastructure specifically for AI agents and automation workloads that need to interact with real web applications.
The platform runs isolated Chromium environments in the cloud and exposes them through APIs, SDKs, MCP, and familiar browser automation interfaces. That allows an agent to navigate sites, fill forms, extract information, upload or download files, and perform actions where a conventional API may not exist.
Authentication is a major part of the platform. Anchor Browser's OmniConnect infrastructure is designed to manage authenticated browser workflows across sessions, including user login state and authentication methods intended for human users. This is particularly useful for agents operating business applications where logging in is part of the workflow rather than an exceptional case.
Anchor also provides its own Chromium environment and mechanisms for accessing sites that may otherwise block automated browser traffic. Networking capabilities include geographic routing, custom proxy support, and an enterprise VPN designed to provide a controlled network layer for browser agents.
For organizations running large agent fleets, the infrastructure can launch browser workloads programmatically rather than requiring teams to maintain their own Chromium cluster. Enterprise deployment options also include bring-your-own-cloud and on-premises configurations for workloads with stricter security or data requirements.
Another differentiator is the platform's approach to repeated tasks. Anchor can convert successful agent interactions into deterministic browser workflows through its Web Action Cache, reducing the amount of runtime AI reasoning needed when the same process is executed repeatedly.
Operational capabilities include live browser visibility and the ability to intervene when a workflow needs human assistance.
Anchor Browser is particularly relevant for teams moving from browser-agent prototypes to production workloads where authenticated access, browser reliability, security, and large-scale session execution all need to operate together.
2. Browserbase - Developer Platform for Agents That Act on the Web
Browserbase provides managed browsers alongside a growing collection of infrastructure and development tools for web-interacting agents.
At the browser layer, developers can create remote sessions and control them using familiar technologies such as Playwright, Puppeteer, Selenium, or Browserbase's own tooling.
Browserbase also provides persistent contexts that preserve browser state between sessions. This allows an agent to reuse cookies and application state rather than repeating authentication every time a new browser starts.
3. Kernel - Serverless Browser Infrastructure With Co-Located Agent Code
Kernel provides serverless infrastructure for browser automations and web agents, with a strong emphasis on putting application code close to the browser it controls.
Developers can launch cloud browsers on demand and preserve session state across invocations, including cookies, authentication tokens, and browsing history. This allows long-running or recurring agent workflows to continue from an existing browser state instead of starting from a clean environment each time. Kernel's architecture also supports isolated execution environments.
4. Steel - Open-Source Browser Infrastructure With Managed Cloud Deployment
Steel provides browser infrastructure for AI agents through both a managed cloud service and an open-source browser server. That combination gives teams flexibility in how much of the browser layer they want to operate themselves.
Steel Cloud provides isolated browser sessions with capabilities such as persistent profiles, proxies, CAPTCHA solving, session replay, and agent observability. Developers can connect existing AI systems or automation code using familiar browser tooling rather than adopting a proprietary agent runtime.
5. Browser Use Cloud - Cloud Browsers With Agent-Oriented Stealth and Session State
Browser Use Cloud provides remote Chromium environments designed for web agents and automation workloads. The browser infrastructure can be accessed independently from the company's open-source browser agent library, allowing teams to use Browser Use Cloud as the execution layer even when their agent logic is built elsewhere.
Sessions are CDP-compatible, which means developers can connect through standard browser tooling rather than using only the company's own agent framework.
6. Browserless - Managed and Self-Hosted Headless Browser Infrastructure
Browserless is an established browser automation infrastructure provider that supports both conventional automation and newer AI agent workloads.
The service gives developers managed headless browsers that can be controlled through Puppeteer or Playwright over WebSocket connections. REST and GraphQL APIs also support more targeted browser operations such as scraping, screenshots, and PDF generation.
7. Cloudflare Browser Run - Browser Infrastructure on a Global Edge Platform
Cloudflare Browser Run provides programmable browser sessions running on Cloudflare's global infrastructure.
The product supports direct browser control through Playwright, Puppeteer, CDP, and Stagehand, allowing teams to connect existing browser automation or agent code without rewriting the workflow around a proprietary interaction model.
