Best Browser Infrastructure for AI Agents (2026)

Getting a browser agent working locally is only the first step. As you move it into production, you’ll also need to manage browser sessions, preserve cookies and logins between tasks, avoid getting blocked, and figure out what went wrong when a run fails. More agents also mean more infrastructure to manage.

Browser infrastructure providers take much of that work off your hands by running the browsers for you. Instead of maintaining your own servers, you connect to a managed service. The choice of provider boils down to a few practical questions: how reliable is the platform, how hard is it to debug failed runs, and how much will it cost as usage grows?

In this article, we'll compare seven popular browser infrastructure providers, including Browser Use, Browserbase, and Kernel. We’ll cover their strengths, limitations, and pricing to help you choose the provider that best fits your workflow.

TL;DR

Test your shortlist on your target sites before committing. Results may vary by workflow.

What is Browser Infrastructure?

Browser infrastructure is a specialized cloud service that runs the browsers for you. By using it, you can outsource much of the annoying work of managing browsers. A provider manages the underlying servers and resources, handles browser crashes and cleanup, provides debugging tools, and lets you run many browser sessions in parallel.

Browser infrastructure is sometimes called Browsers as a Service (BaaS), not to be confused with Backend as a Service, which uses the same abbreviation.

Traditionally, browser infrastructure was used for running browser automation scripts using tools such as Selenium, Puppeteer, and Playwright. AI-powered browser agents have since become another important use case.

AI agents make capabilities such as profile persistence, cookie and session imports, human handoff, anti-bot measures, and session recovery particularly useful. These features help agents stay logged in, access target sites, and recover when a task is interrupted.

To better understand how browser infrastructure works, let's look at the typical flow:

1. You start a remote browser session via an SDK or an API.
2. The browser infrastructure provider exposes a connection endpoint, such as a Chrome DevTools Protocol WebSocket URL or a WebDriver endpoint.
3. Your automation script or an AI agent connects to the endpoint.
4. Your script or AI agent performs the task.
5. You close the remote browser session (or it happens automatically).

Choosing a Browser Infrastructure Provider

Before we look at individual providers, let’s go over the main things to consider: reliability, performance, developer experience, and cost.

Reliability

Reliability is about keeping the browser available and usable throughout a task. It combines stable browser sessions, access to target sites, and state preservation between tasks.

Features such as proxies, stealth, and CAPTCHA solving help with site access, while persistent profiles let agents reuse cookies and logins. Session recovery addresses interruptions such as dropped connections or browser crashes. Together, these capabilities reduce situations where an agent loses progress or has to start over.

Performance & Scale

Performance determines how much time the browser infrastructure adds to a task. Browser startup time affects how quickly a run can begin, while action latency affects how long the agent waits between commands. These delays become more noticeable in workflows with many sequential actions, especially when the agent and browser run in distant regions.

A good benchmark for measuring infrastructure performance is The Browser Arena.

Scale is about handling more work at once. Two limits matter here: how many browser sessions can run in parallel, and how quickly new sessions can start. A platform may have enough capacity for a steady workload but struggle with a sudden burst of tasks if session creation is limited.

Developer Experience

Developer experience covers the work involved in integrating, operating, and debugging the service. Support for familiar automation libraries, clear documentation, and useful SDKs makes it easier to connect an existing agent and manage its browser sessions.

Once the agent is running, visibility into those sessions becomes just as important. Recordings and logs help explain what happened before a failure, while live browser controls let a person step in when the agent needs help.

Cost

The total cost includes browser runtime, traffic, and any subscription fees. Minimum charges and billing increments matter for short sessions, while proxy traffic can account for much of the bill in data-heavy workflows. Failed runs and retries add usage too, so the cost of completing a task matters more than the browser-hour rate alone.

Popular Browser Infrastructure Providers

1. Browser Use

An all-around choice for AI agents, offering stealthy, affordable infrastructure.

Browser Use Infrastructure provides cloud browsers that you can control with your own agent or automation code. You can connect directly via CDP, Playwright, or Puppeteer. The platform lets you reuse browser profiles, sync local and cloud cookies, and record sessions.

Additionally, it lets you run AI-powered browser automation via Browser Use Agents, with a configurable 1Password integration for passwords and time-based one-time password (TOTP) codes.

The platform is built with stealth in mind. It features a hardened Chromium fork, solves supported CAPTCHAs automatically, and supports residential proxies.

Browser time costs $0.02/hour. Residential proxy traffic costs $5/GB; direct traffic or traffic through your own proxy costs $0.20/GB, plus any fees from your proxy provider.

Pros

• Browser infrastructure and AI agents within one platform
• Advanced stealth capabilities (Chromium fork, CAPTCHA solving, proxies)
• Supports Playwright and Puppeteer out of the box
• Usage-based pricing, no subscription required

Cons

• Browser sessions are limited to 4 hours
• Browser time rounds up to whole minutes (with a one-minute minimum)
• You must explicitly stop browsers; closing the CDP connection doesn’t end billing

2. Browserbase

A good fit for teams that prioritize debugging and inspecting browser sessions.

Browserbase provides managed browsers with live inspection, session replays, logs, and network and console information. These tools are useful when a task fails halfway through a run: you can review what happened in the browser instead of relying only on your application's error message.

You can use contexts to carry cookies and application data between sessions. For work that needs the same running browser, keep-alive lets you disconnect and reconnect later.

Browserbase also offers Stagehand, a framework for AI-powered browser automation.

The Developer plan starts at $20/month and includes 100 browser hours and 1GB of proxy traffic. Additional usage costs $0.12/browser-hour and $12/GB. The Startup plan ($99/month) includes larger allowances and lower overage rates.

Pros

• Live inspection, replays, logs, and network/console tools
• Reusable contexts for cookies and application data
• Supports Selenium, Puppeteer, and Playwright
• Specialized API endpoints for web search and page fetching

Cons

• Free plan browser sessions are limited to 15 minutes
• Advanced stealth requires the Scale plan
• Published browser-hour and proxy overage rates are higher than several alternatives

3. Kernel

A good option for fast browser actions and workflows that wait between tasks.

Kernel provides cloud browsers with headless, headful, and GPU options. Kernel advertises browser spin-up under 30 ms. In the October 1, 2026 snapshot, it led The Browser Arena's latency-only ranking. It also supports regional browsers.

One of its more useful features is standby mode. After five seconds without connected control clients or in-flight computer-control requests, a supported browser enters standby and stops accumulating usage charges.

Billing is per second, equivalent to about $0.06/hour for headless browsers and $0.48/hour for headful browsers. GPU browsers cost more. The Developer plan has no monthly subscription and includes $5 in monthly usage credits.

Pros

• Fast cloud browser spin-up and execution
• Supports headless, headful, and GPU browsers
• Open-source browser images you can run locally
• Per-second billing & standby mode

Cons

• Standby only works if no CDP, WebDriver, or live-view clients are connected; GPU browsers also don't support standby mode
• Region selection and custom proxies are gated behind subscription plans
• Developer plan is limited to 5 concurrent browsers

4. Steel

A good fit if you want an open-source browser runtime you can host yourself.

Steel Browser is an Apache-2.0-licensed browser runtime that you can host yourself. You can inspect the code, run it on your own infrastructure, or use Steel Cloud if you'd rather have the browsers managed for you.

The cloud service adds features such as managed proxies, CAPTCHA solving, and credentials management. It also provides Agent Traces, which put session activity and recordings together so you can follow what an agent did. The local version has fewer features, so check what you'll need to supply yourself before switching.

The Launch plan has no subscription and charges $0.10/browser-hour. It includes $30 in one-time credits, valid for 90 days. Scale costs $250/month, includes $100 in monthly usage credits, and lowers the browser rate to $0.08/hour.

Pros

• Apache-2.0 browser runtime with self-hosting support
• Profiles for reusing browser state
• Agent Traces and session recordings

Cons

• Browser session length is limited to 15 minutes on Launch and 60 minutes on Scale
• The listed Stealth Browser and reserved browser pools require the Enterprise plan
• Self-hosted Steel lacks built-in CAPTCHA solving, managed proxies, and the Credentials API

5. Browserless

An established option for teams with existing browser automation workloads.

Browserless provides managed browsers for Puppeteer and Playwright, along with REST APIs for tasks such as screenshots, PDFs, and scraping. You can connect your existing scripts to its cloud browsers or use BrowserQL and the BAP SDK. Its cloud service supports Chrome, Firefox, and WebKit.

For AI agents, Browserless provides MCP integration, CAPTCHA solving, and saved authentication profiles so you can reuse logins across runs. You can also inspect browser sessions live and review session replays when debugging a workflow.

Pricing starts at $25/month billed annually, with a free plan that includes 1,000 units per month. Each browser connection costs one unit per 30 seconds, rounded up. Managed proxy traffic and successful CAPTCHA solves consume additional units.

Pros

• Chrome, Firefox, and WebKit support
• MCP integration and saved authentication profiles
• Live browser interaction and session replays
• Self-hosting and private deployment options

Cons

• Sessions are limited to 2 minutes on Free, 15 minutes on Prototyping, 30 minutes on Starter, and 60 minutes on Scale
• Browser time, proxy traffic, and CAPTCHA solves consume units; reconnecting incurs a fresh unit charge
• Screen recording and custom proxies require a paid plan

6. Anchor

A useful choice when managed authentication is a central part of your workflow.

Anchor provides cloud browsers with managed authentication. Alongside browser profiles, it offers Applications and Identities to manage access to third-party services. This is useful when your agent repeatedly works inside applications that require a login.

You can inspect runs through session recordings or an interactive live browser. Enterprise customers can also deploy Anchor in their own cloud or on-premises.

Infrastructure usage costs $0.01 to create a browser, plus $0.05/browser-hour and bandwidth. Feature access depends on the plan, so check the requirements for managed authentication, proxies, and stealth before estimating the total cost.

Pros

• Managed authentication for third-party applications
• Reusable browser profiles
• Session recordings and interactive live view
• Enterprise deployment in your own cloud or on-premises

Cons

• The per-browser creation fee adds up for many short sessions
• Authentication and CAPTCHA features require a paid plan
• Custom proxies and the full stealth offering require Growth or Enterprise

7. Hyperbrowser

A useful option if you want browser infrastructure and several hosted agent choices.

Hyperbrowser offers cloud browsers alongside separately priced agent services. You can control a session with Playwright, Puppeteer, or Selenium, and use profiles to restore browser state between runs.

It supports DOM-based recordings and MP4 video, so you can review interactions or share a recording of a failed task. DOM recording is enabled by default; video recording is a separate option.

Browser usage costs $0.10/hour, billed per second, and proxy traffic costs $10/GB. The Startup plan costs $30/month and supports 25 concurrent browsers. Agent usage has its own charges, so include those if you'll use the hosted agents too.

Pros

• Playwright, Puppeteer, and Selenium integrations
• Per-second browser billing
• Profiles for reusing browser state
• DOM replay and optional video recordings

Cons

• Proxies and CAPTCHA solving require a paid plan
• Advanced stealth and custom proxies are enterprise features
• Closing all tabs stops the session, even if you intended to reconnect later

Comparison Table

Finally, let's summarize the key differences between providers in a table.

∗ Performance is based on The Browser Arena (October 1, 2026): latency-only score × 100; higher is better. It excludes reliability and does not indicate success rate or relative speed.

∗ Stealth is based on Browser Use's vendor-run benchmark (March 21, 2026): access to 71 protected sites, not task success. Browserbase used Basic Stealth; Browserless wasn't tested.

∗ Compliance is vendor-reported and depends on plan and deployment. SOC 2 is an attestation; HIPAA indicates support or BAA availability.

Conclusion

Browser Use is a good all-around choice for AI agents, combining stealth features with usage-based pricing and no required subscription. If you have a more specific priority, consider Browserbase for debugging, Kernel for speed, or Steel for an open-source runtime you can host yourself. Browserless suits existing automation workloads, while Anchor focuses on managed authentication and Hyperbrowser offers several hosted agent options.

Before committing to a provider, test your actual automation workflows on the sites you need to use. A provider that performs well on one site may struggle on another, so use these comparisons to build a shortlist, then compare success rates, speed, and cost on your own tasks.
