Kernel
Cloud browser infrastructure provides managed Chromium instances that AI agents can control remotely. These platforms handle the complexity of browser lifecycle management, anti-detection, session persistence, and scaling. They are used by AI agents that need to interact with authenticated websites, fill forms, or navigate complex multi-step web workflows.

How Kernel compares
Frequently asked questions
How much does Kernel cost?
Kernel uses a freemium model, so you can start on a free tier and move to paid usage as your agent volume grows. The company does not publish a full price sheet. Paid and higher-volume plans are arranged through its pricing page or sales. Expect usage-based billing tied to browser sessions rather than fixed seats, which is the norm for browser infrastructure aimed at AI agents.
Is Kernel open source or self-hostable?
The Kernel platform is a hosted cloud service. It is not open source and cannot be self-hosted. The company does publish an open-source browser image (Kerneloss) that reflects the browser layer it runs, which is unusual transparency for this category. But the managed infrastructure, autoscaling, and anti-bot handling that you actually pay for run only on Kernel's cloud, so you cannot run the full product on your own servers.
Does Kernel handle JavaScript rendering and anti-bot detection?
Yes. Kernel runs full cloud browsers, so JavaScript-heavy pages render the way they would in a real browser. Anti-bot evasion is its headline strength. In Browser Use's independent benchmark against 71 high-security sites, Kernel scored 67 percent, ahead of Browserbase at 42 percent and Steel at 47 percent. It also offers reusable sessions and fast browser spin-up, which matter for agents hitting protected sites repeatedly.
What is Kernel best used for?
Kernel sits in the browser-infrastructure category, giving AI agents a managed cloud browser to operate the web. It fits teams building agents that must log in, click through, and complete tasks on sites with strong bot defenses, where its stealth performance pays off. It is less suited to plain structured data extraction, since it does not return structured output on its own. You pair it with your own parsing or agent logic.
How does Kernel compare to Browserbase?
Both provide cloud browsers for AI agents, but they differ on stealth. In Browser Use's independent test, Kernel reached 67 percent against high-security sites versus Browserbase's 42 percent, so Kernel is the stronger pick when sites block automation aggressively. Browserbase is more established with a wider tooling ecosystem and integrations. Choose Kernel for difficult anti-bot targets. Consider Browserbase if maturity and a broader feature set matter more than raw evasion.
What are the best alternatives to Kernel?
The closest alternatives are Browserbase, Steel.dev, and Anchor Browser, all cloud-browser platforms for AI agents. Browserbase is the most established option with broad integrations. Steel.dev offers an open-source path that Kernel's hosted platform does not match. Anchor Browser is a newer entrant in the same space. If anti-bot success rate is your priority, Kernel led the Browser Use benchmark. If you want a self-hostable base, look at Steel.
