Browserbase

Freemium

Managed cloud browser infrastructure built specifically for AI agents. Provides headless Chromium instances with anti-detection, session recording, proxy rotation, and persistent session state. Not an agent itself — it's the runtime layer that Stagehand, Browser Use, and custom agent code deploy onto when local Playwright stops scaling.

// VERDICT

Reach for Browserbase when your AI agents or automation need scalable, managed cloud browsers with sessions and stealth. Skip it when local browsers suffice, you want a test framework (Playwright) rather than infrastructure, or cloud is off-limits.

Best for

Managed headless-browser infrastructure for AI agents and automation - running browsers in the cloud at scale with stealth, sessions and observability, so agents/tests have reliable browsers to drive.

Avoid when

You only run a few local browsers, you want a test framework rather than browser infra, or you can't use a cloud service.

// BEST FOR

Running headless browsers in the cloud at scale
Providing reliable browsers for AI agents to drive
Session management, stealth and observability
Offloading browser infrastructure from your app
Integrating with agent frameworks (e.g. Stagehand)
Scaling automation without managing browser fleets

// AVOID WHEN

You only need a few local browsers
You want a test framework, not browser infrastructure
Cloud services are off-limits
Cost of managed browsers isn't justified
Deterministic local runs are all you need
You're not running agents/automation at scale

// QUICK START

Use the Browserbase SDK/API to launch a cloud browser session -> connect your
agent or automation (e.g. Playwright/CDP) to it -> run at scale with managed
sessions, stealth and observability.

// ALTERNATIVES TO CONSIDER

Tool	Choose it when
Stagehand	You want the AI automation framework that runs on top of cloud browsers.
Browser Use	You want an open-source agent to drive browsers.
Playwright	You want a local/standard browser automation framework.

// FEATURES

Managed headless Chrome instances with API control
Session recordings — replay exactly what an agent did, useful for debugging non-deterministic failures
Stealth mode and proxy rotation for sites with active bot detection
Playwright and Puppeteer compatible — drop-in replacement for local browser instances
Native Stagehand integration via Functions for zero-infrastructure deployment

// PROS

Removes the proxy/anti-detection/scaling work most teams don't want to own
Session replay is genuinely useful for debugging agent failures — better than reading traces
Under 100 browser-hours per month, self-hosted Playwright still wins on cost

// CONS

Closed-source managed service — vendor lock-in for the runtime layer
Costs scale with browser-hours; high-volume scraping gets expensive fast
Not a browser agent itself — you still need Stagehand, Browser Use, or custom code on top
