Builder infrastructure

Browserbase

Give your agents access to the whole web

Browserbase is a cloud platform that gives AI agents real, programmable browsers so they can interact with websites the way a human would - handling logins, dynamic content, CAPTCHAs, and multi-step workflows - rather than being limited to the subset of the web that exposes an API.

Vendor's own claim

What Browserbase is

Vendor's own claim

Browserbase is browser infrastructure for AI agents: it runs real Chromium sessions in the cloud so agents can log in, click, fill forms, and scrape content on sites without a public API. It's used both directly via a REST API/SDKs and through a hosted MCP server, and it underlies the open-source Stagehand automation framework.

What it can do

Vendor's own claim

Browsers: on-demand, scalable headless browser sessions with full programmatic control
Search API: query-based web search built for agent consumption
Runtime: sandboxed, scalable deployment environments for agent code
Identity: proxying and agent authentication for human-like web navigation, plus built-in CAPTCHA solving
Agents: fully managed browser agents driven by a prompt
Model Gateway: single API key for routing to multiple LLM providers
Observability: session replays, logs, and prompt-level debugging
Stagehand: open-source browser automation framework built by Browserbase
Hosted MCP server for LLM-driven browser automation (start, navigate, act, observe, extract)

Who it is for

Vendor's own claim

Teams building AI agents or automation products that need agents to operate on arbitrary websites - covering logins, dynamic JS-heavy pages, and CAPTCHAs - rather than only on sites with a public API. Vendor case studies name Stripe, Vercel, Okta, Anthropic, Clay, Amplitude, and Ramp as customers.

When to choose something else

Our read

The Free plan gives only 1 browser-hour and 3 concurrent sessions with a 7-day data retention window, so it only works for prototyping, not production load.

Implementation considerations

Our read

Setup assessment: 30m

Creating an account and running a first session via the Node.js or Python SDK is a sub-hour task once an API key is issued. Production setup - proxy configuration, CAPTCHA handling, MCP server wiring, or Model Gateway routing - takes longer and is not a 5-minute quickstart.

Prerequisites

Browserbase account and API key
For MCP: an MCP-compatible client configured with the hosted MCP URL and API key as a query parameter

Developer and agent access

From official docs

Authentication: API key passed in the "x-bb-api-key" request header
Base URL: https://api.browserbase.com/v1/
Rate limits: Concurrency and session-creation limits vary by plan (e.g.
Machine-readable API: OpenAPI specification linked

Sessions API - create/manage/retrieve browser sessions (/v1/sessions/{sessionId})
Projects API - project-wide usage metrics
Contexts API - configure and reuse browser environments across sessions
