Browserbase + Stagehand Guide

What it does

Browserbase supplies the infrastructure, a remote virtual machine running the browser, while Stagehand is the developer framework on top that turns natural-language instructions into actual clicks and inputs. Together they let you run browser automation at scale without hosting the servers yourself.

This role has the AI open websites, click buttons, and fill out forms itself, taking over work a person would normally do with a mouse and keyboard.

When it fits

It fits development teams writing TypeScript or Python who need to scale concurrent browser sessions up and down as demand changes. It also suits teams who want to run automation without being limited by local machine resources, since the virtual browser runs entirely remote.

When it doesn't fit

The limitations below come from the vendor's own official documentation, not our evaluation. As of 2026-09-22

Automatic CAPTCHA solving only works for workflows the site owner has authorized, and unsupported CAPTCHA types require you to supply CSS selectors by hand. The free plan is capped at 3 concurrent browsers and 5 new sessions per minute, and requests beyond that are rejected. Stagehand itself is a developer framework you write in TypeScript or Python, and it only works on Chromium-based browsers.

Compare with

Browser Use is an open-source framework you install and run yourself, and Playwright MCP gives code-level precision through the MCP protocol. Browserbase + Stagehand differs from both by renting the virtual browser infrastructure itself remotely, so the choice comes down to how much infrastructure operation you want to hand off.
