Browserbase

What it does

Browserbase takes tasks and instructions from developers and AI agents, runs them in cloud-hosted browser sessions, and returns results. Its APIs cover cloud browsers, a Search API that returns web results for a single query, and a Fetch API that converts a URL into HTML, JSON, or markdown. Outputs include page content, structured data extracted from websites, and browser session activity that can be observed.

Teams typically use it to give agents a real browser that can log in, navigate, fill forms, and pull data from sites that lack APIs, or to run recurring checks such as price, job listing, or product monitoring and end-to-end tests. Stagehand, the open-source SDK for browser agents that Browserbase maintains, lets developers write browser actions in natural language. The platform also includes Functions for deploying agents on a schedule, Agent Identity for authentication, and a Model Gateway for accessing major models under one key.

Browserbase suits developers and engineering teams building agents or automation on web data, with enterprise options for larger organizations. Access requires a Browserbase account and API key, and the sign-up page offers a free starting plan. It works with Playwright, Puppeteer, Selenium, and Stagehand. Concurrency caps and browser-hour limits vary by plan, and the platform is cloud-hosted, with VPC and private cloud options for enterprise rather than on-prem deployment.

What it can do

• Run cloud browser sessions controlled programmatically via API
• Use Playwright, Puppeteer, Selenium, or Stagehand against cloud browsers
• Search the web through a single-query Search API
• Fetch any URL as HTML, JSON, or markdown through a Fetch API
• Extract structured data from websites at scale
• Handle logins, CAPTCHAs, and multi-step forms with browser agents

Works with

• Playwright
• Puppeteer
• Selenium
• Stagehand
• LangChain
• CrewAI
• Mastra

Example workflows

Extract company data from a website

Input: a target URL and a list of fields (company, industry, location). Steps: call the Fetch API on the URL, send the returned markdown to a model with an extraction schema, save results. Output: a structured record per company, exported as CSV.

Check a login-protected portal

Input: portal URL and credentials. Steps: open a cloud browser session, let the agent log in and navigate to the target page, capture the status shown. Output: a status report of the portal page for review.

Before you choose

• Concurrency and browser-hour limits differ by plan; check the pricing page before scaling.
• Browserbase is cloud-hosted; on-prem deployment is not offered, though VPC and private cloud options are available for enterprise.
• Paid usage is metered per browser hour, Search call, Fetch call, and proxy GB, so costs grow with volume.

Get started

Free starting plan available; the docs include a quickstart.

1. Create an account at Browserbase sign-up and copy your API key from the dashboard.
2. Install an SDK or use the REST API; the Quickstart in the docs walks through a first session.
3. Create a browser session and run a first task, optionally connecting a model through Stagehand or the Model Gateway.

Start for Free includes 3 concurrent browsers, 1 browser hour, and 1,000 Search and Fetch calls. Paid tiers add per-browser-hour, per-call, and per-GB proxy metering; Enterprise is custom usage-based. Model token costs are billed at market price.
