Browserbase

Browserbase is browser agent infrastructure for AI systems that need real websites. It provides cloud browser sessions, Search and Fetch APIs, and Stagehand so agents can browse, extract, log in, and finish multi-step tasks.

Key Highlights

• Browser-as-a-Service for agents that need real browser sessions
• Search API and Fetch API for turning queries and URLs into agent context
• Stagehand SDK for AI browser workflows with Playwright-level control
• Handles auth flows, dynamic content, forms, downloads, and changing UI
• Supports high concurrency, proxies, data retention, and CAPTCHA solving
• Open source pieces include the Browser CLI and Stagehand SDK

What Makes It Different

Browserbase is built around the idea that the browser is the web's native interface. Instead of a static scrape, agents get managed browser sessions, Search API context, page fetching, model access, and runtime infrastructure.

Stagehand adds agent-friendly primitives such as act, extract, and observe, while Browserbase supplies the cloud browser sessions underneath. That pairing is useful for login walls, dynamic pages, vendor portals, forms, or UI that changes often.

Features & Capabilities

Teams create a browser session, connect a model, and run a task end to end. Browserbase works with Playwright, Puppeteer, Selenium, Stagehand, CrewAI, LangChain, and any language that can make HTTP requests.

For production use, Browserbase adds recordings, observability, Functions runtime, proxy support, model gateway billing, stealth modes, and configurable retention. Common use cases include research, QA flow checks, business verification, data extraction, form filling, and portal workflows without APIs.

User Ratings and Testimonials

Browserbase highlights customer quotes rather than an average star rating. Those quotes focus on avoiding browser infrastructure work, debugging browser fleets, and handling sites without APIs. The tradeoff is cost planning: teams need to track browser hours, Search calls, Fetch calls, proxy bandwidth, and model usage.

Pricing & Value

• Free: $0/month with 3 concurrent browsers, 1 browser hour, 1,000 Search calls, 1,000 Fetch calls, 15-minute sessions, and 7 days of retention
• Developer: $20/month with 25 concurrent browsers, 100 browser hours then $0.12/browser hour, 1,000 Search and Fetch calls, 1 GB of proxies, and auto CAPTCHA solving
• Startup: $99/month with 100 concurrent browsers, 500 browser hours then $0.10/browser hour, 10,000 Fetch calls, 5 GB of proxies, and 30 days of retention
• Scale: Custom pricing for 250+ concurrent browsers, usage-based browser hours, Search, Fetch, proxies, 30+ days of retention, verified agents, enterprise agreements, and SSO

The free plan is enough for prototypes. Developer and Startup fit production workflows that need more browser hours, API volume, proxies, or CAPTCHA handling.
