Browserbase
Browserbase provides cloud browsers, web search, fetching, and runtime tools for building and operating AI agents.
Browserbase gives developers browser sessions that AI agents can use to navigate websites, log in, interact with dynamic pages, and perform tasks. It also provides Search and Fetch APIs, agent runtime features, session observability, and model access through Stagehand.
Teams use it for browser automation, web research, monitoring, testing, and workflows that require websites without reliable APIs. The service is cloud-first and does not offer on-premises deployment. Paid plans include usage allowances, with additional browser hours, API calls, proxies, and model usage billed separately.
Features
- Run cloud browser sessions that agents can use to navigate and interact with websites
- Search the web with ranked, token-optimized results through the Search API
- Fetch web pages as HTML, JSON, or Markdown
- Deploy and run agents with Browserbase Functions
- Support logins, dynamic content, CAPTCHA solving, and persistent sessions
- Inspect sessions with recordings, replays, downloads, and dashboard observability
- Use Model Gateway for model access through Stagehand and unified billing
- Run managed browser agents from natural-language goals with one API call
Use cases
- Automate workflows across websites that do not provide usable APIs
- Research the web and return structured context to an AI agent
- Monitor prices, listings, search trends, and competitor changes
- Test customer-facing web flows continuously and detect breakages
- Fill out applications, forms, and vendor or government portals
- Run browser agents across many sites without maintaining separate scripts

Cons
Latest updates
- Introducing Stagehand 4.4: browser.disconnect(), crash-safe sessions, and more (4.4)
Disconnect from a browser and reattach later; crash-safe sessions; cross-origin iframes are more reliable.
- Navigation Policies
Define which categories of sites to allow or block, add rules for specific domains, and reuse the same policy across sessions.
- Authenticated Fetch
Fetch can now reuse saved login cookies from a Browserbase Context to retrieve pages behind a login.
- 1Password for Agents
Support for 1Password Agentic Autofill via the Browserbase extension system; credentials never pass through your application, models, or logs.
- Introducing Stagehand 4.3: OpenAI and Claude SDK integrations, page waits, and more (4.3)
Use Stagehand with the official OpenAI and Anthropic SDKs; use page.waitForFunction() to wait for application state, updated text, or another browser-side condition.
