Managing model providers adds friction to every Stagehand setup. Model Gateway removes that layer by handling routing, retries, and billing at market price with no markup. Pass your Browserbase API key and pick a model—switch between OpenAI, Anthropic, and Gemini with a one-line change. No new accounts, reworked setup, or extra friction needed.
Browserbase and Prime Intellect partnered to make browser agent training more accessible. BrowserEnv, a reinforcement learning environment built on Browserbase's infrastructure, is now available at browserenv.com, providing scalable browser environments and live website access for training.
Browserbase Search, powered by Exa, enables agents to search the web with a single API call. Send a plain-text query and get back URLs your agent needs to act on next. Results return URL, title, and description (up to 25 results). Each plan includes 1,000 free searches.
Free users can now use up to 3 browsers concurrently, increased from the previous limit of 1 browser.
The Browserbase MCP server was migrated to Browserbase-managed infrastructure to improve reliability and simplify updates. MCP is now served from Browserbase-managed endpoints with improved stability for longer-running sessions. No action required for existing users.
Introducing the Fetch API for Browserbase. Provide a URL and receive the page content without requiring a browser session. Fast, cheap (~$1 per 1,000 pages), and designed for agents that need to read the web efficiently.
Stagehand now automatically caches results of repeated actions to eliminate redundant LLM calls. When encountering a page structure it's seen before, it serves the cached result instantly. Results in up to 2x faster execution and ~30% cost reduction on repeat workflows. Caching is conservative by default and scoped to your project.
Browserbase is now a one-click integration on the Vercel Agent Marketplace. Agents deployed on Vercel Sandbox can connect to remote browsers over CDP. Also launching Web Bot Auth support with Vercel, enabling agents to send cryptographically signed requests that Vercel verifies, allowing reliable browsing of Vercel-hosted deployments without security blocks.
Deploy agents and automations directly to Browserbase to run alongside their browser sessions. Define, deploy, and invoke functions while Browserbase handles execution, browser lifecycle, and results. Benefits include up to 70% faster latency, fewer moving parts, async/long-running executions with results tied to real browser sessions, and local development mirroring production. Available in TypeScript.
Session recordings rebuilt from the ground up using CDP-based screencast instead of DOM-based replay. Now offers pixel-accurate screen recordings, event-driven frame capture, asynchronous constant-time video encoding with HLS, seamless multi-tab playback, secure signed segment delivery with CDN enforcement, and just-in-time encoding for low costs and fast playback.
Stagehand v3 extends support across all languages including Python, Go, Java, Ruby, and Rust. The canonical implementation of Stagehand powered by the newest features benefits every SDK immediately, enabling faster shipping and improved extensibility. Includes revamped Python with v3 support.
Major release featuring a new foundation for Stagehand with improved speed and flexibility. Includes 20-40% speed increase across act, extract, and observe calls; compatibility with Playwright, Puppeteer, and Patchright; automatic action caching; non-AI primitives (page, locator, frameLocator, deepLocator); bun compatibility; simplified extract schemas; CSS selector support; targeted extract and observe across iframes and shadow roots; and more intuitive type names.
