The best browser automation framework, in every language

Stagehand v3 revolutionizes browser automation by offering a language-agnostic and driver-agnostic solution that enables developers to create robust, scalable automations without writing extensive code. It introduces a new multi-language SDK that supports Python, Java, Ruby, Rust, and Go, with alpha versions for PHP, C# .NET, and Kotlin, making browser automation accessible to a broader range of programming ecosystems. The platform is designed to work seamlessly with any browser driver, avoiding the limitations of existing AI automation libraries that are often tied to specific drivers like Playwright or Puppeteer. Stagehand's API allows for managing multiple browser sessions simultaneously using a simple session_id parameter, enabling parallel control of numerous browsers. The system is built on Stainless, facilitating consistent API implementation across different languages, and employs a high-performance Node SEA binary to maintain feature parity. By making browser automation more portable and flexible, Stagehand aims to democratize access to this essential infrastructure, transforming how testing, data pipelines, and product features are developed across diverse programming environments.
