Steel

Steel is an open-source headless browser API designed to enable developers to control fleets of browsers in the cloud. It provides the infrastructure necessary to run browser automations at scale, making it suitable for a variety of tasks from large-scale web scraping to building fully autonomous web agents. This tool is ideal for developers and organizations looking to integrate browser automation into their applications, especially those working with AI agents, foundational model training, AI shopping assistants, RPA software, sales automation, QA software, and customer service agents. Steel simplifies complex browser interactions, offering features like automatic CAPTCHA solving, proxy and browser fingerprinting management, and quick session starts to ensure smooth and efficient operations. Key benefits include the ability to spin up on-demand browser sessions via a simple API, maintain long-running sessions (up to 24 hours), and manage and reuse browser context (like cookies and local storage) to pick up automations where they left off. Its focus on speed and reliability, with average session start times under 1 second, makes it a powerful solution for high-performance browser automation needs.
