🔥 Open Source Browser API for AI Agents & Apps. Steel Browser is a batteries-included browser sandbox that lets you automate the web without worrying about infrastructure.

Steel is an open-source browser API designed to let developers control fleets of headless browsers in the cloud. It provides a simple API endpoint to spin up on-demand browser sessions, handle CAPTCHAs automatically, and run browser automations at scale—from large-scale web scraping to fully autonomous AI agents. With over 800 billion tokens scraped and an average session start time of 1 second, Steel is built for infrastructure-heavy tasks like AI training, RPA, sales automation, QA testing, and customer service agents. The platform is batteries-included, meaning you can focus on building automations without worrying about managing browser infrastructure.
