■ Steel Browser
Open-source self-hosted browser API — run your own agent browser infrastructure.
Steel is an open-source browser API agents can self-host. Provides the same programmatic browser control as managed services but without the per-session cost or vendor dependency. Good for high-volume agent deployments where economics favor self-hosting.
