Run browsers in the cloud for automation and agent tasks.
Kernel built its service around cloud-hosted browsers so agent developers could run automation sessions without operating their own browser fleet. Its launch announcement frames those browsers as infrastructure that can be embedded into an agent’s application.
Kernel provides hosted browsers for agents that need to interact with websites. Modal gives developers a broader remote execution environment for Python and other workloads. The practical distinction is whether the team needs a browser runtime or a general application runtime.
