// EDITOR'S TAKE

Steel is the direct analogue: a self-hostable browser API with session management built specifically for agents, which is what Browserbase actually sells. Lightpanda is the pick when speed and memory per session dominate your bill, whereas Browser Use and Firecrawl solve the layer above and still need a browser to run on.
