Browser Use: Pricing, Features & Alternatives

Browser Use is an open-source framework that lets an LLM operate a browser on its own. You give it a goal, and it decides the steps, scoring 89.1% on the WebVoyager benchmark, the top open-source result. That autonomy suits open-ended tasks; for repeatable workflows a primitives library like Stagehand is more predictable. Self-hosting is free (you pay your model provider), and Browser Use Cloud starts around $0.02 per browser hour (as of August 2026).
