What it does
Open Browser is a toolkit for TypeScript developers that gives an AI agent a web browser to use. You describe a task in plain words and the agent clicks, types, scrolls and pulls out information to finish it.
It works with AI models from several providers and can run browser sessions inside a limited, sandboxed environment with resource limits.
It also offers an interactive mode where you can drive a live browser session with commands.
Who it's for
Developers who want to automate web tasks with an AI agent.
