surf

What it does

A Next.js app pairing OpenAI's computer-use model with E2B's cloud desktop sandbox: start a virtual machine, give instructions in plain language, and watch the agent move the mouse and type, stepping in when you want. Failures land in a throwaway environment rather than your machine. Screenshots go to the model, which is the reason not to sign into real accounts inside it, and you're billed for both model usage and sandbox uptime — shut it down when you're done. Apache-2.0.

surf FAQ

Is surf free?

surf itself is free, but it needs an API key for an external AI service. That service charges separately, though some have a free tier.

Do I need to install anything or write code to use surf?

It needs the command line. If you are not comfortable typing commands, expect to get stuck during setup.

Does surf work on a phone?

No. It needs a computer.

Can I use surf commercially?

The licence is Apache-2.0, which permits commercial use. Conditions such as keeping the copyright notice still apply, so read the licence text before shipping it inside something.
