Put your agent in a VM and let it be

exe.dev is a great place to run a coding agent securely, with minimal supervision. Each exe.dev VM has little access to your data (see below), except for the data that you put in it, so there's very little to exfiltrate.

As such, install your coding agent of choice, and let it do its thing, whether that be to build you a web site (that you can access directly using our HTTPS proxy) or take some screenshots or do some math or prototype some software.
