If you don't want to depend on cloud, have a mac, then you can run a sandbox locally on you mac. I have built an apple container (not docker) based sandbox to run arbitrary code - coderunner[1]. It is quite fast. And apple container provides one vm per container unlike docker on macos which shares the vm across all containers. Coderunner is good for processing sensitive docs locally in a secure sandbox.

In the coderunner read me it talks about reading files without sending them to the cloud. Does that mean there is something agentic going on? That’s more than I expect from something called a sandbox.

Also if it is agentic, why is it less cloud based than eg Claude code? Are there LLMs running locally?

		Regarding files, they are volume mapped (local <--> sandbox) as with docker. It's not agentic - agents can use it to execute code. Those agents can be powered by any LLM including local.
