AI Agent Sandbox Runtime: The Six Options and Who Uses Them
Firecracker, gVisor, Kata, containers, V8 isolates and libkrun compared — how each isolates, what it costs in memory, and which sandbox vendors run it.

An AI agent cloud needs more than a sandbox: state, hosting, triggers, audit. I map 15 platforms against that stack and show where each one stops short.

I run the microVMs that other people's AI agents execute in. At 2 AM almost all of them are idle — and the things burning money are the robots watching them.

I shipped a doc claiming forks keep processes and open files. A smoke test proved otherwise. Three fork paths measured, and the five places each breaks.

A practical guide to picking an isolation model for AI-agent code execution, from someone who runs a Firecracker fleet: five models, five axes, one table.
