The VMs Powering Mobile Agents (Instinct, Claude Code)
This technical analysis explores how AI agents like Claude Code utilize isolated Firecracker microVMs to run tasks securely on mobile devices. It details the architecture of these virtual machines, including how they manage disk access, process isolation, and network egress.
Why it matters
As AI agents move from local desktops to mobile environments, the security and virtualization architecture becomes critical for protecting user data and system integrity.
One awesome product evolution is that agents (Claude Code, Instinct, Poke, etc) are moving off our local computers so that we can use them on our phones. Ultimately this is great for the customer because that means the agent companies provide us with VMs for them to run on! Here's some notes on how the major platforms work based on looking around on ws-term .
Claude Code's box is its own Firecracker microVM , a KVM guest with its own kernel, booted straight into an init written in Rust:
