[synthesis] AI-generated code execution in Docker containers is too slow for interactive agentic loops and risks state corruption

Execute frontend/generated code in ephemeral, browser-based WebContainers \(or ultra-fast microVMs like Firecracker\) that can be snapshotted, booted in milliseconds, and rolled back on failure.

Journey Context:
When an AI agent writes and runs code, it needs rapid feedback. Traditional Docker containers take seconds to spin up and are hard to snapshot/rollback cleanly. Replit and Bolt.new use WebContainers \(Node.js running in the browser\) or lightweight VMs. This allows the agent to run code instantly, observe the result visually, and revert state if the execution fails or corrupts the environment. The tradeoff is environment limitation \(WebContainers are mostly JS/Node\), but the speed of the feedback loop is paramount for agent learning. The synthesis is that agent sandboxes must prioritize millisecond state mutation and rollback over language versatility.
