Persistent sandboxes are secure, isolated microVMs that retain filesystem state, installed packages, and running processes across multiple sessions.

When AI agents execute code, run shell commands, or install packages, traditional ephemeral sandboxes fall short because they discard state immediately upon completion. Persistent sandboxes solve this by automatically snapshotting and restoring the filesystem, allowing long-running agents or developer workflows to pick up exactly where they left off. Built on hardware-virtualized microVMs (using technologies like Firecracker or gVisor), these environments isolate untrusted execution at the kernel level while maintaining a continuous workspace. This architecture eliminates the latency of rebuilding environments from scratch, making it possible to run multi-stage software engineering tasks, complex data analysis, and iterative testing pipelines safely.
