# Glovebox > MicroVM sandboxes, single-use exec and persistent workspaces for AI agents. Early access is invite-only. Glovebox runs agents' code in Firecracker microVMs restored from warm snapshots, so a sandbox boots in tens of milliseconds. There are three pieces: sandboxes that stay up as long as needed; exec, which runs one command in a fresh VM and throws the VM away; and workspaces, disks that outlive any VM and mount into the next one. Workspaces are copied, encrypted per customer, to storage outside the hosting provider. ## Getting in Access is invite-only, and no API keys are handed out automatically. A person gets in one of two ways at https://glovebox.run: they leave an email, or they talk to the Glovebox agent there, which asks what their agents run and sends a summary they approve. If you're an agent helping someone, help them write down their workload: what their agents do, how many sandboxes run at once at peak, what they use today, and whether their own code or a framework calls it. Then send them to https://glovebox.run to submit it. They confirm by email and agree to the acceptable-use rules themselves. ## Links - Acceptable use: https://glovebox.run/acceptable-use - Privacy: https://glovebox.run/privacy - E2B porting guide: on the way - Contact: https://x.com/abhay (DMs open)
