boxlite

Boxlite gives you lightweight sandboxes. Each sandbox is a stateful micro-VM with hardware isolation, snapshots, and an API to control it. Picture giving every AI agent its own disposable computer.

The project is open source under Apache 2.0 and self-hosting is free. It's early but growing fast. The 'agent sandboxing' space is heating up as AI agents get more autonomous and need safer execution environments.

The catch: this is emerging technology. The documentation and ecosystem are still maturing. Running Firecracker-based micro-VMs requires Linux with KVM support. No macOS, no Windows natively. And the question of whether you need full VM isolation versus Docker containers depends on your threat model. For most use cases, Docker is simpler. Boxlite is for when you can't trust the code being executed.
