What is Perplexity SPACE (open-source agent sandbox)?

AI agents are programs that use AI to carry out tasks on their own, often by writing and running code, and even when pursuing legitimate tasks they can cross security boundaries, for example while working around a failed request or a denied permission. A common safeguard is a sandbox, a security mechanism that separates a running program from the rest of the system, usually to help keep problems from spreading. SPACE (Sandboxed Platform for Agentic Code Execution) is a sandbox platform that runs code in isolated Firecracker microVMs, small virtual machines that each have their own operating system. Other software can create and manage these environments through its web-based programming interface (an HTTP API). Perplexity open-sourced it under the Apache-2.0 license.
