Perplexity Open-Sources SPACE, a Firecracker MicroVM Sandbox for AI Agents
Perplexity has open-sourced SPACE, the sandbox platform behind every task in Perplexity Computer. The Perplexity SPACE sandbox gives each agent task its own Firecracker microVM. Credentials and outbound traffic are controlled from outside that VM. The code ships under Apache 2.0 on GitHub. For teams building coding or browsing agents, this is a production-tested isolation layer they can self-host. TL;DR Size: Rust codebase, release 0.8.0, the public baseline. HTTP API plus server-sent ev
Get smart on it
SPACE is a sandboxed platform that runs AI agent tasks in isolated microVMs, with each sandbox getting its own virtual machine and separate network gateway to control what data leaves the system. The platform matters because it provides security isolation for AI agents that need to run commands and install packages while keeping the host system protected and credentials secure. In red-team testing, the system successfully blocked all escape attempts to reach the host, though it required security fixes to prevent network policy bypasses that affected multiple competing platforms. The software is open-sourced under Apache 2.0 and requires a Linux x86_64 host with specific virtualization and filesystem capabilities to run.
