Perplexity open-sources SPACE, a sandbox for running AI agent code safely

Perplexity has released SPACE, short for Sandboxed Platform for Agentic Code Execution, under the Apache 2.0 licence. It runs code from agents or users inside isolated Firecracker microVMs that an application creates, runs commands in, pauses and deletes through an HTTP API, so you do not need to write Rust to use it. It includes a compatibility layer for the E2B Python SDK, warm pools so sandboxes start without a cold boot, and a reference deployment on AWS. It needs a Linux x86_64 host with KVM and does not run directly on macOS.
