SPACE SPACE is Perplexity's open-source sandbox platform that assigns each AI agent task its own Firecracker microVM. Credentials and outbound network traffic stay outside the VM, enabling secure, long-running, stateful agent work with pause, fork, snapshot, and resume.

“Today, we’re open-sourcing SPACE, the project I started after joining Perplexity. I’ve had the honor of leading it with a dedicated team of engineers, supported by brilliant colleagues and leaders. I chose to work on AI because I believe safety is an engineering problem. Careful design, ambitious architecture, and high-quality craft enable us to build safer products. SPACE is the first component of our agentic runtime platform. We’re sharing it so more teams can build safer products at scale. I’m proud of what we’ve built together and grateful to everyone involved. Excited for what’s next for SPACE and Perplexity Platform.”
“I am beyond proud to open source SPACE, our sandbox platform built from the ground up to run agents securely at Perplexity scale!”
“The sandboxes that power Perplexity are now open source. It's been a lot of fun to be contributing a few spare commits in my spare time. Definitely would not have time to be actively learning a new language and rewriting our stack in Rust without today's coding agents and Perplexity's developer tooling.”
