Perplexity's SPACE agent sandbox

Perplexity released SPACE, the sandbox platform running every task in Perplexity Computer, as open source under the Apache 2.0 license. Each agent task runs in its own isolated Firecracker microVM, with credential management and outbound traffic controls enforced from outside the VM. Perplexity reported that SPACE processes millions of executions per day at an error rate below 0.0002%, using cryptographic identity to maintain request integrity across pause, resume, and migration events. Security testing covered 108 red-team attempts in which agents did not escape the virtual machine. Cloud partners CoreWeave, Akamai, and Crusoe have signed on to support the project, and CoreWeave has published a setup guide for evaluating SPACE on a CKS cluster. Separately, Perplexity described its Projects feature as built on a Git forge architecture, where each agent operates in its own sandbox and commits work to a shared repository, allowing humans and other agents to build on that work across sessions.
