How Figma Manages Sandboxes at Scale

Figma describes Nimbus, an internal platform that manages sandboxes for AI-generated code across several cloud providers. Products request a sandbox through a configuration file, and Nimbus handles provider choice, network policy and health checks. Outside trusted hosts it allows only body-less read requests. Figma reports that warm pools cut provisioning latency by 90% and raised availability from 99% to 99.95%. These figures come from Figma itself, with no independent verification. The design lets teams swap providers without changing the product interface.
