**APIs profiled:** 1

StackMachine is elastic, headless infrastructure for AI applications and agents. It runs existing Node.js, Python, and PHP codebases as WebAssembly with sub-5ms cold starts and sandboxed execution for untrusted or AI-generated code, packing thousands of apps per server. The platform is driven by a single GraphQL API (api.stackmachine.com/graphql) plus official JavaScript and Python SDKs, exposing app deployment, custom domains and DNS, managed databases and volumes, cron jobs, secrets, transactional email, cloud storage, package publishing, SSH access, and usage metering. Backed by a16z.
