Cursor Cloud Agents can now run in Vercel Sandbox
Cursor Cloud Agents now run in Vercel Sandbox instead of proprietary infrastructure—isolation, scale-to-zero, and durable retries baked in.
Why it matters
Agent deployment infrastructure is maturing. Cursor's shift from owned machines to Vercel's isolated compute environment signals how agent platforms are standardizing on cloud-native, ephemeral execution. Practitioners building agentic workflows now have a proven production pattern for isolation and reliability.
The key facts
5 to knowCursor Cloud Agents can execute in Vercel Sandbox (isolated Firecracker microVM per request)
