Vercel releases Run SDK for secure, lightweight code execution in agents
lgrammel · x · 2026-08-26
Vercel has launched the Run SDK to securely execute untrusted JavaScript and TypeScript code generated by agents. It runs code in a fresh QuickJS context within a worker thread, avoiding the need for a full sandbox for better speed and cost-efficiency. Applications can expose specific operations via hostFunctions and interrupt execution for authentication or human approval, resuming without repeating completed work.
