Vercel Sandbox now supports memory observability
Vercel Sandbox adds memory observability—P75, P95, and CLI metrics now available to catch runaway functions before they fail.

Why it matters
Developers building on Vercel Sandbox can now measure and alert on memory usage patterns across sandboxes, closing a gap in production observability for serverless workloads. Actionable for teams running compute-intensive tasks and needing to optimize cold-start or resource ceiling risk.
