Vercel Opens Always-on Tracing Beta

This closes a major gap between synthetic debugging and real-world diagnosis, especially for intermittent production failures. Sampling controls are the key detail: teams gain persistent visibility without accepting unlimited trace volume or cost.

• –Captures request lifecycles across Vercel infrastructure and application code
• –Supports separate sampling strategies for Production and Preview environments
• –Path-level controls let teams focus tracing on critical or error-prone routes
• –Reduces reliance on reproducing elusive bugs locally or through session-based tracing
• –OpenTelemetry compatibility keeps the feature useful alongside external observability platforms
