Nov 1, 2025

In 2025-11, delivered a new CLI command to enhance deployment observability and performance diagnostics for vercel/vercel. The vercel httpstat feature introduces HTTP timing statistics for deployments, aligning with existing curl-based tooling while adding timing visualization and robust handling of protected deployments. Impact-focused highlights include improved troubleshooting capabilities for customers and faster MTTR when diagnosing latency and reliability issues across Vercel deployments. The work lays the foundation for deeper performance insights and telemetry-driven decision making. Key outcomes: - New vercel httpstat CLI command with automatic deployment URL resolution (latest or specified) and protection bypass handling. - Automatic handling of protected deployments, with header injections and secure bypass flow. - Pass-through arguments to httpstat after the -- separator, enabling flexible timing scenarios. - Full telemetry integration, comprehensive test coverage, and user-facing documentation and examples.
