Vercel Logs now render distributed traces in two new views: Tree and Waterfall. Developers can inspect span hierarchy, critical path, and timing data without leaving the log entry.

Tree view groups spans by parent-child relationship and sorts by duration on load, putting the slowest spans first. Waterfall view plots every span on a single chronological axis, making parallel execution and idle time immediately visible.

The full tracing documentation at vercel.com/docs/tracing covers how these views integrate into the broader observability workflow. If you are debugging latency in serverless functions or edge middleware, the Waterfall view's parallel execution mapping is the detail worth reading for.
