Traces now support Tree and Waterfall views
Vercel ships Tree and Waterfall views for distributed tracing—critical path visibility without the context switch.
Why it matters
Vercel's tracing UI upgrade reduces friction for AI engineers debugging multi-step inference workflows and agent systems. Better observability into span timing and parallelization helps teams optimize latency-sensitive LLM pipelines.
The key facts
9 to knowTree view groups spans by parent-child hierarchy, sorted by duration
Waterfall view shows chronological timeline with parallel execution visibility
Feature integrated into Vercel Logs platform
Targets distributed tracing workflows without context-switching
Relevant for debugging agent systems and multi-step LLM inference chains
Vercel Logs now support Tree view (groups spans by parent/child, sorts by duration)
Waterfall view shows chronological span execution, reveals parallelization and bottlenecks
Feature ships in Vercel platform (July 2026)
Targets observability for full-stack AI applications
