Trace every LiveKit run

Full span traces

See the complete execution tree of every LiveKit run — nested spans, tool calls, and LLM requests on one timeline.

Cost & latency analytics

Track token usage, cost, and latency for every LiveKit call, broken down by model, prompt, or metadata.

Rich metadata & search

Tag, score, and search every request. Filter production traffic by content, model, status, or custom key-value pairs.

OpenTelemetry-native

LiveKit streams traces straight to PromptLayer's OTLP endpoint — no proxy in your request path, no SDK rewrite.

Debug in the playground

Open any LiveKit trace in the Playground to reproduce, tweak, and fix the exact prompt that failed.

Turn traces into evals

Promote real LiveKit runs into versioned datasets and run evaluation pipelines to catch regressions.

LLM Observability

Understand what your LiveKit app is doing

LiveKit powers real-time voice agents. PromptLayer records each session as a structured trace, so you can see exactly which turn caused a conversation to go wrong.

See the full picture

Every LiveKit run becomes a searchable, replayable trace — inputs, outputs, models, and timing.

Find the bottleneck

Pinpoint the slow span or expensive model call dragging down your LiveKit pipeline.

Catch failures fast

Surface errors, failed tool calls, and low-quality outputs before your users do.

Ship with confidence

Connect traces to evaluation pipelines so every change to your LiveKit app is tested.
