Could you build this?
Partial Creating a basic LLM tracing dashboard is straightforward, but Laminar provides high-throughput real-time tracing, replay-debugging from arbitrary execution steps, and automatic unsupervised clustering of failure modes at scale.
What it would actually take: Stack typically uses Rust or Go for high-throughput OpenTelemetry trace ingestion, ClickHouse or PostgreSQL with pgvector for storing millions of spans, and Next.js for the UI. The difficult engineering challenges are building zero-overhead SDK instrumentation, state serialization for step-level replay debugging, and scalable clustering algorithms (e.g., HDBSCAN over embeddings) to identify failure signals across millions of agent runs.
