tracing

Telemetry is an observability platform for AI and LLM apps that tracks model calls, tool steps, retrievals, tokens, cost, latency, and errors. It supports OpenTelemetry ingest, TypeScript and Python SDKs, and integrations like Vercel AI SDK and LangChain.

Local-first debugger for LLM agent context windows. It records each call’s context into a single-file trace so you can inspect, diff, and share what the model actually saw turn by turn.

A local control plane for coding agents that gates risky actions, records structured traces, and can replay sessions under different policies.

A single-binary OpenTelemetry trace generator that simulates realistic microservice and AI-agent traces, with chaos injection and multiple topology sizes.
