Value & Audience
Value Proposition
Gives teams building AI agents one trace per run with cost, latency and errors, on open OpenTelemetry plumbing, plus alerts, prompt versioning and evals, starting free.
Problem Solved
Agent runs span many model calls, tools and retrievals, which makes failures, slow steps and cost hard to pin down with ordinary logs or APM. telemetry.dev normalises AI telemetry into traces and usage views and flags anomalies.
