Introduction

Record AI application telemetry with OpenTelemetry SDKs and standard OTLP.

telemetry.dev is an OpenTelemetry-native observability platform for AI and LLM applications. Examine model calls, tool steps, and agent runs in one trace.

What you get

The platform gives you:

Token usage, cost, latency, and errors for each trace and span.
Standard OTLP/HTTP ingest for the first-party SDKs and your OpenTelemetry stack.
Environment-level controls for input and output capture.
SDK masking and server-side redaction before storage.

The wire format is OpenTelemetry. You can keep your instrumentation and use standard OTLP instead of a proprietary trace protocol.
