Overview
telemetry.dev is an observability service for apps and agents built on language models. A single trace shows each model call, tool step and retrieval with its timing, so you can find a slow step or a failed call and see token use and cost. It also reports on MCP traffic, sends email alerts when cost or errors drift from normal, and handles prompt versions and eval runs. You connect it with its SDKs or an existing OpenTelemetry exporter, and prompt capture can be turned off per environment. Traces can include your prompts and model outputs; the site notes that redaction does not catch all sensitive data, so turn prompt capture off where you need to.
