Traceloop
OpenTelemetry-native tracing for LLM applications

Description
Traceloop is an LLM observability company founded by Nir Gazit and Gal Kleinman, best known for OpenLLMetry, its open-source instrumentation built on OpenTelemetry. A few lines of setup emit traces for every prompt, completion, token count, and tool call, and because the data follows the OpenTelemetry standard it lands in whatever backend a team already runs. The hosted platform adds quality monitoring on top of the same traces. Instrumentation covers OpenAI, Anthropic, Bedrock, LangChain, LlamaIndex, and a long list of other providers and frameworks.
Key Capabilities:
OpenLLMetry auto-instrumentation for major LLM providers and frameworks
Standards-based traces exportable to Datadog, Grafana, Honeycomb, and others
Prompt, completion, token, and cost tracking per request
Workflow and agent tracing across multi-step chains
Quality monitors for hallucination and output drift on the hosted platform
Apache 2.0 SDKs for Python and TypeScript
