Traceloop

Traceloop is an observability and evaluation platform built for teams running large language model applications in production. It gives engineering teams real-time visibility into prompts, responses, latency, and cost, and layers built-in evaluators on top of that data to score outputs for qualities like faithfulness, relevance, and safety. Teams can also train custom evaluators tailored to their own quality bar, then wire automated quality gates into pull requests and production pipelines to catch regressions and LLM drift before users notice them. The platform is built on Traceloop's own open-source SDK, OpenLLMetry, which extends OpenTelemetry with LLM-specific instrumentation. It connects to more than 20 model providers including OpenAI, Anthropic, Gemini, Bedrock, and Ollama, plus vector databases such as Pinecone and Chroma, and frameworks like LangChain, LlamaIndex, and CrewAI, with SDKs for Python, TypeScript, Go, and Ruby. Traceloop can run in the cloud, on-premises, or in air-gapped environments, and lists SOC 2 and HIPAA compliance, which suits regulated enterprises. Traceloop was acquired by ServiceNow in 2026, and its technology now feeds into ServiceNow's AI governance tooling, which may shift its roadmap and pricing away from a purely standalone product. Detailed self-serve pricing is not published; the site directs prospective customers to book a demo instead.
