Traceloop
What Traceloop is
Traceloop monitors, debugs, and evaluates applications that use large language models. It traces prompts, responses, latency, and other application activity, with monitoring and evaluation dashboards. Built-in quality checks cover faithfulness, relevance, and safety, and teams can train custom evaluators on their data. Standard and custom evaluations can run on each pull request or in real time, with thresholds to flag issues. The Free Forever plan includes up to 50,000 spans per month, five seats, and 24-hour data retention, as well as dashboards, CI/CD integration, and prompt management. Traceloop supports cloud and self-hosted deployment, including on-premises, air-gapped, restricted, and Kubernetes environments. OpenLLMetry, an open-source observability project built on OpenTelemetry, can export traces to Traceloop or another observability stack. It supports integrations across LLM providers, vector databases, frameworks, and observability platforms. OpenLLMetry can disable content tracing, recording metadata such as model name, token counts, and latency instead of prompts or responses. Traceloop states that it is SOC 2 and HIPAA compliant.
