What is Traceloop?

Editorial review
Traceloop is an LLM Reliability Platform designed to help developers ship LLM applications faster and with greater confidence. It transforms raw LLM logs into actionable insights, providing continuous feedback through evaluations and monitoring. The platform helps teams identify and resolve issues like model quality degradation and unexpected behavior before they impact users in production. Traceloop offers instant visibility into prompts, responses, and latency with minimal setup. It includes built-in quality checks for faithfulness, relevance, and safety, which are automatically applied to real data. Users can also define custom evaluators by annotating examples and training the system to score output based on their specific use cases. These evaluations can be integrated into the development pipeline, running automatically on pull requests or in real-time during app execution, ensuring quality thresholds are met and issues are caught early. The platform is built on open standards like OpenTelemetry and supports various LLM providers, vector databases, and frameworks, making it compatible with diverse tech stacks.
