Helicone

LangChain's observability platform for monitoring, debugging, and evaluating LLM applications. Automatically traces every LLM call, captures prompts and outputs, tracks costs and latency, and enables systematic evaluation through dataset-based testing.

Comprehensive observability solution for vector databases through Zilliz Cloud integration, providing metrics for QPS, latency, slow queries, and failure rates alongside full stack monitoring.

Data observability platform specifically supporting vector databases including Pinecone, providing comprehensive monitoring across the five pillars of data observability.

Open-source LLM engineering platform providing observability, metrics, evaluations, and prompt management. Integrates with OpenTelemetry, LangChain, OpenAI SDK, and vector databases for RAG pipeline monitoring.

Open-source LLM observability tool built on OpenTelemetry standards. Automatically captures traces from LLM APIs, vector databases, and frameworks with support for over 30 popular providers.

Observability practices for vector databases including query latency, recall metrics, storage utilization, and index health monitoring.
