Open source LLM engineering platform: LLM Observability, metrics, evals, prompt management, playground, datasets. Integrates with OpenTelemetry, Langchain, OpenAI SDK, LiteLLM, and more.
Helicone is the open-source LLM observability platform for developers to monitor, debug, and improve production-ready applications.
Opik is an open-source platform for evaluating, testing and monitoring LLM applications. Built by Comet.
Spanlens is open-source LLM observability built for application developers. Drop in a one-line proxy or SDK swap and every OpenAI, Anthropic, or Gemini call your app makes is captured with full request and response body, model, tokens, cost, and latency.
Corrath is an AI security gateway built for developers and organizations building with Large Language Models.
