Compare Prompt Versions Side By Side

via “prompt versioning and a/b testing with experiment tracking”

🪢 Open source LLM engineering platform: LLM Observability, metrics, evals, prompt management, playground, datasets. Integrates with OpenTelemetry, Langchain, OpenAI SDK, LiteLLM, and more. 🍊YC W23

Unique: Integrated prompt versioning with automatic experiment tagging via trace observations, enabling statistical analysis of prompt performance without manual data correlation or external experiment tracking tools

vs others: Combines prompt management and experiment tracking in single platform (vs separate tools like Weights & Biases or Evidently), with automatic trace-to-experiment linking avoiding manual data alignment
