    40.9

    score / 100

    Why switch from Weights & Biases

    Open-source, self-hosted LLM evals and ML drift monitoring with no hosted plan required.

    Pros

    • Apache 2.0 licensed, with no paid tier needed for the core features
    • Covers both classic ML drift monitoring and LLM and agent evaluation
    • Over 100 built-in metrics, plus custom checks and LLM-as-judge
    • Evaluations run as tests, so they slot into CI pipelines

    Cons

    • Code-first Python library, so non-engineers will struggle to set up checks
    • You run and maintain the self-hosted platform yourself
    • Lighter on prompt management and production tracing than LLM-first tools
