    Why switch from Galileo

    Open-source library and platform for LLM evals and monitoring, for teams that want to self-host their evaluation stack.

    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
