Athina AI is a collaborative platform for building, evaluating, and monitoring LLM features. It bundles prompt management, datasets, experiments, production tracing, and a library of 50+ preset and custom evaluations, with human annotation tools on top. The platform pairs with an open-source eval SDK and works with OpenAI, Azure, Bedrock, Vertex, and custom models hosted anywhere.

    Braintrust

    Braintrust

    Hosted eval + tracing platform for LLM apps.

    Production-grade eval orchestration with a dashboard, dataset versioning, and OpenTelemetry tracing. Useful once eval volume outgrows a CI YAML file.

    LangChain

    LangChain's hosted observability + eval platform.

    Tracing, dataset management, eval orchestration, and prompt playground from the LangChain team. Pairs naturally if LangChain or LangGraph already runs in your stack, but works standalone via SDKs.

    Promptfoo

    Promptfoo

    LLM eval CLI with rubric scoring and golden sets.

    YAML-driven eval harness. Pair a prompt with a goldset, define rubrics, run across multiple models in CI. Strong for catching prompt regressions before they hit production.

    Vellum

    Build, evaluate, and deploy production LLM apps and agents.

    An end-to-end development platform for building, testing, and shipping LLM applications and agents. Vellum pairs a visual drag-and-drop workflow builder with a Python SDK, and bundles prompt versioning, RAG, evaluation, and production monitoring in one place so technical and non-technical teammates can collaborate. Built-in eval and test suites let teams measure quality before and after deploy. A free tier is available; paid Pro and Enterprise plans add seats and scale.
