LangWatch

LangWatch is an all-in-one LLMOps platform for monitoring, observability, analytics, evaluations and alerting for getting user insights and improve your LLM workflows.

Integrate LangWatch observability​

To integrate with Langflow, add your LangWatch API key as a Langflow environment variable:

  1. Get a LangWatch API key from your LangWatch account.

  2. Add the key to your Langflow .env file:


    _10
    LANGWATCH_API_KEY="API_KEY_STRING"

    Alternatively, you can set the environment variable in your terminal session:


    _10
    export LANGWATCH_API_KEY="API_KEY_STRING"

  3. Restart Langflow with your .env file, if you modified the Langflow .env:


    _10
    langflow run --env-file .env

  4. Run a flow.

  5. View the LangWatch dashboard for monitoring and observability.

Use the LangWatch Evaluator​

In your flows, you can use the LangWatch Evaluator component to use LangWatch's evaluation endpoints to assess a model's performance.

This component is available in the LangWatch bundle in the Components menu. For more information, see Bundles.
