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:

   shellCopy

   LANGWATCH_API_KEY="API_KEY_STRING"
   

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

   shellCopy

   export LANGWATCH_API_KEY="API_KEY_STRING"
   

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

   Copy

   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.
