Docs corpus (Langflow->Hanzo Flow, upstream URLs langflow-ai/langflow->hanzoai/ flow, docs.langflow.org->docs.hanzo.ai), starter-project template help-URLs, CI workflows, and test files. Remaining 'langflow' repo-wide is now dominated by LANGFLOW_* env-var names + langflow_ settings fields — the config-boundary layer deliberately preserved pending a coordinated FLOW_/HANZO_ alias-with-fallback (renaming them blind breaks every deployment).

[LangWatch](https://app.langwatch.ai/) 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 Hanzo Flow, add your LangWatch API key as a Hanzo Flow environment variable:
|
|
|
|
1. Get a LangWatch API key from your LangWatch account.
|
|
|
|
2. Add the key to your Hanzo Flow `.env` file:
|
|
|
|
```shell
|
|
LANGWATCH_API_KEY="API_KEY_STRING"
|
|
```
|
|
|
|
Alternatively, you can set the environment variable in your terminal session:
|
|
|
|
```shell
|
|
export LANGWATCH_API_KEY="API_KEY_STRING"
|
|
```
|
|
|
|
3. Restart Hanzo Flow with your `.env` file, if you modified the Hanzo Flow `.env`:
|
|
|
|
```
|
|
flow 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](/components-bundle-components). |
