[Opik](https://www.comet.com/site/products/opik/) is an open-source platform designed for evaluating, testing, and monitoring large language model (LLM) applications. Developed by Comet, it aims to facilitate more intuitive collaboration, testing, and monitoring of LLM-based applications.
|
|
|
|
You can configure Langflow to collect [tracing](https://www.comet.com/docs/opik/tracing/log_traces) data about your flow executions and automatically send the data to Opik.
|
|
|
|
## Prerequisites
|
|
|
|
- An [Open-Source Opik server or an Opik Cloud account](https://www.comet.com/docs/opik/faq#what-is-the-difference-between-opik-cloud-and-the-open-source-opik-platform-)
|
|
- A [running Langflow server](/get-started-installation) with a [flow](/concepts-flows) that you want to trace
|
|
|

If you need a flow to test the Opik integration, see the [Langflow quickstart](/get-started-quickstart).

## Integrate Opik with Langflow
|
|
|
|
1. If you use Opik Cloud, get an [Opik API key](https://www.comet.com/docs/opik/faq#where-can-i-find-my-opik-api-key-).
|
|
|
|
An API key isn't required with an Open-Source Opik server.
|
|
|
|
2. Call the `opik configure` CLI to save your Opik configuration in the same environment where you run Langflow:
|
|
|
|
```bash
|
|
opik configure
|
|
```
|
|
|
|
For self-hosted Opik, you can also use the following Opik CLI command:
|
|
|
|
```bash
|
|
opik configure --use_local
|
|
```
|
|
|
|
For more information, see the [Opik SDK configuration documentation](https://www.comet.com/docs/opik/tracing/sdk_configuration).
|
|
|
|
3. Start Langflow in the same terminal or environment where you set the environment variables:
|
|
|
|
```bash
|
|
uv run langflow run
|
|
```
|
|
|
|
4. In Langflow, run a flow to produce activity for Opik to trace.
|
|
|
|
5. Navigate to your Opik project dashboard and view the collected tracing data.
|
|
|
|
## Disable the Opik integration
|
|
|
|
To disable the Opik integration, remove the environment variables you set with `opik configure`, and then restart Langflow. |
