# Integrations

> Connect external services for tracing and observability

Bitfab integrates with popular LLM observability platforms to automatically trace your function calls. When configured, every SDK call is automatically logged to your connected services.

## Available Integrations

<CardGroup cols={2}>
  <Card title="Braintrust" icon="brain" href="#braintrust">
    Enterprise-grade LLM evaluation and monitoring
  </Card>

  <Card title="Langfuse" icon="chart-line" href="#langfuse">
    Open-source LLM observability and tracing
  </Card>
</CardGroup>

## Braintrust

[Braintrust](https://braintrust.dev) is an enterprise-grade platform for LLM evaluation, monitoring, and experimentation.

### Setup

1. Go to **Settings > Integrations** in the Bitfab portal
2. Click **Connect** on the Braintrust card
3. Enter your **API Key** (starts with `sk-`)
4. Click **Test Connection** to verify
5. Click **Save**

### What Gets Traced

When Braintrust is connected, each SDK call creates a span with:

* **Input**: The function inputs you provided
* **Output**: The parsed result from the LLM
* **Model and provider**: Which LLM was used
* **Token usage**: Input, output, and cached tokens
* **Metadata**: Function ID, version ID, and Bitfab trace ID
* **Tags**: `bitfab` and `sdk-call`

### Viewing Traces

After making SDK calls, you can view spans in your Braintrust dashboard. The Bitfab trace ID is included in the metadata for cross-referencing.

## Langfuse

[Langfuse](https://langfuse.com) is an open-source LLM observability platform that provides tracing, analytics, and prompt management.

### Setup

1. Go to **Settings > Integrations** in the Bitfab portal
2. Click **Connect** on the Langfuse card
3. Enter your credentials:
   * **Host**: Your Langfuse host (e.g., `https://cloud.langfuse.com` or your self-hosted URL)
   * **Public Key**: Your Langfuse public key (starts with `pk-lf-`)
   * **Secret Key**: Your Langfuse secret key (starts with `sk-lf-`)
4. Click **Test Connection** to verify
5. Click **Save**

### What Gets Traced

When Langfuse is connected, each SDK call creates a trace with:

* **Input**: The function inputs you provided
* **Output**: The parsed result from the LLM
* **Generation details**: Model, token usage, and timing
* **Metadata**: Function ID, version ID, and Bitfab trace ID

### Viewing Traces

After making SDK calls, you can view traces in your Langfuse dashboard. Each trace includes a direct link back to the corresponding trace in Bitfab.

## Managing Integrations

### Updating Credentials

To update an integration's credentials:

1. Go to **Settings > Integrations**
2. Click **Update** on the integration card
3. Enter new credentials
4. Click **Save**

### Disconnecting

To disconnect an integration:

1. Go to **Settings > Integrations**
2. Click **Disconnect** on the integration card
3. Confirm the disconnection

<Warning>
  Disconnecting an integration stops future traces from being sent. Existing traces in the external service are not affected.
</Warning>

## Organization Scope

Integrations are configured per organization. Each organization can have its own Langfuse and Braintrust credentials, allowing different teams to use their own observability accounts.
