## Overview
|
||
|
||
This guide demonstrates how to integrate **Galileo** with **CrewAI**
|
||
for comprehensive tracing and Evaluation Engineering.
|
||
By the end of this guide, you will be able to trace your CrewAI agents,
|
||
monitor their performance, and evaluate their behaviour with
|
||
Galileo's powerful observability platform.
|
||
|
||
> **What is Galileo?** [Galileo](https://galileo.ai) is AI evaluation and observability
|
||
platform that delivers end-to-end tracing, evaluation,
|
||
and monitoring for AI applications. It enables teams to capture ground truth,
|
||
create robust guardrails, and run systematic experiments with
|
||
built-in experiment tracking and performance analytics—ensuring reliability,
|
||
transparency, and continuous improvement across the AI lifecycle.
|
||
|
||
## Getting started
|
||
|
||
This tutorial follows the [CrewAI quickstart](/en/quickstart) and shows how to add
|
||
Galileo's [CrewAIEventListener](https://v2docs.galileo.ai/sdk-api/python/reference/handlers/crewai/handler),
|
||
an event handler.
|
||
For more information, see Galileo’s
|
||
[Add Galileo to a CrewAI Application](https://v2docs.galileo.ai/how-to-guides/third-party-integrations/add-galileo-to-crewai/add-galileo-to-crewai)
|
||
how-to guide.
|
||
|
||
> **Note** This tutorial assumes you have completed the [CrewAI quickstart](/en/quickstart).
|
||
If you want a completed comprehensive example, see the Galileo
|
||
[CrewAI sdk-example repo](https://github.com/rungalileo/sdk-examples/tree/main/python/agent/crew-ai).
|
||
|
||
### Step 1: Install dependencies
|
||
|
||
Install the required dependencies for your app.
|
||
Create a virtual environment using your preferred method,
|
||
then install dependencies inside that environment using your
|
||
preferred tool:
|
||
|
||
```bash
|
||
uv add galileo
|
||
```
|
||
|
||
### Step 2: Add to the .env file from the [CrewAI quickstart](/en/quickstart)
|
||
|
||
```bash
|
||
# Your Galileo API key
|
||
GALILEO_API_KEY="your-galileo-api-key"
|
||
|
||
# Your Galileo project name
|
||
GALILEO_PROJECT="your-galileo-project-name"
|
||
|
||
# The name of the Log stream you want to use for logging
|
||
GALILEO_LOG_STREAM="your-galileo-log-stream "
|
||
```
|
||
|
||
### Step 3: Add the Galileo event listener
|
||
|
||
To enable logging with Galileo, you need to create an instance of the `CrewAIEventListener`.
|
||
Import the Galileo CrewAI handler package by
|
||
adding the following code at the top of your main.py file:
|
||
|
||
```python
|
||
from galileo.handlers.crewai.handler import CrewAIEventListener
|
||
```
|
||
|
||
At the start of your run function, create the event listener:
|
||
|
||
```python
|
||
def run():
|
||
# Create the event listener
|
||
CrewAIEventListener()
|
||
# The rest of your existing code goes here
|
||
```
|
||
|
||
When you create the listener instance, it is automatically
|
||
registered with CrewAI.
|
||
|
||
### Step 4: Run your crew
|
||
|
||
Run your crew with the CrewAI CLI:
|
||
|
||
```bash
|
||
crewai run
|
||
```
|
||
|
||
### Step 5: View the traces in Galileo
|
||
|
||
Once your crew has finished, the traces will be flushed and appear in Galileo.
|
||
|
||
|
||
|
||
## Understanding the Galileo Integration
|
||
|
||
Galileo integrates with CrewAI by registering an event listener
|
||
that captures Crew execution events (e.g., agent actions, tool calls, model responses)
|
||
and forwards them to Galileo for observability and evaluation.
|
||
|
||
### Understanding the event listener
|
||
|
||
Creating a `CrewAIEventListener()` instance is all that’s
|
||
required to enable Galileo for a CrewAI run. When instantiated, the listener:
|
||
|
||
- Automatically registers itself with CrewAI
|
||
- Reads Galileo configuration from environment variables
|
||
- Logs all run data to the Galileo project and log stream specified by
|
||
`GALILEO_PROJECT` and `GALILEO_LOG_STREAM`
|
||
|
||
No additional configuration or code changes are required.
|
||
All data from this run is logged to the Galileo project and
|
||
log stream specified by your environment configuration
|
||
(for example, GALILEO_PROJECT and GALILEO_LOG_STREAM).
