Give your data team magical powers

Integrate and synchronize data from 3rd party sources

Build real-time and batch pipelines to transform data using Python, SQL, and R

Run, monitor, and orchestrate thousands of pipelines without losing sleep

1️⃣ 🏗️

Build

Have you met anyone who said they loved developing in Airflow?
That’s why we designed an easy developer experience that you’ll enjoy.

Easy developer experience Start developing locally with a single command or launch a dev environment in your cloud using Terraform. Language of choice Write code in Python, SQL, or R in the same data pipeline for ultimate flexibility. Engineering best practices built-in Each step in your pipeline is a standalone file containing modular code that’s reusable and testable with data validations. No more DAGs with spaghetti code.

2️⃣ 🔮

Preview

Stop wasting time waiting around for your DAGs to finish testing.
Get instant feedback from your code each time you run it.

Interactive code Immediately see results from your code’s output with an interactive notebook UI. Data is a first-class citizen Each block of code in your pipeline produces data that can be versioned, partitioned, and cataloged for future use. Collaborate on cloud Develop collaboratively on cloud resources, version control with Git, and test pipelines without waiting for an available shared staging environment.

Launch

Don’t have a large team dedicated to Airflow?
Mage makes it easy for a single developer or small team to scale up and manage thousands of pipelines.

Fast deploy Deploy Mage to AWS, GCP, or Azure with only 2 commands using maintained Terraform templates. Scaling made simple Transform very large datasets directly in your data warehouse or through a native integration with Spark. Observability Operationalize your pipelines with built-in monitoring, alerting, and observability through an intuitive UI.

🏃‍♀️ Quick start

You can install and run Mage using Docker (recommended), pip, or conda.

Install using Docker

1. Create a new project and launch tool (change demo_project to any other name if you want):

   docker run -it -p 6789:6789 -v $(pwd):/home/src mageai/mageai \
     /app/run_app.sh mage start demo_project

   _{Want to use Spark or other integrations? Read more about integrations.}

2. Open http://localhost:6789 in your browser and build a pipeline.

Using pip or conda

1. Install Mage

   pip install mage-ai

   or

   conda install -c conda-forge mage-ai

   _{For additional packages (e.g. spark, postgres, etc), please see Installing extra packages.}

   _{If you run into errors, please see Install errors.}

2. Create new project and launch tool (change demo_project to any other name if you want):

   mage start demo_project

3. Open http://localhost:6789 in your browser and build a pipeline.

👩‍🏫 Tutorials

• Load data from API, transform it, and export it to PostgreSQL
• Integrate Mage into an existing Airflow project
• Train model on Titanic dataset
• Set up DBT models and orchestrate DBT runs

🔮 Features

🎶	Orchestration	Schedule and manage data pipelines with observability.
📓	Notebook	Interactive Python, SQL, & R editor for coding data pipelines.
🏗️	Data integrations	Synchronize data from 3rd party sources to your internal destinations.
🚰	Streaming pipelines	Ingest and transform real-time data.
❎	DBT	Build, run, and manage your DBT models with Mage.

A sample data pipeline defined across 3 files ➝

1. Load data ➝

   @data_loader
   def load_csv_from_file():
       return pd.read_csv('default_repo/titanic.csv')

2. Transform data ➝

   @transformer
   def select_columns_from_df(df, *args):
       return df[['Age', 'Fare', 'Survived']]

3. Export data ➝

   @data_exporter
   def export_titanic_data_to_disk(df) -> None:
       df.to_csv('default_repo/titanic_transformed.csv')

What the data pipeline looks like in the UI ➝

New? We recommend reading about blocks and learning from a hands-on tutorial.

🏔️ Core design principles

Every user experience and technical design decision adheres to these principles.

💻	Easy developer experience	Open-source engine that comes with a custom notebook UI for building data pipelines.
🚢	Engineering best practices built-in	Build and deploy data pipelines using modular code. No more writing throwaway code or trying to turn notebooks into scripts.
💳	Data is a first-class citizen	Designed from the ground up specifically for running data-intensive workflows.
🪐	Scaling is made simple	Analyze and process large data quickly for rapid iteration.

🛸 Core abstractions

These are the fundamental concepts that Mage uses to operate.

Project	Like a repository on GitHub; this is where you write all your code.
Pipeline	Contains references to all the blocks of code you want to run, charts for visualizing data, and organizes the dependency between each block of code.
Block	A file with code that can be executed independently or within a pipeline.
Data product	Every block produces data after it's been executed. These are called data products in Mage.
Trigger	A set of instructions that determine when or how a pipeline should run.
Run	Stores information about when it was started, its status, when it was completed, any runtime variables used in the execution of the pipeline or block, etc.
