How Grouparoo Works

We are at the next step in the data-driven evolution of how businesses scale. Over the last few years, teams have been investing by collecting key data and insights in their data warehouses to power BI and Data Science. The companies at the forefront of the Modern Data Stack movement are just starting to do Reverse ETL back to empower Marketing, Sales, and Support tools with this same data so they can make those teams more effective.

Grouparoo helps these companies scale by making integrations easy. And Grouparoo is open source, so flexibility and privacy are at the heart of the solution. Grouparoo is powered by code. You can use Grouparoo just like the rest of your tech stack; you can develop locally, commit your changes, and deploy. Our web-based user interface makes it easy to generate configuration files for even the most complex schema.

Why Open Source?

Keeping customer data secure is more important than ever


Grouparoo runs in your environment so you always have access to all the code and the data. Use it however you want.

The control and privacy features make it easier for you to comply with GDPR, CCPA, and industry-specific standards.



You get to choose exactly what data gets sent to each tool. And you give them less because it was only needed to make the groups.



Because Grouparoo is hosted in your private cloud, we’re significantly cheaper than SaaS alternatives that charge based on usage.


Features that embed in your workflow

Grouparoo makes it easy to follow developer best practices.

Pre-built integrations

All of the integration code is already written, so all of the nuances like rate limits, API requirements, and others are covered.


Charts, tools, and data to help you monitor your Grouparoo instance.


Write automated tests, so you can verify that the data is being imported and exported as you'd expect.

Many deploy options

Deploy easily using Heroku, Kubernetes, or Docker, or through your own deploy process.


Maintainable conventions so everyone on the team can easily understand and modify Grouparoo.
