Feature Compatability
Atlas is Open-Core
Atlas is an open-core project. The core engine is open-source and available on GitHub under the Apache 2.0 license. Open-source features cover the core functionality of Atlas, including database inspection, diffing, migration planning and execution, and more. For the basic and common use cases, the open-source version of Atlas is more than enough.
In addition, Atlas also offers a number of advanced features that are only available in proprietary versions. The vast majority of these features are available in the Pro Plan of Atlas, which you can use for free by creating an Atlas account.
Pro Plan
Users can upgrade to the Pro Plan for free, granting them up to 3 seats per company. After that limit, users can purchase additional seats. To learn more about our plans and pricing, visit the Atlas Pricing Page.
Create your Atlas Pro account by running the command below and following the instructions on the screen:
