dash-ag-grid is only available in Dash Enterprise. It provides a Python interface to the Ag-Grid library, including lots of conversions from their JavaScript API into a Dash-friendly declarative Python API. We built this in collaboration with a couple of customers that had to use Ag-Grid as company policy, and decided to offer this to the rest of our customer base.
dash-ag-grid includes capabilities in the Ag-Grid community version and enterprise version. The Ag-Grid license key needs to be purchased separately to use the Ag-Grid Enterprise features. There are no plans at the moment to break this feature apart and offer portions of it for free/open source. Dash Enterprise is licensed with all of the features in one platform; individual features are not available to be licensed separately.
Note that dash-ag-grid was built on the same open source plugin framework that underpins Dash Open Source. It was important to me that these interfaces remained open source so that anyone could build anything on top of the framework; MIT licensed or otherwise! As a company, we provide dozens of features in Dash Enterprise that use this same interface. We’re always going to offer some features under the Dash Enterprise Platform license - this is the revenue that keeps the lights on and funds the development of the framework, and the rest of the ecosystem we offer for free under the MIT license.
