Windmill

Details

The project is provided under a very complex license, comprised of AGPLv3, Apache 2.0 and a “proprietary” license of unkown terms.

The license appears to potentially depend on the specific file, specific snippets within files based on flags used, and also if code that is involved in their license checks. This means you’d need to go through each file, understanding what the code is doing, to understand the licensing involved in each.

The license states that the “Community Edition” of the project includes non-public, non-FOSS code and features which are subject to extra license terms which limits use, modification and distribution.

The project advertises itself as open source on its website, including stating it’s “Fully open-source” on its homepage. It’s also self-advertised as open source in it’s GitHub description and project readme.

The project readme displays a License: AGPLv3 badge at the top of their readme, without mention of the added complexity until later in the readme.

The project appears to have received funding from investors which include YC, Gradient and Bessemer Venture Partners. The project appears to also gain revenue from providing paid variations of its software, from providing it as a service.
