SkyMP is a free software program that is primarily distributed under the GPLv3 and AGPLv3 licenses. This means that you have significant freedom to use and distribute the program as you see fit, including sharing it with friends, making it available for download on your website, selling it, or using it as the basis for your own software project. Essentially, you can do almost anything you want with SkyMP.
While you have wide latitude to use and distribute SkyMP, there is one key requirement that must be followed: when you distribute the software in any form, you must include the full source code or a reference to where it can be obtained. Additionally, any changes you make to the source code must also be made available under the GPL. This ensures that others can benefit from and contribute to the development of SkyMP.
Each subproject within this repository has its own license, which can be found in the top-level folder for that subproject. For example, the license for the skymp5-server subproject can be found in the skymp5-server/LICENSE.md file. For full details, please be sure to read the appropriate license file for each subproject.
While it is technically possible to create a proprietary version of skymp5-client or skymp5-front that could be used with the GPL-licensed SkyMP components, this may not be the most ideal solution. Doing so may lead to compatibility issues and may disappoint users who are expecting a fully open source experience. It may be better to release any modified versions of these subprojects under a GPL-compatible license to ensure seamless integration with the rest of SkyMP.
It is important to note that SkyMP is not affiliated with or endorsed by Bethesda Softworks, ZeniMax Media, or any other rights holders. Any trademarks used in the program belong to their respective owners. SkyMP is an independent software project and should not be mistaken for an official product of any company or organization.
