Prism Launcher is a custom launcher for Minecraft that allows you to easily manage multiple installations of Minecraft at once. This is a **fork** of the MultiMC Launcher and not endorsed by MultiMC. ## Installation - All downloads and instructions for Prism Launcher can be found [on our website](https://prismlauncher.org/download/). - Last build status can be found [here](https://github.com/PrismLauncher/PrismLauncher/actions). ### Development Builds There are development builds available [here](https://github.com/PrismLauncher/PrismLauncher/actions). These have debug information in the binaries, so their file sizes are relatively larger. Portable builds are provided for Linux, Windows, and macOS.

If you have any questions or want any clarification on the above conditions please make an issue and ask us. Be aware that if you build this software without removing the provided API keys in [CMakeLists.txt](CMakeLists.txt) you are accepting the following terms and conditions: - [Microsoft Identity Platform Terms of Use](https://docs.microsoft.com/en-us/legal/microsoft-identity-platform/terms-of-use) - [CurseForge 3rd Party API Terms and Conditions](https://support.curseforge.com/en/support/solutions/articles/9000207405-curse-forge-3rd-party-api-terms-and-conditions) If you do not agree with these terms and conditions, then remove the associated API keys from the [CMakeLists.txt](CMakeLists.txt) file by setting them to an empty string (`""`). ## Sponsors & Partners We thank all the wonderful backers over at Open Collective!
