KRetro vs RePlayOS
Both stand on emulation frontends. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan Linux
Pick KRetro if you use Linux and want a free Libretro frontend designed for Plasma environments, with library import, controller navigation and save slots. Consider another option if metadata scraping is important, or if you need a platform other than Linux.

RePlayOS combines emulation, display options, controller support, and local-network tools for listed Raspberry Pi models. Its PC limitation and proprietary frontend restrictions are important considerations.
