However, the existence of Eaglercraft was fraught with controversy. From an intellectual property standpoint, it was a clear violation of Mojang Studios' End User License Agreement (EULA). It distributed proprietary code for free, undermining the sales of the official game. While Mojang and Microsoft had largely tolerated the existence of fan projects and even released their own limited browser version, the scope of Eaglercraft—which allowed full access to premium features without purchase—crossed a line. Consequently, in early 2023, legal action was taken. A DMCA takedown notice resulted in the removal of the main repositories from GitHub and the shutdown of the primary domains.
As of late 2024/2025, the modding community behind Eaglercraft is pushing toward version 1.20 (Trails & Tales). However, remains the "goldilocks" version. It is modern enough to have all the cool features (Netherite, Bees, hanging signs) but is less resource-intensive than the 1.17 Caves & Cliffs part two update.
