MinePlay.io is an independent fan project that brings Minecraft-style gameplay to a web browser through Eaglercraft. Its service is free to play, requires no download, installation, launcher, Java runtime, or account, and is designed to work on Chromebooks and other devices with a WebGL-compatible browser. Players can choose survival, creative, or multiplayer modes, with three client versions available to suit different hardware and gameplay needs: 1.5.2, 1.8.8, and 1.12.

MinePlay offers locally saved worlds that players can load, rename, export as a .mpsv file, or delete. Optional accounts provide cloud backups and world syncing across devices. For multiplayer, users can join public Eaglercraft servers or share a personal world through a relay using a five-character join code, without configuring port forwarding. The site also provides server listings, shared-world discovery, guides, and FAQs. MinePlay states that it is not affiliated with Mojang Studios or Microsoft and encourages players who can purchase the official game to do so.
