Battly is a Minecraft launcher developed by TECNO BROS, designed to make playing and customizing the game accessible across Windows 7–11, macOS, Linux, and Android. Its focus is on security, speed, efficiency, and compatibility, with automatic cleanup and optimization intended to support performance on lower-end computers. The launcher supports Battly and Microsoft accounts and offers a range of Minecraft versions, from early releases to the latest updates, snapshots, betas, and alphas.

Players can use mod loaders and tools including Forge, Fabric, Quilt, NeoForge, LegacyFabric, and OptiFine. Battly’s instance system helps users install modpacks and keep game versions separate, while its mod management features include resource packs and shaders. Other features include skin management, customization of backgrounds, colors, and menus, and automatic Java installation.

A built-in music system lets users search for YouTube songs and create playlists while playing. Battly offers desktop and mobile downloads, along with related products called Battly Client and Battly Mobile. The site also provides tutorials, updates, support, and community channels
