Open-source, transparent alternative to OctoLauncher with improvements and new features. OctoUpdater automatically installs essential mods, recommended addons, and applies optimized client configurations — no manual AIO setup required.
Designed to be user-friendly, it brings together the knowledge and experience accumulated by the community over the years.
Can be run directly from a single Python source file with no external dependencies, or as a standalone .exe application.
Supports Windows 7+ (32-bit and 64-bit) and Linux via Proton.
