MelonLoader vs SMAPI

MelonLoader is a free mod loader for Unity games using Mono or Il2Cpp. It injects mods and supports plugins, load-order control, and dependency handling. Mods and plugins are placed in separate folders in the game installation directory, and game logs are written to a MelonLoader/Logs folder. The project provides an installer guide and manual installation instructions for a release archive. For Il2Cpp games, the listed requirement is the.NET 6.0 Desktop Runtime; the repository says it is installed automatically on Windows. Windows startup loading uses a proxy DLL, a method the project identifies as Windows-only. Linux instructions cover WINE, Steam Proton, and native use, while Android and Oculus Quest support is marked as work in progress. Debug mode is intended for work on the loader, plugins, and mods. Configuration also includes a Mono debug server, and the Il2Cpp Assembly Generator can be set to run without contacting its remote API. MelonLoader is licensed under Apache License, Version 2.0 and listed at free.

SMAPI is a mod loader for Stardew Valley, with plugin support, mod profiles, dependency handling, and load-order control. Its listed plan costs nothing. SMAPI supports Linux, macOS, Windows, Steam Deck, and Android, and is compatible with GOG and Steam achievements. The stated requirement is Stardew Valley 1.6.14 or later on Linux, macOS, Windows, or Steam Deck. Version 4.5 adds in-game configuration, performance improvements, automated and attested builds, and detection of malicious files. SMAPI.io also provides modding documentation and source code for creators, plus a mod compatibility list, log parser, JSON validator, and mod stats page. The parser can analyze and share submitted logs and show suggested fixes for common issues. The compatibility list is no longer comprehensively updated each month, and its future is uncertain. Update checks send game, SMAPI, and mod versions as well as platform type, but users can disable them. Log and JSON submissions are stored in obfuscated form for 30 days. The maker says SMAPI can be uninstalled at any time and points users to Discord and Reddit for community help.
