Everest vs SMAPI

Everest is a free, open-source mod loader and modding API for Celeste. It lets players use mods with custom maps, texture replacements and code-driven additions such as sound effects, graphics, dialogue and campaigns, without changing original game files. An in-game updater and dependency downloader help manage mods. The cross-platform Olympus installer can install mods with one click from its Download Mods section or GameBanana, or from ZIP files and folders; players can also switch between Everest and vanilla Celeste through Olympus or the title screen. Everest supports Windows, macOS and Linux and works with Celeste from itch.io, Steam and Epic Games, but not the Windows Store version. Enhanced Debug Mode offers live map reloading, code and asset reload shortcuts, an improved map viewer and console logging. The project is MIT-licensed and maintained by volunteers. Olympus is actively being worked on and may fail, and the project directs users to the Celeste Discord’s #modding_help channel for bug reports and questions.

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.
