Modrinth vs Onyx Launcher

Modrinth hosts user-created projects for Minecraft: Java Edition, including mods, plugins, data packs, shaders, resource packs, and modpacks. Search and filters help visitors find projects, including by game version. The open-source Modrinth App is a desktop launcher for installing, removing, and updating mods, and sharing modpacks. It is available for Windows, macOS, and Linux, though it is currently in public beta and Linux versions may have issues on some systems and configurations. Modrinth’s open API supports launcher integrations including ATLauncher, MultiMC, and Prism Launcher. Creators can manage team roles and permissions, receive ad revenue, and review page-view, download, and revenue reports. Modrinth Hosting supports Minecraft Java versions back to 1.2.5 and loaders including Fabric, Quilt, Forge, NeoForge, Paper, and Purpur, subject to version support. A free offer provides a 3 GB server for five days for US servers, with no credit card required. The platform has a free plan; Modrinth+ costs $4.99 a month, and customized hosting plans start at $5 a month.

Onyx Launcher is a free, open-source desktop Minecraft launcher for Windows and Linux. It manages separate instances, imports modpacks and supports Fabric, NeoForge, Forge, Quilt and Vanilla. A built-in Modrinth catalog lets users browse, install and update mods and modpacks, while automatic updates and Java runtime management are included. Onyx can detect, download and isolate Eclipse Temurin Java 8, 17 or 21 as needed. Diagnostic features measure in-game FPS, average frame times and stutters, analyze logs, track memory and garbage-collection pauses, and use Crash Bisect to look for conflicting mods through controlled launches. World Guard creates safety snapshots before risky operations and supports rollbacks. Ghost Mode unloads the launcher window, WebContents and GPU processes from memory when Minecraft starts. Microsoft sign-in uses OAuth Device Flow, and offline mode with custom skins is available. Windows builds are currently unsigned; published SHA-256 checksums can be checked. The MIT-licensed project says it is independent of Microsoft, Mojang Studios and Modrinth.
