Best Minecraft Modpack Builders in 2026
Updated
In short: Prism Launcher is ranked #1 of 9 as of 3 October 2026, ahead of ATLauncher and CurseForge. The best-ranked option with a free plan is ATLauncher.
Building a Minecraft modpack means keeping mods, pack files, and the launcher workflow manageable across the people who install or host it. Compare these tools on built-in publishing, export formats, mod and pack sources, and whether they are free to use or open source. Runs-on support, server tools, and sharing by code can also shape how well a builder fits your setup. Prism Launcher, ATLauncher, and CurseForge lead the ranked entries, followed by options including Modrinth App, MultiMC, FTB App, GDLauncher, and packwiz. Check the platforms and sharing or server features your group needs, then weigh the listed publishing and export options.
