Making a game mod can involve unpacking files, editing plugins or scripts, and assembling a package; the tools here cover different parts of that work. Compared on archive extraction, mod packaging, plugin editing, script editing, supported formats, and supported platforms, they give you several ways to check whether a tool fits your project. Minecraft Launcher, Chunker, and NetRadiant-Custom are among the entries. Free-plan availability and paid-from pricing add cost details, so consider those alongside the capabilities you need. Check formats and platforms against the game and setup you work with, then focus on the editing or packaging tasks you want the tool to handle.
24 game modding tools ranked on what their makers publish — plans and prices, free tiers, platforms and the facts on their own pages.
