What Linen does

Everything here works on your machine without an AI subscription. Free covers the newest Minecraft version; what needs Pro is marked.

Start a mod

Mods for Fabric, Forge, NeoForge, Quilt and Legacy Fabric; plugins for Paper, Spigot, Bukkit and Purpur. Each from templates made for its era.

A shared module and a folder per version; the version switcher moves between them in one window.

Open a mod you already have, or a folder holding several versions of it, and Linen sets each one up.

Linen installs and uses the Java version each Minecraft version needs.

A block, item, recipe, loot table or missing files, written in your version's own format. You see every file first.

21 templates, from ingots and ores to swords and armour, in any colour, as real 16×16 textures.

Every block, item, mob and sound with its texture, and what each one still lacks.

Completion for targets, a preview of what an injection hooks into, and checks for targets that don't exist.

Run the client or server from Linen; the game log shows your mod's lines first with Minecraft's names readable.

Registrations, models, loot tables, names, mixins and the build, checked the way the game will, with the file and the fix.

Reads a crash report and says which mod and which line, and what to change.

The busiest methods in your mod while you play, and a mob's or block's data at a key press.

Change a texture, model or data file and see it in the running game.

Decompiled on your machine for your version. Jump into any class and find every use of a name.

Hover a name to see it in Mojang, Yarn, intermediary and Parchment.

Learn modding inside Linen; hover a name in your own code to have it explained.

Claude gets your loader, version, mappings and the rules that matter for that version.

Linen's tools let Claude look up the real API, read other mods you depend on, and run builds and tests.

Linen Check reads every file Claude changes and sends it back to fix what fails.
