What it does

The port brings the tool-crafting and smeltery content of Tinker's Construct to NeoForge, and the author notes that it was forked from the original MIT-licensed source and ported with AI assistance. Development is ongoing. The mod runs on client and server, so the server and every player need it, and it is released under the MIT License without being open source. Files exist for 1.21.1 and 26.1.2, with NeoForge 4.0.0 for 26.1.2 as the latest file.

  2. Forked original source

  3. Compatible with NeoForge Enough Items

    Works alongside NeoForge Enough Items and other libraries that the author lists as integrations.
