Tuff Client
The Tuff builds repository currently says that releases are no longer available there and links to its Discord. The directory separately lists TuffNET as a 1.12.2 server at wss://tuff.ws. That server tag does not establish a Tuff Client feature specification or prove which fork a player must use.

The current Tuff builds README only says releases are no longer available there and points to Discord. It does not substantiate the earlier detailed claims about modern blocks, entities or below-zero terrain.
Short answer
If you searched for Tuff because a server asked for 1.12.2, you may not need Tuff at all. The project itself offers 1.12.2: open 1.12.2 (WASM-GC) on eaglercraft.com, or download the 1.12.2 ZIP from the download guide. The project describes its 1.12.2 port as still in development, says the JavaScript build is slow and says the WASM-GC build runs smoothly. Use Tuff only if a server operator tells you to.
Tuff Client, TuffNET and 1.12.2 are three different things
| Name | What it is | Where it comes from |
|---|---|---|
| Tuff Client | A separately named community client project | Builds repository on GitHub, which now says releases are no longer available there and links to Discord |
| TuffNET | A public server tagged 1.12.2 in the project directory | wss://tuff.ws; survival, SMP, OneBlock and duels in its listing |
| Eaglercraft 1.12.2 | The project's own 1.12.2 browser client | Play page (JS or WASM-GC) and two offline ZIPs in the download catalog |
| Tuff (block) | A stone block added in Minecraft 1.17 | Not related to the client; absent from 1.12.2 worlds |
What the sources establish
- TuffNET has a public directory entry and a 1.12.2 client tag. Ask the operator about any required custom client before downloading one.
- The current builds README does not substantiate modern blocks, entities, below-zero generation, FPS gains or a current Tuff release checksum.
- The project catalog independently offers a 1.12.2 client; its JS ZIP is 19,188,743 bytes. This is not a Tuff release artifact.
- Before trying a fork, export your worlds and record its base version, loader and release provenance. No Tuff build was run for this guide.
If you still want Tuff Client
- Get it only from the source the builds repository names, which is its Discord. Mirrors on unrelated sites cannot be matched to a published checksum.
- Ask in that channel which base version the build uses and whether it runs in your browser. A Chromebook may block downloads or WASM-GC.
- Keep the official 1.12.2 client as a fallback. If a fork fails to load, the not-loading guide and WASM vs JS cover the usual causes.
- To join TuffNET, add wss://tuff.ws under Multiplayer. The how-to-join guide shows the steps.
Questions
Where do I download Tuff?
The builds repo declined to host releases. This guide will not replace that with a mirror.
Do I need Tuff Client to play 1.12.2?
No. The project play page and download catalog both offer 1.12.2 directly. Use Tuff only if a server operator asks for it.
Is TuffNET the same as Tuff Client?
No. TuffNET is a server tagged 1.12.2 at wss://tuff.ws. Its directory listing does not say a custom client is required.
