Mudlet is a MUD client that is available for Windows, Mac, Linux, and Chromebooks, and can be downloaded from

Support for Mudlet can be found on the Mudlet Discord server. Discord.png


Threshold has an unofficial, if useful, UI package that can be installed from within game. You can find more information on the Mudlet gui article.

UI Packages

You can add and remove UI packages in a number of ways.

Adding a package

The simplest way to add a package is to go to a website with a link to the package and drag that link onto your Mudlet character profile.

Alternatively, you can

  1. Download a package from the internet
  2. Click the Packages button in the Mudlet toolbar
  3. Click Install new package
  4. Browse for and select the package
  5. Click Open

Removing a package

Removing a package from Mudlet is as easy as

  1. Clicking on the Packages button in the Mudlet toolbar
  2. Selecting the package
  3. Clicking Remove 1 package


Depending on the package and how well it was written, you may need to restart your Mudlet to clear out any orphaned information.

Common fixes

If you have a super high DPI display and are experiencing wonky font issues, particularly in the Mudlet gui, try this fix.

Common configuration changes

Do not keep last input

Tell Mudlet to not keep the last input in your input bar by going to Settings > Input Line and ✅checking Auto clear the input line after you sent text.

Do not highlight input history text

Tell Mudlet to NOT highlight your command history text as you scroll through it by going to Settings > Input Line and ❎unchecking Highlight history.

Enable UTF-8

Most of the time, the server should tell Mudlet to enable UTF-8, but if it doesn't, you can do it manually by going to Settings > General and modifying the setting Server data encoding to UTF-8 (Recommended)

To determine if UTF-8 is working, in-game, type help utf8 and you should see some fancy rune characters that look like ᚻᛖ ᚳᚹᚫᚦ ᚦᚫᛏ ᚻᛖ ᛒᚢᛞᛖ ᚩᚾ ᚦᚫᛗ ᛚᚪᚾᛞᛖ ᚾᚩᚱᚦᚹᛖᚪᚱᛞᚢᛗ ᚹᛁᚦ ᚦᚪ ᚹᛖᛥᚫ.

Scroll-Back Enhancements

Add a script with the following line:

setConsoleBufferSize("main", 1000000, 1000)

CAUTION: If you add an enormous amount of lines, they will consume system ram over time (slowly) if your Mudlet Client stays on for months at a time. Default line length of mudlet is 10,000. The above line will increase that by 100X.
