tModLoader (tML) is a free program which allows playing Terraria with mods. It can be used to download mods from their database, called the Mod Browser, receive updates to mods if there are any, or upload one's own mods to the Mod Browser. It was developed and released by the tML team as a standalone program, and can also be obtained on Steam as a Terraria DLC. The official wiki, with information about creating mods and using tModLoader, can be found on GitHub.
TML is a version of the Terraria game, tweaked to allow modding. There are three versions of tModLoader: One that is based on Terraria ("1.4.4-stable"), one that is based on Terraria 1.4.3.6 ("1.4.3-legacy"), and one that is based on Terraria 1.3.5.3 ("1.3-legacy"). Mods that are available in one variant may not be available in another variant.
TML has a discord server at https://discord.gg/tmodloader (may not be accessible in all countries).
While tModLoader is endorsed by Re-Logic, none of the mods downloadable via it are officially endorsed, and thus should be treated the same as any other third-party software.

Installing multiple versions of tModLoader[]
The Steam version of Terraria and tModLoader allow for downgrading tModLoader (see Running 1.3). There may be times when you wish to have more than one version of tML installed, particularly if you find yourself switching back and forth often between the latest and an earlier version. The following instructions are for those running the Steam version wishing to install an earlier version of tML - other platforms have not been tested. These instructions assume that you have already followed the steps in Installing the latest tModLoader.

- Copy all the files from
Steam\steamapps\common\tModLoader
intoSteam\steamapps\common\tModLoaderxx

- Other tML versions (and manual 1.3 install):
- Go to the releases page and download the earlier tML release.
- Unzip the contents of the zip to the folder
Steam\steamapps\common\tModLoaderxx
(e.g. tModLoader1.3) either next to or nested inside the Terraria install folder.
- Click on the
Games
menu and clickAdd a Non-Steam Game to My Library
. - Click
Browse
... and navigate to thetModLoaderxx

Items[]
tModLoader adds some assorted items, though none of them particularly impact the game.
- The / Unloaded Item, which is used to store data for modded items that no longer have their mod present or have since been removed from their respective mods.
- The April Fools Joke, which appears to be a Terrarian but actually can be used to inflict the Wet, Lovestruck, Stinky and Slime debuffs upon the player. It can only be crafted during April Fools Day, where it displays as Terrarian...? and can be crafted with 1 Dirt Block. Removed in 1.4.4 tModLoader: https://github.com/tModLoader/tModLoader/commit/ee5d73d193ad4044f61a426354b88c2db028a273
- The Starting Bag, which is used to store excess starter items that would not fit in the player's inventory.
- Various tModLoader developer items.
