Texture Packs

Mods or Modifications are alterations to the game that provide different effects that weren't provided by the developers. Mods are generally made by fans to add things they think the game lacks, this can be anything from a program that spawns monsters to a Hot Air Balloon.

Below is a list of some of the more popular mods.

Custom Terraria Maps
Want a new challenge or just something nice to look at? There's a map for you. With 350+ maps covering adventures and quests, interesting castles, homes, multiplayer, PvP, custom dungeons, survival, gardening and farming, the list goes on.

Cmod
Cmod is a mod that adds around 5 more items, 2 more recipes, physical pipelines, and much much more. (works only for 1.0.6).

Buildaria
Buildaria offers a number of features, mainly geared towards map makers. Some of its better features are unlimited Rocket Boots, god mode, change the time of day, there is also the ability to use a "special" inventory which holds all items in the game. Downside is it's only for single-player, runs the risk of corrupting world files and deletes characters full inventory.

Obsidian's Mod
Obsidian's mod is designed to be an add-on to the original game. It adds more than 100 new items to the game, as well as new NPCs and mechanics. It also has two original bosses, with their own custom AI. The idea is not to add as much content as possible, but to enhance Terraria's gameplay through well-balanced additions. The mod is up-to-date.

Mac Wrapper
The Mac Wrapper, created by espes, is a program that allows mac users with a copy of Terraria to play almost seamlessly on Mac OS X.

Romsteady’s Terraria Launcher
This handy utility adds a bunch of features to Terraria. Firstly it allows you run the game in a larger resolution; secondly, it allows you to activate some events manually.

Mob Spawner
The Mob Spawner does just what its name implies, it allows you to spawn different mobs. It opens a version of Terraria client that allows you to spawn a pre-set mob with the touch of a button, although you can't change the mob without quitting and restarting the client. you can spawn a slime by pressing T after a while. But is very out of date and needs to be updated!

TerrariViewer
TerrariViewer allows you to edit your player's Name, HP, Mana, Appearance, Armor, Accessories, Inventory, and Piggy Bank. You can also randomize your characters colors and hair by click on their respective Randomize button on the Character Editor page but does not work on Mac so far.

TerrariViewer v6.4:

Server Browser
Server Browser allows you choose from a large list of Terraria servers. You can choose between Online, Offline, Hamachi servers, and filter empty and not empty servers.

TNT Cannon
The TNT Cannon rapidly fires Dynamite. It is designed for when you want to destroy half the map, although it could be used to find ores. Without doubt the best PvP weapon so far. This video shows how it works.

TConfig
A program that allows its user(s) add their own content to Terraria. It currently can properly program custom enemies, blocks, weapons, accesories and armor. Event, biome and map-generation/physics is not customizable yet with this program. Due to it requiring the Terraria Game Launcher, this program requires a legitimate copy of Terraria to be able to be installed.

Terraria Dedicated Server Mod
A server-side mod that predated TShock, TDSM was an alternative Terraria_Server.exe that allowed server-side console commands similar to the Source engine and Minecraft.

BloodMoon
BloodMoon is a VERY basic Terraria server wrapper. This allows you to run TerrariaServer.exe in a basic window and allows you to minimize it to the Windows System Tray as well as the Task Bar. More features could be implemented if there is great demand!
