What CC: Tweaked works with.
| Platform | Java Edition |
|---|---|
| Loaders | Fabric, Forge, NeoForge |
| Minecraft versions | 1.4.7, 1.16.5, 1.18.2, 1.19.4, 1.20.1, 1.21.1, 1.21.11, 26.1.2, 26.2 |
| Environment | Client, Server |
CC: Tweaked adds programmable, in-game computers and turtles to Minecraft Java Edition, all controlled with the Lua programming language. It runs on Fabric, Forge, and NeoForge, needs both client and server installed, and its Fabric and NeoForge builds now reach the 26.2 game version while Forge stays on 1.20.1. CC: Tweaked is a community fork that continues the original ComputerCraft mod, carrying its automation tools forward with better performance and stability.
What CC: Tweaked adds
Computers are placed blocks with a terminal you program directly in Lua, running scripts that read redstone signals, move items, or automate a base. Turtles are the mobile version, mining, placing blocks, farming, and fighting while following a program, with tool and peripheral upgrades attached to either side. Later versions add native support for reading and writing chests, tanks, and energy storage, so a computer can manage inventory systems and item sorting the way factory-automation mods like Applied Energistics 2 or Refined Storage do, just scripted instead of block-based.

- Printers for producing physical in-game pages
- An HTTP API for computers to make web requests
- Data pack support for adding ROM programs and new turtle tools
Loader and version support
CC: Tweaked publishes separate builds per loader, and they are not in lockstep. Fabric ships a stable 1.20.1 build on its release channel, plus 1.21.1 and 26.2 builds on the alpha channel. NeoForge only exists for post-1.20.1 Minecraft, and every NeoForge build the project has published, including the current 26.2 one, is labeled alpha. Forge has not moved past 1.20.1 at all; there is no Forge build for 1.21.x or the 26.x line anywhere in the project's history.
Installing CC: Tweaked
CC: Tweaked has no required dependencies, so a clean Fabric, Forge, or NeoForge instance is enough to run it. Download the build that matches your loader and Minecraft version from the Modrinth versions page, drop the jar into the mods folder, and install it on both the client and the server. Turtles and computers run their Lua scripts server-side, so a client-only install will not let a multiplayer server's computers do anything.
Learning Lua and getting started
The in-game /computercraft command lets server owners inspect and manage running computers, and the project's own documentation covers every API and peripheral in detail. Newer players often start with a video walkthrough of the terminal and basic Lua syntax before writing their own turtle programs.

Questions about CC: Tweaked.
5 questions
What is CC: Tweaked?
CC: Tweaked is a Minecraft Java mod that adds programmable computers, turtles, and peripherals you control with the Lua programming language. It lets players automate mining, farming, item sorting, and in-world displays by writing and running scripts on in-game hardware, without needing any other mod installed.
Is CC: Tweaked the same as ComputerCraft?
Not exactly. CC: Tweaked is a community fork that continues the original ComputerCraft mod created by Daniel Ratcliffe, rebuilt for newer Minecraft versions with better performance and stability. Programs written for ComputerCraft generally still work, and the mod credits that lineage rather than presenting itself as a wholly new creation.
Does CC: Tweaked work with Forge and Fabric?
Yes, though not equally. Fabric and NeoForge builds currently reach the 26.2 game version, published on the project's alpha channel, with Fabric also offering a stable 1.20.1 release build. Forge has not shipped a build newer than 1.20.1, so a Forge server on a later version needs a different loader.
Which Minecraft version does CC: Tweaked support?
CC: Tweaked's version history runs from 1.4.7 through the current 26.2 game version, one of the longer continuously maintained mod histories on Modrinth. The exact ceiling depends on loader: Fabric and NeoForge reach 26.2, while Forge stops at 1.20.1. Always match the client and server jar to the same build.
Does CC: Tweaked need any other mods installed?
No. CC: Tweaked has no required dependencies on Modrinth and runs standalone once the loader, Fabric, Forge, or NeoForge, is installed. It must be added to both the client and the server, since turtles and computers run their Lua scripts server-side while the client only renders the terminal display.
