Tweakeroo Mod (1.21.11, 1.20.6) – Hand Restock, Hotbar Swap

Tweakeroo is a client-side utility mod that adds dozens of quality-of-life tweaks to Minecraft, including hand restock, hotbar swap and cycle, flexible and fast block placement, free camera, and gamma override, available for Fabric and Forge across versions 1.12.2 through 26.1.

Vanilla Minecraft forces players to deal with countless small frustrations — manually restocking items from your inventory, imprecise block placement that wastes time on large builds, and visual annoyances like fog effects you cannot turn off. Tweakeroo solves all of these problems and more by packing an enormous collection of client-side tweaks into a single, configurable mod. With over 4.7 million downloads and active development by masa since 2023, it has become one of the most trusted utility mods in the Minecraft community, particularly popular among technical and redstone players.

Key Features of Tweakeroo

• Hand Restock — Automatically refills your active hand from your inventory when you run out of a block or item. This is invaluable during large building projects where constantly opening your inventory to grab more materials breaks your flow and slows you down significantly.
• Flexible & Accurate Block Placement — Lets you place blocks with far more precision than vanilla allows, including placing against air blocks and using the accurate block placement protocol introduced by Carpet mod. Builders and redstone engineers rely on this to position blocks exactly where they need them without awkward workarounds.
• Fast Left and Right Click — Automates rapid clicking at speeds impossible to achieve manually. This is particularly useful for tasks like breaking large areas of blocks or placing items quickly, saving your hands from repetitive strain during long play sessions.
• Free Camera — Detaches your camera from your player character so you can fly around and inspect builds, redstone contraptions, or terrain without moving your actual position. This feature is a game-changer for content creators filming builds and for technical players debugging complex machines.
• Gamma Override — Overrides the game's brightness setting beyond the normal slider range, effectively giving you fullbright vision. Players exploring caves or working in dark environments no longer need to spam torches just to see what they are doing.
• Hotbar Swap and Cycle — Enables quick swapping and cycling through hotbar slots with configurable keybinds. This streamlines inventory management during combat or building, allowing you to switch between tool sets without opening your inventory.
• Disable Toggles (Yeets) — A dedicated category of features that let you turn off annoying vanilla effects such as nether fog, rain particles, and other visual clutter. These toggles give you full control over your visual experience without needing separate mods for each annoyance.

How to Install Tweakeroo

1. Download and install Fabric Mod Loader for your Minecraft version. Tweakeroo primarily targets Fabric, with Forge support available for select versions.
2. Download the Tweakeroo .jar file for your specific Minecraft version from the download section below. Make sure the mod version matches your game version exactly.
3. Install MaLiLib (masa's Library mod), which is a required dependency for Tweakeroo and all of masa's mods. Place it in your mods folder alongside Tweakeroo.
4. Move both .jar files into your .minecraft/mods/ folder. On Windows, press Win+R and type %appdata%/.minecraft/mods to open the folder directly.
5. Launch Minecraft with the Fabric profile and press X + C in-game to open the Tweakeroo configuration menu, where you can enable and customize individual tweaks.

Pros and Cons

Alternatives to Tweakeroo

• Litematica — Another masa mod focused on schematic building and pasting, often used alongside Tweakeroo for the ultimate technical building setup.
• MiniHUD — A client-side HUD mod by masa that displays useful information overlays, complementing Tweakeroo's gameplay tweaks with visual data like light levels and spawn spheres.
• Inventory Profiles Next — Focuses specifically on inventory sorting and management, offering an alternative if you mainly want the hand restock and hotbar features without Tweakeroo's full scope.

Frequently Asked Questions

Is Tweakeroo safe to use on multiplayer servers?

It depends on the server's rules — Tweakeroo is a client-side mod, so it works on any server without installation, but many of its features like Flexible Block Placement and Hand Restock can trigger anti-cheat plugins. Always ask server administrators before enabling tweaks in multiplayer, as some servers explicitly ban utility mods that modify client behavior.

Does Tweakeroo work with Forge?

Yes — Tweakeroo has Forge support, but it is limited compared to the Fabric version. The Fabric edition receives the most consistent updates and supports the widest range of Minecraft versions, so Fabric is the recommended loader for the best experience with this mod.

Do I need any other mods to run Tweakeroo?

Yes — you need MaLiLib, which is masa's shared library mod required by all of his projects including Tweakeroo, Litematica, and MiniHUD. Simply download the MaLiLib version matching your Minecraft version and place it in your mods folder alongside Tweakeroo.

How do I open the Tweakeroo configuration menu?

Press X + C at the same time while in-game to open the configuration menu. From there you can browse all available tweaks and yeets (disable toggles), enable or disable individual features, and customize keybinds. If the hotkey conflicts with another mod, you can change it through the controls settings.

Will Tweakeroo affect my game performance?

Tweakeroo appears to be lightweight since it only modifies client-side behavior without adding new blocks, entities, or world generation. Individual tweaks can be toggled on and off, so you can keep only the features you actually use enabled. Most players report no noticeable performance difference with the mod installed.
