A modern rendering backend
The 1.8.9 core is lifted onto LWJGL 3, with code and inspiration from lwjgl3ify and MCLWJGL3. That is what lets a 2015 build cooperate with current GPU drivers and window systems.
Version 1.1.0 · Minecraft 1.8.9
A utility client that keeps 1.8.9 feeling modern.
ColdPlay is a complete client version built on an MCP 1.8.9 core with an LWJGL 3 rendering backend — so a decade-old game runs on today's drivers and today's operating systems. 39 modules, a ClickGUI, a drag-and-drop HUD editor and an alt manager, all in one JAR.

Built like a client, not a mod pack
ColdPlay ships as its own Minecraft version rather than a Forge or Fabric mod. The client, its libraries, the bundled game assets and six shared configuration profiles all arrive in one download.
Every setting one click away
Left-click a module to toggle it, right-click for its settings, middle-click to bind a key. Sliders, colour pickers, item grids and hotbar pickers are all native to the GUI.
Arrange your own overlay
Drag and scale the module list, watermark, armour status, target panel and the live rear-view Mirror. Layout is saved with the rest of your profile.
Accounts and proxies
Switch accounts from the main menu using a Microsoft token or a cracked username, with proxy support. Tokens stay in your own game directory and never ship with the client.
Six configs, already tuned
Load a profile for the mode you are actually playing instead of rebuilding settings from scratch every time.

See what the client sends
PacketLogger records every inbound and outbound packet with its origin and call site, and HumanRecorder logs camera and sent rotations per tick. Both export to CSV.
39 modules, four categories
Each one carries its own settings, an optional keybind and an Auto Off switch that disables it on death, world change or a long server teleport. Search or filter to find one.
Installation
Pick the launcher you already use. Either way you need a 64-bit Java 8 runtime.
- In Prism Launcher, click Add Instance, choose Import, and select
ColdPlay-1.8.9-Prism.zip— or paste its download link directly. - Select the ColdPlay 1.8.9 instance and click Launch. Prism downloads Java 8 and the game assets itself, and the six shared profiles are already installed.
- Press Right Shift in game to open the ClickGUI.
Do not click Revert or change the Minecraft version on the instance's Version page —
that removes ColdPlay from the instance. To update, click Folder on the instance
and replace
libraries/ColdPlay-1.8.9.jar with the new release JAR.
MultiMC is not supported.
- Launch vanilla Minecraft 1.8.9 once to download its assets, signed in with your own account, then close the game and the launcher.
- Extract
ColdPlay-1.8.9.zipinto your Minecraft game directory —%APPDATA%\.minecrafton Windows,~/.minecrafton Linux,~/Library/Application Support/minecrafton macOS. - Confirm
versions/ColdPlay-1.8.9contains both the.jarand the.json, with their names unchanged. - Reopen the launcher, enable Modded versions under Installations, create an installation
and select ColdPlay-1.8.9 with a 64-bit Java 8 runtime. On macOS, add
-XstartOnFirstThreadto that installation's JVM arguments. - Play. Press Right Shift for the ClickGUI, then open Settings to load one of the six shared profiles. Back up existing profiles before replacing them.
ColdPlay is a complete client version, not a Forge or Fabric mod. Do not put the JAR in
mods and do not replace the vanilla 1.8.9 JAR. ARM and 32-bit runtimes
are not included in the download.
- Install a Java 8 JDK and clone the repository. Gradle itself may run on a newer JVM.
- Build a release with the checked-in wrapper. Outputs land in
build/release.gradlew.bat clean verifyRelease :: Windows ./gradlew clean verifyRelease # Linux / macOS
- For development, run the client directly. Point it at your vanilla assets if they are not in the
default Windows launcher location.
gradlew.bat run gradlew.bat run "-PmcAssetsDir=C:/path/to/.minecraft/assets"
- Run the dependency-free checks in
test/coldplay/ColdPlayCheck.java— module lifecycle, config, geometry, inventory, packet recording and architecture — withgradlew.bat check. No game launch required.
