UnoSDK is a powerful CLI tool for Windows that simplifies the installation and management of multiple software development kits (SDKs) from various providers. Think of it as SDKMAN for Windows - bringing the same ease of SDK management to Windows machines. Say goodbye to manual downloads, extractions, and environment variable configurations.
If you've used SDKMAN! on Linux or macOS and wished for something similar on Windows, UnoSDK is your answer. It provides a native Windows experience for managing multiple SDK versions without the complexity of manual installation and PATH management.

Automated Installation (Recommended):
Open PowerShell and run:
irm https://raw.githubusercontent.com/javaquery/unosdk/refs/heads/master/scripts/install.ps1 | iexThis will automatically:
- Download the latest release from GitHub
- Install to
%LOCALAPPDATA%\unosdk - Add unosdk to your PATH
- Replace existing installation if present
To reinstall/update unosdk:
Simply run the same command again. The script will detect the existing installation and replace it with the latest version.
- Go to the releases page
- Download the latest
unosdk.exebinary for Windows - Move the binary to a permanent location (e.g.,
C:\Program Files\unosdk\) - Add the directory to your system PATH:
# Open PowerShell and run:$path= [Environment]::GetEnvironmentVariable('Path','User')
$newPath=$path+';C:\Program Files\unosdk'
[Environment]::SetEnvironmentVariable('Path',$newPath,'User')- Verify installation:

unosdk updateUnoSDK automatically manages configuration and keeps track of installed SDKs. All data is stored in:
%USERPROFILE%\.unosdk\
├── config.yaml # User configuration
├── registry.json # Installed SDKs registry
├── cache/ # Cached SDK metadata
└── sdks/ # Installed SDKs
By default, SDKs are installed to %USERPROFILE%\.unosdk\ directory:
C:\Users\<username>\.unosdk\
├── java\
│ ├── amazoncorretto\
│ │ ├── 11\
│ │ ├── 17\
│ │ └── 21\
│ └── openjdk\
│ └── 21\
├── node\
│ └── nodejs\

├── go\
│ └── golang\
│ └── 1.23.5\
├── c\

│ └── 15.2.0\
│ └── mingw64\ # Contains bin/ (gcc), include/, lib/, etc.
└── cpp\
└── mingw\
└── 15.2.0\
└── mingw64\ # Contains bin/ (g++, gcc), include/, lib/, etc.
For example, Java Amazon Corretto 11 would be installed at:
C:\Users\<username>\.unosdk\java\amazoncorretto\11
You can customize the installation path using the --path flag when installing SDKs.
If you get "command not found" after installation, ensure:
- The directory containing
unosdk.exeis in your PATH - You've opened a new terminal window after modifying PATH
Run PowerShell or Command Prompt as Administrator when:
- Installing SDKs (to set environment variables)
- Switching between SDK versions
- First-time setup
- Verify the SDK is installed:
unosdk list --installed - Check environment variables are set correctly
- Open a new terminal to refresh environment variables
- Try switching to the SDK version:
unosdk switch <sdk-type> <provider> <version>

Special thanks to all the SDK providers for making their distributions available.
Q: Do I need to manually configure environment variables?
A: No, UnoSDK automatically configures PATH and other necessary environment variables.
Q: Can I install multiple versions of the same SDK?
A: Yes, you can install multiple versions and switch between them using unosdk switch.
Q: Where are the SDKs installed?
A: By default in %USERPROFILE%\.unosdk\ (e.g., C:\Users\<username>\.unosdk\java\amazoncorretto\11), but you can specify a custom path with --path.
Q: Is internet connection required?
A: Yes, for downloading SDKs. After installation, SDKs work offline.
Q: Can I use this alongside other SDK managers?
A: Yes, but be aware of potential PATH conflicts. UnoSDK manages its own installations independently.
