Yes, DevTools Installer is 100% free and open source. No hidden costs or subscriptions.

DevTools Installer is tested on Windows 11 64-bit and is compatible with both Windows 10 and Windows 11 (Home and Pro editions).

Yes, installing most developer tools (Java, Git, etc.) requires administrator access. The installer will prompt for elevation when needed.

Absolutely. The installer presents a checklist of all available tools. Select only the ones you need and choose your preferred version for each.

The installer detects existing tools on your system. You can skip already-installed tools or reinstall with a different version.

Every tool is downloaded directly from its official publisher: Oracle/Adoptium for Java, nodejs.org for Node.js, python.org for Python, etc. We never repackage or host binaries ourselves.

DevTools Installer includes a built-in one-click uninstall feature that removes the tool, cleans up PATH entries, and deletes related environment variables. You can also remove tools manually via Windows Settings → Apps & Features.

Currently, DevTools Installer supports Windows only. macOS and Linux versions are planned for a future release.

DevTools Installer is not code-signed with an EV certificate yet, so Windows SmartScreen may display a warning. Click "More info" → "Run anyway" to proceed. The application is open source and you can review the full source code on our GitHub repository.

PATH changes only apply to new terminal windows. Close all open Command Prompt, PowerShell, and VS Code terminal instances, then open a fresh one. If the issue persists, restart your computer to ensure Windows reloads environment variables.

First, check your internet connection since tools are downloaded during installation. Try running DevTools Installer as Administrator (right-click → Run as administrator). If a specific tool fails, check our guide page for that tool — the "Common Issues & Fixes" section covers the most frequent problems.

Some tools support side-by-side versions (e.g., Java JDK 21 and JDK 23). DevTools Installer lets you choose a version from the dropdown. However, tools like Node.js and Python typically use a single active version at a time. For managing multiple versions of Node.js, consider using nvm-windows alongside DevTools Installer.

DevTools Installer modifies environment variables (PATH, JAVA_HOME, etc.) through the Windows API, which writes to the registry under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment. It does not make any other registry modifications.
