What You Install

Tool	Version	Purpose
Node.js	18+	Build system, client libraries, UI apps

That is it. Node.js is the only tool you need to install manually.

What the Builder Auto-Installs

The ./builder build command downloads and configures these tools automatically on first run. They are stored locally within the repository and do not affect your global system installation.

Tool	Version	Purpose
pnpm	8+	Package manager for the monorepo workspace
CMake	3.19+	C++ build configuration
vcpkg	2025.08.27	C++ dependency manager
JDK	17	Java runtime for Tika document parser
Maven	3.9.6	Java build tool for Tika integration
Apache Tika	3.2.3	Document parsing (PDF, DOCX, XLSX, etc.)
Python packages	per node	Each node's requirements.txt is installed automatically

Platform Support

Platform	Architecture	Status
macOS	Intel (x86_64)	Supported
macOS	Apple Silicon (arm64)	Supported
Linux	x86_64	Supported

Platform-Specific Requirements

macOS:

• Xcode Command Line Tools (xcode-select --install)

Linux:

• GCC 9+ or Clang 10+ (for C++17)
• Standard build tools (build-essential on Debian/Ubuntu)

Windows:

Verifying Your Environment

After installing Node.js, confirm it is available:

node --version    # Should print v18.x.x or higher

Then build. The builder will report any missing platform prerequisites during the build process:

./builder build
