How to Set Up Lum1104/Understand-Anything Locally: Complete Installation Guide

To set up Lum1104/Understand-Anything locally, clone the repository, install dependencies using pnpm, build the core TypeScript package and React dashboard, and launch the development server to visualize interactive knowledge graphs.

Understand-Anything is a multi-agent, tree-sitter and LLM hybrid tool that transforms codebases into interactive knowledge graphs. Whether you are analyzing a new project or integrating the tool into your development workflow, this guide walks you through the exact steps to configure and run Lum1104/Understand-Anything on your local machine using the official monorepo structure.

Prerequisites

Before you begin, ensure your environment meets the following requirements:

• Node.js ≥ 22 (tested on v24) – Required by the TypeScript build scripts.
• pnpm ≥ 10 – The monorepo workspace manager, pinned in the root package.json.
• git – To clone the repository.
• git-lfs (optional) – Recommended for tracking large knowledge-graph JSON files exceeding 10 MB.

Clone the Repository

Start by cloning the repository and navigating into the project directory:

git clone https://github.com/Lum1104/Understand-Anything.git
cd Understand-Anything

The repository is organized as a pnpm workspace, with all packages located under the understand-anything-plugin/ directory.

Install Dependencies

Run the following command to install all workspace dependencies:

pnpm install

This command reads the workspace manifest (pnpm-workspace.yaml) and installs:

• Core dependencies – Tree-sitter parsers and web-tree-sitter as defined in understand-anything-plugin/packages/core/package.json.
• Dashboard dependencies – React, Zustand, and Tailwind v4 as defined in understand-anything-plugin/packages/dashboard/package.json.

Build the Core Package

Compile the core TypeScript library using the workspace filter command:

pnpm --filter @understand-anything/core build

This executes the TypeScript compiler (tsc) and outputs the compiled files to the dist/ directory. The export map in the core package.json ensures the dashboard only imports browser-safe sub-paths (./search, ./types, ./schema).

Build the Dashboard Package

Build the React-based visualization interface:

pnpm --filter @understand-anything/dashboard build

The dashboard build process generates a static bundle in dist/, ready for deployment or local development.

Run Tests (Optional)

Verify the installation by running the test suite:

• Core tests only:

  pnpm --filter @understand-anything/core test

• Full test suite (including skill plugins):

  pnpm test

Tests utilize Vitest and cover the core engine and skill definitions. Example fixtures are located in tests/skill/understand/, including files like scan-result-large-community.json.

Start the Development Server

Launch the hot-reload development server to access the dashboard:

pnpm dev:dashboard

The server typically starts at http://localhost:3000 (check console output for the exact port). The dashboard reads the generated knowledge graph from .understand-anything/knowledge-graph.json via the /file-content.json endpoint.

Run the Analyzer

To analyze a target project and generate the knowledge graph, run the CLI from the repository root:

node ./understand-anything-plugin/dist/cli.js understand

The analyzer creates .understand-anything/knowledge-graph.json in your target directory. Subsequent runs are incremental, scanning only files that have changed since the last execution.

One-Line Installer (Optional)

For a platform-native CLI experience similar to Claude Code or other integrations, use the automated installer:

macOS / Linux:

curl -fsSL https://raw.githubusercontent.com/Lum1104/Understand-Anything/main/install.sh | bash

Windows PowerShell:

iwr -useb https://raw.githubusercontent.com/Lum1104/Understand-Anything/main/install.sh | iex

The installer script (install.sh or install.ps1) clones the repository to ~/.understand-anything/repo and creates the necessary symlinks for your specific platform.

Summary

Setting up Lum1104/Understand-Anything locally involves several key steps:

• Install Node.js ≥ 22 and pnpm ≥ 10 before starting.
• Build both the core (@understand-anything/core) and dashboard (@understand-anything/dashboard) packages using pnpm --filter.
• Use pnpm dev:dashboard to start the development server at localhost:3000.
• Generate knowledge graphs using the CLI entry point or the one-line installer.
• Store generated graphs in .understand-anything/knowledge-graph.json, optionally tracked with git-lfs for large files.

Frequently Asked Questions

What are the minimum system requirements to run Understand-Anything locally?

You need Node.js version 22 or higher and pnpm version 10 or higher. The TypeScript compiler and React dashboard build processes rely on modern Node features, while pnpm manages the monorepo workspace dependencies defined across understand-anything-plugin/packages/core/package.json and understand-anything-plugin/packages/dashboard/package.json.

How do I update the knowledge graph after modifying my code?

Simply re-run the analyzer command. The system performs incremental updates, scanning only changed files to regenerate .understand-anything/knowledge-graph.json. For automatic updates on every commit, enable the post-commit hook using /understand --auto-update after installing the CLI via install.sh.

Can I use npm or yarn instead of pnpm?

No, the repository is configured specifically as a pnpm workspace using pnpm-workspace.yaml. The dependency hoisting and workspace linking are optimized for pnpm, and the build scripts in the root package.json assume pnpm's filtering syntax (--filter).

Where is the generated knowledge graph stored?

By default, the analyzer outputs to .understand-anything/knowledge-graph.json. The dashboard reads from this location via the /file-content.json endpoint. For graphs larger than 10 MB, the documentation recommends using git-lfs to track this file while excluding intermediate/ directories and diff-overlay.json from version control.
