GitHub Project Tree Generator

Working with open-source or collaborative codebases often means diving into a sea of folders and files. But wouldn't it be great if you could instantly understand the GitHub repository structure of any project, without cloning it or digging through dozens of directories?

Introducing the GitHub Project Tree Generator — a developer tool that allows you to generate and preview the entire structure of a Git repository in just one click. Whether you want a text-based folder layout or a diagrammatic view using Mermaid.js, this tool saves you hours of manual work.

What Is the GitHub Project Tree Generator?

The GitHub Project Tree Generator is a web-based utility inside ReadmeCodeGen that fetches the entire file and folder layout of any public GitHub repository, and instantly converts it into a clean, copy-ready format. You can choose between:

• ASCII tree style — perfect for adding to README.md files
• Mermaid Diagram — ideal for visual architecture in docs or wikis

It works entirely in-browser. You don't need to clone the repo or run Git commands. Just paste the GitHub repo URL and click one button — that's it.

Why Developers Need This Tool

A well-documented file structure makes a project easier to understand, contribute to, and maintain. Especially in open-source communities or team projects, having a clearly displayed GitHub repository tree structure is a huge productivity boost.

Instead of manually writing or drawing the tree structure, this tool automates the process. It's ideal for:

• README documentation
• Internal architecture diagrams
• Code reviews and onboarding
• Open-source project organization

How It Works

1. Paste any GitHub repo URL (e.g., https://github.com/vercel/next.js)
2. Click "Import Repository" to fetch repo data
3. Select your preferred output style: Text or Mermaid
4. Click "Generate File Tree" to auto-generate the layout
5. Preview the result and copy the Markdown

Everything is rendered client-side, and your repo data is never stored. The tool is optimized for public repositories, but you can also use a GitHub token for private ones.

Key Features

• Auto-import from GitHub — fetch file paths using GitHub API
• AI-powered structure generation — converts raw data into tree format
• Supports both formats — Text and Mermaid
• Live preview — see what your file tree will look like
• Markdown-ready — copy and paste into README or docs
• Error handling — smart detection for invalid URLs, rate limits, private repos

Output Formats Explained

1. Text Tree Format

Generates a clean indented tree that looks like this:

src
├── components
│   ├── Header.tsx
│   └── Footer.tsx
├── App.tsx
├── README.md
└── package.json

Perfect for README files and documentation on GitHub.

2. Mermaid Diagram Format

Converts your folder structure into a mermaid code block for rendering flowcharts:

Ideal for use in documentation websites like Docusaurus, GitBook, or Notion.

How to Use It

1. Go to the GitHub Project Tree Generator tool inside ReadmeCodeGen
2. Enter a valid GitHub repository URL
3. Click "Import Repository"
4. Select "Text Tree" or "Mermaid Diagram"
5. Click "Generate File Tree"
6. Copy the Markdown code or use the live preview

You can now paste this into your README, GitHub Wiki, or internal docs.

Benefits

• No setup or cloning required
• Save hours compared to manual formatting
