About GitTree
Free, open-source tool to instantly explore GitHub repository structures
What is GitTree?
GitTree is a free, open-source web application that transforms any public GitHub repository into a rich, interactive visualization. In seconds, you can explore the complete directory tree, navigate folders, inspect file distributions, and access key repository metrics — all directly from your browser, without installing anything or cloning a single line of code.
Whether you are evaluating a new dependency, onboarding to an unfamiliar codebase, conducting a code review, or documenting a project's structure, GitTree gives you an instant, structured view that would otherwise require local setup and manual inspection.
Interactive Tree Visualization
Navigate the full repository directory tree with expandable nodes, real-time search filtering, and one-click clipboard copy in ASCII or Markdown format.
Repository Metrics & Analytics
Access file count, total repository size, language distribution charts, star and fork counts, and contributor statistics — all sourced live from the GitHub REST API v3.
Zero Setup — Instant Analysis
Paste any public GitHub URL or shorthand (e.g., user/repo) and get results in seconds. No account, no installation, no API key required.
Flexible Export Options
Export the full repository structure as JSON for programmatic use, CSV for spreadsheet analysis, or plain text/Markdown for README documentation and reports.
History
GitTree was born out of a recurring developer frustration: understanding the structure of an unfamiliar GitHub repository typically meant cloning it locally, navigating the file system, and mentally mapping folders — a slow, context-switching process that interrupted workflow and wasted time.
The initial prototype, built in early 2025 by João Claudiano, focused on a single goal: render any public repository tree in a browser in under three seconds. Over subsequent iterations, the tool evolved to include metrics dashboards, multi-format export, a smart local cache, dark and light themes, multi-language support, and an accessible, mobile-friendly interface.
What started as a personal productivity tool has grown into a free, open-source project used by developers, technical writers, code reviewers, and learners worldwide. GitTree is hosted on Cloudflare Pages, operates entirely client-side, and makes no use of external databases or server-side processing.

GitTree is engineered as a fully client-side application — there is no backend server, no database, and no server-side code execution. All processing happens in the user's browser, ensuring privacy, fast load times, and zero infrastructure overhead. The core stack:
Open Source
GitTree is fully open-source under a permissive license. The complete source code is available on GitHub for anyone to inspect, fork, and contribute to. We actively welcome pull requests, bug reports, feature suggestions, and documentation improvements from the community.
Open-source transparency is a core principle of GitTree: you can audit exactly how your repository URLs are processed, verify that no data is stored server-side, and extend the tool to suit your workflow.
