GitHub Explorer
GitHub's free API + AI

Explore any repo, read the code, ship the docs.

Paste a GitHub repository or a username. Browse every file and folder, read the source with syntax highlighting, and let AI draft the README, documentation or next steps.

/

Try facebook/react for a repository, or torvalds for a user's repos.

What you can do

Everything reads through GitHub's public API straight into your browser.

01

Browse & read

Open a repository, walk its full file tree, filter by name, and read any source file with syntax highlighting, line wrapping and a one-click copy or download.

02

Explore a user

Enter a username to list every public repository they own, sorted by most recently updated, each with language, stars and description.

03

Let AI draft

Generate a README, write developer documentation, get a prioritised roadmap of what to build next, or ask questions about the codebase.

Frequently asked questions

How does GitHub Explorer work?
It reads public repositories through GitHub's free REST API: repository metadata, the full file tree, and raw file contents. Everything is loaded straight into your browser, and no account is needed for public repositories.
Why do I sometimes hit a rate limit?
GitHub's unauthenticated API allows 60 requests per hour per IP address, which a few repository opens can use up. Add an optional personal access token in settings to raise the limit to 5,000 requests per hour; the token is stored only in your browser.
Which repositories can I open?
Any repository that is public. Private repositories are only visible with a personal access token that has access to them, and the token never leaves your browser except when calling GitHub's own API.
How does the AI feature work?
Choose a task such as generating a README, writing documentation, suggesting what to build next, or explaining a file. The page sends a small summary of the repository, its file tree and a few key files to the site's server, which passes it to an AI model and returns the result.
Is the AI output ready to use?
Treat it as a strong first draft. The model sees the file tree and a handful of key files, not your whole codebase, so review anything it claims about behaviour, versions or commands before committing it.
Do you store the repositories I open?
No. Browsing happens directly between your browser and GitHub. The recent-repositories list and any personal token are stored in your own browser storage, never on our servers.

This is an independent viewer for GitHub's public data and is not affiliated with GitHub. It never writes to your repositories.

Settings

A personal access token raises GitHub's limit from 60 to 5,000 requests per hour and lets you open private repositories. It is kept in this browser only and is sent only to GitHub.
