RepoVerse is a free tool that turns any public GitHub repository into an explorable 3D city in the browser. Folders become districts, files become buildings sized by how much code they hold, and the dependencies between them become the roads running from one to another. It runs on Three.js and needs no install and no signup for public repositories.

How does RepoVerse build a city from a repository?

It clones the repository, parses every source file into an abstract syntax tree, and reads the import statements to find what depends on what. That graph is laid out as a city: a folder becomes a district, a file becomes a building whose height is its line count, and each resolved import becomes a road. Git history is read in parallel, so how often a file changes and how recently are visible in the skyline rather than buried in a log.

Yes. Scanning public repositories, exploring the 3D city, sharing a link to one and the written summary every city carries are all free and need no account. A paid plan adds private repositories and the security review, which checks every declared dependency against the OSV vulnerability database and reads the repository's own source for hard-coded credentials, injectable queries and disabled certificate checks.

Which languages does RepoVerse support?

Python, JavaScript, TypeScript and TSX are parsed for functions, classes and imports. Go, Rust, Java, Kotlin, C#, PHP, Ruby, C++ and Swift are mapped as files and districts. RepoVerse can also scan a public website instead of a repository, returning its pages, scripts, stylesheets and the technologies it detects.

Does RepoVerse need access to my private code?

Not for public repositories — those are read anonymously and nothing is stored beyond the generated city. Private repositories need you to sign in with GitHub and grant access, and that token is used only to fetch the repository you asked for. The repository itself is never sent to a third party.

What is the metropolis?

The metropolis is a single 3D world holding every repository anyone has scanned. Each one owns the land around it, projects that share dependencies meet at a border, and the dependencies between them are roads with traffic moving along them. You can fly over it and walk into any city you find.

Can I set frame-ancestors in a meta tag?

No. Browsers ignore frame-ancestors in a CSP, so it has to be an HTTP header.

What if my page is meant to be embedded?

List the sites allowed to embed it in frame-ancestors instead of leaving framing open to everyone.

Clickjacking: stolen clicks through an invisible frame

If any site can put your page in a frame, it can make the frame invisible and line a button of yours up under something the visitor wants to click.

Example

Frameable

HTTP/1.1 200 OK
Content-Type: text/html
(no X-Frame-Options, no CSP frame-ancestors)

Protected

Content-Security-Policy: frame-ancestors 'self'
X-Frame-Options: DENY

How it happens

The attacker's page loads yours in a transparent iframe, positioned so that "Delete account", "Confirm payment" or "Allow camera" sits under a harmless-looking button. The visitor is logged in to your site, so the click is real. Any page that changes state with a single click is a target.

How to fix it

Tell the browser who may frame you.

Content-Security-Policy: frame-ancestors 'self' (or 'none')
X-Frame-Options: DENY or SAMEORIGIN for older browsers
Send them as headers on every HTML response
Ask for confirmation on destructive actions as a second line

How RepoVerse finds it

ModeratePages can be framed by any site
Another site can load your pages in an invisible frame and trick a logged-in visitor into clicking buttons they cannot see — changing settings, confirming payments.

Questions

Can I set frame-ancestors in a meta tag?: No. Browsers ignore frame-ancestors in a <meta> CSP, so it has to be an HTTP header.
