Turn webpages into editable frontend projects.
Web Clone Lab is a developer-focused Chrome extension for capturing and reconstructing the frontend of webpages into an organized local project.
See something interesting on the web?
Capture it. Inspect it. Learn from it. Remix it.
- Capture the current webpage's DOM structure
- Collect linked CSS resources
- Collect JavaScript resources
- Detect images and other frontend assets
- Detect inline CSS and inline JavaScript
- Discover additional resources referenced by CSS and JavaScript
- Build a local resource graph
- Reconstruct resources into an organized project structure
- Rewrite resource paths for local use
- Generate a clone manifest containing capture and resource information
- Export the reconstructed frontend project as a ZIP file
- Designed to operate locally without a dedicated application backend
Web Clone Lab treats a webpage as a collection of interconnected frontend resources.

The goal is not to reproduce a website's server-side application.
Instead, Web Clone Lab focuses on reconstructing the frontend layer that can be observed and captured from the browser.
A reconstructed project is organized into a normal local frontend structure.
A typical output may look like:
web-clone/ βββ index.html βββ css/ β βββ ... β βββ inline-1.css βββ js/ β βββ ... β βββ inline-1.js βββ assets/ β βββ images/ β βββ fonts/ β βββ ... βββ clone-manifest.json
Resource URLs are mapped to local paths so that the generated project can be inspected and modified as a standalone frontend project.
Web Clone Lab isn't just about copying webpages.
It's a playground for exploring how modern webpages are constructed, experimenting with frontend code, and turning existing ideas into new ones.
Capture a page.
Look inside it.
Find something interesting.
Change it.
Break it.
Fix it.
Build something new.
Capture β Inspect β Remix β Create
And then there is the completely unnecessary part.
Random Remix.
Drop one or more frontend website ZIPs into the laboratory and let the Remix Engine randomly combine their frontend structures, styles, scripts, components, and assets.
Use your own projects.
Use exported projects.
Mix multiple sources.
Then press:
ββββββββββββββββββββββββ β RANDOM REMIX β ββββββββββββββββββββββββ
You might get something brilliant.
You might get something terrible.
You might get something that somehow runs.
Nobody knows.
The final result is exported as a new ZIP project.
Open it.
Modify it.
Break it.
Fix it.
Break it again.

The project intentionally keeps the architecture modular so that the capture, analysis, reconstruction, and remix systems can evolve independently.
Web Clone Lab is a frontend reconstruction tool, not a complete website server cloning system.
It does not attempt to automatically reproduce:
- Server-side application logic
- Databases
- Private APIs
- Authentication systems
- Server-side rendering infrastructure
- WebSocket backends
- Application-specific backend state
- Other server-side functionality that cannot be captured from the frontend
Modern websites can also contain dynamic behavior, protected resources, framework runtimes, external services, and other mechanisms that cannot always be reconstructed perfectly.
Therefore, the output should be considered a frontend snapshot/reconstruction, not a guaranteed byte-for-byte reproduction of the original website.
Web Clone Lab is intentionally experimental.
Some websites will reconstruct surprisingly well.
Some will partially work.
Some will break spectacularly.
That's part of the laboratory.
The project is designed to make experimentation with real-world frontend structures easier and faster.
Only capture, reuse, modify, or redistribute webpage code and assets when you have the appropriate rights or permission to do so.
This project is intended for:
- Learning
- Frontend experimentation
- Development
- Prototyping
- Authorized testing
- Personal projects
- Remixing your own work
Do not use Web Clone Lab to copy, impersonate, or redistribute websites or assets without appropriate authorization.
See the project's license file for licensing information.
Capture it.
Understand it.
Remix it.
Then make it yours.
