What it does
Replica is a set of eleven "skills" (instruction packs) for Claude, Anthropic's AI assistant. Together they walk you through rebuilding the features of an existing app as your own product. One skill studies the app from public pages, screenshots, store listings and your own account. Others plan the technology, rebuild the look, build the screens, and add sign-in and payments.
Later skills test the new app for bugs, score how close it is to the original, and read real user reviews to find common complaints worth fixing. Further skills give your version a new name and brand, write a landing page and app store listing, and help put it live on your own website address.
Its makers say it copies what an app does, not what it owns: no source code, logos, wording or content. The skills check your code for leftover traces of the original before launch. The README notes this is not legal advice and suggests checking trademarks and talking to a lawyer before selling.
Who it's for
People using Claude or Claude Code who want to build their own version of an existing app's features and turn it into a product.
Can I use it without coding?
With some setup. You install it by pasting a link into Claude or running a few commands in Claude Code, and the helper tools need Python. New to this? Start here.
Can I run it?
- Cost

- Computer
- An ordinary computer is fine
- API key
- Not needed
Try it
- Paste the project's GitHub link into Claude and ask it to install the skill, or add it as a plugin in Claude Code.
