Rebuild any app you pay for, the legal way

What it is

Replica is a free, open-source pack of eleven Claude skills (6,000+ stars on GitHub). It rebuilds an app's features and flows "clean-room style": it never copies the original's source code, assets, logos, trademarks, text or private APIs.

The eleven skills, in order

1. Recon: maps every screen, flow and feature.
2. Architect: plans the stack, database and API.
3. Design: turns screenshots into your own design system.
4. Build: builds the app screen by screen.
5. Backend: adds logins, database, payments and integrations.
6. Test: writes test plans and checks every flow for bugs.
7. Diff: scores how close your version is.
8. Entrepreneur: mines real reviews for what users hate and turns it into a fix plan.
9. Brand: new name, palette and logo brief, and a sweep for leftover original branding.
10. Launch: landing page, pricing and store listing.
11. Deploy: final checks and putting it live on your domain.

Your first run

Use Replica on [app name and website]. Start with recon using only public pages and my own account.
Show me the screen map before you build anything.

Good to know

• Use only what you're allowed to see: public pages and your own account.
• Read the Backend and Deploy skills before running them. They touch payments and DNS.
• A rebuilt app can still run into patents or terms of service. If you plan to charge money, talk to a lawyer first. This guide isn't legal advice.

You need the Claude desktop app with Claude Code (any paid plan, Pro is enough). For setup we recommend Opus 5.5.
