Cotyper

Cotyper is an AI web app builder that turns a plain-English description into a working prototype and a real codebase. It’s designed for developers and advanced “vibe coders” who want to validate ideas quickly and end up with an actual project—not just mockups.

Real code generation

Unlike typical no-code tools, Cotyper produces a full codebase you can:

• Run locally
• Deploy to a server
• Download and modify

This makes it useful for rapid MVPs as well as as a starting point for production products.

Built on Claude Code

Cotyper is powered by Anthropic Claude Code, which helps the AI understand application structure, architecture, and dependencies. You describe the app’s UI and logic in simple text, and the system assembles both the prototype and the underlying code—reducing hours of manual setup.

Who it’s for

Cotyper is a fit for:

• Developers
• Startups
• Product managers
• Technical founders

It helps shorten the path from idea to a working web app while keeping full control over the code.
