Alloy vs. Proto.io

Alloy is an AI prototyping tool for product managers. Clone your existing product or website with the Chrome extension to turn ideas, wireframes, and Figma designs into interactive, high-fidelity prototypes your team and customers understand. Alloy's Cloud Agent connects to your codebase and takes changes from prototype to production, and its AI chat can redesign any existing website. Design to code, no engineers required.

Proto.io is an industry-leading prototyping platform. It gives designers, entrepreneurs, developers, and anyone with a great idea the power to create fully-interactive web and mobile prototypes of any fidelity that look and work exactly like a real app — all without a single line of code. It seamlessly covers the entire design process from early wireframes and mockups to interactive, animated, high-fidelity prototypes. Users can build, animate, review, and test their prototypes, all in one place, making the whole process easier than ever.
