Alloy vs. Penpot

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.

Penpot is the open-source design platform for teams that build digital products at scale. Available in the browser or self-hosted, Penpot helps product teams connect design, code, and AI workflows in one open, interoperable platform. Built on web standards such as SVG, CSS, HTML, and JSON, Penpot gives teams more control over their design infrastructure, avoids vendor lock-in, and makes design work easier to integrate with development workflows. Penpot is built for teams working across complex products, design systems, and cross-functional workflows.
