Building a Rapid A/B Test Generator with Google Stitch SDK

In the fast-paced world of UI/UX design, the ability to quickly visualize and iterate on ideas is a superpower. Today, I'm excited to share a deep dive into Stitch A/B Tester , a CLI tool I built that turns a single text prompt into a full-blown A/B testing dashboard in seconds. The Problem: The Prototyping Bottleneck Usually, creating A/B test variants involves: Designing a base screen in Figma. Manually duplicating and tweaking layouts, colors, and assets. Exporting images or setting up a prototype link. This process can take hours, if not days. I wanted to see if we could compress this into seconds . The Solution: Google Stitch SDK The Google Stitch SDK is a powerful tool for programmatically generating and manipulating UI designs. By leveraging its generate and variants capabilities, we can automate the entire creative workflow. Technical Architecture The app is built as a Node.js CLI using: Google Stitch SDK : For UI generation. Vercel AI SDK : For autonomous tool orchestration. T
