If you want to gauge the consistency of your design components across projects and teams, Stylebit is a great option. It's a full-featured design system management platform that tracks component usage and adoption rates, as well as misuse. Stylebit can spot variable adoption and usage so you can track and optimize consistency of your design components. It supports React, React Native and Web Components, and offers free and enterprise pricing tiers so you can pick the best fit.
Another contender is Relume, an AI-powered tool that helps you build websites by creating sitemaps, wireframes and UI styleguides. Relume comes with a big library of prebuilt components and integrates with Figma and Webflow. That can help ensure consistency across projects and teams by offering a single set of design elements.
If you're in the UX writing camp, the UX Writing Assistant is a useful Figma plugin that suggests copy with AI technology and that integrates with design systems to keep your UX content consistent. That can help you cut down on design reviews and otherwise speed up your design work.
Last, Mockitt is an all-in-one design, prototyping and collaboration tool with AI tools for generating components and real-time collaboration. That means you can design and prototype more consistently across teams.
