Blade is the open-source design system powering Razorpay, India's payments platform, with over 40 components and full token coverage shared across React Web and React Native for dashboards, websites, and mobile apps.
One shared component package genuinely spans desktop web, mobile web, and native mobile app at once, so a fintech team building across all three surfaces doesn't need three separate component libraries drifting out of sync.
Developers building fintech or payments products across web and React Native who want a single, actively maintained component source for both.
Both the code and the Figma library are open source, actively published (updated roughly monthly per its version history), worth checking npm directly for the current release before adopting.
Razorpay's own toolkit for building cohesive experiences across its platform.
