Isn't it stealing from Aceternity UI and other UI libraries without their permission using their component library ? Just curious to ask.

@ishwar_thecoder Great question! We always credit the original authors and provide links to their official websites. Moreover, many of these creators share their referral links with us to promote their pro components. This way, we ensure they benefit directly from any traffic or purchases driven by our platform. Everyone wins!

Hey how is different from directly using shadcn, magicui ,aceternity UI etc ??

@jalajdu Great question! 21st.dev isn’t a library itself—it’s a marketplace for component libraries, individual components, and design engineers to share their work. Instead of being tied to one style or framework, it allows developers to discover, use, and even contribute high-quality components from various creators.

@jalajdu basically because design engineers can publish their own components, we have the largest lib of unique components that can't be found elsewhere

The API's responsiveness is impressive—getting polished components with minimal latency enhances productivity. Pairing it with tools like Apidog has further optimized my development process.

looks promising! any plans to support other frameworks?
Serafim

@artyshatilov Thanks, Arty! Supporting other frameworks is definitely something we’re considering for the future. For now, we’re focusing on perfecting the experience for Tailwind and React users. Are there any frameworks in particular you’d like to see supported?
