What is 21st.dev?
21st.dev is a professional marketplace and AI toolkit designed for developers and design engineers who need to build beautiful, functional user interfaces with greater speed and precision. It solves a common frustration: finding a UI component that's almost perfect but requires significant rework. 21st.dev transforms this bottleneck into a creative advantage by using AI to instantly generate multiple, high-quality variants of any component you need, allowing you to start with a choice, not a compromise.
Key Features
🤖 Instant UI Variant Generation Instead of a single, rigid output, our AI generates several distinct, shippable versions of the component you request. Describe a "dashboard layout" or "pricing section," and immediately receive clean, well-crafted options. This eliminates the "blank page" problem and allows you to choose the best foundation for your project.
🔌 Seamless IDE Integration Bring the full power of 21st.dev directly into your editor with our universal IDE extension (for VS Code, Cursor, and more). Select an element, write a prompt, and let the AI instantly edit, create, or fix it without context switching. It intelligently sends the necessary code and context to your AI agent for precise results.
🧑💻 Community-Sourced AI Quality Our AI doesn't work in a vacuum. Every component it generates is inspired by the best practices and real-world examples shared by top design engineers in the 21st.dev community. This ensures the output is not just syntactically correct, but also modern, polished, and practical.
✏️ AI-Assisted Remixing and Editing Go beyond initial generation with powerful fine-tuning capabilities. Use the "Remix with AI" feature on any community component or use inline chat to make micro-edits—from adjusting specific CSS styles to refactoring layouts—giving you precise control to perfect the final code.
Why Choose 21st.dev?
A Workflow That Mirrors Real Design Engineering Great design is iterative. We built 21st.dev around this principle. Our variant-based approach provides strong options from the start, enabling you to iterate quickly rather than trying to craft the "perfect" prompt. It's a workflow that respects and enhances your professional judgment.
An Ecosystem That Rewards Craftsmanship Our AI model is a direct reflection of our community's talent. We believe in recognizing and rewarding the creators who make this possible. By sharing revenue with the authors whose components inspire AI generations, we foster a sustainable ecosystem built on quality, respect, and shared success.
Conclusion:
21st.dev bridges the critical gap between the raw speed of AI generation and the nuanced control of hands-on craftsmanship. It provides the tools to build, refine, and ship exceptional UI at a pace that was previously unattainable, all while ensuring the output meets a high standard of quality.
