What should you check before importing a 21st.dev component?
Start from the one piece your page needs, such as a header or form. Compare the preview with your actual content. The useful handoff is a component you can inspect, replace and style in your project.
- Read the individual component’s installation instructions and check what dependencies or files it adds.
- Test a small route before replacing a shared layout. Inspect the keyboard behavior and the mobile width you need.
Choose a resource for a real screen
Components, themes and templates serve different jobs. A component suits one interaction; a template offers a broader starting structure. Match the resource to the product screen before adding visual effects.
Bring the source into your existing app
The documented workflow connects resource discovery with source and prompts for an AI agent. Check framework requirements and dependencies, then adapt colors, spacing and content to the app already being built.
Review the result and the asset terms
A polished preview is a starting point. Check narrow screens, keyboard use and empty states in the destination app. Read the selected asset's source and terms; community resources should not be assumed to share one license.
A few more details
Is 21st.dev a complete application backend?
A UI resource does not establish your product's data model, permissions or payment behavior. Evaluate those separately from the interface resource you select.
Why do older tutorials mention Magic?
21st's official changelog records the evolution from Magic to 21st AI. Use current documentation for names and setup instead of assuming an older tutorial still matches the product.
