Builder.io - Cheatsheet
Overview
Quick reference: Builder.io in 2025 blends visual editing with AI-first design-to-code generation and component-level automation.
AI Features
Core Capabilities
- Generate responsive components from design prompts and screenshots
- Design-to-code with export options (React, Vue, HTML/CSS)
- Auto accessibility improvements and ARIA annotations
- Component versioning, testing, and visual diffs
Practical Patterns
- Use a prompt that includes target framework + constraints (e.g., "responsive React card, no external deps").
- Provide a screenshot + a short spec for better fidelity.
- Iterate with the visual diff view and lock design tokens to prevent regressions.
Example: Prompt for a responsive card
Prompt:
"Create a responsive product card in React. Include product image, name, price, and a Buy button. Use CSS modules, mobile-first layout, and ARIA labels for accessibility."Integration Tips
- Keep tokens small by sending component JSON instead of full page HTML when possible.
- Automate visual tests: cache snapshots and fail builds on visual regressions.
- Reuse component libraries as the grounding context so the AI outputs match your codebase style.
