Builder.io

Ingests Figma designs via copy/paste or native plugin, extracts design tokens (colors, typography, spacing), component definitions, and layout hierarchy, then generates production-ready React/Vue/Angular/Svelte component code that respects the user's existing design system. The system maps Figma layers to component props and CSS-in-JS or scoped styling based on the target framework, enabling one-click conversion of visual designs into framework-specific code without manual translation.

Accepts freeform text prompts describing desired UI components, optionally augmented with 'backend context' (API schemas, database models, business logic descriptions) provided by the user. The AI agent generates framework-specific component code that integrates with the described backend, leveraging connected repository code standards and existing components to ensure consistency. This enables developers to describe components in business terms rather than technical specifications.

Tracks user actions (code generation, visual edits, publishing, user invitations) in an activity log with 30-day retention on Team tier+. The system provides visibility into who made changes, when, and what was changed, enabling teams to audit modifications and understand project history. Free/Pro tiers have unknown activity history retention (likely no retention or very limited).

Provides a VS Code extension (available on Free tier+) that enables developers to generate components directly from the editor without switching to Builder.io workspace. The extension allows triggering generation from code comments, viewing previews inline, and pushing generated code to the current project. This integrates Builder.io's code generation capabilities into the developer's primary IDE.

Provides 'Privacy mode' (Enterprise tier) and 'AI training opt-out' (Team tier+) to address data privacy concerns. Privacy mode (technical details unknown) likely prevents design and code data from being used for model training or analytics. AI training opt-out on Team tier allows opting out of model training while still using the platform. Enterprise tier enables Privacy mode by default with opt-in for training.

Enables sharing generated component previews via password-protected links (Team tier+) or public links (Free tier+). Users can control visibility (public by default on Free tier, password-protected on Team tier) to share work with stakeholders without granting full workspace access. This enables design review and feedback workflows without exposing the full Builder.io workspace.

Provides a usage metrics dashboard (Team tier+) showing generation activity, credit consumption, user activity, and other analytics. The dashboard enables teams to monitor how Builder.io is being used, track credit consumption, and identify usage patterns. This supports capacity planning and cost optimization.

Provides a browser-based visual IDE ('Fusion') where generated or existing components can be edited via drag-and-drop, property panels, and inline styling controls. Changes made visually are reflected in the underlying code, and the editor maintains bidirectional sync with the code representation, allowing developers to switch between visual and code editing modes. The editor supports 'full precision control' over element styling and component props.

Connects to user's Git repository (GitHub, GitLab, Bitbucket, Azure DevOps, or self-hosted) to access existing code, component libraries, design tokens, and coding standards. During code generation, the AI agent analyzes the repository context to ensure generated components reuse existing components, match coding style, and respect design system constraints. This enables generated code to feel native to the codebase rather than generic or out-of-place.

Generates production-ready component code in React, Vue, Angular, or Svelte from a single design or prompt, with framework-specific optimizations and idioms. The system adapts output to each framework's conventions: React uses JSX and hooks, Vue uses single-file components with scoped styles, Angular uses decorators and services, Svelte uses reactive declarations. Users select target framework(s) and receive framework-native code rather than generic or transpiled output.

Implements a token-bucket style usage model where each code generation action consumes 'Agent Credits' from a daily and monthly quota. Free tier provides 25 credits/day (75/month), Pro tier offers 500/month with pay-as-you-go overages at $25 per 500 credits, and Team/Enterprise tiers provide unlimited credits. The system tracks credit consumption per user and enforces hard limits, preventing generation when quota is exhausted.

Integrates Builder.io Agent with Slack and Jira (Team tier+) to enable code generation workflows initiated from chat or issue tracking. Users can trigger component generation from Slack threads or Jira tickets, with Builder.io Agent responding with generated code, previews, and status updates. This enables design-to-code workflows without leaving existing team communication and project management tools.

Supports MCP Servers (Model Context Protocol) to inject custom context into code generation. Built-in MCP servers are available on Pro tier+, and custom MCP servers can be created and deployed on Team tier+. This enables organizations to provide domain-specific knowledge, custom design systems, backend schemas, or proprietary code patterns to the AI agent during generation, extending the agent's context beyond what Builder.io provides natively.

Provides a 'Publish' product (separate from Fusion code generation) that functions as a headless CMS for managing and publishing on-brand content. Generated or manually created components can be published via API, enabling content teams to manage content independently of code deployments. The system supports API-based content delivery, allowing frontend applications to fetch published content and render it using generated components.

Implements role-based access control with predefined roles (Admin, Developer, Designer, Editor) available on Team tier+. Each role has specific permissions for code generation, visual editing, content publishing, and workspace management. The system supports up to 5 users on Free/Pro tiers, 20 users on Team tier, and custom user counts on Enterprise tier, enabling multi-user collaboration with granular permission control.
