Bolt.new is an AI-powered full-stack web development platform by StackBlitz that enables users to build, run, edit, and deploy complete web applications directly in the browser using natural language prompts. It addresses the barrier to entry in web development by combining an AI coding assistant with an in-browser development environment powered by WebContainers technology, eliminating the need for local setup, package installation, or server configuration. Users can go from a text description to a fully functional deployed application in minutes without leaving their browser.

Bolt.new differentiates itself by running a complete Node.js environment inside the browser using WebContainers, meaning it can install npm packages, execute server-side code, run build tools, and manage databases all within a single browser tab. It supports major frameworks including Next.js, Astro, Remix, Vite, and more, and provides a full-featured code editor alongside the AI chat interface. The platform includes integrated deployment to Netlify, real-time preview of changes, version history for reverting edits, and the ability to attach images or design files as context for the AI to reference during generation.

Bolt.new targets developers, entrepreneurs, designers, and product managers who want to rapidly prototype or build production web applications without the overhead of traditional development environments. It is particularly popular for creating MVPs, landing pages, internal tools, and side projects where speed matters more than granular control. The platform integrates with GitHub for code export, supports Supabase for backend database needs, and provides shareable project links for collaboration and review.

Uizard logo

Uizard

Editable UI flows from prompts, screenshots and sketches

AI-assisted product-design platform that turns prompts, screenshots and hand-drawn sketches into editable UI flows for non-designers and early product ideation, complementing rather than duplicating developer-first code generators.

Magic Patterns

Design-system-aware AI prototyping for code-ready product interfaces

Magic Patterns turns product ideas, prompts, screenshots, and existing UI into editable, code-ready interfaces. Its design-system-aware editor supports collaborative iteration, two-way GitHub sync, and an MCP workflow for moving designs between the canvas and coding agents—positioning it between prompt-to-app builders and design-handoff tools rather than as a single-screen generator.

Mitosis

Write components once and compile them into native code for multiple frameworks

Mitosis is Builder.io-backed open-source infrastructure for writing a component once and compiling it into native framework components for React, Vue, Angular, Svelte, Qwik, Solid, React Native, and other targets. It supports cross-framework design systems and Figma-to-code synchronization, but is distinct from the Builder.io visual builder product.

Figma Console MCP

Turn a Figma design system into a programmable API for AI assistants

Figma Console MCP is open-source design-system infrastructure that exposes Figma to AI assistants through MCP. It supports structured extraction, design creation and editing, debugging, accessibility audits, and bidirectional design-token workflows across local, remote read-only, and paired cloud modes; it is not a generic one-click Figma-to-code exporter.

OpenUI

Open-source UI generation from natural-language prompts

OpenUI is an Apache-2.0 design-to-code tool from W&B that turns natural-language interface prompts into live HTML previews and frontend code. Teams can run it locally or with Docker, connect OpenAI, Groq, LiteLLM-compatible providers, or Ollama, and export generated UI toward React, Svelte, Web Components, and related workflows. It fits rapid UI mockups where developers want editable code instead of screenshots.

Figma MCP Server

Official remote MCP server for design-to-code and write-to-canvas Figma workflows.

Figma MCP Server is Figma’s official remote Model Context Protocol surface for design-to-code agents. It gives supported clients structured design context, variables, components, selected-frame code context, Code Connect mappings, and beta write-to-canvas tools for creating or updating native Figma frames from an MCP client while keeping the workflow tied to Figma files.
