v0: The UI Component Factory

v0 by Vercel specializes in generating beautiful, production-ready React components. Describe a UI element — a dashboard, a pricing page, a data table — and v0 generates polished code using shadcn/ui and Tailwind CSS.

Strengths

• Production Quality — Generated components are clean, accessible, and ready to drop into real projects.
• shadcn/ui + Tailwind — Uses the most popular React component library and CSS framework.
• Iterative Refinement — Chat with v0 to tweak components, change layouts, and adjust styling.
• Vercel Integration — Deploy instantly to Vercel with one click.
• Code Export — Copy generated code directly into your project. No lock-in.

Weaknesses

• Frontend-only — no backend, database, or API generation
• Limited to React/Next.js ecosystem
• Cannot build complete applications end-to-end
• Credit limits on free and lower tiers

Bolt.new: The Full-Stack Builder

Bolt.new runs a complete development environment in your browser. It can create full-stack applications with frontend, backend, and package management — all from natural language descriptions.

Strengths

• Full-Stack — Generates frontend, backend, API routes, and database schema in one session.
• In-Browser IDE — Full VS Code-like editor with terminal, file system, and package management.
• Multi-Framework — Supports React, Vue, Svelte, Angular, Astro, and more.
• Live Preview — See your app running in real-time as the AI generates code.
• npm Integration — Install and use any npm package automatically.

Weaknesses

• Token limits can run out quickly on complex projects
• Generated code sometimes needs manual debugging
• No built-in database hosting
• Preview deployments are temporary

Lovable: The Non-Coder’s Dream

Lovable (formerly GPT-Engineer) aims to make app building accessible to non-technical users. It generates full-stack applications with Supabase backends and offers one-click deployment.

Strengths

• No-Code Friendly — The most accessible interface for people without programming experience.
• Supabase Integration — Built-in database, authentication, and storage through Supabase.
• One-Click Deploy — Deploy your app to production with a single click.
• Visual Editor — Make changes visually without touching code.
• GitHub Sync — Code is synced to a GitHub repo that you own.

Weaknesses

• Locked into React/Next.js + Supabase stack
• Less control for experienced developers
• Complex applications may hit generation limits
• Newer platform with a smaller community

Which Should You Choose?

v0 — Frontend developers who need beautiful UI components fast. Best for teams already using React, Next.js, and Vercel.

Bolt.new — Developers who want to prototype full-stack applications quickly with maximum framework flexibility.

Lovable — Non-technical founders, designers, and product managers who want to build MVPs without writing code.
