1. When to Choose Lovable (Full Review)
Lovable is the strongest choice when you are building a software product that needs user authentication and a database. Its native Supabase integration lets you prompt login flows, row-level security, and CRUD dashboards without touching a terminal.
Where people get stuck: Using Lovable for a local business website or marketing page. Because Lovable outputs a client-side React single-page application by default, search engine crawlers and AI assistants often see an empty shell unless you set up server-side rendering, and keeping a custom domain live costs USD 300/year on the Pro plan. See best Lovable alternatives.
2. When to Choose Bolt.new (Full Review)
Bolt.new runs StackBlitz's WebContainers inside your browser tab, giving you a real file tree, package.json, and terminal. If you are a developer who wants to scaffold an Astro, SvelteKit, or Vite app and inspect the code as it runs, Bolt.new feels immediately familiar.
Where people get stuck: Token burn during debugging loops. Because Bolt sends the project context back and forth on every fix, a single broken npm dependency can consume the 300,000 daily free token cap in 20 minutes. See best Bolt.new alternatives.
3. When to Choose v0 by Vercel (Full Review)
v0 excels at UI component generation for Next.js teams. If your engineering team already uses Tailwind CSS and shadcn/ui, v0 generates clean, accessible sections that drop right into your repository.
Where people get stuck: v0 writes generic placeholder headlines ("Streamline your workflow") rather than real business copy, and turning a v0 preview into a live business website with forms, legal pages, and domains requires deploying and maintaining a Vercel project. See best v0 alternatives.
