Pros & cons
- +StackBlitz WebContainer runs real Node.js in your browser — no cloud workspace needed
- +Framework flexibility — React, Next.js, Vue, Svelte, Astro
- +Code transparency: you see + edit the actual files between prompts
- −Less polished UI defaults than Lovable
- −Steeper learning curve for true non-engineers
- −Backend story less integrated than Lovable + Supabase
- +Native GitHub integration — apps deploy with one click

- +Best for "personal apps" use case (Slack tools, side-project utilities)
- −Newer than Lovable/Bolt — fewer templates and patterns
- −Less flexible than dedicated builders for production apps
- −Limited to specific app shapes — not a general-purpose builder yet
