Ranked list

1.A
Replit
Browser IDE with Replit Agent that builds and deploys full apps.
Most complete build-and-host loop for vibe coders; usage costs can surprise.
2.A
v0
Vercel's AI app and UI builder that deploys to Vercel.
Best-looking React/Next.js output and one-click Vercel deploys.
3.B
Base44
No-code AI app builder with built-in backend, auth and hosting (Wix-owned).
All-in-one backend makes it easy for non-coders; less portable code.
4.B
Bolt.new
In-browser AI app builder with hosting and databases, by StackBlitz.
Great for prototypes; token burn on larger projects keeps it out of A.
5.B
Lovable
Chat-to-full-stack-app builder for web apps and sites.
Fastest path from idea to deployed app for non-coders; harder to steer on complex apps.
6.B
Anything (formerly Create)
AI builder for web and mobile apps from a prompt.
Ships native mobile apps as well as web; smaller ecosystem.
7.B
Firebase Studio
Google's cloud agentic workspace to prototype and ship full-stack apps with Gemini.
Strong if you're already on Firebase/GCP; less polished than Lovable for non-coders.
8.B
Rork
AI builder for native iOS/Android apps with React Native.
Go-to vibe-coding tool for mobile apps.
9.C
Softgen
AI web app builder for full-stack Next.js projects.
Niche Lovable alternative; pricing page client-rendered.
