What is the best AI app builder for vibe coders?

We haven't picked one yet. Testing is in progress. The candidates we're testing are Lovable, Bolt, Replit Agent, v0 by Vercel, Base44. The tiers stay empty until every tool has run the same standardized test and the receipts are published.

How will VibeTierList rank each AI app builder?

Every tool gets the same task: Build a to-do app with login + database and deploy it; score: works, time, cost, exposed secrets. The prompt, budget, time limit and scoring sheet are identical for every tool.

Can a AI app builder pay to rank higher?

No. Payment never buys rank on VibeTierList. Sponsored content, if any, is always labeled and kept separate from the tiers.
