Replit Agent + Supabase

Cheap to start, dev-forward. Fewer batteries included for production polish.

$47/mo

31% more than cheapest

Vercel + Supabase + OpenAI direct

Two vendors to babysit. AI costs stack fast at scale unless you cache aggressively.

$65/mo

79% more than cheapest

Webflow + Xano + OpenAI

Beautiful marketing site plus a real backend, but two subscriptions and a bridge to maintain.

$101/mo

178% more than cheapest

Bubble.io

Fast to click together, hard to shape once you outgrow the box. Workload units get expensive.
