AI SaaS billing loop demo
AI Workstation Credits MVP
A deployable Next.js and Supabase demo for the core product loop: auth, credits, secure backend AI calls, usage logs, and admin recharge.
Real Supabase auth is connected. The AI route is backend-only and uses a server-only DeepSeek key when configured, with a local demo fallback for no-secret reviewer environments.
