Flask AI SaaS Starter — Multi-Provider OAuth + Groq LLaMA 3.3

A production-ready Flask web application built from scratch with real OAuth2 authentication and a blazing-fast AI chat interface powered by Meta's LLaMA 3.3 70B via Groq!
It's a SaaS template that covers everything a real client project needs, from secure login to persistent database storage.
Tech Stack:
→ Python & Flask 3.0
→ Groq API + Meta LLaMA 3.3 70B
→ Google OAuth2 + X (Twitter) OAuth2 with PKCE + PlayStation Network OAuth2(PSN OAuth requires Sony partnership, demo shows the flow.)
→ Flask-SQLAlchemy + Flask-Migrate
→ Flask-Session (server-side sessions for secure OAuth flows)
→ SQLite database with User and ChatMessage models
→ HTML, CSS, JavaScript — zero frameworks
What you'll build:
→ Real OAuth2 login with Google and X — not demo, actual authentication
→ PKCE flow for Twitter (the secure way big apps do it)
→ AI chat that remembers your full conversation history across sessions
→ Database that persists every user and every message automatically
→ Demo login mode for instant testing without credentials
Possible with OpenAi as well.
