Build an OpenAI-Style Paywall in FastAPI! 🔥 Redis + SQLite + Docker Full Demo with Real-Time Testing

Description

💥 Ever wondered how OpenAI, Stripe, or Notion protect their APIs from abuse and still make money? This video takes you behind the scenes of a production-grade FastAPI Paywall System — featuring rate limiting, API key tiers, Redis counters, SQLite usage tracking, and simulated billing — all running in Docker. You’ll learn how to: ✅ Use FastAPI + Redis to enforce real-time rate limits per user and per endpoint ✅ Track usage and monthly quotas in SQLite (your mini billing system) ✅ Test with real curl commands, debug via /debug/redis and /debug/sqlite, and visualize limits in action ✅ Scale the same design to Kubernetes + Postgres + Redis Cluster for real SaaS environments 💡 Whether you’re building a startup, SaaS product, or learning backend architecture — this project teaches how to make your API secure, monetizable, and future-proof. 🧠 Topics Covered: FastAPI Rate Limiting Middleware OpenAI-style API Paywall Architecture Redis for Real-Time Enforcement SQLite for Persistent Quotas API Key Authentication Docker Compose Setup Tier-based Free vs Pro vs Enterprise Access Testing with cURL & Postman Debugging Redis & SQLite ⚙️ Free Code Inside! Download, run, and test the entire project with just: docker compose up --build 👇 Watch till the end for advanced scaling tips and a cinematic explanation of how this architecture powers real-world SaaS APIs like OpenAI, Stability, and Anthropic. 🚀 Subscribe for more: FastAPI | Redis | LLM Projects Docker | AI Automation | Backend SaaS #FastAPI #Redis #SQLite #Docker #SaaS #API #RateLimit #BackendDev #OpenAI #APIPaywall #PythonProjects #SchoginiSystems #TechieTalksAI
