In Depth
Convex
Convex replaces your database, API layer, and real-time sync with a single TypeScript platform. You write queries and mutations as TypeScript functions, and your React frontend automatically re-renders when data changes - no websocket setup, no polling. It includes scheduled functions (cron jobs), file storage, full-text search, and vector search for AI apps. This site uses Convex for the course database (90 lessons), video catalog, AI news feed, and user management. The cron job syncs new YouTube videos daily at midnight. Free tier includes 1M function calls/month.
Clerk
Clerk handles authentication on this site. It provides pre-built React components for sign-in, sign-up, and user profile management. Integration with Next.js is seamless - wrap your app in ClerkProvider, add SignInButton, and you're done. It handles OAuth (Google, GitHub), email/password, MFA, session management, and user metadata. The developer experience is genuinely good - I chose it for this site before I ever made a video about it. Free tier supports 10K monthly active users.
