Strengths & Weaknesses
Convex
Complete end-to-end type safety from database to frontend with automatic TypeScript code generation
Built-in real-time reactivity means UI automatically updates when data changes without manual websocket management
AI coding tools generate high-quality Convex code due to everything being TypeScript with clear conventions
Batteries-included platform with auth, file storage, cron jobs, and vector search reducing third-party dependencies
Relatively new platform compared to established alternatives like Firebase or Supabase with smaller ecosystem
Vendor lock-in concerns if using managed service despite open-source availability
Learning curve for developers unfamiliar with reactive programming paradigms
Supabase
Real PostgreSQL database with full SQL capabilities, advanced queries, triggers, and extensions—no proprietary NoSQL limitations
Generous free tier with no time expiration includes 500MB database, 50K auth users, and full feature access for unlimited projects
Auto-generated REST and GraphQL APIs from database schema eliminate boilerplate API code and speed up development significantly
Open-source with self-hosting option provides complete data ownership and eliminates vendor lock-in concerns
Free tier projects pause after 7 days of inactivity, requiring manual reactivation which can cause unexpected downtime
Bandwidth costs ($0.09/GB) and auth MAU overages ($0.00325/user) can escalate quickly for high-traffic applications with media content
Database-direct frontend access pattern requires careful RLS configuration and may not suit complex multi-tenant architectures
