Feature Comparison

Feature	Supabase	Vercel
Primary Focus	Complete backend infrastructure with PostgreSQL database, authentication, storage, and APIs	Frontend deployment and hosting with global CDN, optimized for Next.js and React applications
Database & Data Storage	Full PostgreSQL database with auto-generated REST/GraphQL APIs, real-time subscriptions, and Row Level Security	No native database; requires integration with external database services or uses Vercel KV/Postgres add-ons

Deployment & CI/CD	Hosts backend services; requires separate frontend deployment solution	Zero-configuration deployments with automatic Git integration, preview URLs for every branch, and instant rollbacks
Serverless Functions	Edge Functions (Deno-based) for custom backend logic and API endpoints	Serverless Functions with automatic scaling, optimized for API routes and backend logic with Node.js runtime
Real-time Capabilities	Native real-time subscriptions for database changes with WebSocket support built directly into PostgreSQL	No native real-time features; requires custom implementation or third-party services like Pusher or Ably

Pricing Comparison

Both platforms offer generous free tiers suitable for small projects, with Supabase providing $0/month for backend services and Vercel offering free frontend hosting. Costs scale differently: Supabase charges based on database usage, storage, and bandwidth, while Vercel pricing increases significantly with traffic and serverless function executions, potentially becoming expensive for high-traffic applications.
