Traditional Backend:

• Requires setting up and maintaining servers
• Need to write API endpoints manually
• Database management and optimization
• Manual scaling and infrastructure management
• Separate authentication implementation
• Custom real-time functionality implementation

Firebase:

• Serverless - no server management needed
• Pre-built APIs and SDKs
• Managed databases with automatic scaling
• Built-in authentication system
• Real-time synchronization out of the box
• Pay-as-you-use pricing model
• Faster development and deployment
