Blazor Hosting Models

Blazor offers two primary hosting models, each with distinct advantages and trade-offs.

Blazor Server

Pros:

• Smaller download size
• Full .NET runtime capabilities
• Better SEO support
• Works on older browsers

Cons:

• Requires constant server connection
• Higher server resource usage
• Latency on every interaction

Blazor WebAssembly

Pros:

• Runs entirely in browser
• Can work offline
• Reduced server load
• Better for PWAs

Cons:

• Larger initial download
• Limited to browser capabilities
• Longer initial load time

My Recommendation

Choose Blazor Server for internal enterprise apps with reliable networks. Choose Blazor WebAssembly for public-facing apps or when offline support is needed.
