WebSockets vs gRPC

The real-time whisperer meets the microservices whisperer: blazing fast, but good luck debugging that binary blob. Here's our take.

WebSockets

Nice Pick

The real-time whisperer. Because polling is so 2005, but debugging this can feel like time travel.

Pros

• Enables low-latency, bidirectional communication without HTTP overhead
• Widely supported across modern browsers and servers
• Persistent connections reduce server load for real-time apps

Cons

• Debugging can be a nightmare with opaque connection drops
• Scaling requires careful state management and can get messy fast

gRPC

The microservices whisperer: blazing fast, but good luck debugging that binary blob.

Pros

• High-performance with HTTP/2 and Protocol Buffers
• Built-in support for streaming and load balancing
• Strong typing and code generation across multiple languages

Cons

• Binary payloads make debugging a nightmare
• Steep learning curve for Protocol Buffers and HTTP/2 quirks

The Verdict

These tools serve different purposes. WebSockets is a real-time communication while gRPC is a frameworks. We picked WebSockets based on overall popularity, but your choice depends on what you're building.

The Bottom Line

WebSockets wins

Based on overall popularity. WebSockets is more widely used, but gRPC excels in its own space.
