⚡ gRPC

When to Choose gRPC

gRPC excels in these scenarios:

• Microservices Communication: Internal service-to-service calls
• Real-time Streaming: Live data feeds, chat, notifications
• Mobile Backends: Efficient binary protocol saves bandwidth
• Polyglot Systems: Services in different languages need to communicate
• High-Throughput APIs: When REST/JSON becomes a bottleneck

gRPC vs REST: When to Use Which

My recommendation: Use gRPC for internal microservices, REST for public APIs. I can help you design hybrid architectures that use both.

Frequently Asked Questions

What is gRPC development?

gRPC is a high-performance RPC (Remote Procedure Call) framework using Protocol Buffers for serialization. gRPC development involves: defining service contracts, implementing servers and clients, and building efficient microservice communication.

How much does gRPC development cost?

gRPC development typically costs $110-160 per hour. A basic service implementation starts around $10,000-20,000, while complex microservices architectures range from $40,000-100,000+.

gRPC vs REST, when should I use each?

Use gRPC for: internal microservice communication, high-performance requirements, bidirectional streaming, or strongly-typed contracts. Use REST for: public APIs, browser clients, simple CRUD operations. gRPC is faster; REST is more universal.

What languages do you work with for gRPC?

I work with gRPC in: Python, Go, Java, Node.js, and TypeScript. Protocol Buffer definitions generate code for all languages, enabling polyglot microservices.

How do you handle gRPC in browser clients?

Browsers can’t directly use gRPC. Options: gRPC-Web (proxy-based), REST gateway that translates to gRPC, or GraphQL frontend with gRPC backends. I recommend gRPC for service-to-service and REST/GraphQL for web clients.
