gRPC is an open‑source, high‑performance remote procedure call (RPC) framework that works across many languages and platforms. It uses Protocol Buffers for efficient serialization and supports features like streaming, authentication, and load balancing.

Use cases

• build low‑latency microservice communication
• create streaming APIs for real‑time data feeds
• connect mobile or web clients to backend services via HTTP/2
• generate client libraries in multiple languages from a single .proto definition
• implement secure, authenticated RPC endpoints

When to choose

• you need language‑agnostic, high‑throughput communication between services
• your system requires bi‑directional streaming or flow control
• you want automatic code generation for client and server stubs
• you need built‑in support for load balancing, health checking, and tracing

When to avoid

• you prefer a simple REST/JSON API over binary protocols
• your environment cannot support HTTP/2 or the required runtimes
• you need a lightweight solution for tiny embedded devices with minimal dependencies
