QBit

Benchmarks in the README highlight QBit's ability to handle millions of calls per second, with optimizations like micro-batching and efficient queue management for high-throughput microservices.

Provides built-in support for service discovery, health checks, and a strongly-typed event bus, enabling elastic, cloud-native architectures without relying on a full framework.

As a library, QBit can be mixed with existing tools like Spring or Guice, allowing incremental adoption and avoiding vendor lock-in while maintaining control over threading.

Offers fast async RPC over WebSocket with client proxy generation, supporting high-speed communication ideal for real-time applications and mobile backends.
