About:
Oat++ (oatpp) is a modern C++ web framework focused on high performance and minimal memory footprint. It enables developers to build scalable REST APIs and microservices without relying on external dependencies or heavy runtime overhead. The framework emphasizes zero-copy and lazy evaluation to maximize efficiency in resource-constrained environments.

Key Features:

High-performance with zero-copy and lazy evaluation
No external dependencies (lightweight core)
Automatic DTO serialization/deserialization
Embedded-friendly (can run on constrained devices)
Multi-threaded and asynchronous I/O support

Use Cases:

Building high-performance REST APIs and microservices
Creating embedded web servers on constrained hardware
Developing low-latency networked applications
Prototyping C++ web services with minimal setup

Alternatives:

Boost.Beast – Part of Boost; provides low-level HTTP/WebSocket primitives but requires more boilerplate than Oatpp's integrated framework approach.
Pistache – Modern C++ HTTP/REST library; similar goals but Oatpp often favored for its smaller footprint and embedded use cases.
