Crow

The routing syntax is directly inspired by Python's Flask, making API endpoint definition straightforward and reducing boilerplate code, as shown in the Hello World example.

URL parameters are type-checked at compile time, preventing runtime errors; the README includes an example where mismatched handler types cause a compile error.

Benchmarks linked in the README demonstrate that Crow outperforms other C++ and non-C++ frameworks, leveraging C++'s efficiency for high-speed web services.

Available as a single header file, Crow simplifies project integration without complex build systems, reducing dependency management overhead.
