drogon

Drogon: A C++14/17/20 based HTTP web application framework running on Linux/macOS/Unix/Windows

Project mention: Experience using crow as web server | /r/cpp | 2023-11-06

I looked at oatpp and drogon, which are both great, but feel too high-level for my purposes. I tried drogon and got something working, but it feels like too much for my requirements, as in particular I'd like to slot in my choice of Json and message-body handling. C.f. the simple approach in Crow, which I easily understand and build on.
