Which should you use? A side-by-side look at what each one does, who it suits, what it costs, how hard it is to set up, and where each falls short.
Open source · MIT
A single-header C++11 library for building HTTP/HTTPS servers and clients.
Open source · MIT
A C++ web framework for building fast, asynchronous HTTP servers and REST APIs
The short answer
Choose cpp-httplib if you need…
- C++ developers who need a simple embedded HTTP server or client without a large framework
- Projects that want to avoid a complex build setup by using a single header file
- Teams that need HTTPS with a choice of OpenSSL, Mbed TLS, or wolfSSL
- Developers who want WebSocket, Server-Sent Events, or a stream API from the same library
Choose Drogon if you need…
- C++ developers building HTTP or REST API backends
- Teams that need non-blocking, high-concurrency network I/O in C++
- Projects that want built-in support for PostgreSQL, MySQL, SQLite, or Redis
- Developers who want controllers kept separate from the main program

What each one is
cpp-httplib
cpp-httplib is a C++ library you add to a project by including one header file, httplib.h. It lets a C++ program act as a web server or as a web client that sends HTTP and HTTPS requests. It uses blocking socket I/O and supports HTTP/1.1 only, and it can use OpenSSL, Mbed TLS, or wolfSSL for encryption.
Drogon
Drogon is a framework for writing web server programs in C++. It handles HTTP requests, routing to controller classes, JSON responses, WebSockets, and database access without blocking while waiting on I/O. People use it when they want a C++ backend or REST API and need the speed and control that C++ offers.
Best for
cpp-httplib
- C++ developers who need a simple embedded HTTP server or client without a large framework
- Projects that want to avoid a complex build setup by using a single header file
- Teams that need HTTPS with a choice of OpenSSL, Mbed TLS, or wolfSSL
- Developers who want WebSocket, Server-Sent Events, or a stream API from the same library
Drogon
- C++ developers building HTTP or REST API backends
- Teams that need non-blocking, high-concurrency network I/O in C++
- Projects that want built-in support for PostgreSQL, MySQL, SQLite, or Redis
- Developers who want controllers kept separate from the main program
Strengths
cpp-httplib
- Distributed as a single header file, so setup is just an include
- Supports HTTPS through three TLS backends: OpenSSL, Mbed TLS, and wolfSSL
- Documentation covers TLS error handling, custom certificate verification, and mutual TLS
Drogon
- Asynchronous, non-blocking I/O designed for high concurrency
- Controllers are decoupled from the main program, keeping main() short
- Broad built-in feature set: HTTPS, WebSocket, sessions, compression, ORM, and database clients
Not ideal for
cpp-httplib
- Apps that need non-blocking, high-concurrency socket I/O, since the README says this is blocking I/O and not the right choice for that
- Projects that need HTTP/2 or HTTP/3, which the README says are not implemented
- Targets that are 32-bit, since the README says 32-bit platforms are not supported and security reports for them are closed
Drogon
- Developers without C++ experience, since the code and build process are C++ only
- Projects that need a ready-made binary or installer, since the latest release lists no binaries
- Simple static sites or scripts where a higher-level language framework would be quicker to set up
Trade-offs
cpp-httplib
- Blocking socket I/O and HTTP/1.1 only, which rules out some workloads
- The README warns that 32-bit platforms are unsupported and not security reviewed
- Some TLS behavior differs by backend, such as wolfSSL's certificate enumeration limits, so the docs must be read per backend
Drogon
- Requires C++ knowledge and a C++ build environment, which is a steep learning curve for beginners
- The README's install instructions were not visible in the provided excerpt, so setup details must come from the full project docs
- Version support is stated inconsistently: the description says C++14/17/20, while the overview says C++17/20
