Top 10 C++ Frameworks for Web Development: Advanced Level

C++ is traditionally associated with system programming, games, and high-load computing. However, recent years have seen a renaissance of C++ usage in web development. Thanks to new standards (C++17, C++20, C++23) and the emergence of modern frameworks, C++ is becoming a powerful tool for creating high-performance web servers, REST APIs, and microservices. In this article, we will look at the top 10 C++ frameworks for web development, targeting advanced developers who value speed, efficiency, and low memory consumption.

1. Drogon: Asynchrony and Performance

Drogon is one of the most popular modern C++ web frameworks. It is built on an asynchronous I/O model (based on libuv) and supports HTTP/1.1, HTTP/2, WebSocket, as well as database integration (PostgreSQL, MySQL, SQLite3). The framework uses C++ templates to generate routing code, ensuring minimal overhead.

Key Features:

• Non-blocking asynchronous request processing
• Built-in support for JSON, ORM, CORS
• Automatic OpenAPI documentation generation

// Example of a simple controller in Drogon#include <drogon/drogon.h>using namespace drogon;

int main() {    app().registerHandler("/hello",        [](const HttpRequestPtr& req,           std::function<void (const HttpResponsePtr&)> callback) {            Json::Value json;            json["message"] = "Hello, C++!";            auto resp = HttpResponse::newHttpJsonResponse(json);            callback(resp);        });    app().addListener("0.0.0.0", 8080).run();    return 0;}

2. Crow: Minimalistic and Fast

Crow is a lightweight C++ micro-framework inspired by Python Flask. It is ideal for creating simple REST APIs and prototypes. Crow has no complex dependencies and compiles almost instantly. It supports routing, middleware, WebSocket, and Mustache templates.

Key Features:

• Very simple API reminiscent of Flask
• Support for C++14 and above
• Built-in HTTP server based on Boost.Asio

// Example REST API on Crow#include "crow.h"

int main() {    crow::SimpleApp app;

    CROW_ROUTE(app, "/api/data")([](){        crow::json::wvalue x;        x["status"] = "ok";        x["value"] = 42;        return x;    });

    app.port(18080).multithreaded().run();}

3. Pistache: Modern HTTP Server

Pistache is a framework focused on creating high-performance HTTP servers using modern C++ features. It provides a clean, type-safe API for request handling, session management, and WebSocket operations. Pistache actively uses RAII and exceptions.

Key Features:

• Asynchronous processing based on epoll/kqueue
• Support for HTTPS and HTTP/2
• Flexible middleware system

// Simple server on Pistache#include <pistache/endpoint.h>using namespace Pistache;

class HelloHandler : public Http::Handler {public:    HTTP_PROTOTYPE(HelloHandler)    void onRequest(const Http::Request& request, Http::ResponseWriter writer) override {        writer.send(Http::Code::Ok, "Hello from Pistache!");    }};

int main() {    Http::listenAndServe<HelloHandler>("*:9080");}

4. Wt (Web Toolkit): Desktop Application in the Browser

Wt is a unique framework that allows developing complex web interfaces in C++ without using JavaScript. It translates C++ code into HTML/JavaScript on the server side, supporting AJAX, WebSocket, and widgets. Wt is ideal for s
