Vix.cpp Build real applications with modern C++. Vix.cpp is a modern C++ runtime for building fast, reliable, production-ready applications. Website · Docs · Registry · Engineering notes

Vix.cpp removes friction from C++ application development. It gives C++ a modern application workflow while keeping native performance, explicit control, and production-oriented architecture.

Vix is not just a web framework. It is a runtime foundation for backend services, AI agents, games, P2P systems, local-first applications, fast builds, templates, and production-ready C++ projects.

Install

Shell, Linux and macOS:

curl -fsSL https://vixcpp.com/install.sh | bash

PowerShell, Windows:

irm https://vixcpp.com/install.ps1 | iex

More installation options:

https://vixcpp.com/install

Quick start

Create server.cpp:

#include <vix.hpp>
using namespace vix;

int main()
{
    vix::App app;

    app.get("/", [](Request &req, Response &res) {
        res.send("Hello from Vix.cpp");
    });

    app.run(8080);

    return 0;
}

Run it:

vix run server.cpp

Open:

http://localhost:8080

Why Vix.cpp ?

C++ is powerful, but building real applications often means rebuilding the same foundation again and again.

Vix gives you that foundation:

• run C++ files with vix run
• create projects with vix new
• build fast with vix build
• build backend services
• build WebSocket applications
• build P2P systems
• build AI agents
• build game-oriented projects
• use threadpool and async runtime modules
• use KV, cache, database, ORM, middleware, crypto, validation, and template modules
• generate production-ready backend projects
• integrate backend projects with frontend apps such as Vue.js

Runtime modules

agent        async        cache        cli          conversion
core         crypto       db           env          error
fs           game         io           json         kv
log          middleware   net          orm          os
p2p          p2p_http     path         process      reply
sync         template     tests        threadpool   time
utils        validation   webrpc       websocket

Vix.cpp is designed as an application runtime layer, not only as an HTTP server.
