01
From one file to a project.
Run a C++ source file directly, or use Vix.cpp with a complete project.
- Run a single .cpp file with vix run.
- Build and test project targets.
- Existing CMake projects can remain CMake-first.
A runtime for C++ applications.
Vix.cpp provides a coherent way to build, run, and operate C++ applications throughout their lifecycle, while working with the C++ ecosystem you already use.
02
Manage project dependencies.
Install and lock C++ dependencies without replacing the build system your project already uses.
- Install Registry or Git dependencies.
- Use installed dependencies from existing CMake projects.
- Keep resolved dependency state in vix.lock.
03
From build to production.
Build, deploy, and operate C++ backend applications through the Vix.cpp workflow.
- Deploy with vix deploy.
- Manage services, reverse proxies and health checks.
- Inspect production state and logs with vix.

Why Vix.cpp?
Vix.cpp works with the C++ ecosystem you already use, while giving applications a clearer lifecycle and better visibility when something goes wrong.
Keep your C++ stack.

Vix.cpp
Vix.cpp
Use CMake, GCC or Clang, and the C++ libraries your project already depends on. Vix.cpp does not require you to move into a separate ecosystem.
One application lifecycle.
build→run→test→deploy→inspectVix.cpp
Use the same Vix.cpp workflow as the application moves from development to execution and production.

causelocationhint
Vix.cpp connects failures from different parts of the application lifecycle to the cause, location, and information you can act on.
Build it in Vix.cpp
Vix.cpp focuses on two areas where it is designed to provide a clear development experience from the first lines of code to a complete project.
Web & Networked Applications
Build connected applications in C++ with a development workflow that remains clear as the project grows and reaches production.
Developer Tools
Build tools in C++ without making project setup, dependencies, testing, and distribution the hardest part of the work.
Vix.cpp in production
Vix.cpp is built for real C++ applications that move beyond development and need to keep running. Its production experience is shaped by real-world use, continuous validation, and the problems that appear when software is deployed and operated over time.
Latest release
Vix.cpp v2.9.0
A release about ownership.
Vix.cpp v2.9.0 clarifies responsibility across the build system, networking, SDK packaging, and mobile platform support.
Build
Vix focuses on project intent while CMake and Ninja own the concrete compilation graph.
Requests
The asynchronous HTTP path now remains asynchronous throughout the operation.
SDKs
SDKs own more of their internal dependencies and expose a cleaner consumer contract.
Mobile
Android and iOS support works with their native Gradle and Xcode toolchains.
