A visual live-programming environment that takes you from rapid prototyping to final production.

Visual Live-Programming with vvvv

Very Visual

vvvv is a visual-first live programming environment for the .NET ecosystem. Its language VL combines metaphors known from dataflow, functional and object oriented programming.

There is no need to write any code, unless you really want to.

Inherently Fast

vvvv programs are compiled and run on the .NET virtual machine. As such they are as fast as if you’d write them in C#.

Want to use all the cores of your CPU? With VL it requires no rocket science to have parts of your program run on separate threads.

Quick To Iterate

vvvv has one mode: Runtime. Modify your program while it is running, compilation happens in the background.

With its state hot-reload technology, vvvv saves you precious time: There is no need to restart your program to see the effects of changes you make.

Ready To Connect

vvvv comes with support for many hardware devices, like color and depth cameras, the serial port,…

Also, it speaks most common protocols, like OSC, UDP, TCP, Art-Net, ZMQ, MQTT, Websocket, HTTP, RCP,…

Open To Extend

vvvv can be extended with custom nodes written in pure C#. No proprietary plugin-wrapping boilerplate code is needed.

This allows you to directly consume almost any .NET library from nuget.org, without having to write a single line of code.

Proven To Perform
vvvv’s initial release was in 2002. It is since in use by people around the world to build live-shows and permanent installations.
Built To Be Learned

vvvv comes with a built-in HelpBrowser that gives you direct access to examples and explanations. A series of video tutorials provides you with the fundamentals in no time.

If you need a hand, a caring community is waiting for you to join. vvvv’s chat and forums are both open 24/7.
