All of Rainbox Lab’s software is available licensed under the GNU General Public License (GNU-GPL).
You can read this license here, and donwload it too.

The Foundations of the GPL

Nobody should be restricted by the software they use. There are four freedoms that every user should have:

1st freedom

the freedom to use the software for any purpose,

2nd freedom

the freedom to change the software to suit your needs,

3rd freedom

the freedom to share the software with your friends and neighbors, and

4th freedom

the freedom to share the changes you make.

For users

The first freedom guarantees that you can use the software as you wish, for any work, either it’s commercial, or personal, or non-profit. Works made with the help of our tools are yours and you can do what you want with them.

You don’t need any authorization or contract. Download, install, have fun!

Just know that we’re very curious to see what you’ve made with our tools, so you can send us the result of your work! You can help the developement of the free tools too, with a donation or buying some items in the shop.

For developpers

The second freedom lets you change the software as you need. You can get the source code on github.

The third and fourth freedoms let you share our tools and distribute them yourself, with or without your changes. However, in order to keep those four freedoms, the GNU General Public License restricts the release of the tools (including your changes) under a compatible license, one which guarantees these four freedoms too. Thus, you can neither sell the tools, nor keep the source code private. You must list all the authors of the free software you share and change too. In short, the tools, with or without changes, must stay free.

If you include any part of the source code of our tools – even a short part – in your own tools, they must be released under a free software license too. You cannot sell any software including some code licensed under a free license.

Support us!

Our tools are free, as in free beer as well as in freedom.

But unlike most of the free stuff you can find on the internet, there’s no advertising at all, and you are not the product here. We just work in a non-mercantile way, and consider sharing as a great value. It is important for us that our tools are available for everyone, rich or poor, amateur or professionnal. Because our greatest wish is to see great films, and we believe sharing and helping each other is the easiest way to make it come true.

The difficult part is that developping, maintaining, distributing these tools is a lot of work and investment. The only funds we get for all of this are your kind contributions.

There are two ways for sending your support: you can either send a one-time donation to Rainbox, or make a small but regular donation to Duduf on Patreon, where you’ll be in direct contact with him and get an early and exclusive access to all the stuff he’s developping and working on.
