You will be glad to know that I have just released an Open Source edition of Chevereto called "Chevereto Free". This new edition is released under the AGPLv3 and it includes the same core functionalities of Chevereto's paid edition.
Chevereto Free is all about make Chevereto more universal and empower more people with it. At this time Chevereto is the base system of more than 7,000 image hosting websites and hopefully that number will skyrocket thanks to this new Open Source edition.
Chevereto Free code is available at GitHub, grab it today.
