Sebastian Software GmbH from Mainz and Heidelberg specializes in large web applications based on ReactJS and GraphQL. These include for example online banking, online shops, administration interfaces, social networks, media libraries, etc.

Since modern web applications always need an eye for detail, the topic of colors is also very important to us. It is part of our philosophy to tackle things correctly. Therefore we are also very engaged in the OpenSource-community. The openness of software fits to our wish to treat colors openly and to make them usable.

Our customers include for example: “Deutsche Bank”, “Otto Group”, “ARD”, “VW/MAN” and “Huawei”. You can find out more at:
