Modern engineering requires a multitude of specialist software tools. But as of yet, this “toolchain” consists almost entirely of commercially developed application programs, which increasingly can only be procured through expensive subscription models. Furthermore, their publishers try to drive customers into dependence through non-open (proprietary) file formats and cloud platforms (vendor lock-in). We envision a world where all tools are intercompatible and have respective open formats.
unfortunately not all tools listed on that website are entirely trade-free. That’s why this service is rejected for now. Something can be open-source but still include some ads or trackers. When something is trade-free that means that these trades do not exist.
