ROOST is a not-for-profit open source tooling hub designed to empower trust and safety engineers by providing ready-to-deploy software to avoid reinventing the wheel whenever they need to develop a new tool. Just as open source helped software development to evolve into a field characterized by collaboration and rapid innovation, the trust and safety field has the potential to redefine itself through open source. The support for ROOST since its launch makes one thing clear: the trust and safety community recognizes that an open source tooling hub can elevate the entire sector and help cultivate a resilient ecosystem—one where shared responsibility, resources, and intelligence pave the way for safer digital spaces.
