Our Kickstarter was funded! Continue supporting the Virtual Worlds Museum™ through our Sponsor Page.
Open Cobalt is a free and open-source software platform for constructing, accessing, and sharing virtual worlds both on local area networks or across the Internet, with no need for centralized servers.
Open Cobalt was an open‑source virtual world platform focused on education, collaboration, and scientific visualization. Its cultural impact lies in promoting decentralized, peer‑to‑peer virtual environments long before Web3 discourse. It influenced academic and research‑driven virtual world projects, emphasizing openness and interoperability. Open Cobalt helped shape the idea of virtual worlds as shared knowledge spaces rather than commercial products.
