Shared Public Instance of Legend Studio​

FINOS hosts a shared instance of Legend Studio at https://legend.finos.org/studio. The shared instance of Legend Studio is provided free-of-charge and as-is. It is primarily intended to be used for shared modeling efforts conducted by FINOS members and other non-member community participants as part of FINOS hosted projects or initiatives.

Learn about the projects that are currently leveraging the shared instance of Legend Studio in the "modeling initiatives" section of the FINOS Landscape. The shared instance was also used by participants in the FINOS Legend Studio pilot (April-September 2020).

Anyone is welcome to request an account on the shared instance.
