LEGEND Project Overview

LEGEND Project Overview

On November 20, 2019, at FINOS' flagship Open Source Strategy Forum, FINOS Platinum member Goldman Sachs announced its intention to open source its internally developed Legend data management platform into FINOS. The Legend code was open sourced and contributed into FINOS in October 2020 and is now available at github.com/finos/legend for anyone to use and contribute to.

Use the form below to request an account on the FINOS shared (public) instance of Legend.

The shared instance of Legend 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. Please read the Terms of Service for more information.

Anyone is welcome to request an account on the shared instance. Requests for accounts will be fulfilled based on FINOS staff availability as well as the rationale stated below for wanting an account and/or any connection between a request and the work of an ongoing FINOS project. Additional consideration will be also given to account requests from FINOS members.

FINOS reserves the right to pause, throttle, and/or group requests into limited availability tranches based on demand, load, and/or FINOS capacity.
