Legend Studio is a web-based application that serves as the graphical interface for the Legend platform, enabling users to model, visualize, and interact with data models and queries. It is designed for developers, data engineers, and modelers who need a user-friendly tool to work with Legend's data modeling and query capabilities. The project is part of the FINOS (Fintech Open Source Foundation) ecosystem and is built with extensibility in mind, allowing for custom extensions and integrations.
