EaaSI

/ˈizi/ ('eezee)

An open‑source platform that lets galleries, libraries, archives and museums deliver browser‑based access to emulated computing environments so users can run legacy software and interact with digital collections. The program is led by Yale Library’s Software Preservation & Emulation unit; it began in 2018 with support from the Mellon and Sloan foundations and is now an ongoing Yale initiative. EaaSI builds on the Emulation‑as‑a‑Service (EaaS) framework (originally developed at the University of Freiburg) and offers a web sandbox to simplify running multiple emulators in a browser. It enables a network for sharing pre‑configured environments and supports “virtual reading room” access workflows across partner institutions. In Australia, AusEaaSI extends the platform to GLAM organisations via AARNet, providing shared, browser‑based access to born‑digital cultural collections.
