Objective: To introduce and demonstrate a software library for time-optimal gradient waveform optimization for a wide range of applications. The software allows for direct just-in-time gradient waveform design on scanner hardware for multiple vendors. The software is tested over a range of constraints and acquisition types for which compute times are on the order of (1-100ms). The sequences are also implemented on two different vendor scanners, demonstrating the interoperability of the method.
