Ludvig af Klinteberg, Libin Lu, and others, have built FINUFFT.jl, an interface from the Julia language. This package supports 32-bit and 64-bit precision, and automatically downloads and runs pre-built binaries of the FINUFFT library for Linux, macOS, Windows and FreeBSD (for a full list see finufft_jll).
FINUFFT.jl has now (in 2022) itself been wrapped as part of NFFT.jl, which contains an “abstract” interface to any NUFFT in Julia, with FINUFFT as an example. Their performance comparison page show that FINUFFT matches their native Julia implementation for speed of type 1 and type 2 transforms in 3D, and beats NFFT, and with less precomputation. In 1D and 2D, the native Julia implementation is 1-2 times faster than FINUFFT in their tests on uniformly-random nonuniform points.
