Colir

Colir is solving a problem every designer has quietly fumes about: every gradient tool spits out the same flat linear stops, and none of them let you actually sculpt the feel. This one gives you curve-based control on X and Y axes with real-time WebGL rendering, so you're not guessing what'll look like when it actually renders — you see it instantly, then layer on noise, sparkle, feather, or distortion for texture that other tools wouldn't touch with a ten-foot pole. $49 perpetual license with lifetime updates is genuinely fair pricing, though with only 85 users so far, this is very much still in the early innings — but the concept is solid and the maker clearly knows the pain point firsthand.
