Framer
A free component on the Framer Marketplace: four transitions, the images from Framer's picker, and the rest in the panel on the right.
A component of its own, free on the Framer Marketplace: Shader Image Slider. Copy Component, paste it into a page, and the panel on the right has the rest: the images, from Framer's picker; the transition, Liquid, Burn, Ripple, Glitch or a fade; autoplay, loop and the time of a move; arrows, dots, Fill or Fit, the corners; and buttons on it that let a visitor try the transitions.
It draws in Preview and on the published site; on the canvas of the editor it is the first picture, standing still. Images from Framer's own store are drawn by the canvas; an image from another site is drawn when that site sends CORS, else the slides fade. The free component has a small link to gpuslider.com in a corner.
Try it first: the preview. The code is framer/GpuSlider.tsx in the repository, to paste into a code file of a project (Assets → Code), as it is or changed.
