See your layers scroll at real parallax speeds.

Parallax Tester

Upload a tileset for the ground (layer 0), a character to stand on it, background layers (-1, -2, -3 and deeper), a static far background (-99), and foreground layers (1 and up). Everything loops seamlessly on a 1920 x 1080 stage.

Fully in-browser. Backgrounds authored at 2880 x 1080 work great.
