Nyans, a LUT Lab in the Browser

Why it surfaced

This is unusually ambitious browser software: it offers reorderable grading nodes, contact-sheet previews, reference matching, LUT reverse-fitting, camera log transforms, and seven export formats. The site also makes a concrete privacy-and-cost proposition—uploads are listed as 0 bytes, files stay on the machine, and the grading happens locally.

Nyans is a free, browser-based color-grading tool for screenshots, RAW, log, HDR, and video files, with exports for .cube, .3dl, Unreal, Unity, ReShade, and HALD.
