Why this exists
Most CSS generators still spit hex from 2016. You copy, then rewrite it into oklch and Tailwind before you can commit.
The three failures
1 Output you would not ship
Named hex, muddy midpoints, no Tailwind v4. You spend longer cleaning the snippet than writing it.
2 One job per site
Color here, shadow there, clip-path in a third tab. None of them share values, and none of them match the rest of the file.
3 An account to copy
A watermark, a daily cap, a modal. The generator should finish. There is nothing to upload and nothing to sign in for.
What you get
These tools run in the browser. Output is CSS first, with Tailwind next to it, and a layout playground if you want to see the property instead of only copying it. No account.
