Free, in-browser design tools · no signup

Catch the inconsistencies your design system was supposed to prevent.

I'm building a small kit of free tools for people who care about design consistency. First up: a checker that reads any site's CSS — including whatever an AI just generated — and tells you how cohesive it really is, then hands you a tighter set of tokens. More tools are on the way, and further out, a way to get real designers to review your work.

Design System Consistency Checker

Paste the CSS from any site — including whatever an AI just generated for you — and get a read on how consistent it really is. Nothing is uploaded; the CSS never leaves your browser.

Suggested tokens

A tighter starting set, pulled from what you already use.

Contrast & accessibility checker

Paste your palette — hex, rgb, hsl or named colours, in any format — and see every text/background pair graded against WCAG AA and AAA. When a pair falls short, you'll get the nearest colour that passes.

Every pair, graded

Row colour is the text; column colour is the background. The ratio reads the same both ways.

Pairs to fix

More tools on the way

Same idea as the checker: small, sharp, free, and running right in your browser.
Spacing auditorComing soon

Find the stray 13px hiding among your 12s and 16s, and snap a drifting layout back onto a clean 4- or 8-point rhythm.

Type scale builderComing soon

Turn the font sizes already in your CSS into a coherent modular scale, with tokens and a live specimen you can preview.

Token diffComing soon

Compare two stylesheets — a before and after, or two branches — and see exactly which colours, spacings and radii drifted apart.

Got a tool you wish existed? That's the shortlist I'm working from — the roadmap will grow.

What's next

On the roadmap

The tools tell you what is inconsistent. The longer-term plan is to help with the harder part — taste. Designer Checked will grow into a place where real designers review real work.

Upload & get reviewedLater

Share a screen, a flow, or a whole file and get honest, specific feedback from a working designer — not a rubric, and not a comment-thread pile-on.

Review as a designerLater

Experienced designers will be able to apply to join the reviewer pool — do work you're good at, on your own schedule, and get paid for it.

Signups aren't open yet — the tools come first. This page will be where it all lands.
