Checklist.design is a free collection of UX and UI best-practice checklists covering standalone pages, individual elements, complete flows, and cross-cutting topics like responsiveness and typography.
Instead of one long best-practices article, it breaks guidance into scannable checklist items you can literally check off against a design in progress, plus linked reference articles and tools next to each topic for anyone who wants to go deeper.
Designers doing a QA pass before shipping, or anyone wanting a quick sanity check on whether a form, table, or flow is missing something obvious.
Use it as a pre-handoff checklist rather than a learning resource read start to finish. It works best pulled up next to an actual design file, checking items one at a time.
A collection of the best UX and UI practices, in checklist form.
