UI Pixels is a fully free design-resource gallery: PSD, Sketch, Figma, and Adobe XD files across UI kits, app and website templates, mockups, and icons, with over 1.9 million downloads.
Everything here is free with no premium tier to hit a paywall on, which isn't true of several other aggregators in this category that gate their better resources.
Good default choice when you specifically want to avoid a freemium bait-and-switch and just need a genuinely free UI kit or template.
All-free usually means less depth and fewer premium/newer resources than a marketplace with paid tiers: expect a smaller, older-skewing catalog in exchange for zero cost.
A gallery of free PSD and Sketch resources you can download and use freely.
