Glassmorphism Generator — backdrop-filter + Tailwind + SwiftUI

Real-world use cases

• Match an iOS app's settings page on the web marketing site

  Your iOS app's settings screen uses `.regularMaterial` rounded cards. The web team is shipping a marketing page that needs to feel like the same app. Pick the Apple Glass preset, switch the export tab to CSS, paste into the marketing site's component styles. The blur radius / saturation / border opacity / shadow all line up with what `.regularMaterial` renders on iOS — same visual weight, no "the web version looks plasticky" feedback in design review.

• Build a glassy Discord-style mini-app overlay

  You're prototyping a floating widget that sits over a vibrant server background. Use the Liquid Cyan preset, pick the Aurora background to test against the most punishing case (lots of competing colour), bump the border alpha to 0.4 so the rim stays visible, copy the Tailwind classes into your React component. Done in two minutes; no Photoshop, no asset export, no PNG that will look wrong on a different gradient.

• Stand up a SwiftUI control center clone for a demo

  You're showing a hackathon teammate how SwiftUI Material works. Pick the iOS Control Centre preset, switch the export tab to SwiftUI, paste the snippet. They get a `RoundedRectangle() .fill(.regularMaterial).overlay(...)` block that compiles and renders the rounded glass panel out of the box — much faster than reading Apple docs and assembling the modifiers from scratch.

• Test glass legibility against a sunset photo before committing

  You found a hero photo with warm orange-pink tones. Before you design the card on top of it, pick the Mountain background (a stand-in for sunset gradients) and tune tint / alpha until your title text stays readable. Now you know: white tint at 18% alpha works, 8% alpha turns the title into a ghost. Adjust before you finalise the photo crop, not after.

• Audit existing glass cards across your design system

  You inherited a Figma file with 11 glass cards, each tuned by a different designer. Paste each card's CSS into the generator's URL state (mirror the values via the sliders), screenshot the preview, lay them out side by side. The inconsistencies pop immediately — three different blur radii for cards that should match, two opacity tiers that drift by 5%. Easier to argue for consolidation with the proof in hand.

• Ship a glass call-to-action button that survives dark mode

  Your CTA button is white-tinted glass. In dark mode the white tint reads as overly bright; you want the same component to work in both. Use the Dark Glass preset to see how an inverted tint feels in dark mode, copy two variants of the Tailwind string, drive them with your dark-mode media query. One component, two themes, both rendered correctly.

Common pitfalls

• Forgetting the -webkit-backdrop-filter prefix and watching iOS Safari 14-16 users see a flat transparent rectangle. The generator emits both lines for you; if you only copy one, copy the prefixed line.

• Designing the glass card over a pure-white background, then being surprised "the blur effect is invisible". There is nothing behind to blur. Either add texture / a gradient to the background, or lean on border + shadow to define the card edge.

• Cranking blur past 24 px and saturate past 180 % at the same time — iOS Safari can drop frames on the resulting overdraw. Pick one of the two as your dominant axis (heavy blur OR heavy saturate) for buttery scrolling on older iPhones.

• Using `bg-[rgba(...)]` Tailwind classes in a project pinned to Tailwind 2.x without JIT. Arbitrary-value classes require JIT (default since 3.0). Upgrade Tailwind, or move the rgba() into your colors config.

• Picking `.ultraThickMaterial` in SwiftUI when the web blur was 8 px. The material levels are coarser than CSS blur — use the mapping the generator outputs, do not pick the nearest-sounding material name by ear.
