Tailwind CSS — 209 sites
Tailwind CSS has become the default styling layer for SaaS marketing sites. Study how these teams compose consistent spacing, type and color with utility-first CSS.
Tailwind's utility-first approach — writing `flex gap-4 text-lg` directly in markup rather than naming a custom CSS class — has become the default for SaaS marketing sites mainly because it enforces consistency almost by accident: a design system's spacing scale, type sizes and color palette are defined once in config and every utility class pulls from that same constrained set, which makes it structurally harder to introduce an off-brand one-off value than it would be writing free-form CSS. The visible tell of a well-executed Tailwind site isn't the framework itself (it's invisible in the shipped output) — it's the consistency: spacing that always steps in the same increments, a type scale with a clear number of sizes rather than dozens of slightly-different ones, which is a discipline Tailwind makes easier to maintain but doesn't guarantee on its own.
Thirty SaaS websites reviewed at equal depth from screenshots we captured ourselves — what's above the fold, the one section each does unusually well, and the stack, palette and typefaces behind it. With a stated selection method, not a handpicked vibe check.
Twenty-four product landing pages read start to finish from our own screenshots — what's in the fold, where the logo strip actually sits, how the page closes, and how long each one really runs, in pixels.
We read 24 real SaaS About Us pages against the same seven-module checklist — team photos, named people, stat tiles, timelines, investor walls, hiring CTAs, manifestos — and counted what's actually there. Only one page uses a timeline.
