Social Platform Design Systems
Design at scale. Billions of users. These are the systems that held up.
Social platforms operate at an insane scale and their design systems reflect that. These DESIGN.md files capture the design language of the platforms where people spend hours a day — Discord's dark playfulness, Meta's confident blue, Pinterest's visual richness. They work as starting points for any community or social feature you are building.

3 Social design systems
Discord
A community communication platform built around the iconic blurple (#5865F2) on a dark three-tone surface system — deep background (#313338), elevated panels (#2B2D31), and the darkest modals (#1E1F22). The UI reads as game-adjacent without being garish: rounded shapes, expressive emoji reactions, status indicators in four meaningful colors, and a sidebar that holds entire community architectures. Typography uses GGSans (Discord's custom typeface) — a rounded geometric grotesque that's playful but still legible at chat density. Blurple appears on primary CTAs, active channel indicators, and the brand itself — a color so tied to Discord it's named in community vocabulary.
Meta
Meta's design system spans hardware commerce (Quest VR, Ray-Ban Meta AI glasses) and brand surfaces with a confident product-merchandising voice. The system pairs a stark white canvas with full-bleed photographic product cards, a confident Optimistic VF wordmark/headline face, dual-CTA hero patterns (black primary + outlined secondary), and a saturated cobalt blue (#0064E0) for in-product purchase actions. Pill-shaped 100px-radius buttons, generous 24-32px card rounding, and tight three-tier text hierarchy carry across homepage, product detail (PDP), buy-now configurator, and accessory subpages.
A photography-first discovery system organized around the Pinterest Red CTA, the masonry pin grid, and a soft warm-cream chrome that gets out of the imagery's way. The home page is a content-discovery tool wearing the chrome of a magazine publisher: 70px display headlines, friendly Pin Sans typography, fully-rounded pill buttons (16px) on a cream-tinted neutral palette, and a sticky red "Sign up" CTA that anchors every viewport. Pin imagery is the system's load-bearing visual element — square, portrait, and landscape pins tile in a column-based masonry grid where each tile is a fully-rounded 16px-radius card, separated by tight 8px gutters. The chrome is otherwise quiet: warm grays, true whites, and a single saturated red — no decorative gradients, no atmospheric backgrounds, no shadows beyond a soft modal scrim.
