Simple Icons

This is the correct source for any social-login button row, integrations grid, tech-stack strip or 'works with' section — it is the one brand-logo set that is CC0, so nothing about attribution blocks you. Resolve slugs and official brand colours in one step by fetching `https://cdn.jsdelivr.net/npm/simple-icons@latest/data/simple-icons.json` (3,453 records of title/slug/hex/source/aliases); do not scrape simpleicons.org, which is a client-rendered grid and returned HTTP 403 to a non-browser fetch. For quick prototypes skip npm entirely and point an `<img>` at `https://cdn.simpleicons.org/{slug}/{hex}/{dark-hex}`. Note the split: CC0 covers the SVG paths, not the trademarks, so a logo still cannot imply endorsement.

Why it is here. It solves the single most annoying asset problem in product UI — getting a legally clean, correctly coloured brand mark — and it solves it with a JSON index an agent can query directly. Font Awesome's 609 brand icons are the only comparable set and they carry an attribution clause.
