    [ Why Seraphic ]

    WHY
    Seraphic for the web.

    Performance is a feature. We engineer to Core Web Vitals, technical SEO and accessibility from the first commit — not a post-launch retrofit. Marketing teams get a CMS they can edit; engineering teams get a codebase they can scale.

    • Performance budgets enforced in CI — Lighthouse 95+ as table stakes
    • Technical SEO baked in: schema, sitemaps, canonicals, semantic HTML
    • Composable architecture — headless CMS and headless commerce
    • WebGL and motion when the brand demands presence
    • Edge-first deployments on Vercel, AWS or Cloudflare
