FAQ
Common questions
For performance, SEO, and scalability, Next.js or Remix with a headless CMS (Contentful, Sanity) dramatically outperforms WordPress. WordPress is viable for simple blogs, but modern React stacks give you better Core Web Vitals, tighter security, and unlimited scalability for SaaS, enterprise, or high-traffic marketing sites.
SEO is built into our development process — not bolted on after. We handle server-side rendering for crawlability, structured data schemas, meta tag management, sitemap generation, canonical URLs, page speed optimization, and Core Web Vitals from day one.
A marketing website or landing page takes 4–8 weeks. A full web application with authentication, dashboards, and integrations takes 12–24 weeks. We always deliver functional milestones on bi-weekly sprint boundaries.
Yes — WCAG 2.1 AA accessibility is a standard deliverable, not an add-on. We use semantic HTML, ARIA roles, keyboard navigation, skip links, focus management, and automated axe-core testing in our CI pipeline.
