FAQ
Answers before you ask.
What stack do you build on?+
Defaults: TypeScript + React (Next.js / TanStack Start), Tailwind, a headless CMS, hosted on Vercel or Cloudflare. We adapt to your stack when it makes sense.
Will we own the code?+
Always. You own the repository, designs, hosting accounts and CMS — no platform lock-in.
Can you replatform from WordPress / Webflow?+
Yes. We handle URL mapping, redirects and SEO preservation so traffic doesn't drop after the cutover.
Do you offer ongoing support?+
Yes — most clients move into a small growth retainer post-launch for ongoing optimization and feature work.
