Common questions.

Still unsure? We'd rather answer than have you guess.

Book 30-min strategy call

Who owns the code and domain?

You do. Repo transferred to your GitHub at launch. Domain always yours. We don't hold anything hostage — leave anytime, keep everything.

Can I edit the site after launch?

Content via CMS (if included) needs zero dev work. Structural changes need dev — you can hire us on retainer ($800/mo) or any Next.js dev, because the codebase is standard.

What if I already have a designer?

We can build from your Figma. 15% discount on the design portion. Dev timelines stay the same — handoff should include components, tokens, and states documented.

Do you do WordPress / Webflow / Wix?

No. We build on Next.js because it's faster, more secure, better for SEO, and cheaper to host long-term. If you specifically need WordPress, we'll point you to someone great.

What about hosting and domains?

Cloudflare Pages included free for the first 12 months. After that, $0–$25/mo depending on traffic. Domain transfer or setup handled at cost — no markup.

Can you redesign my existing site?

Yes — most of our work is redesigns. Free audit first, scope second, quote third. Migration path + SEO preservation + 301 redirects all handled so you don't lose rankings.
