The Problem
Your website is losing customers you already paid for
Every day, visitors land on your site and leave. Slow, confusing, forgettable — traffic you paid for, walking straight out the door.

Trusted by clients worldwide
MDX understood our brand before we even finished explaining it. They turned EATnaked into a site that feels as clean and honest as the product itself — fast, beautiful, and effortless to navigate. Working with them felt less like hiring an agency and more like adding a team that actually cared.
We needed a site that made us look as solid as the work we do, and MDX delivered exactly that. The whole process was smooth, professional, and on time. Our new website finally matches the quality of our service — clients notice the difference the moment they land on it.
The level of craft MDX brought to Prevvi was on another level. They didn't just build what we asked for — they pushed the design further than we imagined and made it feel premium end to end. Genuinely impressed with the attention to detail and how easy they were to work with.
MDX took a complex product and made it feel simple and trustworthy for our users. The design is sharp, the experience is seamless, and they hit every deadline along the way. They became a real extension of our team — exactly the kind of partner you want when the details matter.
FAQs
What You're Probably Wondering
01 How much does custom web development cost?
Every site is scoped to your goals, so pricing is custom. Most projects start in the low-to-mid four figures and scale with complexity — you get an exact quote after a quick call, and a high-converting site usually pays for itself in new business within months.
02 How long does it take to build a custom website?
A focused marketing site goes live in a few weeks. Larger sites and web apps with custom functionality take longer. We work in stages with previews along the way, so you see progress early and there are no surprises at launch.
03 What technologies do you build with?
Modern, fast, SEO-friendly stacks — Astro, Next.js, React, and headless CMS setups like WordPress or Sanity. We pick the tools that fit your goals, not whatever's trendy, so the site stays fast and easy to maintain.
04 Do I own the website and code?
Yes. Everything we build is yours — full code, design files, and accounts. There's no lock-in and no proprietary platform holding your site hostage. You can host it anywhere and bring in any developer later.
05 What is custom web development?
Custom web development means building a website from scratch around your brand, goals, and users — instead of forcing a generic template to fit. You get a faster, better-converting, fully tailored site that does exactly what your business needs.
06 Will my site be fast and good for SEO?
Yes. We build for Core Web Vitals from the start — clean code, optimized images, and proper structure — so your site loads fast and gives Google every reason to rank it. Performance and SEO aren't add-ons; they're baked in.
07 Do you offer support after launch?
Yes. We don't disappear at launch. We offer ongoing support, maintenance, and improvements so your site keeps performing, stays secure, and evolves as your business grows.
