Custom websites and web apps built to convert and compound.

From conversion-focused marketing sites to full-stack web applications, MerryMango delivers modern, production-grade builds on Next.js and React — senior-led, fixed-fee, no surprises.

Starting from $2,500 · Typical projects: $5,000 – $25,000 · Timeline: 3–10 weeks

Your website is your highest-leverage sales asset.

Performance that pays off

A one-second delay in page load time reduces conversions by up to 7%. We target Lighthouse scores above 95 on every project — not as a vanity metric, but because speed directly affects revenue and Google ranking.

🔒

Built to last, not to break

Most agencies deliver sites that need a full rebuild within two years. We build on a stable, modern stack with clean architecture and thorough documentation so your team can maintain and extend it without us.

📈

Engineered for conversion

Beautiful is table stakes. Every layout decision, copy hierarchy, and CTA placement in our builds is informed by conversion principles — so your site doesn't just look credible, it turns visitors into leads.

Four types of web projects we do well.

01 · Marketing Sites

Conversion-focused brand sites

For founders, SaaS products, and professional services firms that need a site that actively generates inbound leads. Clean architecture, fast load times, and copy-first design. Integrates with your CRM, analytics, and booking stack.

02 · Web Applications

Full-stack product builds

Custom web applications with authentication, databases, APIs, and dashboards. Built on Next.js App Router with TypeScript. Suitable for internal tools, client portals, SaaS MVPs, and complex data-driven interfaces.

03 · Platform Migrations

WordPress replacements & rebuilds

Legacy CMS on your back? We migrate WordPress, Wix, and Webflow sites to a modern stack — keeping your content, SEO equity, and URLs intact while dramatically improving performance and developer experience.

04 · E-commerce

Shopify and headless storefronts

Custom Shopify themes and headless e-commerce builds using Next.js and Shopify's Storefront API. Ideal for brands that have outgrown templates and want a storefront that matches their product quality.

Common questions about our web work.

Something else? Email us directly.

Do you do design or just development?
Both. Most of our engagements include UI/UX design in Figma before development begins. If you have an existing design system or brand guidelines, we build to those. We can also work with your in-house designer if you prefer to separate the disciplines.
What if I need changes after launch?
All projects ship with a two-week post-launch bug fix window at no charge. For ongoing changes and development, we offer monthly care plans or can prepare a separate scope. We don't lock you into a long-term contract.
Will I be able to update the site myself?
Yes. If you want content editing control, we integrate a headless CMS (typically Sanity or Contentful) so non-developers on your team can update text, images, and structured content without touching code. We record a walkthrough video so you know exactly how.
How is this different from a WordPress agency?
We build on a modern JavaScript stack (Next.js) rather than WordPress. That means dramatically faster page loads, better security posture, no plugin bloat, and a codebase your developers can actually work with. The tradeoff is that content editing requires a CMS setup — which we handle as part of the project.
Do you offer hosting?
We deploy to Vercel, Cloudflare Pages, or AWS depending on your requirements. These run in your own account — you own the infrastructure. We can handle the initial setup and ongoing DevOps as part of a care plan, or hand it over to your team with documentation.
