Marketing Websites
High-converting sites built for SEO, speed, and lead generation. CMS-driven so your team can update content without a developer.
Service
Websites that Load Fast, Rank, and Convert.
Modern web development on Next.js, React, and headless CMS. Marketing sites built for SEO and speed, SaaS dashboards built for product velocity, and e-commerce stores built for revenue.
What is it?
Web Development, defined
Web Development at Magnis AI is the design, build, and launch of websites and web applications using a modern stack (Next.js, React, TypeScript, headless CMS, and serverless infrastructure). Sites are engineered for Core Web Vitals, search indexability, accessibility, and conversion rate, not just visual delivery.
Who needs this?
You probably need this if any of these sound familiar
- SMBs and startups whose current site is slow, hard to update, or built on outdated tech
- Founders launching a new product and needing a marketing site that converts
- Companies migrating from WordPress, Wix, or Squarespace to a faster stack
- Businesses that need a custom web app: dashboards, portals, calculators, configurators
- E-commerce stores needing a headless rebuild for speed and flexibility
Overview
Web Development, the practice in summary
A website is a sales asset, not a brochure. Magnis AI builds sites that load in under a second, rank in Google, and turn traffic into leads or revenue. The stack we choose (Next.js, headless CMS, Vercel or similar) is the same stack used by Notion, Loom, GitHub, and Linear, because it actually performs.
Capabilities
What we deliver
Each capability is a defined deliverable with clear inputs, outputs, and review gates.
SaaS Marketing Sites
Multi-page sites with feature pages, pricing, docs, blog, and a clear path from visitor to signup. Engineered for product-led growth motion.
Custom Web Apps
Customer portals, internal dashboards, calculators, configurators, booking systems, and dashboards. Built on Next.js, React, and the right database for your scale.
Headless E-commerce
Shopify, BigCommerce, Medusa, or Commerce.js on a headless front-end. Massive speed gains over legacy themes, with full design freedom.
Migrations to Modern Stack

Conversion Rate Optimisation
Heatmaps, A/B tests, CRO audits, and structural redesigns that lift form fills, signups, and revenue from existing traffic.
Framework
The Magnis Conversion-First Build Method
Every site we build is scored on five axes before launch: Speed (Core Web Vitals pass on mobile), SEO (technical fundamentals + on-page), Accessibility (WCAG AA), Conversion (clear CTA per section, measurable funnel), and Maintainability (your team can update it without a developer). We do not ship if any axis fails.

Common questions about Web Development
Why Next.js instead of WordPress?
Next.js is faster (sub-second load times), more secure (no PHP exploits or plugin chaos), more flexible (no theme constraints), and ranks better (better Core Web Vitals). WordPress still works for blog-heavy editorial sites, but for marketing sites and apps, Next.js is the modern default.
Can we update content ourselves after launch?
Yes. We pair Next.js with a headless CMS (Sanity, Contentful, Strapi, Payload, or similar) so your team edits content in a clean editor without touching code. Publishing is one click and the change goes live within seconds.
Will we lose our SEO if we redesign?
Not if it is done right. Magnis AI handles URL mapping, 301 redirects from old URLs, schema preservation, and content parity. Most clients see SEO improve after migration because the new site is faster and more crawlable.
Do you do e-commerce, and which platform?
Yes. We build headless e-commerce on Shopify (most common), BigCommerce, Medusa (open source), or Commerce.js. The front-end is Next.js, which is significantly faster than a Shopify theme. This is the same approach Allbirds, Gymshark, and Glossier use.
How long does a typical project take and what does it cost?
Marketing sites: 6 to 10 weeks. SaaS marketing sites: 8 to 12 weeks. Custom web apps: 12 to 24 weeks depending on scope. E-commerce headless rebuilds: 10 to 16 weeks. We quote after a 30-minute scoping call.
Do you handle hosting and ongoing maintenance?
Hosting yes, on Vercel, Netlify, or AWS depending on your needs. Ongoing maintenance is a separate service under Website Maintenance (see /services/website-maintenance). We do not lock you into Magnis as your hosting provider.
