High-Performance Websites & Web Applications

We build fast, accessible websites and web applications on Next.js and React, with technical SEO and Core Web Vitals engineered in, and connected to the systems your business already runs.

Common challenges

Where websites hold businesses back

Most teams come to us when a site built by a freelancer, agency or website builder stops keeping up.

  • Slow, underperforming sites

    Poor performance and search visibility cost you traffic and conversions, and are hard to fix on a fragile codebase.

  • Hard-to-maintain code

    Every change is slow and risky, so the site falls further behind what the business needs.

  • Disconnected from your systems

    The website sits apart from your internal tools and business systems, so data is re-entered by hand.

  • Accessibility and SEO gaps

    Missed accessibility and technical SEO basics limit reach and create compliance risk.

How Siprea helps

Engineered, not just designed

We are engineers, not a marketing agency or a freelancer reskinning a template. We build websites and web applications on a clean, type-safe Next.js and React stack, with performance, accessibility and technical SEO designed in from the first commit rather than bolted on later.

We also treat your website as part of your wider system. We connect it to the internal tools, content workflows and business systems you already run, so the front end and the back office work together.

  • Next.js and React applications
  • Core Web Vitals and technical SEO built in
  • Accessible by default (WCAG)
  • Integrated with your business systems

When a Website Becomes a Business Platform

Plenty of businesses outgrow the brochure website. When customers need to log in, book or transact, and when the site needs to talk to your other systems, you are no longer building a website. You are building a platform.

  • Customer portals

    Secure areas where customers log in, manage their account and self-serve.

  • Booking journeys

    Multi-step booking and enquiry flows that work reliably end to end.

  • Integrated websites

    Sites connected to your CRM, internal tools and business systems.

  • Web applications

    Interactive, data-driven applications, not static brochure pages.
