Web Development Leeds

Leodis Digital is a web development company in Leeds that builds modern, high-performance websites and web applications. We use frameworks like Vite, Astro, and Preact to create sites that are genuinely fast — not just "fast enough" but consistently scoring 90+ on Google PageSpeed Insights.

Why Performance-First Development Matters

Google has made Core Web Vitals a ranking signal. Your website's load time, interactivity, and visual stability directly affect where you appear in search results. For Leeds businesses competing in local search, this is not theoretical — a slow website loses rankings to faster competitors.

The numbers are clear: 53% of mobile visitors leave a page that takes longer than 3 seconds to load. Every 100ms improvement in load time increases conversion rates by up to 8%. For a local business getting 1,000 visitors a month, that performance gap translates directly into lost enquiries and revenue.

We build websites that load in under a second. Not because we add a caching plugin to a bloated template, but because we use modern frameworks that generate minimal, optimised code from the start.

Our Technology Stack

We build on modern JavaScript frameworks that produce static or hybrid sites with exceptional performance:

**Vite** — Our primary build tool. Instant hot module replacement during development, optimised production builds with code splitting, tree shaking, and asset hashing.

**Astro** — For content-heavy sites that need excellent SEO. Astro ships zero JavaScript by default and hydrates interactive components on demand. Perfect for blogs, portfolios, and marketing sites.

**Preact** — A 3KB alternative to React that delivers the same developer experience with a fraction of the bundle size. Ideal for interactive applications where performance is critical.

We do not use WordPress, Wix, or Squarespace. These platforms add layers of abstraction, unnecessary JavaScript, and database queries that slow your site down. Our approach starts fast and stays fast.

Custom Web Applications

Beyond marketing websites, we build custom web applications for Leeds businesses that need more than a brochure site. This includes booking systems, client portals, dashboard interfaces, and internal tools.

Our web applications are built with the same performance-first approach: server-side rendering where it matters, edge deployment via Cloudflare Workers for low latency, and API architectures that scale with your business.

Recent examples include Nat20 Labs — a high-performance platform for a TTRPG and cryptographic dice project that needed to handle real-time interactions while maintaining perfect PageSpeed scores.

Ongoing Maintenance and Support

A website is not a one-off project. Dependencies need updating, security patches need applying, SSL certificates need renewing, and content needs refreshing. Neglected websites become slow, insecure, and invisible to search engines.

Our pay-monthly model includes all of this. We monitor your site's performance continuously, apply updates proactively, and fix issues before they affect your visitors or your rankings. You get a technical team looking after your website for a predictable monthly cost.

For businesses on our higher-tier plans, maintenance includes active SEO management — ensuring that your website does not just stay functional but actively improves its search visibility over time.

Deployment and Infrastructure

We deploy to Cloudflare's global edge network. Your website is served from the nearest data centre to each visitor, with automatic SSL, DDoS protection, and 99.99% uptime. For Leeds visitors, that means your site loads from a UK edge node in milliseconds.

We use CI/CD pipelines (GitHub Actions) for automated builds and deployments. Every code change is tested, built, and deployed automatically — no manual uploads, no FTP, no chance of human error breaking your live site.

This infrastructure is included in every plan. You do not need to manage hosting, worry about server configuration, or deal with downtime. We handle all of it.
