Web Development Leeds

Leodis Digital is a web development company in Leeds that builds modern, high-performance websites, web applications, and custom business software. We use frameworks like Vite, Astro, and Preact to create fast, practical systems — from marketing sites to invoicing software and lightweight SaaS-style platforms.

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 (Google/DCLK, 2016). Every 100ms improvement in load time increases conversion rates by up to 8% (Deloitte/Google, 2020). 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 invoicing systems, booking workflows, client portals, dashboard interfaces, internal tools, and lightweight SaaS-style platforms.

The best projects usually start with a messy operational problem: too many spreadsheets, duplicated admin, manual chasing, or a process that only one person understands. We turn that workflow into a focused web app that staff can actually use.

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

Invoicing Software and Internal Tools

We have already built and delivered invoicing software, so this is not a speculative service. If your business needs quoting, invoice tracking, payment status, customer records, reporting, reminders, or role-based admin workflows, we can design and build a system around how your team already works.

We are careful with scope. Not every business needs a full SaaS product. Sometimes the right answer is a small internal tool that saves hours every week. If you do need a customer-facing platform, we can build that too — with authentication, dashboards, email flows, and the SEO foundations needed for any public pages.

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.
