Web and software development

Websites, web apps and custom software, built to last

Avernixx is an established web and software development firm that now also delivers AI. We design, build and support websites, web applications, custom software and the integrations that connect your systems, with security and data protection built in from the start.

Let's talk See what we build

What we build

Four kinds of work, one team

Websites

Fast, multilingual company websites that are easy to update, easy to find on search and AI answer engines, and ready for enquiries and bookings.

Web applications and portals

Customer and partner portals, booking and ordering flows, dashboards and internal tools that run in the browser.

Custom software

Software shaped around the way your business actually works, when off-the-shelf tools force too many workarounds.

Integrations and APIs

Connecting your CRM, accounting, e-commerce, messaging and in-house systems, so data moves without copy and paste.

Where it genuinely helps, we add AI features such as assistants, search and document processing, governed from day one.

How we work

From first conversation to launch, and after

Discover

We learn your goals, users, systems and constraints, and agree what success looks like.

Design

User journeys and screens you can click through before any build starts.

Build

Short, visible iterations with regular demonstrations, so you see progress throughout.

Test and launch

Functional, security, speed and phone-width testing, then a planned go-live.

Support

Fixes, updates and improvements after launch, on terms agreed in advance.

Frequently Asked Questions

Yes. We can improve, extend or integrate with what you already have, or recommend a rebuild when that is the better value. We tell you which, and why.

Ownership and handover terms are agreed in writing before work starts, so you know exactly what you will receive.

No. We add AI features only where they clearly help, such as an assistant that answers questions from your own content, and we build them with governance and data protection in mind.

Each project is scoped first. Scope and fees are agreed in writing before work begins. See How We Price for the details.
