Ensure your website is built the right way. Don’t risk costly rebuilds, difficult site admin, future bug fixes and breakages, insecure data or poor performance.

We develop future proof, robust, cleanly coded, upgradable websites built to evolve with your business. Here at Mainstay Digital we have an ethos and core company value of doing what we do very well.




Built for longevity

Our websites and applications are built for the long term. This means that although the digital landscape may be evolving rapidly, our products have the robust architecture, in-built flexibility, scalability and best practice code to evolve as your business does.

We have a firm conviction that you should not be having to rebuild every 1 – 2 years – your digital platform should have been built as future-proofed as possible, and that new features, layouts, designs, campaigns or upgrades be needed, it’s straightforward, and that your investment continues to see years of return.

Best coding and web development practices

Time and again we encounter legacy websites and systems which were badly, inefficiently, or lazily implemented. Spaghetti-code situations with cross dependencies which make upgrades next to impossible.

Our development takes a best-practice approach, with a focus on clean, logical, documented code. Our tight-knit local team ensures continual quality, with tried and tested open-source tech stacks.

We love lean, intuitive, intelligent systems! This means for future, upgrades and scalability is enhanced, whilst risk and cost is reduced.

Ease of management and administration

Whether you’re building in WordPress, Craft, or a custom React or Laravel application, we bring together simplicity, intuition and flexibility to ongoing management for your web team. We’ll configure administration and management of content, articles, users, transactions or products to whatever level of granular management is required – and give you training if you need it.

“The team at Mainstay have been a massive support to the Live for Lily Foundation, in the design and roll out of our new website, the implementation of an improved email server, and general all round assistance of all our information technology needs. They’re responsive to our requests and service is second to none in ensuring our requirements are met and the performance of our site is optimal and secure.”

Philip Martins - Director and Chief Financial Officer, Live for Lily Foundation


Big or small, we strive to build awesome relationships with our clients. Here’s a handful that we’ve had the privilege of working with.


We offer 12 month warranty on projects, as well as a money back guarantee period to prove our ability, give you peace of mind, and zero risk.


End-to-end projects

We’re there from idea inception through to launch, helping you gather requirements, scope features, design & UX, building, testing, launch and training and support.

New features & functionality

Perhaps just your homepage and navigation needs a refresh, or you have a backlog of ideas to implement. We’ll help you plan, prioritise, execute and measure over the long term.

Systems integration

Integrating and automating business operations means greater efficiencies and productivity. Bring together your siloed systems for seamless data flow.

Legacy issues & refactoring

Old, archaic or poorly built websites can be a business’s Achilles heal. That doesn’t mean old projects need to thrown out – sometimes it just means rebuilding to modern code standards.

Headless WordPress

For custom builds, especially where multiple content platforms are involved, Headless WordPress with a React front end can mean powerful scalability.

Website Performance

Traffic retention, SEO and great UX all need a fast and responsive site. We’ll optimise it to the nth degree to ensure it’s performing to potential.

We design and build digital products of all shapes and sizes. Website and application development often requires a flexible approach to the process.

Some phases may be linear, some may run concurrently, or the project may call for an Agile approach.

Each project is unique, and so are our relationships.

Depending on your organisational or project needs, projects may be managed in a variety of forms – fixed price/scope, agile/sprint based, dedicated resources, or time and materials.

We work with our clients and strategic partners to create beautiful user experiences; robust, functional and practical products, and achieve positive, meaningful outcomes.
