When a business owner in Scotland asks me to build them an AI app, the first thing I tell them is this: the technology stack matters more than most people think. Not because one set of tools is inherently superior, but because the wrong combination will slow you down, cost you more, and produce something brittle that breaks the moment a real user touches it.
I've settled on a specific stack after building across several Scottish businesses — from hospitality venues in Ayrshire to service-based operations that needed intelligent automation built around their actual workflows. As an AI app developer Scotland businesses come to when they want something that actually ships, here's what I use and why.
React, Supabase and Netlify — The Core Three
Every app I build runs on the same foundation. React handles the front end — it's fast, component-based, and lets me build interfaces that feel like proper software rather than a bolted-together website. Supabase sits underneath as the database and backend, giving me real-time data, authentication and edge functions without the overhead of managing a server. Netlify handles deployment and hosting, including serverless functions that talk to external APIs.
Together these three mean I can move quickly. A project that might take months in a traditional agency environment can be in front of real users within weeks. That's not a pitch — it's just what a focused stack does when you know it well.
- React — fast, composable UI that scales as the app grows
- Supabase — managed Postgres with auth, storage and edge functions built in
- Netlify — deployment, hosting and serverless functions in one place
- Claude API — the AI layer that handles reasoning, generation and intelligent responses
Where Claude Comes In
The Claude API is what turns a functional app into an intelligent one. I use it for everything from summarising incoming client data to generating structured outputs based on business logic. In a recent project — a custom briefing tool for a hospitality client — Claude processes live information and surfaces what the team actually needs to know, rather than dumping raw data on them and expecting humans to do the filtering.
That's the difference between bolting AI onto something and genuinely integrating it. As an AI app developer Scotland focused on practical results, I'm not interested in AI features that look impressive in a demo and disappear in production. Claude is reliable enough, and the API is straightforward enough, that I can build around it with confidence.
Why This Stack Suits Scottish Businesses Specifically
Most Scottish businesses I work with aren't enterprise-scale. They don't need a team of ten developers and a six-month discovery phase. They need something that works, that integrates with how they already operate, and that doesn't fall apart when the developer leaves the room.
This stack is maintainable. The codebase is clean, the services are well-documented, and if a business grows or changes direction, the app can grow with it. That's what responsible development looks like — not the shiniest possible solution, but the right one.
