React vs Laravel for UK SMEs: What Should Your Web App Be Built With?

Business owners are regularly asked to choose between React and Laravel by people who know they are not alternatives. Here is what each one is, in terms that let you ask the right questions.

Two different jobs

Laravel is a PHP framework for the back end: the part of an application that stores data, enforces rules, talks to other systems and decides who is allowed to do what. React is a JavaScript library for the front end: the part in the browser that people click on. A web application has both jobs to do. The real decision is how much of the front end needs to behave like an app rather than a set of pages.

When Laravel on its own is enough

Most business systems - portals, CRMs, booking and admin tools - are forms, lists and pages. Laravel renders those directly, with a little JavaScript for the interactive bits. It is fast to build, easy to host on ordinary UK servers, and the pool of PHP developers in the UK is large, which matters in year three when you want someone else to maintain it. For the majority of what we build under custom web app development, this is the right shape.

When you need React

When the screen has to update continuously without reloading: live dashboards, drag-and-drop planning boards, editors, anything that feels like software rather than a website. React (or a similar library) is the right tool for that layer. It adds a build step, a second skill set and more moving parts, so it should earn its place.

Both, which is the common answer

Laravel as the back end and API, React for the parts of the interface that need to be highly interactive, plain Laravel pages for the rest. This is how we build most systems with a rich front end. It keeps the complicated JavaScript confined to the screens that need it.

What the choice means for you

Hiring and maintenance

PHP and Laravel developers are plentiful across the UK at reasonable rates. React developers are plentiful but pricier. A system that uses React everywhere needs a front-end specialist for even small changes; one that uses it selectively does not.

Hosting

Laravel runs on any decent Linux host, including UK VPS providers at £30 to £150 a month. A React front end is static files and costs almost nothing to serve. Neither pushes you towards expensive infrastructure.

Cost

A React-heavy interface adds 15 to 30 percent to a build compared with server-rendered pages, because interactive screens take longer to build and test. Worth it for the screens people live in all day; not worth it for the settings page.

Longevity

Both are mature, widely used and well maintained. The risk is not the technology going away; it is an agency choosing an unusual combination that nobody else can pick up. Ask what happens if you need a different developer in three years. The answer should be "any Laravel developer" or "any React developer", not a name.

The questions to ask an agency

1. Which parts of my application need to update without a page reload? (Those are the React candidates.)
2. Why this stack for my project specifically, rather than the one you always use?
3. How many developers in the UK could maintain this after you?
4. Will the code sit in a repository I control from the start?

What about WordPress, Webflow and the rest?

They are website tools, and good ones. The confusion arises when a website tool is pushed into being an application: plugins for bookings, memberships, portals and e-commerce stacked on top of a content system. It works up to a point and then becomes fragile, slow and expensive to change, and the person who assembled the plugins is the only one who understands it. If your requirement is a marketing site with a blog, use a website tool. If it has logins, workflow and data that matters, it is an application, and Laravel-style frameworks exist precisely for that.

What about no-code and low-code?

Genuinely useful for internal tools with simple logic and a handful of users, and for prototypes that prove a process before you build it properly. The costs arrive with scale: per-user pricing, limits on logic complexity, and the fact that the application lives on someone else's platform. For anything customer-facing or core to the business, treat low-code as a prototype stage, not the destination.

Hosting and ownership, briefly

A Laravel application with a React front end runs happily on a UK virtual server at £30 to £150 a month, in an account you own. It does not need expensive cloud infrastructure until it has thousands of concurrent users. Insist on the code living in a repository you control and on hosting in your own account; the stack matters less than those two things for what happens if you change supplier. Our agency questions cover how to check.

A rule of thumb

Count the screens that need to update live without a reload. Zero or one: Laravel alone. Two to five: Laravel with React on those screens. More than that, or the whole product is one interactive workspace: React front end with a Laravel API behind it. Decide it per screen and you will not overpay for interactivity nobody uses.

Questions we get asked about stacks

Is PHP outdated? No. Modern PHP with Laravel is fast, secure and actively developed; it runs a large share of the business web. The reputation comes from old code written badly, which is true of every language.

Should we use whatever is newest? No. New frameworks have small talent pools and unpredictable futures. The point of a stack for a business system is that in five years someone can still maintain it cheaply.

Can we change later? The front end can be replaced without touching the back end if the two are separated by an API, which is one reason to structure it that way from the start. Replacing the back end is a rewrite. Choose it once, carefully.

Does it affect SEO? For a customer-facing site, yes: server-rendered pages are indexed reliably, while heavy client-side rendering needs extra work to be crawled. For an internal tool behind a login, it does not matter.

None of this requires you to learn to code. It requires you to ask why, once, and to expect an answer in plain English. The stack is a means to the outcomes in your brief, and an agency that can connect the two is the one to work with.

If an agency cannot answer the first two in plain English, the choice is being made for their convenience rather than your outcome. Choosing the stack is one of the topics in our guide to questions to ask a web development agency. If you want us to answer them for your project, send us the brief.
