Templates and screens
Pages and app screens built from your designs in your framework, or in plain HTML and CSS.
The Problem
Your Front End Was Built by Whoever Had Time
It shows up once the product has real users. Screens load slowly on phones, keyboard users get stuck, and every small UI change breaks something in another browser.
01 · Weight
Screens ship heavy JavaScript before anything appears.
We split bundles by route and load scripts only where they're needed.
02 · Access
Styled divs act as buttons that keyboards can't reach.
We use semantic HTML and test every flow with a keyboard.
03 · Browsers
Layouts break in Safari or Firefox after each release.
Every release is tested in Chrome, Safari, Firefox, and Edge.
04 · Styles
Each new screen copies styles from the last one.
Shared components and design tokens replace copied CSS across the app.
Your back-end developers built the interface between other tasks, and it shows. The dashboard ships 2 MB of JavaScript before anything appears. Buttons are styled divs that a keyboard can't reach. Safari renders the date picker differently, and nobody tested Firefox at all. Each new screen copies CSS from the last one, so a color change means editing forty files. UI tickets keep coming, and your developers would rather be fixing the API.
We start by measuring: Core Web Vitals on real pages, an accessibility scan plus keyboard checks, and a list of browser bugs. Then we set a budget for each template and build or rebuild the interface to meet it, in the framework you already use. Shared components and design tokens replace copied CSS. Your back-end team gets their time back, and the UI stops generating tickets.
Budgets per template
Load, interaction, and layout-shift targets are set per template and checked on every release.
Keyboard and screen reader ready
Semantic HTML first, so forms and menus work for everyone without patches later.
Tested where users are
Chrome, Safari, Firefox, and Edge on desktop and phones, before anything goes live.
Our Front End Development Services Process
From UI Review to Launch in Five Clear Steps
You agree the speed and accessibility targets before we build, then review every screen on a preview link on your own phone.
We measure Core Web Vitals on your key pages, run an accessibility scan with keyboard checks, and test the main flows in four browsers. You get the issue list, the budgets we'd set, and the plan that fits.
What's Included
What You Get From a Front End Development Company
A front end your team can keep fast: interface code in your stack, components and tokens, budgets, accessibility and browser testing, and documentation for the next developer.

What Our Clients Say
What Clients Say After Launch
Feedback from teams we have built websites and app interfaces for.
We had a pretty specific idea of what we wanted our website to become, but I wasn’t sure how easily we could explain all of it to a development team. There were quite a few moving parts, and we were working toward a deadline, so I expected a few things to get lost along the way. That never really happened. They understood what we were trying to achieve, kept us updated throughout the process, and got everything ready within the agreed timeline. The final site feels much easier to navigate, works beautifully on mobile, and is noticeably smoother for our customers. It was a huge relief seeing the original idea actually turn into the website we had in mind.
The mobile experience is probably my favourite part of the new site. We had spent a lot of time making sure the desktop version looked right, and the team kept pushing us to think about how everything would actually feel on a phone too. They were right. The navigation is clean, the interactions feel natural, and everything we’ve tested so far works exactly as it should. They also went through the links, forms, integrations, and other details more than once before launch, which I really appreciated. And even after going live, we could still reach out when something came up. The whole process felt friendly, organised, and surprisingly straightforward.
What I appreciate most is that the website is actually easy for us to manage now. We can update content ourselves instead of sending a developer a message every time we need to change something small. They also paid attention to the technical SEO side, which mattered to us because we didn’t want a new website to create problems for the traffic we already had. I’ve probably asked more questions than I should have since launch, but every question has been handled patiently and without any fuss. The team is easy to work with, they explain things clearly, and when we need something changed, they focus on getting it done rather than making the process complicated.

Work Culture
Why Product Teams Pick Us as Their Frontend Development Company
Front ends decay quietly: one copied style, one skipped browser, one unlabeled button at a time. These habits stop that drift.
Budgets, not opinions
We agree measurable targets for speed and accessibility before building. Debates about whether a screen feels fast end when the numbers are on the dashboard.
HTML before JavaScript
We reach for semantic HTML and CSS first and add JavaScript only where interaction needs it. Pages get lighter, and more of them work without extra scripts.
Your framework, not ours
We work in React, Vue, Angular, Svelte, or plain templates, whatever your team already runs. You won't inherit a second stack to maintain.
Honest about rebuilds
If fixing your current front end costs less than rebuilding it, that's what we recommend. If a theme or template covers your needs, we'll tell you before we quote.
Visual tests on every change
Screenshots of key screens are compared automatically on each pull request. Layout slips get caught in review instead of by your customers.
Everything stays in your name
The repository, hosting, and design files stay in your accounts from day one. You can bring the front end in-house whenever you choose.

Good fit
Back-end teams without a UI specialist
Your developers are strong on APIs and databases, and the interface shows it: slow screens, odd spacing, and forms that confuse users.
SaaS teams with a large single-page app
Your single-page app grew to dozens of screens, and you need frontend development services that bring speed and consistency back.
Companies facing an accessibility deadline
You've received an accessibility complaint or a procurement checklist, and your interface needs keyboard support and proper labels fast.
Marketing teams with slow sites
Your marketing site scores poorly on Core Web Vitals, and you want front end web development services that fix templates, not just images.
Agencies needing front-end capacity
You've designed a client site or app and need a front end web development company to build it to your standard under your brand.
Not a fit
Full React app build
You need a complete React app with server rendering and a shared component library. React Development Services is set up for exactly that scope.
No designs yet
You don't have designs and need the interface planned first. UI/UX Design Services plans the screens, and we can build them afterwards.
Budget under $1,000
You need one CSS fix or a small tweak to a template. A freelancer or your theme's support team will cost less than our smallest plan.
Only page speed is wrong
Your front end works well, and only Core Web Vitals need fixing. Core Web Vitals Optimization targets that directly at a lower cost.

Freelance front end developer rates vary widely by country, seniority, and framework, so compare scoped quotes instead of hourly rates. Our fixed-price work starts at $1,000 for a fix sprint, $3,600 for a build of up to 12 templates, and $7,400 for a complex single-page app. If one freelancer fits a small task, that's often cheaper.
Most front end projects take 1 to 2 weeks for a fix sprint and 4 to 8 weeks for a site or app section. A complex single-page app takes 6 to 14 weeks. API readiness and design changes affect the timeline most. You review each screen on a preview link as soon as it's finished.
Front-end development is building everything a visitor sees and touches in the browser: layout, text, forms, menus, and animations. It uses HTML for structure, CSS for styling, and JavaScript or TypeScript for behavior. Good front-end work also covers speed, accessibility, and how pages behave on different devices.
Front end website development is the browser-side build of a website: turning designs into responsive pages that load quickly and work with a keyboard. For a marketing site, that means templates, navigation, forms, and content blocks. The back end, such as a CMS or database, supplies the content those templates display.
In web development, the front end is the layer that runs in the visitor's browser, while the back end runs on a server. The front end requests data through APIs and turns it into screens people can use. Many bugs users notice, like slow pages or broken forms, live in the front end.
A front end developer turns designs into working interfaces and keeps them fast, accessible, and consistent. Day to day, that means building components, connecting them to APIs, fixing browser bugs, and testing on phones. Senior front end developers also set performance budgets and push back on designs that would hurt usability.
The best outsourcing provider for a complex SPA is one that proves its work with numbers in your framework. Ask for performance budgets, accessibility test results, and a sample of component docs, and check how they handle state and API errors. We fit teams that want fixed scopes and measured targets; a large consultancy suits programs needing dozens of developers.
Hire a front end developer by testing what users will feel: speed, accessibility, and browser coverage. Give candidates a small paid task built from one of your designs, then check it with a keyboard, in Safari, and in Lighthouse. Review their CSS structure too, because messy styles get expensive within months.
Yes, we work in React, Vue, Angular, Svelte, or plain HTML and CSS, whichever your app already uses. We don't push a rewrite into a new framework unless the current one blocks your goals. For simple marketing pages, plain templates with a little TypeScript often load faster than a heavy framework.
After launch, we compare real-user Core Web Vitals with the budgets and fix anything that misses. You get component docs, the test setup, and a recorded walkthrough of the code. Support runs 30 to 90 days depending on your plan, and your team can keep the budget checks running in CI.
