What are front-end development services?

Front-end development services build the client-facing layer of websites and applications: interfaces, interactions and performance, using HTML, CSS, JavaScript and frameworks like React, Next.js and Astro. Synapse Team delivers the frontend as one managed project that plugs into your backend, API or CMS with a fixed scope, price and timeline.

Ongoing support

A frontend development company, not freelancers

A frontend is a system, not a set of pages: component libraries, typed code, tests and automatic checks. We work as your frontend development company: senior engineers, a code review for every change, and interfaces that are easy to maintain and grow.

  • Component-driven architecture with a living UI kit
  • TypeScript, tests and CI/CD from the first commit
  • Accessibility and cross-browser checks built into the process
  • Pixel-perfect to your design, compared side by side

Built for your backend and API

We integrate with whatever powers your product: REST or GraphQL APIs, headless CMS, commerce platforms or custom backends. Your team keeps the server side, we make sure everything works flawlessly on screen. For app teams this usually means React development services on top of your existing API.

  • REST, GraphQL and websocket integrations
  • Headless CMS frontends: Payload, WordPress, and more
  • React development services for product teams
  • Core Web Vitals as an engineering target: Lighthouse 100

Frequently asked questions

How much do front-end development services cost?

Front end development services are priced by the number of screens and the complexity of states. Reference points from our typical projects:

  • Landing page: from $1,000 (3–5 days).
  • Corporate website: from $2,000 (1–2 weeks).
  • Store with up to 50 products: from $3,000 (3–4 weeks).
  • AI chatbot or automation: from $2,000 (1–3 weeks).

A large app or dashboard is estimated per project. Describe the project in the chat and the team sends a precise fixed-price estimate within one business day.

How long does frontend development take?

Typical AI-powered timelines for reference formats:

  • Landing page: 3–5 days.
  • Corporate website: 1–2 weeks.
  • Store with up to 50 products: 3–4 weeks.
  • AI chatbot or automation: 1–3 weeks.

App interfaces scale with screen count, and classic development takes longer. Every quote comes with a fixed deadline before we start.

Is frontend development being replaced by AI?

Routine work is, engineering is not. AI speeds up building components and tests, which is why we ship fast, but architecture, accessibility, speed and edge cases are decided by senior engineers. That combination is the service: AI speed with an engineering quality bar.

Can you build a frontend for our existing backend or API?

Yes, that is the core use case. We take your REST or GraphQL API, agree on how the interface talks to it, and deliver a typed, tested interface without touching your server code. Your backend team keeps full ownership of their side.

Which frameworks do you use: React, Next.js or Astro?

All three, chosen by the job. React and Next.js for applications with rich state and auth, Astro for content and marketing sites where speed wins. Our own site runs on Astro and scores 100/100 in Lighthouse: that is the bar we build to.
