React is a free, open-source JavaScript library from Meta for building user interfaces out of components. Each block of the page has its own logic, and frameworks like Next.js grow it into full applications. Synapse Team is a React development company: interfaces, interactive website elements and complete products. ## What we build with React Pick the service that matches your project, or start the brief and we route it for you. 01 ### Frontend development Interfaces and design systems in React and TypeScript.

[MVP development](https://synapseteam.com/services/mvp-development/) 05 ### Storefront UIs Carts, filters and checkout that respond instantly. [Storefront UIs](https://synapseteam.com/services/ecommerce-development/) 06 ### Websites Fast websites with React only where interactivity is needed. [Websites](https://synapseteam.com/services/web-development/) ## When we choose React React is worth it when the interface has real logic: forms, filters, live data, drag and drop. Components keep that complexity under control, and the ecosystem has a proven solution for almost any task. - Dashboards, SaaS and client portals with lots of interaction - Design systems: one component library across the product - Interactive elements on Astro sites: only where they are needed - Next.js when the product must be fast and visible in Google ## When we recommend something else Not every project needs React. Here is when we honestly recommend another option, and build it ourselves. - Content pages without interaction: plain HTML loads faster - A marketing site or blog: Astro is faster - Your team is used to the WordPress admin: classic WordPress - A native mobile app: React Native, a separate project with its own estimate Technologies we build with [Astro](https://synapseteam.com/technologies/astro/) [Payload CMS](https://synapseteam.com/technologies/payload-cms/) [Next.js](https://synapseteam.com/technologies/nextjs/) [Vendure](https://synapseteam.com/technologies/vendure/) [TypeScript](https://synapseteam.com/technologies/typescript/) [Node.js](https://synapseteam.com/technologies/nodejs/) [WordPress](https://synapseteam.com/technologies/wordpress/) [Laravel](https://synapseteam.com/technologies/laravel/) ## AI-fast or classic: you choose the pace AI speeds up development, engineers guarantee quality: a senior engineer reviews every component and test before release. Prefer a traditional process? We run that too, with the same quality bar. Option A ### Classic build Traditional cycle with the same team and quality gates.

Pages, data and server rendering come from frameworks built on top, most often Next.js. In practice we choose per project: React alone for interactive elements of a website, Next.js for full applications. ### How much does React development cost? The library does not change our pricing: - SaaS MVP on React: AI from $4,000 (4–6 weeks), classic from $10,000 (10–12 weeks). - Internal tool on React: AI from $4,000 (3–6 weeks), classic from $6,500 (6–10 weeks). Describe your project in the chat and the team sends a precise fixed-price estimate within one business day. ### Is React frontend or backend? React is a frontend library: it runs the interface. The backend comes from Node.js, Next.js server code or a CMS like Payload. On our own site, for example, React powers the admin panel, while the public pages are plain HTML. ### Does a regular website need React? Not always, and we say so before the work starts. If a page is mostly content, plain HTML is faster: our own site serves its pages that way and keeps React for the admin panel. React is worth it when the interface has real logic. ### React or React Native: what is the difference? React builds web interfaces that run in the browser. React Native uses the same approach to build native mobile apps. We work with React on the web. We estimate a mobile app separately and say so honestly during the brief.
