React Developers for AI Chat, Copilots and Agent Dashboards

Start with Next.js when public pages need to rank in search or load fast on the first visit, because it renders React on the server. Use plain React with Vite for logged-in apps and dashboards that search engines never see. Next.js is a React framework, so the same engineers work in both. The React team now points new projects to a framework or a build tool such as Vite. In Cortance's network, 66 of 317 React projects run on Next.js.

A React developer from Cortance's network typically costs $25-40 an hour, depending on seniority and on Next.js or AI interface experience, which sits toward the top of the range. Every engineer has passed five vetting stages: application, AI screening, HR interview, technical assessment with live coding and a completed profile.

A streaming AI chat needs a React engineer who can render tokens as they arrive without re-rendering the whole page. The interface also needs stop and retry controls, history that survives a reload and clear error states for timeouts. When the model uses tools or sources, show which ones. Keep the model API key on the server, never in the browser. Cortance matches engineers who have shipped AI chat, copilot or agent screens.

Move to Next.js when search traffic or first-load speed matters, or when the app still runs on Create React App, which the React team retired in February 2025. Move route by route, starting with public pages, and keep logged-in areas as they are until there is a reason to change them. Plan for upkeep too: React and Next.js ship security fixes for server rendering, so keep both up to date.

Choose the one your team will maintain. React suits products that may later need a mobile app, because React Native shares the language and patterns. In Cortance's network, 55 of the 317 React projects also use React Native. React also has the larger hiring pool in our network: 138 profiles against 43 for Vue. Vue suits teams that live mostly in Laravel or another backend. Our Vue.js page covers that case.

Many do: 9 of the 50 React engineers Cortance reviewed list Claude Code, and some also use Cursor or GitHub Copilot. These tools write components and tests quickly. The engineer still decides where state lives, checks accessibility and catches needless re-renders. React Compiler 1.0, released in October 2025, now memoizes components automatically, which removes some manual work but not the architecture decisions.

Cortance sends matched React candidates within 30 minutes of a clear brief. Every candidate has passed five vetting stages before you see a profile. For the closest match, say whether you need a new product, a Next.js move or an AI feature. Add your current stack and the screen that matters most.

Often, yes: 55 of the 317 React projects in Cortance's network also use React Native, so many engineers work on both. One engineer can share types, API clients and business logic between web and mobile, though screens are built separately. Bring in a dedicated React Native engineer when the app needs custom native modules, heavy animations or frequent App Store and Google Play releases.
