Netguru also works with Next.js, making it suitable for products that need server-side rendering or static generation alongside the React component layer.

A-listware provides dedicated software teams and individual engineers who can join a client's development organization. React and Next.js are part of a wider frontend stack that also includes JavaScript, TypeScript, Angular, and Vue.

net-devs provides senior-led engineering teams for enterprise software projects. Its frontend capabilities cover React, Angular, and Vue with TypeScript and frontend testing included as part of the development process.
