NextJS is a powerful React-based framework used to build server-side rendered web applications that has become increasingly popular over the years. However, there are a few competitors out there that provide an alternative solution. Gatsby, Nuxt.js, Angular, and Svelte are all great alternatives to NextJS, each offering a different feature set with a few extra advantages. Ultimately, the choice of which framework to use will depend on the specific needs and requirements of your project.
