Use Vite for any modern frontend project: React, Vue, Svelte, or vanilla JavaScript. It's the current standard for new projects, replacing Create React App. Also use it as the build tool underlying frameworks like Astro and SvelteKit.
Use Vitest for any Vite-based project (React, Vue, Svelte) that needs unit or integration tests. It's also a good Jest replacement in non-Vite Node projects that want faster test execution and native ES module support.
For server-rendered apps (Next.js, Remix, Nuxt), the framework handles the build tool. For very old browsers that don't support ES modules, you'll need additional configuration. Large monorepos may need Turborepo or Nx on top of Vite to manage builds across packages.
For Next.js projects, Jest is still the recommended and better-documented choice. Vitest's browser mode (for running tests in a real browser) is still maturing — for end-to-end browser tests, use Playwright or Cypress.
