Vite is a front-end build tool and dev server created by the Vue.js team, now used broadly across React, Vue, and Svelte projects as a faster alternative to older bundlers like Webpack. Because it's a build-time tool rather than a runtime library, detecting Vite in production relies on residual artifacts it leaves in generated asset filenames and module-loading markup — our engine matches 1 script pattern and 2 HTML patterns tied to those conventions. A Vite detection tells you how a site was built, not what framework runs on top of it or where it's hosted. Documented at vitejs.dev.
