Vite 8.0 ships with its most significant architectural change since version 2: replacing the dual esbuild/Rollup bundler setup with Rolldown, a single unified Rust-based bundler. Real-world build time improvements range from 57% to 8x faster, with some projects dropping from 46 seconds to 6 seconds. The release maintains full plugin API compatibility and includes a built-in compatibility layer for migrating esbuild and Rollup options. Additional improvements include native tsconfig paths support, emitDecoratorMetadata support, browser console forwarding, and a new plugin-react v6 that swaps Babel for Oxc. A known compatibility issue exists with Yarn PnP on Windows. Vite 8 is positioned as a framework-agnostic alternative to Turbopack, downloaded over 65 million times weekly.
