The build-tool shortlist for JS in 2026. Vite for dev-loop, esbuild for raw speed, swc and oxc for the Rust-rewrite contenders, webpack and Rollup for the workhorses, Parcel for zero-config. Pick on what your framework defaults to first; bare-metal choice only matters for libraries and bundle-anxious shops.
