VoidZero is the JavaScript tooling company building a unified, high-performance open-source toolchain for web development: the build tool Vite, the test runner Vitest, the Rust-based bundler Rolldown, and the Oxc language toolchain (including the oxlint linter and oxc-parser), all brought together under the commercial unified entry point Vite+. Founded by Evan You, creator of Vite and Vue.js, and backed by Accel and Peak XV, VoidZero joined Cloudflare in 2026. The company ships its capabilities as open-source npm packages and command-line tools rather than as a hosted REST API.
