VoidZero's Oxfmt Formatter Reaches Beta with Full Prettier Compatibility, Running 36x Faster
Key Takeaways
- ▸Oxfmt beta achieves 100% Prettier compatibility while running up to 36x faster, with adoption by teams at Turborepo, Hugging Face, and Lichess
- ▸Vite 8 beta introduces experimental devtools for inspecting module graphs and debugging HMR updates in-browser
- ▸Rolldown and Oxc continue performance improvements with 9.6% and 4-6% speed gains respectively through optimization work
Summary
VoidZero has announced that Oxfmt, its Rust-based code formatter, has reached beta status with 100% compatibility with Prettier's JavaScript and TypeScript conformance tests while delivering performance up to 36 times faster. The beta release stabilizes experimental features from the alpha including import sorting, Tailwind CSS class sorting, and embedded language formatting. The company designed Oxfmt for easy migration by matching Prettier's output exactly, keeping migration pull requests minimal and reviewable. The formatter is already being used by notable teams including Turborepo, Hugging Face, Lichess, and Oxide Computer.
Alongside the Oxfmt announcement, VoidZero shared updates across its tooling ecosystem. Vite 8 beta now includes experimental devtools that enable developers to inspect module graphs, analyze transform timelines, and debug Hot Module Replacement (HMR) updates directly in the browser. The company also launched a plugin registry to help developers discover Vite plugins published on npm. Vitest 4.1 beta introduced new aroundEach and aroundAll hooks for wrapping tests in context or tracing spans.
Performance improvements continue across VoidZero's Rust-based tools, with Rolldown becoming up to 9.6% faster through optimized internal file path handling, and Oxc's semantic analysis seeing 4-6% speed improvements from hash precomputing for identifiers. The company revealed that several major projects are adopting its toolchain, including Nest.js migrating to Vitest from Mocha, Cloudflare releasing vinext (Next.js on Vite 8), and Astro working on a Rust compiler based on Oxc.

Editorial Opinion
VoidZero's strategy of achieving exact Prettier compatibility before introducing opinionated features demonstrates mature product thinking that prioritizes adoption friction over technical purity. The 36x performance improvement is impressive, but the real innovation is making migration so seamless that teams can switch formatters without controversial code style debates. The broader ecosystem momentum—from Cloudflare to Nest.js to Astro—suggests VoidZero's Rust-based toolchain is crossing the chasm from early adopters to mainstream JavaScript infrastructure.
