Question: How is oxc.rs being adopted in the JavaScript ecosystem?

Answer:

OXC Adoption in the JavaScript Ecosystem

OXC has seen strong and rapid adoption since its initial release in late 2023. Here is a breakdown across different dimensions:

🏢 Notable Company Adopters

OXC is thankful for its 5,200 early adopters and for companies such as:

Shopify, where the front-end platform team uses Oxlint in the Shopify admin console.
Airbnb, where they use multi-file analysis (oxc/no-barrel-file and import/no-cycle) on their 126,000+ files, completing in just 7 seconds on CI.

Other notable users include Preact, ByteDance, and Shopee for linting, while Rolldown and Nuxt use OXC for parsing, and Nova, swc-node, and knip use oxc_resolver for module resolution.

📦 NPM Downloads

The oxc-parser npm package alone has ~2.6 million weekly downloads as of early 2026, indicating deep integration into downstream build tools and pipelines.

🔧 Tool-Level Adoption

Oxlint (Linter)

Oxlint reached its stable v1.0 release in June 2025, with a dedicated full-time maintainer and a growing core team. It now includes over 695 rules, covering most plugins teams already use, with automated migration tooling available.

Oxfmt (Formatter)

Oxfmt now passes 100% of Prettier’s JavaScript and TypeScript conformance tests, making migration from Prettier nearly seamless with no formatting differences expected.

Rolldown (Bundler — VoidZero)

OXC powers the entire parsing, transformation, and minification pipeline of Rolldown, which is the next-generation bundler planned to replace Rollup inside Vite — one of the most popular frontend build tools today.

🌱 Ecosystem Integration

OXC also offers an AI migration skill (npx skills add oxc-project/oxc --skill migrate-oxlint) to help teams automatically migrate from ESLint configs to Oxlint, lowering the friction of adoption.

⚠️ Caveats / Still Maturing

Oxfmt (formatter) and Oxc Transformer are still in alpha/beta stages.
The JS plugin system for Oxlint is in early preview; performance optimizations are still being applied and multiple x speed-ups are expected over the coming months.
Type-aware linting (alpha) relies on tsgolint, which is based on Microsoft’s Go-based TypeScript rewrite (typescript-go), which will become TypeScript v7.0 — still experimental.

Summary

OXC adoption is growing quickly, especially for linting at scale (Shopify, Airbnb), and is becoming infrastructure-level via Rolldown/Vite. The parser is broadly used across the ecosystem with millions of weekly downloads. The main gap remains in formatter and transformer maturity compared to well-established tools like Prettier and Babel.
