Warning
Early Development Phase: This project is in its very early stages and is NOT ready for production use.
oxc-plugin-react-compiler is an experimental project aiming to port the original babel-plugin-react-compiler to a Rust-based implementation on top of the OXC toolchain.
Note
Disclaimer: This is a community-driven project (still very new!). It is not an official project from the React team or OXC, and we are not affiliated with Meta, the React core team, or the OXC project.
The primary goal is to achieve exact behavior alignment with the original React Compiler implementation while leveraging the performance benefits of Rust.
We have achieved a significant milestone in conformance testing: 1752 parity successes, 0 parity failures, 0 skipped. This was verified by running the conformance test suite against the upstream React Compiler fixtures (cargo run --package conformance --bin conformance -- --update --include-errors --verbose). While still experimental, this demonstrates near-complete behavioral alignment with the original implementation.
This project serves as an experiment to explore AI-assisted development in complex compiler porting tasks. The codebase is being heavily co-developed with AI assistants including Claude Code and Codex. Due to API rate limits and the inherent complexity of the task, development is expected to span several months. The initial primitive implementation took about a month to prove the viability of a Rust-based React compiler.
- Primitive implementation proving viability in Rust.
- Align behavior exactly with the upstream React Compiler (verified via conformance tests).
- Provide seamless integration with Vite v8 (currently in beta).
- Offer a Rolldown / Vite plugin.
- Future exploration: Add support for SWC alongside OXC.

This project wouldn't be possible without the incredible work of the following teams and tools:
- The React Team: For the original React Compiler architecture, logic, and conformance fixtures.
- The OXC Team: For the blazingly fast Rust-based JavaScript toolchain that powers this port.
- Claude Code and Codex: Heavily relied upon to analyze, explore, implement, test, and literally anything else to this project.
