What's Good

MIT (lovablelabs/oj). Drop-in-minded React toolchain with streaming SSR (`oj dev --ssr` / `oj build --ssr`), Fast Refresh, and a persistent Node plugin host for Vite/Rollup-style plugins. Built where many parallel agent/CI builds make Vite’s memory profile expensive. Intro notes at rapha.land. ★~409.

The Catch

Vs Vite (default SPA/library toolchain) and Rolldown/Oxc-adjacent Rust tooling: OJ is the agent/CI-memory-oriented React builder, not the ecosystem default yet. Young Lovable Labs surface — verify plugin compatibility before you rip Vite out of a production app.

Verdict

MIT Rust React builder. Reach for it when parallel agent/CI builds make Vite’s memory cost the bottleneck.
