SWC is a Rust-based JavaScript/TypeScript compiler that's 20x faster than Babel. Used by Next.js, Deno, and Parcel as their compilation layer.
Reviewer scorecard
“The simplest way to get typed, validated outputs from LLMs. Pydantic integration is natural for Python developers.”
“20x faster than Babel with full compatibility. Used by Next.js which validates production readiness.”
“Does one thing perfectly. No over-abstraction, just structured outputs. The anti-LangChain.”
“Babel is effectively replaced. SWC's speed improvement is dramatic and the compatibility is excellent.”
“Structured outputs are the bridge between LLMs and traditional software. Instructor makes that bridge trivial to build.”
“SWC is the invisible engine powering modern JS tooling. Rust compilation speed enables new tool architectures.”
