SWC has become the go-to Babel replacement for teams where transpilation performance matters. Next.js uses SWC as its default compiler, Jest uses it via @swc/jest for faster TypeScript transformation, and many build tools have adopted it for speed-critical compilation paths. Confidence is docs-derived.
SWC handles TypeScript transpilation, JSX transformation, modern JavaScript downleveling, and module transformation. The API covers CLI, Node.js bindings (@swc/core), and Jest integration (@swc/jest).
SWC is a local build tool with no platform auth. Rust binary installation via npm; no external services. Build pipeline integration uses standard environment variables.
Operationally, SWC is 20-70x faster than Babel for transpilation benchmarks. Type checking is not performed by SWC -- teams still need tsc for type checking, just not for compilation. The speed wins are most noticeable in large codebases with complex type hierarchies.
Documentation at swc.rs covers configuration, plugins, and framework integration. The speed advantage is well-documented. Developer experience is excellent when replacing Babel -- most configurations are straightforward substitutions.
