Top 6 SWC Alternatives
SWC is a high-performance compiler for TypeScript and JavaScript, built in Rust. It offers fast compilation and modern transformation features, making it appealing for faster build times.
Like any tool, SWC has its own set of limitations. Setting it up for development workflows can be a bit more involved, and its ecosystem isn’t as mature as some well-known tools. It primarily handles build-time tasks rather than runtime, too. The good news is, there are many great alternatives out there that can offer better usability and a more robust ecosystem.
This guide examines the six most compelling alternatives to SWC for TypeScript compilation and transformation.
SWC key features
SWC is highly efficient at fast compilation thanks to its Rust-based design. It offers advanced transformations for TypeScript and JavaScript, supports modern language features, and includes built-in bundling and minification. The tool also features a plugin architecture for extension and provides significantly quicker compilation compared to traditional JavaScript tools.

1. esbuild
esbuild is SWC's main competitor when it comes to raw compilation speed. Developed in Go, it offers very rapid TypeScript compilation, strong bundling features, and a more mature ecosystem than SWC.
🌟 Key features
- Extremely fast compilation written in Go
- Advanced bundling and tree-shaking capabilities
- Extensive plugin ecosystem
- Built-in development server support
➕ Pros
- Matches SWC's compilation speed while offering easier setup and configuration
- More mature ecosystem with better documentation and community support
- Excellent bundling capabilities that work well for both development and production
- Better integration with existing JavaScript tooling compared to SWC's Rust-based approach
➖ Cons
- Slightly larger resource footprint compared to SWC's minimal overhead
- Less advanced transformation capabilities for complex TypeScript features
- Plugin system not as extensive as SWC's growing ecosystem
2. TypeScript Compiler (tsc)
The TypeScript Compiler remains the official and most comprehensive solution for TypeScript compilation. While significantly slower than SWC, it provides complete language support and the most accurate type checking available.
🌟 Key features
- Official TypeScript implementation with complete language support
- Comprehensive type checking and error reporting
- Incremental compilation for improved build times
- Extensive configuration options
➕ Pros
- Most accurate and complete TypeScript support, handling edge cases that SWC might miss
- Comprehensive type checking catches errors during compilation that SWC's focus on speed might overlook
- Extensive configuration options allow fine-tuning for specific project requirements
- Guaranteed compatibility with all TypeScript features and future language updates
➖ Cons
- Significantly slower compilation compared to SWC, especially for large codebases
- Higher memory consumption during compilation processes
- No built-in bundling capabilities like SWC provides
3. Bun
Bun provides an all-in-one JavaScript runtime that includes extremely fast TypeScript compilation. It matches SWC's speed while offering runtime execution, package management, and testing capabilities in a single tool.
🌟 Key features
- All-in-one runtime with built-in TypeScript compilation
- Extremely fast transpilation and execution
- Integrated package manager and test runner
- Native bundling and optimization
➕ Pros
- Matches SWC's compilation speed while providing runtime execution capabilities
- Simpler setup compared to SWC's build-focused workflow
- Combines compilation, runtime, package management, and testing in one tool
- Excellent performance for both development and production builds
➖ Cons
- Requires replacing the entire JavaScript runtime, while SWC integrates with existing Node.js setups
- Newer ecosystem with fewer third-party integrations compared to established tools
- Some Node.js API compatibility differences could affect existing projects
4. Vite
Vite offers a modern build tool that uses esbuild internally for TypeScript compilation while providing an excellent development experience. It focuses on developer productivity rather than pure compilation speed like SWC.
🌟 Key features
- Fast development server with Hot Module Replacement
- esbuild-powered TypeScript compilation
- Extensive plugin ecosystem
- Production bundling with Rollup
➕ Pros
- Excellent development experience with instant server startup and fast HMR
- Large and active ecosystem with extensive plugin support
- Better development tooling integration compared to SWC's build-focused approach
- Mature toolchain with excellent documentation and community support
➖ Cons
- Slower compilation than SWC for pure build scenarios
- More complex setup for non-web projects where SWC might be simpler
- Larger bundle size due to comprehensive feature set
5. Babel
Babel serves as the established standard for JavaScript and TypeScript transformation. While much slower than SWC, it offers the most extensive plugin ecosystem and transformation capabilities available.
🌟 Key features
- Extensive plugin ecosystem for custom transformations
- Mature toolchain with wide industry adoption
- Comprehensive browser compatibility handling
- Advanced transformation and polyfill capabilities
➕ Pros
- Most extensive plugin ecosystem allows custom transformations impossible with SWC
- Mature toolchain with excellent documentation and community support
- Superior browser compatibility handling through comprehensive polyfill support
- Battle-tested in production environments across thousands of projects
➖ Cons
- Significantly slower compilation compared to SWC's Rust-based performance
- Much larger bundle size and memory footprint during builds
- Complex configuration required for advanced use cases
6. tsx
tsx provides a runtime TypeScript execution tool built on esbuild. While different from SWC's build-focused approach, it offers extremely fast TypeScript compilation with immediate execution capabilities.
🌟 Key features
- esbuild-powered compilation with runtime execution
- Built-in watch mode and REPL support
- Simple setup with minimal configuration
- Excellent module format compatibility
➕ Pros
- Extremely fast TypeScript compilation and execution, rivaling SWC's build speeds
- Much simpler setup compared to SWC's build toolchain requirements
- Excellent for development workflows with built-in watch mode and REPL
- Smaller learning curve for developers familiar with Node.js workflows
➖ Cons
- Focused on runtime execution rather than production builds that SWC targets
- Less suitable for complex build pipelines where SWC excels
- No advanced transformation capabilities for complex TypeScript features
Final thoughts
This guide reviewed six SWC alternatives, each with unique strengths. For speed and ecosystem support, esbuild is best.
Projects needing precise type checking should stick with the official TypeScript compiler, despite its slower speed. Bun offers SWC-like speed, runtime features, and tools, while Vite emphasizes developer experience with fast compilation and modern features.
Babel is highly customizable through its plugins, but less performant. Lastly, tsx is ideal for rapid prototyping, offering fast compilation and instant execution.
