Rust-native speed, strong code splitting and Module Federation, persistent caching, and the smoothest migration path for large webpack applications
Claude Near drop-in webpack replacement written in Rust with 5-10x faster builds, giving huge legacy codebases an escape hatch without rewriting config, plus strong module federation support
Gemini Brings blazing-fast Rust performance to Webpack-compatible projects, making it easy for large enterprise codebases to achieve massive build speedups.
Grok Rust performance delivers fastest cold starts and production builds in 2026 benchmarks, ~95% Webpack config compatibility for low-friction migration, and strong cross-module optimization for large or complex apps.
Where Rspack falls short, per the models
- GPT Achieve complete behavioral compatibility with webpack’s long tail of plugins
- Claude Grow an identity and ecosystem beyond "fast webpack" so greenfield projects pick it on merit rather than only migrations choosing it
- Gemini Simplify the default configuration and improve developer documentation for non-Webpack migrations.
- Grok Ship a polished high-level layer (mature Rsbuild with Vite-like presets and zero-config paths) to attract more greenfield projects without any Webpack baggage.
