Rspack is a Rust-based bundler compatible with webpack. 5-10x faster builds while maintaining webpack plugin and loader compatibility.
Reviewer scorecard
“Open source with a self-hostable option. Remote config + feature flags in one tool reduces tool sprawl.”
“webpack compatibility with Rust speed. The migration path from webpack is smoother than switching to Vite or Turbopack.”
“Solid open-source feature flag platform. The edge proxy for sub-millisecond evaluation is a nice touch.”
“For webpack-heavy projects, Rspack provides the biggest speed improvement with the least migration effort.”
“The feature flag market is crowded. Flagsmith is good but differentiation is minimal against Unleash and others.”
“Rust-based JS tooling replacing JavaScript tooling is the trend. Rspack, Biome, and SWC prove it works.”
