The record

Purpose: Rspack is a fast Rust-based bundler for the web that modernizes the webpack API to support replacing webpack.
Architecture: Rspack combines Rust and TypeScript with a parallelized architecture.
Hot module replacement: Rspack uses incremental compilation to optimize hot module replacement performance.
Webpack ecosystem: Rspack is compatible with almost all community loaders, and over 85% of the 50 most downloaded webpack plugins can be used with Rspack or have an alternative.
Compatibility limit: Rspack does not aim for full webpack API compatibility; it prioritizes commonly used APIs and adds others based on user needs.
Built-in features: The homepage lists code splitting, tree shaking, asset management, a dev server, parallel builds, SWC, Lightning CSS, and a JavaScript build API.
Framework integrations: The documentation lists integrations for React, React Server Components, Preact, Vue, Next.js, Node.js applications, NestJS, Solid, Svelte, and Rstest.
Plugin and loader development: Custom plugins and loaders can be developed in JavaScript or Rust.
Release status: The introduction says Rspack 1.0 was released in August 2024 and describes it as production-ready because it covers most webpack APIs and features.
Support: The project directs users with questions to its Discord support channel or GitHub Discussions.
Security-related feature: The community plugin compatibility list includes a SubresourceIntegrityPlugin for output and assets.
Maintainer: The Rstack development team is led by ByteDance's web infrastructure team and works with community contributors on Rspack and related projects.
