What’s less widely known is that many large companies, including Microsoft and Canva, maintain their own internal versions of Rspack built on top of Rspack’s Rust API, allowing them to meet highly customized internal requirements and push performance even further. While this is not particularly friendly to Rspack’s download numbers, it is something we very much welcome. In fact, we created rspack-binding-template specifically to reduce the maintenance burden of maintaining an Rspack fork. We have similar practices internally as well, so we fully understand why teams choose this approach. Ultimately, what matters most to us is whether Rspack can meet users’ real-world needs—not whether we can maximize the apparent impact or adoption metrics of our own tooling.

Looks like ChatGPT is on Rspack now too 👀 Two AI giants. One bundler.
