Zuban ❤️ Open Source
Finally Open Source
I’m excited to share that Zuban is now Open Source under the AGPL license. This wasn’t my original plan—I initially envisioned a freemium model—but with the arrival of Ty and PyreFly, that path no longer made sense.
Zuban is already in a strong position as both a type checker and a language server, with most of the core work done and solid support for key LSP features. Rather than an ending, this open-source release marks a new beginning, and I hope the community will see the value in what Zuban can offer.
