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.
Performance & Unifying Executables
v0.0.20: Performance The latest release (v0.0.20) brings both performance improvements and a unified way of accessing the type checker and language server.
Passing Conformance Tests
Conformance with Python’s Typing Tests In version 0.0.19, ZubanLS now passes a large number of Python typing conformance tests , bringing it even closer to Mypy’s behavior.
Extended LSP Support
Improved Support for IDE Users I’m excited to share that ZubanLS now supports a much broader set of Language Server Protocol features.
Public Alpha Release
A Personal Note After five years of hard work, I'm proud to release the first alpha of ZubanLS. My journey began in 2012 with the creation of Jedi —a Python auto-completion library that would go on to reach millions of users and billions of downloads. If you’re encountering issues, I’d love to hear about them. I’m especially interested in real-world cases, and I encourage you to reach out to us .
