It runs in two primary modes: a PyRight-like mode for modern type checking and a Mypy-compatible mode that accepts the same configuration files, command-line flags, and error messages as Mypy. This makes it a drop-in replacement for teams already using Mypy who want better performance without rewriting their type-checking setup.\n\nThe package provides full LSP support, enabling IDE integration for real-time diagnostics, code completion, go-to-definition, find references, rename refactoring, hover information, and document highlights. It has no runtime dependencies, only requires Python 3.7 or later, and is distributed as pre-compiled wheels for macOS (Intel and ARM), Linux (multiple architectures including ARM), Windows, and musl-based systems. The project is actively maintained and carries an AGPL-3.0 license with commercial licensing available.","worth_installing":"Yes, if you need a faster type checker and can accept the AGPL-3.0 license (or purchase a commercial license). Zuban is actively maintained, has no runtime dependencies, and offers both Mypy and PyRight compatibility modes. The medium install friction is offset by pre-built wheels across many platforms. Verify performance claims and type system coverage against your specific codebase before committing to production use."},"id":"zuban","links":{"html":"https://skillfed.io/packages/zuban","md":"https://skillfed.io/packages/zuban.md","pypi":"https://pypi.org/project/zuban/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-07-31","license_spdx":"AGPL-3.0-only","license_treatment":"agpl","name":"zuban","python_support":"supports_current","summary":"Zuban - The Zuban Language Server"},"popularity":{"monthly_downloads":240357,"position":8905,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.9.1"}
