basedpyright is a fork of Microsoft's pyright static type checker for Python with additional type checking improvements and pylance features built into the language server. It ships as a CLI, a language server, and editor extensions for VS Code, Sublime Text, and other LSP-capable editors.

Use cases

• static type checking for python code
• get pylance features without vscode
• run a python type checker in ci
• improve python type checking beyond pyright
• python language server for sublime text
• check python typing errors in the editor

When to choose

• you want pyright with stricter and more configurable type checking
• you need pylance-like features in editors other than vscode
• you want a free, self-hosted alternative to pylance

When to avoid

• you want the officially supported microsoft pyright
• you need a runtime type checker rather than static analysis
• you rely on pylance's proprietary closed-source features exactly as shipped
