typing-inspection
Runtime typing introspection tools
Decision gist · record as of 2026-08-14
Yes. The package is actively maintained, has no known vulnerabilities, carries a permissive MIT license, and fills a genuine need for runtime type introspection. Its low install friction and support for current Python versions make it a safe dependency. The Alpha status signals ongoing development, so pin the version if stability is critical, but the recent release cadence and active repository suggest it is production-ready for its intended use.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later.
- Actively maintained with a recent release (2 days old).
- Low install friction with a single runtime dependency on typing-extensions.

origin = get_origin(List[int])
args = get_args(List[int])- Specific capabilities beyond basic origin/args extraction (e.g., support for PEP 604 unions, TypedDict introspection, overload resolution).

- Compatibility guarantees with typing-extensions versions and edge cases in different Python 3.10–3.15 implementations.
What it is and what it does
typing-inspection is a runtime type annotation introspection library that lets you examine and extract information from Python's type hints at execution time. It wraps and extends the capabilities of the standard library's typing module, providing utilities to decompose generic types into their origin and arguments, and to inspect other type metadata that would otherwise require manual parsing.
The package targets developers building tools that need to reason about types dynamically—such as validation frameworks, serialization libraries, or code generation tools. It depends only on typing-extensions and is designed to work across modern Python versions (3.10–3.15). The library is actively maintained and currently in Alpha status, meaning its API may evolve, but it is receiving regular updates.
Use it for
- Validate or serialize objects based on their type annotations by extracting generic type parameters at runtime.
- Build introspection-based tools (e.g., ORM query builders, API schema generators) that need to reason about annotated types.
- Implement custom type checkers or validation frameworks that inspect type hints to enforce constraints.
- Debug or log type information from annotated function signatures and class attributes during execution.
- Decompose complex generic types (e.g., List[Dict[str, int]]) into their constituent parts for dynamic handling.
