It uses Python's garbage collection mechanism to traverse object graphs without recursive calls, making it faster and safer than naive approaches. The package automatically filters out shared objects like None, types, modules, classes, and functions, since these are typically shared across many instances and shouldn't be counted multiple times.\n\nYou can measure single objects, multiple objects at once, or exclude specific subtrees from the calculation. The library offers customization hooks: you can define your own size calculation, referent discovery, and filtering logic to handle special cases like torch tensors or weakref proxies that don't expose their memory through Python's standard introspection. It also provides a traversal API to walk the entire object graph yourself.","worth_installing":"Yes. objsize is a straightforward, dependency-free memory profiling tool with no known vulnerabilities, permissive licensing, and broad Python version support. Install it if you need to measure object memory consumption beyond what sys.getsizeof() provides. The aging maintenance status is not a blocker for a stable utility library, but check the documentation to confirm it handles your Python version and object types."},"id":"objsize","links":{"html":"https://skillfed.io/packages/objsize","md":"https://skillfed.io/packages/objsize.md","pypi":"https://pypi.org/project/objsize/"},"maintenance":{"status":"aging"},"meta":{"latest_release":"2026-01-18","license_spdx":null,"license_treatment":"permissive","name":"objsize","python_support":"supports_current","summary":"Traversal over Python's objects subtree and calculate the total size of the subtree in bytes (deep size)."},"popularity":{"monthly_downloads":2995494,"position":2795,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"0.8.0"}
