Pympler is a pure-Python development library for measuring, monitoring, and analyzing the memory behavior of Python objects in a running application. It combines object size measurement (asizeof), online monitoring (mumpy), class tracking, and a web profiling frontend for garbage visualization.
Use cases
- find memory leaks in a python application
- measure the size of python objects in bytes
- track object lifetimes and memory bloat over time
- monitor memory usage of a running python process
- visualize garbage collector statistics
- profile which classes consume the most memory
When to choose
- you need to debug memory bloat or leaks in pure Python code
- you want object-level size and lifetime analysis without native dependencies
- you need a zero-dependency memory profiling tool on Linux or macOS
When to avoid
- you need C-level or native heap profiling (use valgrind or memray instead)
- you need production APM or continuous memory monitoring
- your project requires active feature development
