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
