LeakWatch

LeakWatch is a lightweight, easy-to-use Python library designed to help developers identify memory leaks and abnormal memory growth within Python applications.

Unlike traditional profilers that provide raw memory statistics, LeakWatch focuses on explaining:

• What is growing (which object types).
• Where it was created (source attribution / traceback).
• How fast it is growing (growth rate over time).
• Whether it is likely a memory leak (calculates a leak score).

Features

• Snapshot Comparison: Capture and compare memory states dynamically.
• Context Monitoring: Monitor code blocks or decorate functions using monitor.
• Source Attribution: Resolve file and line tracebacks for allocated objects.
• Leak Scoring: Intelligent heuristic to identify the probability of a leak.
• Command-Line Interface: Run your Python scripts under a monitor or export reports to JSON, Markdown, or HTML.

Installation

Install using pip:

pip install leakwatch-py

Quick Start

from leakwatch import watch

# Call watch at the start of your script
watch()

# Your application code runs...
