## What it is
Birdseye is a graphical Python debugger that records the values of all evaluated expressions in a decorated function call and lets you inspect them in a browser after execution. It supports navigating loop iterations, spotting exceptions (even suppressed ones), and expanding data structures interactively.

## Use cases
- debug python code by inspecting expression values after a function runs
- step through loop iterations and see how values change
- find which expressions raise exceptions even when suppressed
- explore nested data structures and object contents during debugging
- debug code without changing how it is run, just add a decorator

## When to choose
- you want post-hoc inspection of expression values rather than line-by-line stepping
- you need to debug code run in any environment with minimal setup (pip install + decorator)
- you want to trace exceptions inside try/except blocks
- you prefer a visual, browser-based debugging interface

## When to avoid
- you need a traditional step debugger with breakpoints in your IDE
- performance overhead from recording all expressions is unacceptable
- you are debugging code you cannot modify to add decorators
- you need to debug multithreaded or distributed processes
