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
