birdseye is a Python debugger which records the values of expressions in a function call and lets you easily view them after the function exits. For example:

Hovering over expressions

Rather than stepping through lines, move back and forth through loop iterations and see how the values of selected expressions change:

Stepping through loop iterations

See which expressions raise exceptions, even if they’re suppressed:

Exception highlighting

Expand concrete data structures and objects to see their contents. Lengths and depths are limited to avoid an overload of data.

Exploring data structures and objects

Calls are organised into functions (which are organised into files) and ordered by time, letting you see what happens at a glance:

birdseye can be used no matter how you write or run your code, requiring only a browser for the interface. But it's also integrated with some common tools for a smoother experience.
