Your code.
In the spotlight.

Find the expensive line. Follow the function. Keep your own source at the center of every investigation.

01 / SOURCE

Every line, in context.

Browse complete source snapshots with timing heatmaps and links to your own functions and classes.

02 / NOTEBOOKS

One session. One report.

Capture a single cell or a whole notebook, with stable source snapshots and child notebook navigation.

03 / SPARK

Follow the work.

Inspect action timing and executed plans while keeping driver time separate from executor metrics.
