See stack vs heap, pointers, escape analysis hints, and interface fat pointers updated as code executes.

Interactive

Stepper like Python Tutor

Advance line by line, watch variables mutate, visualize function frames, and highlight goroutine creation.

Interactive

Concurrency visualized

G/M/P scheduler diagrams, channel queues, mutex state, race-condition explainer overlays.

Interactive

Data structure deep-dives

Arrays, slices, maps, and structs rendered with alignment, padding, capacity growth, and bucket hashing.

Interactive
