GoTrace is a CLI tool that analyzes Go execution traces produced by the Go runtime and renders a 3D WebGL visualization of concurrency flow in the browser. It is primarily an educational tool for understanding Go's goroutine and scheduler behavior in small, short-running programs.

Use cases

• visualize goroutine concurrency in 3d
• understand go scheduler behavior
• teach go concurrency patterns
• analyze go execution traces visually
• debug goroutine interactions in small programs
• render go trace files as webgl animation

When to choose

• you are learning or teaching Go concurrency concepts
• you want an intuitive visual view of goroutine scheduling in short traces
• you want to explore how channels and goroutines interact over time

When to avoid

• you need production performance profiling of long-running programs
• your traces are large or your program runs for a long time
• you need standard go tool trace analysis rather than 3D visualization
• you cannot patch the Go runtime or use the provided Docker image
