Symbol Node Graph
Your workspace, nested the way Rust nests it.
- Everything that depends on a symbol lights up in rings around it
- The Connections pane counts what a change touches, in symbols and files
- Spring layout shows how code is organized; gravity shows how it's used
Thermal Vision Profiler
Color the node graph by where your program spends its time. Windows only.
- One click builds, runs and samples your program 8,000 times a second
- Hot functions glow, and call edges thicken with traffic
- The Profile pane ranks the hottest, with callers and callees
Function Flow Graph
What a function calls, as an outline you unfold.
- Callees as indented cards, from any function or from main
- Every type in a signature is a chip you can click
- Ride an arrow to the card at its far end
Code Health
Find what nothing uses, and what your changes touch.
- Dead code found by reachability, chains of it included
- Everything your uncommitted changes affect, before you push
- A list of every symbol nothing references
Code Structure
Reshape crates and modules from the graph.
- Rename symbols, modules and folders everywhere they're used
- Move, promote, demote or dissolve modules and crates
- Refuses edits that would create cycles or break the orphan rule
Workflow
Keyboard-first, in the colors you like.
- Walk the whole tree from the keyboard while the camera follows
- The History pane steps back through everywhere you've looked
- 209 of the most commonly used themes
CLI
Every report runs without the window, ready for scripts and CI.
--diffreports what your uncommitted changes affect--statscounts symbols and finds the most-referenced--comparechecks the native indexer against rust-analyzer
