AI Analysis
●●●BangerWizardryEye CandyNiche Gem
WASM treemap visualizer beats Bloaty for instant firmware bloat diagnosis.
Strengths
- •Entirely Rust/WASM eliminates framework overhead—direct Canvas rendering is snappy
- •Clever hue-distribution algorithm ensures all colors used evenly across treemap
- •DWARF debug tracing infers ownership of unnamed .rodata sections, solving real embedded pain
Weaknesses
- •Limited to STM32/ESP32—macOS binary support missing, reducing cross-platform reach
- •Requires debug symbols (-g flag) or visualization is incomplete and unhelpful

Visualizing persistent vectors in the browser using Rust and WASM
Dragging the timeline reveals how splits, concats and shared nodes evolve across versions, which makes an abstract data structure palpably understandable. Running the implementation in-browser via Rust→WASM is a neat technical demo, but it's primarily educational — more inline explanations or scenarios would make it genuinely useful beyond hobbyist exploration.

Klarity Disk – A $6.99 DaisyDisk Alternative for Mac
Treemap plus icicle views and native SwiftUI builds give Klarity snappy local scans and a modern UI, with handy touches like Move to Trash and a menu-bar RAM monitor. It’s an attractive, lower-cost alternative to DaisyDisk with privacy (no telemetry) baked in — but it’s more refinement than innovation in an already crowded niche.
