A browser-based Rust analysis tool that reads public repositories and explains runtime behavior, from spawned processes to ignored checks.

Landing page captured for the 2026-09-19 issue.
For
Rust developers reviewing agent-written or unfamiliar code
Worth noticing
The browser demo analyzes source without cloning or building, and reports file, line, code, rationale, and suggested action.

Field notes

The homepage demonstrates the tool with named Rust repositories and exposes findings at file-and-line level rather than reducing them to a generic score. Its examples include a shell handed an unresolved argument and a child process launched with checks disabled. The implementation is described as WebAssembly running in the browser, with source fetched from a CDN and unchanged files reused on later visits.
