Editorial interest 83/100 Selection signal · not a rating of the site

A static-analysis tool maps an app’s components and connections, with evidence for each part.

Landing page captured for the 2026-10-15 issue.

For: Developers inspecting desktop and Android apps
Worth noticing: Relationship labels distinguish directly observed links, inferred links, IPC, and the site's own heuristics.

Field notes

REA describes its engine as static analysis and labels relationships as observed, inferred, IPC, or a studio heuristic. The page offers demos across Electron, Windows, Linux, macOS, and Android, including a seven-file hand-written Electron sample with a known answer key. Real-app examples are not uniformly complete: GitHub Desktop is shown as a trimmed fixture, while the VS Code example covers selected main-process and preload files.
