Devhub

Native egui/eframe desktop app that scans filesystems and SSH hosts for software projects (Cargo.toml, package.json, go.mod, etc.), indexes them, and presents a three-pane browser with file tree, content search, git state, and telemetry.

cargo run --release # from the project root, requires rust 2024
