Install

Grab the installer for your platform from the latest release:

Platform	File
macOS (Apple Silicon)	Easy Debugger_*_aarch64.dmg
macOS (Intel)	Easy Debugger_*_x64.dmg
Windows	_x64-setup.exe or _x64_en-US.msi
Linux	_amd64.deb · .x86_64.rpm · _amd64.AppImage
Android	easy-debugger_*_android.apk

The macOS and Windows builds are unsigned. On macOS, if you see "app is damaged", move it to /Applications and run:

xattr -cr "/Applications/Easy Debugger.app"
codesign --force --deep --sign - "/Applications/Easy Debugger.app"

On Windows, click More info → Run anyway on the SmartScreen prompt.

Development

Requires Node 22+, pnpm, Rust 1.90+; on macOS the Xcode Command Line Tools.

pnpm install
pnpm tauri dev      # run in dev
pnpm tauri build    # bundle → src-tauri/target/release/bundle

Mobile

The layout switches automatically by platform: three columns on desktop, a single column with a bottom tab bar and a bottom-sheet info panel on mobile. The core Rust logic is shared across both.

pnpm tauri android init && pnpm tauri android build   # needs Android Studio + NDK
pnpm tauri ios init && pnpm tauri ios build           # needs macOS + Xcode

Testing

cd src-tauri && cargo test   # unit tests + end-to-end tests for all five transports
pnpm vue-tsc --noEmit        # frontend type check

Project layout

• src/ — frontend: api/ command & event wrappers, stores/ state, components/ & views/ UI, i18n/ locales.
• src-tauri/src/ — backend: session/ transports, codec.rs encode/decode, framing.rs framing, dns.rs & net.rs tools, commands.rs command layer.
• docs/SPEC.md — full product spec (Chinese).
