CLI
The Wails CLI has a number of commands that are used for managing your projects. All commands are run in the following way:
wails <command> <flags>
init
wails init is used for generating projects.
| Flag | Description | Default |
|---|---|---|
| -n "project name" | Name of the project. Mandatory. | |
| -d "project dir" | Project directory to create | Name of the project |
| -g | Initialise git repository | |
| -l | List available project templates | |
| -q | Suppress output to console | |
| -t "template name" | The project template to use. This can be the name of a default template or a URL to a remote template hosted on github. | vanilla |
| -ide | Generate IDE project files | |
| -f | Force build application | false |
Example: wails init -n test -d mytestproject -g -ide vscode -q
This will generate a a project called "test" in the "mytestproject" directory, initialise git, generate vscode project files and do so silently.
More information on using IDEs with Wails can be found here.
Remote Templates
Remote templates (hosted on GitHub) are supported and can be installed by using the template's project URL.
Example: wails init -n test -t https://github.com/leaanthony/testtemplate[@v1.0.0]
A list of community maintained templates can be found here
The Wails project does not maintain, is not responsible nor liable for 3rd party templates!
If you are unsure about a template, inspect package.json and wails.json for what scripts are run and what packages are installed.
build
wails build is used for compiling your project to a production-ready binary.
| Flag | Description | Default |
|---|---|---|
| -clean | Cleans the build/bin directory | |
| -compiler "compiler" | Use a different go compiler to build, eg go1.15beta1 | go |
| -debug | Retains debug information in the application and shows the debug console. Allows the use of the devtools in the application window | |
| -devtools | Allows the use of the devtools in the application window in production (when -debug is not used). Ctrl/Cmd+Shift+F12 may be used to open the devtools window. NOTE: This option will make your application FAIL Mac appstore guidelines. Use for debugging only. | |
| -dryrun | Prints the build command without executing it | |
| -f | Force build application | |
| -garbleargs | Arguments to pass to garble | -literals -tiny -seed=random |

| -o filename | Output filename | |
| -obfuscated | Obfuscate the application using garble | |
| -platform | Build for the given (comma delimited) platforms eg. windows/arm64. Note, if you do not give the architecture, runtime.GOARCH is used. | platform = GOOS environment variable if given else runtime.GOOS.arch = GOARCH envrionment variable if given else runtime.GOARCH. |
| -race | Build with Go's race detector | |
| -s | Skip building the frontend | |
| -skipbindings | Skip bindings generation | |
| -tags "extra tags" | Build tags to pass to Go compiler. Must be quoted. Space or comma (but not both) separated | |
| -trimpath | Remove all file system paths from the resulting executable. | |
| -u | Updates your project's go.mod to use the same version of Wails as the CLI | |
| -upx | Compress final binary using "upx" | |
| -upxflags | Flags to pass to upx | |
| -v int | Verbosity level (0 - silent, 1 - default, 2 - verbose) | 1 |
| -webview2 | WebView2 installer strategy: download,embed,browser,error | download |
| -windowsconsole | Keep the console window for Windows builds |
For a detailed description of the webview2 flag, please refer to the Windows Guide.
If you prefer to build using standard Go tooling, please consult the Manual Builds guide.
Example:
wails build -clean -o myproject.exe
On Mac, the application will be bundled with Info.plist, not Info.dev.plist.
There are issues with using UPX with Apple Silicon.
Some Antivirus vendors false positively mark upx compressed binaries as virus, see issue.

dev
wails dev is used to run your application in a "live development" mode. This means:
- The application's
go.modwill be updated to use the same version of Wails as the CLI - The application is compiled and run automatically
- A watcher is started and will trigger a rebuild of your dev app if it detects changes to your go files
- A webserver is started on
http://localhost:34115which serves your application (not just frontend) over http. This allows you to use your favourite browser development extensions - All application assets are loaded from disk. If they are changed, the application will automatically reload (not rebuild). All connected browsers will also reload
- A JS module is generated that provides the following:
- JavaScript wrappers of your Go methods with autogenerated JSDoc, providing code hinting
- TypeScript versions of your Go structs, that can be constructed and passed to your go methods
- A second JS module is generated that provides a wrapper + TS declaration for the runtime
- On macOS, it will bundle the application into a
.appfile and run it. It will use abuild/darwin/Info.dev.plistfor development.
| Flag | Description | Default |
|---|---|---|
| -appargs "args" | Arguments passed to the application in shell style | |
| -assetdir "./path/to/assets" | Serve assets from the given directory instead of using the provided asset FS | Value in wails.json |
| -browser | Opens a browser to http://localhost:34115 on startup | |
| -compiler "compiler" | Use a different go compiler to build, eg go1.15beta1 | go |
| -debounce | The time to wait for reload after an asset change is detected | 100 (milliseconds) |
| -devserver "host:port" | The address to bind the wails dev server to | "localhost:34115" |
| -extensions | Extensions to trigger rebuilds (comma separated) | go |
| -forcebuild | Force build of application | |
| -frontenddevserverurl "url" | Use 3rd party dev server url to serve assets, EG Vite | "" |
| -ldflags "flags" | Additional ldflags to pass to the compiler | |
| -loglevel "loglevel" | Loglevel to use - Trace, Debug, Info, Warning, Error | Debug |
| -nocolour | Turn off colour cli output | false |
| -noreload | Disable automatic reload when assets change | |
| -nosyncgomod | Do not sync go.mod with the Wails version | false |
| -race | Build with Go's race detector | false |

| -s | Skip building the frontend | false |
| -save | Saves the given assetdir, reloaddirs, wailsjsdir, debounce, devserver and frontenddevserverurl flags in wails.json to become the defaults for subsequent invocations. | |
| -skipbindings | Skip bindings generation | |
| -tags "extra tags" | Build tags to pass to compiler (quoted and space separated) | |
| -v | Verbosity level (0 - silent, 1 - standard, 2 - verbose) | 1 |
| -wailsjsdir | The directory to generate the generated Wails JS modules | Value in wails.json |
Example:
wails dev -assetdir ./frontend/dist -wailsjsdir ./frontend/src -browser
This command will do the following:
- Build the application and run it (more details here
- Generate the Wails JS modules in
./frontend/src - Watch for updates to files in
./frontend/distand reload on any change - Open a browser and connect to the application
There is more information on using this feature with existing framework scripts here.
