Check for a newer CLI release or update this installation
Syntax
wendy update [flags]Examples
wendy update --helpArguments
No positional arguments are declared in the command synopsis.
Flags
Flags below include inherited options. Types and defaults come from the CLI source. An empty default means no value is configured.
| Flag | Type | Default | Description |
|---|---|---|---|
--check | bool | false | Fetch the latest stable version and report update instructions without changing anything |
--device | string | (empty) | Target device host (hostname, IP, or host:port); 'wendy run' accepts a comma-separated list to deploy one build to several devices (needs a remote build host and --detach). Defaults to $WENDY_DEVICE, then the saved default device |
--json | bool | false | Output in JSON format |
--yes / -y | bool | false | Approve the detected installation's update (required without an interactive terminal) |
Output
Output depends on the operation and selected target. Command behavior and detailed examples.
JSON output
The global --json option requests machine-readable output. The CLI also selects JSON mode when no interactive terminal is attached. Support and payloads are command-specific; this flag does not guarantee a single JSON document for commands that stream logs or invoke build tools. Consult Details before parsing command output.
Exit codes
The CLI entry point returns 0 on success and for its user-cancelled or default-cleared results. Other returned errors exit with 1 and print a diagnostic to stderr. Some operations may terminate through subprocess or signal handling; do not infer application health from the CLI exit code alone.
Common errors
Check argument values and flag combinations against the synopsis above. For discovery, build, port, and readiness failures, see deployment troubleshooting. Command-specific constraints are in Details.

Details
Check the latest stable release, identify the installation method, and update with its owning package manager when supported. Use --check for a fresh read-only check. Unsupported installations receive instructions; the updater never silently creates a second installation.
