The LaunchDarkly CLI helps you manage your feature flags wherever you are, whether that's in the webapp, your terminal, or your IDE.
With the CLI, you can:
- Evaluate your first feature flag with a guided setup command.
- Onboard your whole team by inviting new members.
- Interact with the LaunchDarkly API using resource & CRUD based commands.
Caution
This package is prerelease and experimental. It should not be used in production and is not supported.
The LaunchDarkly CLI will soon be available for macOS, Windows, and Linux.
Installing the CLI provides access to the ldcli
command.
ldcli [command]
# Run `--help` for detailed information about CLI commands
ldcli --help
LaunchDarkly CLI commands
setup
guides you through creating your first flag, connecting an SDK, and evaluating your flag in your Test environment
Resource commands mirror the LaunchDarkly API and make requests for a given resource. To see a full list of resources supported by the CLI, enter ldcli --help
into your terminal, and to see the commands available for a given resource
To see the commands available for a given resource:
ldcli <resource> --help
An example command to create a flag:
ldcli flags create --access-token <access-token> --project default --data '{"name": "My Test Flag", "key": "my-test-flag"}'
(coming soon!)

- LaunchDarkly is a continuous delivery platform that provides feature flags as a service and allows developers to iterate quickly and safely. We allow you to easily flag your features and manage them from the LaunchDarkly dashboard. With LaunchDarkly, you can:
- Roll out a new feature to a subset of your users (like a group of users who opt-in to a beta tester group), gathering feedback and bug reports from real-world use cases.
- Gradually roll out a feature to an increasing percentage of users, and track the effect that the feature has on key metrics (for instance, how likely is a user to complete a purchase if they have feature A versus feature B?).
- Turn off a feature that you realize is causing performance problems in production, without needing to re-deploy, or even restart the application with a changed configuration file.
- Grant access to certain features based on user attributes, like payment plan (eg: users on the βgoldβ plan get access to more features than users in the βsilverβ plan). Disable parts of your application to facilitate maintenance, without taking everything offline.
- LaunchDarkly provides feature flag SDKs for a wide variety of languages and technologies. Read our documentation for a complete list.
