# Feature Flags
|
|
|
|
In addition to basic environment variable configuration, LobeChat also offers feature flags to control whether a feature is enabled globally, or to enable or disable features for specific user groups or environments as needed.
|
|
|
|
## Feature Flags Environment Variable `FEATURE_FLAGS`
|
|
|
|
- Type: Optional
|
|
- Description: Used to control LobeChat's feature functionalities. Supports multiple feature flags, using `+` to add a feature and `-` to disable a feature. Separate multiple feature flags with a comma `,` and enclose the entire value in quotes `"` to avoid parsing errors.
|
|
- Default: `-`
|
|
- Example: `"-welcome_suggest"`
|
|
|
|
All features are controlled by the `FEATURE_FLAGS` variable as the sole configuration variable.
|
|
|
|
You can achieve various feature combinations using the above configuration syntax. All feature flags are Boolean values, enabled with `+` and disabled with `-`.
|
|
|
|
<Callout type={'tip'}>
|
|
Attention: Unlike the `OPENAI_MODEL_LIST` variable, the `FEATURE_FLAGS` variable does not support
|
|
the `all` keyword. You need to manually control all feature flags (otherwise, they will adopt
|
|
their default values).
|
|
