Langflow supports two storage backends for file management.

  • Local storage: Langflow's default storage backend. Files are stored locally in your Langflow configuration directory. Set LANGFLOW_STORAGE_TYPE=local or leave it unset to use local storage.

  • S3_BUCKET_DIRECTORY: An optional folder path within the bucket where files are stored, such as s3://S3_BUCKET_NAME/S3_BUCKET_DIRECTORY.

For more information, see the AWS documentation.

Google Drive storage is available through the Read File and Write file components, but you cannot use environment variables to configure it.

File storage environment variables​

The following environment variables configure file storage backends for Langflow's file management system:

VariableFormatDefaultDescription
LANGFLOW_STORAGE_TYPEStringlocalSet the file storage backend. Supported values: local (files stored in the Langflow configuration directory) or s3 (files stored in AWS S3). For S3 storage, you must also configure AWS credentials and bucket settings.
LANGFLOW_OBJECT_STORAGE_BUCKET_NAMEStringNot setThe name of the S3 bucket to use for file storage. Required when LANGFLOW_STORAGE_TYPE=s3.
LANGFLOW_OBJECT_STORAGE_PREFIXStringNot setOptional prefix/folder path within the S3 bucket where files will be stored. If not set, files are stored at the bucket root.
LANGFLOW_OBJECT_STORAGE_TAGSJSON objectNot setOptional S3 object tags applied to stored files when LANGFLOW_STORAGE_TYPE=s3. Ignored for local storage. Provided as a JSON map of string keys to string values, such as {"env": "prod", "owner": "data-team"}.
