Safety provides a clear overview of the licenses used across all your dependencies.
To display the licenses in use, run the followng command instead of the usual "safety check" command used to perform vulnerability scans.
// safety license
You can run the following command to get help and a full list of available options.
// safety license --help
License checks require an API key, which you can include either using the "--key" argument or by setting an environment variable using the following command:
// SAFETY_API_KEY (export SAFETY_API_KEY=YOUR_KEY_HERE)
safety licensewill scan the current Python environment for all installed dependencies and report on their licenses.
safety license -r requirements.txtwill report on the packages in the named requirements file.
The default output option is to the screen.
If you wish to ingest or analyze the resulting license report data you can generate a JSON file from the report by adding the
--output jsonargument, as in the example below:
// safety license -r requirements.txt --output json
Another output option is
--output barewhich will print the unique set of licenses that were present in the packages that were analyzed, as in the example below:
// safety license -r requirements.txt --output bare
