We love open-source software, and use the following in the New Relic Node.js agent. Thank you, open-source community, for making these fine tools! Some of these are listed under multiple software licenses, and in that case we have listed the license we've chosen to use.
Remaining code in versions prior to v6.11.0 is licensed under the New Relic agent license agreement. License terms for v6.11.0 and later can be found on GitHub.
