Find and recommend an alternative to New Relic for Application Performance Monitoring

[arbrandes]

The use of the source-map devtool in the default production config (imported here) has been identified as a way to generate stack traces for New Relic's APM solution.

However, this raises the question of finding an open source alternative that serves the same purpose, via the same source-map devtool, testing it, and then recommending it to the community at large.

@jmbowman has put together a great list of potential alternatives:
