BI for developers. Developers run many organizations and teams now, but most Business Intelligence-ish tools are either built for business people (Tableau, Domo) or for marketing (all analytics products, specifically GA).
I feel like there's a big opportunity for a tool/tools that are installed in apps as a package and then customized from there. Many teams build a version of this in house (Instacart open-sources theirs), and I think it should be a product.
New Relic was the inspiration for this idea. I shouldn't have to put my data into NR to get value, the data is already either in my app's DB or running through my app. There are actually a lot of reasons why having it be installed and within the app itself is ideal, opens up many doors that are closed by NR. I want something that starts with that as a first principle and then figures out the way to best execute it.
I'm considering writing a web analytics for developers course/e-book. Out of the box GA is good and quite simple to implement but getting anything non-trivial out of it can be very cumbersome - if anyone is interested would love to hear your enthusiasm.
Not 100% what you are looking for, since you specify "installed in apps as a package", but we are using https://redash.io/ and love it. They are open source and very easy to run ad-hoc queries, save/schedule queries and alerts, and build dashboards.
