I'm part of the team behind Apilytics. We are building an analytics service that is trivial to setup and that is not tied to any single backend framework. Apilytics offers easy to visualize route-specific usage metrics for your API and allows you to see at a glance which of your endpoints get called the most. It can help you throttle specific endpoints or automatically IP-ban bots that are abusing it. We want to be a privacy-first solution from day one, so you'll have full access to all of you raw analytics data at all times, and our middleware client will be completely open-source.
We are currently looking to get interested people to sign up for our free beta. We are looking to develop the initial version closely with our first users! Feel free to ask any questions here and remember to head to www.apilytics.io!
