I have been using prefix for awhile now and issues it identifies are spot on. It has helped me so much in writing better code hy reducing how many calls to our database i was making and help me identify exactly why a few pages where taking so long to load. It is a great product and i am looking forward to seeing what stackify comes up with next.Easy to use and clearly shows you exactly where any issue may be happening

Prefix allows us a quick view of how all of our web apis are behaving and if there any unexpected errors or performance issues we need to address. Using it in conjunction with ReTrace provides even deeper insights without slowing down our production code.Easy to setup and use.

I was tasked with improving the performance on web API calls for a particular project that seemed "slow". After doing the usual performance analysis with Visual Studio, I was reaching for Glimpse and stumbled upon Prefix so decided to give it a go since it required no additional dependencies in the project. Prefix quickly highlighted that there were hundreds of database calls for a single web method call, something that didn't show up in the standard performance analysis tools. This was very obvious from the summary icons so any developers could have identified this. The problem was a component that populated a string lookup from the database in the constructor and was not set to be a singleton in the dependency injector container. Almost everything used this and as the type was resolved/injected it would hit the database each time instead of using a singleton. This simple fix literally cut the web method call time in half making me look like an instant hero!

Prefix is a great tool which has helped pick up issues before I knew there was issues! Its not intrusive and will sit quietly monitoring while I run everything locally, it also has a great UI and makes me look around 43% smarter when its on my second screen :).
