ConfigCat

We could easily connect it to our .NET Core backend. Works like a charm on Linux which in case of an early stage startup means a lot. This way we can run on $5 VPSes instead of an expensive cloud based or Windows VPS.

Most of the people in our team were backend developers when we started building ConfigCat (configcat.com). So it was given that at first we tried using already known technologies. It turned out that we are having a hard time presenting dynamic data or adding inline editing functionality. At first we built our application using ASP .NET Razor Also wanted to make sure our web app is capable of being responsive even if we didn't have the complete picture at that time of what functionality we'd like to have. We selected Angular + .NET Core because Typescript is bit familiar for us coming from the typed C# world and we can still have our REST API written using familiar technology. Also .NET Core runs and scales easily on cheap Linux VPSes. It's great that we could still benefit from our experience building enterprise level applications building a cost efficient service that scales.
