"I built Varen around a problem a lot of developers run into: APIs change quietly, and you usually find out too late. Varen catches those changes automatically across 109 APIs. The core infrastructure is already in place, including source monitoring, diffing, classification, and scheduled scans, and there is a lot of room to grow from here."
