ImpactGuard - Detect the blast radius of API changes before you merge

ImpactGuard started from a simple frustration: modern software systems have become so interconnected that even a tiny change can trigger massive unintended consequences. A dependency update, a small refactor, or a configuration tweak could silently ripple through an entire stack — and developers often only discovered the damage after deployment. I built ImpactGuard because I wanted a way to understand the true blast radius of change before things broke in production. The original idea was small: create a tool that could map relationships and warn about risky modifications. But while building it, I realized the real challenge wasn’t just detecting changes — it was making complex system impact visible and understandable. The project evolved from a basic analysis utility into a broader attempt to give developers confidence when shipping software. Every iteration pushed toward the same goal: turning uncertainty into visibility. What inspired me most during the process was realizing how universal this problem is. Whether you’re an indie developer or running large-scale infrastructure, everyone eventually asks the same question: “If I change this… what else will it affect?” ImpactGuard was built to answer that question before production does.
