What’s your biggest pain point around API changes?

Hi everyone, I'm Byron, founder of Diffly. After seeing too many projects break because of unexpected API changes, I decided to build Diffly—an app that monitors your endpoints, detects schema and behavior changes, and guides you to a fix. Diffly's launch is just a day away, and I'd love to hear from this community: How do you currently handle API drift? What tools or processes do you wish you had? Your feedback will help shape our roadmap and ensure Diffly truly solves real problems.
