When something goes wrong, Aepto alerts you early and clearly explains what happened and which provider to contact. Aepto also helps track domain expenses, visualize spending, assign ROI, organize domains into folders, and customize pricing and provider details when needed. Advanced features include AI-powered domain discovery, domain watch for tracking expiring domains you don’t own, distributed uptime monitoring, and customizable white-labeled status pages with incidents and maintenance updates. Designed for businesses, agencies, and teams that rely on domains for live websites, email, and APIs, Aepto focuses on proactive monitoring and clarity—so nothing breaks silently and small issues don’t turn into bigger problems.
