DomainCat is a clean, purpose-built SSL and domain monitoring platform for infrastructure professionals and MSPs who manage certificates on behalf of clients. Unlike generic uptime tools that bolt on SSL checks as an afterthought, DomainCat is built around the MSP workflow โ track certs you own, certs you host for others, and alert the actual cert owner when action is needed.
StackChanges specializes in monitoring server security and detecting critical changes that could impact your business. Our platform offers features such as uptime monitoring, DNS monitoring, and SSL certificate tracking, ensuring that you receive instant alerts for vulnerabilities and unauthorized access. With detailed insights into port vulnerabilities and performance metrics, StackChanges empowers businesses to respond proactively to security threats.

StackChangesDomainCat.app's answer
DomainCat is built for people who actually manage domains โ not just own one or two. It gives you a single place to track domains across any registrar, monitor expiration dates, and get alerted before anything slips through the cracks. No bloat, no upsells, just clean domain visibility.
DomainCat.app's answer
Freelancers and agencies managing domains for clients, MSPs tracking large domain portfolios, and individuals who own more domains than they can keep in their head. Anyone who has ever let a domain expire by accident is the target user.
DomainCat.app's answer
DomainCat was built by a solo developer who kept losing track of domains spread across multiple registrars. The existing tools were either locked to a single registrar or way too complex. So he built the tool he actually wanted to use โ and decided to ship it.
DomainCat.app's answer
Most domain management tools are either built into a registrar (so they only show you their domains) or are enterprise-priced spreadsheet replacements. DomainCat is registrar-agnostic, affordable, and designed to be immediately useful without a setup headache. MSPs and power users can manage unlimited domains without paying enterprise prices.
