As answered by people managing DomainCat.app and Buffer.
DomainCat.app's answer
DomainCat is built for people who actually manage domains — 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 — 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.
DomainCat.app's answer
Node.js, PostgreSQL, Docker, and Cloudflare. Hosted on Hetzner. Auth via Auth0, payments via Stripe.

I started with Buffer since everyone knows the name. It has been around forever as a scheduler, and now it has a newer GraphQL API that replaced the older, more limited one. - Source: dev.to / 4 months ago
We could have built full autopilot â generate, schedule, post, done. Tools like Buffer and Hootsuite give you scheduling. Some newer tools now offer auto-posting. We deliberately didn't go that route for the first version, and the... - Source: dev.to / 6 months ago
The concept is simple but technically ambitious. We are going to execute a strategy of "dogfooding" (eating our own food). Instead of using third-party tools like Buffer or Hootsuite, we will build a custom distribution engine using the... - Source: dev.to / 9 months ago
