About DomainCat.app and React-Ionic

In their own words, as submitted to SaaSHub.

DomainCat.app
React-Ionic

DomainCat watches your domains so nothing expires unnoticed. Every 6 hours it checks SSL certificates (including the origin cert behind Cloudflare, which most tools miss), domain registration expiry, DNS, SPF/DKIM/DMARC records, blacklists and security headers, and alerts you by email, Slack,...

Features and specs

What each product offers, as listed by its team.

DomainCat.app 10 features
React-Ionic 5 features
  • Domain Expiry Tracking
    See every domain's registration expiry date and days remaining in one dashboard, with registrar details from WHOIS.
  • Categorization and Tagging
    Organize domains into groups (e.g. one per client) and tags, then filter, search and bulk-edit by group or tag.
  • SSL Certificate Monitoring
    Checks every certificate every 6 hours (issuer, chain, days left) and alerts at 30, 14 and 7 days, then daily if it expires.
  • Origin Certificate Monitoring (Cloudflare)
    Behind Cloudflare, the padlock shows Cloudflare's edge cert. DomainCat also watches your real origin cert so it can't expire silently.
  • Domain Expiry Alerts
    Get warned before a domain registration lapses so a forgotten renewal never takes a site or email offline.
  • SPF / DKIM / DMARC Checks
    Checks email authentication records on every domain and flags missing or weak SPF, DKIM and DMARC.
  • Blacklist Monitoring
    Checks domain and mail-server IPs against major blacklists (Spamhaus, SpamCop and more) and alerts if one gets listed.
  • MCP Server for AI Assistants
    Built-in MCP server, listed in Claude's connector directory. Ask Claude, Cursor or VS Code "what expires this month?" with scoped, revocable access.
  • Slack, Teams & PagerDuty Alerts
    Send alerts to email, Slack, Microsoft Teams, webhooks or PagerDuty. MSPs can also alert the cert owner directly.
  • Free Domain Health Checker
    check.domaincat.app runs SSL, WHOIS, DNS, email security, blacklist and header checks on any domain or IP. No login needed.
  • Cross-Platform Development
    React-Ionic allows developers to build applications that run on both iOS and Android platforms using a single codebase, effectively saving time and resources.
  • React Ecosystem
    Integration with the React ecosystem provides access to numerous libraries and tools, allowing developers to use familiar technologies and streamline the development process.
  • Ionic Components
    Leverages Ionic's UI components that are designed to look and feel native on both iOS and Android, providing a consistent and polished user experience across platforms.
  • Live Reloading
    Features like live reloading and hot module replacement can speed up the development process by allowing developers to see changes in real-time.
  • Community Support
    Being part of the larger React and Ionic communities, developers can tap into extensive community support and resources to help solve issues and improve their applications.

Possible disadvantages

  • Performance Overhead
    Applications built with React-Ionic may experience performance overhead compared to fully native apps, which can be a concern for performance-intensive applications.
  • Learning Curve
    Developers new to the ecosystem might face a learning curve due to the combination of React and Ionic concepts and components.
  • Platform-Specific Customization
    While React-Ionic provides cross-platform functionality, achieving platform-specific look and feel or leveraging native features can require additional customization and work.
  • Ecosystem Dependence
    Reliance on both the Ionic framework and React means developers must stay current with updates and changes in both ecosystems, which can cause maintenance challenges.
  • Bundle Size
    The inclusion of both React and Ionic libraries can lead to larger application bundle sizes, which might impact load times and performance on lower-end devices.

Questions & Answers

As answered by people managing DomainCat.app and React-Ionic.

What makes your product unique?

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.

How would you describe the primary audience of your product?

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.

What's the story behind your product?

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.

Why should a person choose your product over its competitors?

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.

Which are the primary technologies used for building your product?

DomainCat.app's answer

Node.js, PostgreSQL, Docker, and Cloudflare. Hosted on Hetzner. Auth via Auth0, payments via Stripe.

Who are some of the biggest customers of your product?

DomainCat.app's answer

DomainCat is an early-stage product with a growing base of freelancers, small agencies, and MSPs. We're not naming customers publicly at this stage.
