Hey there! I'm excited to share something I've built that I think will make your life a lot easier if you work with domains and web infrastructure. After years of constantly switching between different tools to check DNS records, WHOIS information, and SSL certificates, I decided to create DNS Checker Pro - a Chrome extension that puts all this information at your fingertips.
Why I Built DNS Checker Pro
As a developer, I found myself constantly needing to look up domain information, and the process was always the same: open multiple tabs, visit different websites, copy-paste domain names... you know the drill. I thought, "There has to be a better way." That's when I decided to build DNS Checker Pro - to make domain analysis as simple as a single click.
What Can It Do?
Let me show you what DNS Checker Pro can reveal about any website with just one click:
š Complete WHOIS Information
- Registration and expiration dates
- Registrar details
- Name servers
- Administrative information All without leaving your current tab!
š Comprehensive DNS Records
- A and AAAA records for IPv4 and IPv6
- MX records for email configuration
- CNAME records for aliases
- NS records for name servers
- TXT records (including SPF and various service verifications)
- SOA records for zone information
š Detailed SSL Certificate Analysis
- Validity periods
- Issuer information
- Certificate algorithms
- Complete certificate chain including intermediate and root certificates
- Expiration monitoring
Real-World Application
Let's take ui.com as an example. With one click, DNS Checker Pro instantly shows you:
- Their complete email server setup through MX records
- Various service integrations through TXT records (Stripe, Docker, Facebook, etc.)
- SSL certificate details and expiration dates
- Full DNS configuration
This kind of instant access to information is invaluable whether you're troubleshooting, doing research, or just curious about how different websites are set up.
Ready to Try It?
I built DNS Checker Pro to be intuitive and straightforward - just install it from the Chrome Web Store and click the icon whenever you want to analyze a domain. You can get it here: DNS Checker Pro
Here are some ways I personally use DNS Checker Pro:
- Quick domain health checks
- Verifying DNS propagation after making changes
- Checking SSL certificate expiration dates
- Investigating email delivery issues through MX records
- Analyzing website configurations for technical research
I'm constantly working on improving DNS Checker Pro based on user feedback. I believe tools should evolve with their users' needs, so if you have any suggestions or feature requests, I'd love to hear them!
DNS Checker Pro is my solution to a problem that many of us in the web development and IT world face daily. It's designed to be powerful enough for professional use while remaining simple enough for anyone interested in learning about web infrastructure.
Give it a try, and let me know what you think! You can find DNS Checker Pro on the Chrome Web Store: DNS Checker Pro
