As answered by people managing IP-API.com and Cert Decoder.
Cert Decoder's answer:
I built certdecoder.com over the weekend for my own needs. Sometimes in my work, I need to verify and check certificate details.
Cert Decoder's answer:
certdecoder.com was built using just JavaScript and HTML—simple, fast, and with all processing happening locally in your browser, so no certificate data is sent to any server
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
Cert Decoder's answer:
Simple, fast, and reliable. Some similar tools can’t even decode basic certificates. I rigorously tested my tool with many real-world certificates and covered several edge cases where competitors fall short.

Free public geo APIs do not love datacenter traffic. My first instinct was to use ip-api.com — it’s the go-to for “what country is this IP” lookups and has a generous free tier. Hooked it up, ran the direct profile, got a clean response.... - Source: dev.to / 3 months ago
The original version used http://ip-api.com — plain HTTP. On a cloud server, that traffic is unencrypted and could be intercepted and spoofed. I switched to https://ipinfo.io which supports HTTPS on the free tier. - Source: dev.to / 6 months ago
In this example, I'll process messages based on their originating IP address. Multiple threads will enrich them with location data fetched from the public API at https://ip-api.com/. - Source: dev.to / 8 months ago
Why? Because I built certdecoder.com and couldn’t find a decent place to submit it. So I said screw it — I’ll build my own. With blackjack and hookers. - Source: dev.to / over 1 year ago
