As answered by people managing Cert Decoder and StrikeSage.
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.
StrikeSage's answer:
StrikeSage started from a simple frustration: after enough fishing trips, it becomes hard to remember exactly what conditions, lures and methods worked — and what did not. It was built to preserve that history and make it easier to see whether the same patterns appear again.
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
StrikeSage's answer:
Flutter, Dart, Firebase and Firestore.
Cert Decoder's answer
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
StrikeSage's answer:
StrikeSage is built for anglers who want to understand why some fishing trips succeed and others do not. It supports different fishing methods and is especially useful for anglers who regularly track their trips, conditions, spots and tackle.
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.
StrikeSage's answer:
StrikeSage focuses on learning from your own fishing experience instead of relying mainly on generic fishing advice or community data. As you record more catches, misses and blank trips, your personal history becomes more useful for comparing conditions, lure performance and recurring patterns.

StrikeSage's answer:
StrikeSage learns from your own fishing history. It connects catches, missed bites and unsuccessful trips with weather, pressure, spots, lures and fishing methods to help you discover personal patterns. Features like Weekly Hint use that history to show which species and lures best match current conditions based on your own past results.

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
