As answered by people managing Cert Decoder and GitStreak.
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.
GitStreak's answer:
We don't get in the way. We're only here to support you.
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
GitStreak's answer:
PHP, TailwindCSS, Javascript
GitStreak's answer:
You only receive an email reminder when you haven't committed for the day, so you can maintain your streak.
Cert Decoder's answer
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
GitStreak's answer:
Developers who want to improve their skills by coding daily.
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.
GitStreak's answer:
Ever have that gut-punch moment when you lose a streak?
Yeah, me too.
GitStreak was born from a moment of frustration when I lost my GitHub contribution streak.
Not because I didn’t code, but because I simply forgot to sync.
It was the weekend and without my trusty Deskhub displaying my contribution graph on my office desk, it completely slipped my mind.
While I wouldn’t say I was heartbroken (that’s a bit dramatic), it was definitely a facepalm moment.
As someone who thrives on daily challenges and building new habits, I’ve learned that sometimes we all need a friendly nudge.
That’s exactly what I love about Duolingo — it keeps me accountable with timely reminders.
So I thought, “Why not create the same for fellow developers?”
GitStreak is exactly that: a simple email reminder service that helps you maintain your GitHub streak.
No bells, no whistles — just a friendly ping when you need it.
And the best part?
If you’ve already committed that day, we’ll stay quiet and let you bask in your productivity, keeping your inbox clutter-free.

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
