TackNote is a Mac sticky-note app with a twist: every note pins to the exact thing you're working in — a specific window, browser tab, document, folder, chat, or task — and only appears when you're there. Switch away and it tucks out of sight; come back and it's waiting, right where you left it....
Cert Decoder is a free online tool that helps you decode X.509 SSL/TLS certificates in PEM format. It instantly shows important information like the issuer, expiry date, SAN entries, and fingerprint. All data is processed locally in your browser, so nothing is ever sent or stored elsewhere.

As answered by people managing TackNote.app and Cert Decoder.
TackNote.app's answer
Early one morning I needed to remind myself to push a sandbox site to production, but not at peak traffic, so it had to wait. I had nowhere clean to put the reminder. My only option was a floating sticky note that would get buried under all my open windows the second I started working.
Then it hit me: what if I could tack the note to the push window itself? So, the next time I opened it, the reminder would be right there waiting!
That's TackNote. Every note pins to the exact window, tab, or document it's about, and shows up only when you're there.
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.
TackNote.app's answer
A native macOS app built in Swift and AppKit, with CloudKit for optional end-to-end-encrypted iCloud sync. No web wrappers, no third-party trackers
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
TackNote.app's answer
Mac users who juggle multiple projects, research, or workflows and want quick reference notes tied to context — developers, writers, researchers, students, and anyone tired of a desktop buried in stale stickies or one endless note list.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
TackNote.app's answer
Context-aware — notes follow your windows, tabs, and docs instead of cluttering the desktop - Private by design — end-to-end encrypted, notarized by Apple, no account required - Fair pricing — 14-day free trial (no card), then a one-time $24.99, no subscription - Native Mac app — fast and light, not an Electron wrapper - Plus checklists, voice notes, reminders, projects, and 12 themes.
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.

TackNote.app's answer
Most sticky notes just pile up on your desktop. TackNote pins each note to the exact thing you're working in — a window, browser tab, document, folder, chat, or task — and shows it only when you're there. Switch away and it tucks out of sight; come back and it's waiting. The right note, in the right place, automatically.

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
