As answered by people managing Whatayarn and Cert Decoder.
Whatayarn's answer
Whatayarn started after watching Australian podcasts struggle every week to collect listener voicemails. Hosts were asking fans to record in phone voice memos, attach files to emails, keep an eye on file sizes, and hope everything arrived. Whatayarn replaces all that with a single shareable link that slots into show notes or socials so listeners can tap, talk, and send.
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.
Whatayarn's answer
Whatayarn is built with a modern web technology stack using Next.js, deployed on a global cloud platform for speed and reliability. It is designed for high performance, accessibility, and mobile first usage so your voicemail page loads fast and works on any device your listeners use, letting anyone send you a voice message straight from their browser.
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
Whatayarn's answer
The primary audience is independent podcasters and small podcast teams who run listener Q&A, hotlines, or community segments. Many are creators who want call ins on their show without dealing with custom dev, complex tools, or managing raw audio files by hand.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
Whatayarn's answer
Whatayarn focuses on the podcaster workflow end to end. Listener experience is frictionless, creators get formatted MP3s by email plus a simple inbox, and pages look good on mobile out of the box. Pricing is simple, there is a generous free tier, and because it is indie built the roadmap stays close to what creators actually ask for.
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.
Whatayarn's answer
100+ podcasters, plus wedding and event hosts and small businesses using Whatayarn to collect stories, testimonials, and voice feedback from their audiences.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
Whatayarn's answer
Whatayarn is voicemail built specifically for podcasters. Instead of sending listeners to clunky voice memo workflows, you give them one branded link in your show notes. They tap, record or upload a message, and you get a clean MP3 with context straight to your inbox and dashboard. No apps, no logins, no fiddly setup.

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
