As answered by people managing IdeaRoast and Cert Decoder.
IdeaRoast's answer
It was born from the founder's own need to filter through a constant stream of side-project ideas using a professional, automated "roast" rather than biased human feedback.
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.
IdeaRoast's answer
Idearoast is built with a modern web stack consisting of Next.js and Supabase, deployed on Vercel.
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
IdeaRoast's answer
The tool is designed for indie hackers and solo founders who need an objective "kill switch" for their ideas before investing time or money.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
IdeaRoast's answer
It offers a frictionless, no-account-needed experience with low one-time fees and crypto payment options.
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.
IdeaRoast's answer
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
IdeaRoast's answer
Idearoast uses a multi-agent panel (Market, Tech, Finance, Timing) to provide "brutally honest" friction that standard, polite AI lacks.

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
