As answered by people managing Joobee.app and Cert Decoder.
Joobee.app's answer
Joobee.app started as a personal tool. Every time I was job hunting as a developer, I tracked applications in Excel, but it was slow, uncomfortable, and easy to abandon once the process got intense. Over time I also lost the bigger picture, how many roles I applied to in previous searches, what worked, and whether I was improving year over year. I realized this isn’t just my problem: people send dozens or hundreds of applications and still have to manage the process like a project. So I built Joobee to make job hunting structured and measurable, first for myself, and then as a product that can help others too.
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.
Joobee.app's answer
Joobee.app is built with React and Next.js using TypeScript, with a Node.js backend and AWS for cloud infrastructure and scalability, with a strong focus on security and privacy (secure authentication, least-privilege access, encrypted data in transit, and best-practice safeguards against common web vulnerabilities).
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
Joobee.app's answer
Joobee.app is primarily for job seekers who apply to multiple roles and want a simple, structured way to stay organized, follow up on time, and improve their chances, especially early career candidates, career switchers, and tech and non-tech professionals who are tired of tracking everything in spreadsheets and scattered notes.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
Joobee.app's answer
People should choose Joobee.app over competitors because it’s built around execution and measurable progress, not vague “AI magic.” It combines a clean end-to-end application workflow with practical AI support and transparent, token-based usage, so you stay consistent, organized, and can actually see what improves your response rate and interviews over time.
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.
Joobee.app's answer
Joobee.app is still early-stage, so we don’t publicly list big enterprise customers yet. Today it’s used primarily by individual job seekers, especially developers and career switchers, who want a structured way to track applications and improve their interview rate.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
Joobee.app's answer
Joobee.app is unique because it turns job hunting into a structured, measurable workflow, not a chaotic pile of tabs and spreadsheets, combining application tracking with practical AI support so you can apply consistently, stay organized, and improve your results over time.

Tracking Joobee.app since Jan 2026.
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
