As answered by people managing Cert Decoder and Devrian.in.
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.
Devrian.in's answer:
DEVRlAN started as an independent developer project focused on making common technical tasks faster and simpler. The goal is to bring useful browser-native utilities into one focused workspace, while keeping privacy and local processing at the center of the experience. It is being developed based on practical developer needs and feedback.
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
Devrian.in's answer:
DEVRlAN is built with Next.js and React using TypeScript. The interface uses Tailwind CSS with CSS variables for the design system, while Framer Motion handles complex UI motion and lucide-react provides the icon system.
Cert Decoder's answer
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
Devrian.in's answer:
DEVRlAN is primarily built for software developers, engineers, and technical users who regularly need quick utilities for tasks such as JSON formatting, JWT debugging, encoding and decoding, UUID generation, regex testing, URL encoding, and hashing.
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.
Devrian.in's answer:
DEVRlAN is designed for developers who want quick, focused utilities without creating accounts, installing software, or sending sensitive data to unnecessary third-party services. Its browser-native workflow keeps common tasks accessible in one place while prioritizing local processing and simplicity.
Cert Decoder's answer
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
Devrian.in's answer:
DEVRlAN is currently an independent developer project and does not have publicly disclosed major customers. The product is available for developers and technical users to use directly.
Devrian.in's answer:
DEVRlAN combines practical developer utilities with a privacy-first, browser-native approach. Tools such as JSON formatting, JWT debugging, Base64 encoding, UUID generation, regex testing, URL encoding, and hashing can be used directly in the browser, with local processing whenever possible and no account or installation required.

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
