As answered by people managing Cert Decoder and RoomPin.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.
RoomPin.in's answer:
Finding a place in an Indian city means joining ten Telegram and Facebook groups, seeing the same photos reposted, and never knowing how far a room is from your office. We built RoomPin to replace that with one real map, every room, flat, PG and flatmate near where you work, from verified accounts, with rent and fees upfront, and matching by budget, location and lifestyle so the search actually fits you.
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
RoomPin.in's answer:
Node.js, Express and MongoDB; a map-first vanilla-JavaScript web app; native iOS and Android via Capacitor; Google Maps and Places API; Firebase Cloud Messaging for push; Cloudinary for images; hosted on AWS with Nginx.
Cert Decoder's answer
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
RoomPin.in's answer:
Working professionals and students relocating within or into Pune, especially the Hinjewadi IT corridor (Wakad, Baner, Balewadi, Aundh), searching for rooms, flats, PGs or compatible flatmates near their office.
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.
RoomPin.in's answer:
Instead of scrolling ten Telegram and facebook groups or list portals full of reposted photos and prices that change on the call, RoomPin puts everything on one clean map near where you actually work, verified posters, fees upfront, ranked matches by budget, location and lifestyle, plus flatmate compatibility. You find the right place and the right person, faster.
Cert Decoder's answer
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
RoomPin.in's answer:
It's map first: every room, flat, PG and flatmate shows up on a real interactive map near your workplace, not buried in chat groups, with verified posters, rent and fees shown upfront, and matches ranked by budget, location and lifestyle. It even helps you find a compatible flatmate to split rent, not just a spare bed.

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
