As answered by people managing Cert Decoder and Restora.cc.
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.
Restora.cc's answer:
Restora started from a simple, uncomfortable question: if someone deleted your Notion workspace right now, could you actually get it back — relations, rollups, and all? Most backup tools couldn't honestly answer yes. Restora was built to close that gap: not just backing up data, but proving it restores faithfully, with the same relational integrity you built with.
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
Restora.cc's answer:
NestJS, Node.js, Notion API, Google Drive API, S3, TypeScript, React
Cert Decoder's answer
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
Restora.cc's answer:
Teams and individuals running critical work in Notion — databases with relations, rollups, and workflows they can't afford to lose. Particularly founders, ops teams, and agencies who've been burned by an accidental delete or a messy migration and want real disaster-recovery guarantees, not just a backup button.
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.
Restora.cc's answer:
Most Notion backup tools give you a JSON dump and hope it works when you need it. Restora proves it works before you ever need it — free, automatic drift detection catches what changed since your last backup, and a one-click restore rehearsal shows you the exact recoverability verdict. It also handles what other tools miss: multi-level rollup chains, self-referencing relations, and full page hierarchies, not just flat database rows.
Cert Decoder's answer
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
Restora.cc's answer:
Restora doesn't just download your Notion workspace — it verifies the backup actually restores. Most backup tools stop at "we have a copy." Restora runs a free Drift Audit and Restore Rehearsal that confirm your data comes back exactly as it was: relations reconnected, rollups recomputed, views intact. It's built store-nothing — your backup goes straight to your own Google Drive or S3, never sits on our servers.

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
