As answered by people managing SuppDoc.io and Cert Decoder.
SuppDoc.io's answer
SuppDoc.io was built out of frustration with supplement advice that is either hype ("this pill fixes everything") or locked behind a paywall, while the boring-but-important parts get skipped: what you shouldn't combine, the dose that was actually studied, and what's just marketing. The goal is a free, honest tool that grades the evidence transparently, links the studies, says when a supplement isn't worth it, and never sells its own pills.
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.
SuppDoc.io's answer
SuppDoc.io is built with Next.js (React) and TypeScript, uses Supabase (PostgreSQL) for its database and authentication, and is 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
SuppDoc.io's answer
Health-conscious adults who take (or are considering) supplements and want evidence over hype: people optimizing sleep, energy, focus, stress, or training, those making sense of bloodwork, and anyone who already takes several supplements and wants to check them for interactions, redundancies, and correct dosing. It's built for beginners and the supplement-curious alike — no clinician or signup required.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
SuppDoc.io's answer
Most supplement advice online is either hype or paywalled. SuppDoc.io is free, needs no account or clinician, and grades every recommendation by the actual evidence, linking the clinical studies so you can check them yourself. Unlike practitioner platforms such as Fullscript, you don't need a provider to use it; and unlike static review sites, it personalizes a full stack to your goals and then audits it for interactions, redundancies, and dosing. It also has no house brand to push.
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.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
SuppDoc.io's answer
SuppDoc.io is free and stays neutral: it doesn't sell its own pills, so there's no incentive to push any specific product. Every recommendation is evidence-graded, and the number of real clinical studies behind each ingredient links straight to PubMed so you can verify it yourself. It's also one of the few tools that tells you when you don't need a supplement, and that audits a stack you already take for interactions, redundancies, and dosing.

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
