Questions & Answers

As answered by people managing Cert Decoder and FolioDoc.

What's the story behind your product?

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.

FolioDoc's answer:

I watched professionals waste hours every week sending reminder emails for missing documents. Tax season is the worst — accountants chase dozens of clients for the same paperwork every year. I built FolioDoc to automate that entire workflow: create a checklist, set a deadline, and let the system handle the reminders.

Which are the primary technologies used for building your product?

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

FolioDoc's answer:

Django and Django REST Framework on the backend, Next.js with TypeScript on the frontend, PostgreSQL for the database, Celery with Redis for background jobs and email scheduling, ClamAV for antivirus scanning, and nginx as the reverse proxy. Hosted on Hetzner in Germany.

How would you describe the primary audience of your product?

Cert Decoder's answer

certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.

FolioDoc's answer:

Accountants, tax advisors, HR teams, consultants, freelancers and law firms — anyone who regularly collects documents from clients, employees, or partners and is tired of chasing people over email.

Why should a person choose your product over its competitors?

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.

FolioDoc's answer:

Simplicity. Competitors like Content Snare and Clustdoc are powerful but complex — they take hours to set up and overwhelm clients with features. FolioDoc takes 2 minutes to create a request and your client needs zero training to use it. Plus, every upload is scanned with ClamAV antivirus, and the whole platform is GDPR compliant and hosted in Germany.

Who are some of the biggest customers of your product?

Cert Decoder's answer

certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.

What makes your product unique?

FolioDoc's answer:

Zero friction for recipients. They click a magic link, see a checklist of what's needed, upload their files, and they're done. No account creation, no passwords, no app to install. Most document collection tools force both sides to create accounts — FolioDoc only requires the sender to have one.

    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
