As answered by people managing Cert Decoder and Madlitics.
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.
Madlitics's answer:
After fighting scattered analytics and inconsistent UTMs across client stacks, I built a form-first approach that preserves attribution at the moment it matters, upon submission. Offering data transparency without the silo, Madlitics makes it easy to see where leads come from, send the data where it belongs, and trust the reports.
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
Cert Decoder's answer
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
Madlitics's answer:
SMB and mid-market marketing teams and agencies that rely on web forms to generate leads, plus RevOps/sales ops who need reliable source data in the CRM. Great fit for teams using WordPress (Gravity, WPForms, Elementor), Webflow, Framer, Typeform, Jotform, and Formstack.
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.
Madlitics's answer:
It’s simpler to adopt, because the data lives inside your submissions and flows through the integrations you already use. You get consistent first-touch attribution, standardized UTMs, and clearer reporting—without heavy setup, custom pipelines, or yet another place to log in.
Cert Decoder's answer
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
Madlitics's answer:
Madlitics is form-first: it writes channel, campaign, landing-page data, and click IDs directly into each form submission, so your existing tools get clean attribution without another dashboard. It standardizes messy UTMs and delivers dependable, first-party data that sales, ops, and marketing can actually use.

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
