As answered by people managing Adoovy and Cert Decoder.
Adoovy's answer
Adoovy was born out of the frustration of seeing the "black box" of the guest posting industry. Our founders realized that marketers were spending thousands on links that never moved the needle, or worse, penalized their sites. They envisioned a platform that brought transparency and ethics back to content marketing. Adoovy started as a small consultancy helping brands find real voices in their niche and evolved into the robust, data-driven platform it is today—dedicated to the belief that every brand has a story worth telling on the right stage.
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.
Adoovy's answer
Adoovy is built on a reliable and time-tested foundation designed for speed and security. Our core technology stack includes:
HTML & CSS: Used to create a clean, user-friendly interface that works across all devices.
Java: Powers the heavy lifting on the backend, ensuring the platform is stable and can handle large amounts of data.
PHP: Handles the server-side logic and core platform features to keep everything running smoothly.
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:
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.

I used Adoovy mainly because I didn’t want to deal with outreach anymore. Sending emails, waiting for replies, negotiating… it was just too much work. With Adoovy, I could just pick sites and place orders. That’s it....
For one of my SaaS campaigns, I placed 5 guest post orders. All of them were processed within an hour, and the articles went live right around the timeline that was promised. The anchors were used exactly how I...

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
