As answered by people managing Rupt and Cert Decoder.
Rupt's answer
Rupt is the most accurate solution built for the specific purpose of growing revenue without annoying users. Competitors have nowhere near the accuracy or effectiveness of Rupt.
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.
Rupt's answer
Most SaaS products will see a 5% - 20% increase in revenue after integrating Rupt. SaaS products with seat-based pricing, digital consumables (stock images, videos, etc.), and products with free trials or unlimited clauses in their plans also see huge gains from preventing fraud and abuse with Rupt.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
Rupt's answer
Rupt was born out of necessity. The founder struggled to generate revenue in the previous company because account sharing was rampant. After trying all existing solutions in the market to no success, Ahmed decided to build a real working solution. Rupt was born and quickly reached many companies, generating millions of new net revenues for clients.
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.

Rupt's answer
Rupt is a comprehensive solution for detecting and preventing fraud draining SaaS revenue. Unlike many tools Rupt detects, monitors, and stops fraud with immediate impact on revenue on auto-pilot with a customizable solution.
Rupt's answer
Rupt uses machine learning to analyze user behavior and available signals for browser fingerprinting, device identification and person detection. Many of the algorithms are intellectual property and cannot be revealed. However some signals are exposed to customers after signing up.
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

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
