As answered by people managing 9bot and Cert Decoder.
9bot's answer
Large messaging communities often become difficult to manage as they grow. Important information can quickly disappear in fast-moving conversations, while spam and repetitive questions increase the workload for administrators. Automate your WhatsApp group was developed to address these operational challenges by introducing structured automation tools that help maintain organization, reduce manual work, and improve the flow of information inside messaging communities.
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.
9bot's answer
Node.js PostgreSQL WhatsApp libraries Cloud infrastructure services Web dashboard technologies for configuration and management
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
9bot's answer
The platform is primarily intended for community managers, group administrators, content creators, and organizations that rely on WhatsApp groups to share information, coordinate discussions, or distribute updates to large audiences.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
9bot's answer
Many automation tools focus on marketing conversations or customer support flows. Automate your WhatsApp group is designed for community environments where hundreds or thousands of members interact simultaneously. The platform prioritizes moderation, content distribution, and administrative automation, allowing group administrators to manage discussions and information flow without constant manual intervention.
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.

9bot's answer
Automate your WhatsApp group focuses specifically on the operational challenges of managing large messaging communities. Instead of acting as a conversational chatbot, the system provides automation for moderation, commands, scheduled messages, and structured content delivery inside WhatsApp groups. This approach treats messaging communities as dynamic environments that require organization, moderation, and information flow rather than simple automated replies.

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
