As answered by people managing Cert Decoder and DemoBot.dev.
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.
DemoBot.dev's answer:
Writing code has completely changed, the idea of reviewing every line of code is dying. Automation tests and AI code review is going to cover the quality of code itself and prevent regressions. What stakeholders will really care about is "Did this code satisfy requirements". We have encountered this personally in our own development work, results matter much more than how we got to those results.
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
DemoBot.dev's answer:
We used Claude and our own proprietary AI Agent platform as our primary assistants. It's implemented in TypeScript and deployed on AWS with MongoDB for persistence. We leverage Lambda MicroVMs for running customer code, ensure secure isolation for both our security and yours.
Cert Decoder's answer
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
DemoBot.dev's answer:
Product Managers, Developers, Marketers - anyone who wants to see UI changes sooner.
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.
DemoBot.dev's answer:
DemoBot is quick and easy to setup and "just works". For most apps just install the Github App. For Apps requiring some additional config, just drop our prompt into your coding agent and it'll take care of the rest.
Cert Decoder's answer
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
DemoBot.dev's answer:
Most agents checking your PRs are reviewing code or running tests. DemoBot isn't for verifying how something gets built, its for the human that requested the work to verify what got built.

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
