As answered by people managing DailyToolkit.app and Cert Decoder.
DailyToolkit.app's answer
DailyToolkit.app was built out of frustration with scattered, ad-heavy single-tool websites that require signups for basic utilities. The goal was to consolidate the most commonly needed everyday tools like calculators, converters, generators, and text utilities, into one fast, privacy-respecting site.
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.
DailyToolkit.app's answer
Next js, Javascript, Tailwind css
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
DailyToolkit.app's answer
Students, developers, writers, and everyday users who need a quick calculator or text/data utility without creating an account, for example, students calculating GPA, developers formatting JSON or generating READMEs, and writers counting words or characters.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
DailyToolkit.app's answer
Most competing tool sites gate features behind accounts, show heavy ad interstitials, or limit free usage. DailyToolkit.app keeps every tool free and unlimited, loads fast with lightweight pages, and processes everything client-side for privacy. so there's no waiting, no popups, and no data retention.
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.
DailyToolkit.app's answer
No customers, free to use for everyone
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
DailyToolkit.app's answer
It bundles 40+ tools into one fast, ad-light site instead of forcing users to bounce between single-purpose tool sites. Every tool runs entirely in the browser. No data is sent to a server, no signup is required, and there's no usage limit on any tool.

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
