As answered by people managing PuzzleBuilder and Cert Decoder.
PuzzleBuilder's answer
PuzzleBuilder was created to solve a common problem at events: keeping guests engaged. The idea started with wedding crosswords and grew into a multi-occasion platform supporting seven puzzle types, printable and online play, and events in multiple languages.
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.
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
PuzzleBuilder's answer
Individuals and small teams planning personal or professional events — couples organizing weddings, parents planning birthday parties, teachers creating classroom activities, and HR teams running corporate team-building sessions.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
PuzzleBuilder's answer
Most puzzle tools only offer print output or only online play. PuzzleBuilder does both. It also includes an AI assistant for generating clues and words automatically, supports puzzle content in 8 languages, and is built specifically for events rather than general education or entertainment.
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.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
PuzzleBuilder's answer
PuzzleBuilder combines a visual puzzle designer with online play in a single tool. Users can design, download for print, and publish for guests to play on their phones — all without switching between apps. It supports 7 puzzle types and 13 page sizes, from small cards to large posters.

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
