A Cryptic Hunt Website
Hi HN!, We're a group of High Schooler's who have made a website for an international cryptic hunt we have been organizing. Everything has been built from the ground up and has been open sourced. We'd love feedback on our work. And if it interests you, feel free to register and try a level or two! URL: https://halocrypt.com/ Source: https://github.com/halocrypt We're particularly proud of our frontend, since we have used a framework we built ourselves!

A Cryptic Hunt Website is a platform for an international cryptic puzzle competition built and open-sourced by high school students. Participants register to solve encrypted challenges across multiple levels. The site features a custom-built frontend framework developed entirely by the team, distinguishing it from typical puzzle platforms. The entire codebase is publicly available for review and contribution.

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
