GitQuest2025 · gitquest.dev · ▲187Hey HN, I built Git Quest, it reads your public GitHub history and turns it into an idle RPG character. How it works: - Your most-used language determines your class (TypeScript → Paladin, Python → Sage, etc.) - Commits generate Power and XP - Your character auto-battles dungeons while you code – no active play needed - Enemies drop loot across 5 rarity tiers - Live leaderboard ranks developers It only reads public GitHub data. I built it because I wanted something that rewards coding consistency without being another "streak" tracker. The idle mechanic means prolific coders naturally…

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…

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
