GitGuessr
I built this game as a playful way to train code reading skills. You're dropped into a random location in a real GitHub repo where some lines code are hidden. The goal is to pick up clues from the surrounding code and fill in the missing lines as quickly as possible. It currently has curated game content for Python, TypeScript, JavaScript (by most metrics the top 3 languages on GitHub). I had the idea when it dawned on me that reviewing and understanding code spat out by an LLM is a key skill for the AI era. (I sincerely hope you're critically reviewing what your favorite LLM is serving…

What it does
GitGuessr is a new unique game that drops you into a random location in a real GitHub repo where some lines of code are hidden. Your goal is to understand the codebase and fill in the missing code as quickly as possible. Play well-balanced games in Python, TypeScript, JavaScript (the top 3 languages on GitHub). Or create your own code maps for the community from your favorite languages or favorite repos.
Drop into a random location in a real GitHub repo. Test your code reading skills. Fill in missing lines. Python one-liners from popular libraries - perfect for beginners or for a casual challenge. Immediate context makes it possible to get the answer without browsing much code. Challenging for Python coders with a decent amount of experience. Includes locations that require knowledge of advanced language features or of the standard library. Often requires reading and understanding a chunk of surrounding code. GitGuessr is a game that tests your code reading skills. You're dropped into a random location in a real GitHub repo where some lines of code are masked. Your goal is to understand the…from gitguessr.com

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…

GitHits beta 0.9Jun 2026 · githits.com · ▲181It has been almost 10 years since I started the opencv-python packaging project. Scaling it to more than 100 million downloads as a side project showed me how much ease of installation and proper package distribution matter to users. It gave the computer vision ecosystem a noticeable boost. Now I have a new idea that I hope can help even more people across the broader software engineering world. A while ago, I realized I kept giving the same advice to teammates and friends when they ran into a programming issue they couldn't easily solve: go to GitHub and look at how others solved it. There…
- IBI built a tool to find devs based on code, not LinkedIn titles2025 · gitmatcher.com · ▲86
Hey HN After years working in software engineering and helping with hiring, I noticed a frustrating pattern: Companies often rely on résumés and LinkedIn titles to find developers instead of looking at what they've actually built. So I built GitMatcher. It analyzes GitHub profiles to surface developers based on: Their public repos Commit history Originality and usefulness of code Patterns that show consistency and real skill No keywords. No job titles. Just code. GitMatcher is useful if you're: - A recruiter tired of resume roulette - A founder looking for a technical co-founder - An OSS…
GitByBit — Git course integrated into VSCode and CursorJan 2026 · gitbybit.com · ▲13Hi folks! My name is Alexander Shvets. People know me best as an admirer of raccoons and the creator of Refactoring.Guru Today I'd like to show you the project I've been working on for the past two years: https://gitbybit.com It's a Git course that runs inside your code editor (VS Code, Cursor, and friends), so you learn Git by using it in real dev environment. It's well-designed and illustrated. ## Who is it for? The course will be most helpful for three groups of people: - Developers who “use Git” but mostly as a black box. You know a few commands, but you want to actually…
- CACoderoulette, a pair programming game for developers2016 · ▲42
Hello everyone, We just launched a side-project we have been building over the last couple of months -- Coderoulette is a pair programming game for developers, like a Chatroulette for hackers. We match developers in real time and give them coding challenges they have to solve doing pair programming using a collaborative IDE and video conference. You can check it out here: https://www.coderoulette.com/ We also published an article explaining how we built it. I'd love to hear your feedback.…

Talanoa▲338Hi 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…

Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
