Duolingo, but to train the code review muscle
lgtmxp is an innovative learning platform designed to sharpen developers' code review skills through gamified exercises. Modeled after language learning apps like Duolingo, it presents coding challenges as pull request (PR) reviews, where users evaluate diffs, flag bugs, or approve changes to earn XP. Covering languages such as Python, React/TS, Go, SQL, and LLM agents, the platform emphasizes real-world debugging scenarios, including tricky issues like off-by-one errors, JWT misconfigurations, and runaway loops. Its browser-based interface requires no signup and tracks progress seamlessly, making continuous practice accessible and engaging. By simulating the review process with immediate feedback and penalties for missed bugs, lgtmxp helps developers hone critical debugging skills in a fun, low-stakes environment. Itβs perfect for individual learners, teams aiming to improve code quality, or anyone looking to deepen their understanding of complex codebases in a hands-on way.
