I built Commitea: Git and GitHub explained in Spanish, with an interactive visualizer

When I started programming, Git was hard for me — like anything new is at first. Over time I noticed something: most of the best resources for learning it are in English. And for a lot of people just starting out, that's one more obstacle they shouldn't have to deal with. So in my spare time I built the thing I wish I'd had back then: Commitea . What is it? Two pieces, designed to complement each other: An open source repo with the full documentation in Spanish — from what a commit actually is, to how to get yourself out of trouble with rebase , a cherry-pick , or a push you regret. Every entry follows the same format: the concept in one sentence, a real example with commands, and "how this breaks" (the typical mistake people make). A web app with an interactive visualizer ( commitea-web.vercel.app ) where you type real Git commands and watch, live, what happens to the branch/commit graph. It doesn't touch any real repo — it's an in-memory simulator, but the engine actually replicates real Git behavior: fast-forward vs. merge commit detection, history rewriting on rebase, blocking a branch switch when you have uncommitted changes (just like real Git does), etc. What's in it right now 7 built-in scenarios you can run with one click and watch play out step by step: branch + merge, fast-forward, rebase, cherry-pick + reset --hard, fixing a commit made on the wrong branch, several branches merging in sequence, and stashing changes. Full command support : branch , checkout , commit , merge , rebase , cherry-pick , reset --hard , stash (with an edit helper command to simulate uncommitted changes, since the simulator has no real filesystem), status , and log . Site-wide search (⌘K), powered by Pagefind, indexing only the actual article content — not nav or boilerplate. A feedback widget on every article ("was this helpful?") that stores vote counts in Redis, so I know which content needs work without guessing. Light/dark mode , respecting system preference by default. A ch
