A saved snapshot of your project at a specific point in time, like a checkpoint in a video game.
A commit is a saved snapshot of your entire project at one moment. Think of it like the save function in a video game—it captures the exact state of everything and lets you restore it later.
Each commit includes the changed files, a message describing what changed, who made the change, and when. Git creates a unique ID (hash) for each commit so you can reference it later. Commits form a chain—each new commit knows about the one before it, creating a complete history stored in a repository on GitHub.
Commits are essential for tracking progress, reviewing what changed, and reverting mistakes. CI/CD pipelines run tests on every commit. Claude Code creates commits with meaningful messages. Deployment platforms auto-deploy from new commits. Good commit messages make it easy for teammates (and your future self) to understand why each change was made.
