Git is a version-control tool that records every change made to a project’s code. Each save, called a commit, captures what changed, who changed it, and why, building a complete timeline you can step back through at any time.
Think of it as an unlimited undo button with a memory. A word processor lets you undo your last few keystrokes; Git keeps every meaningful version of a project forever. If a change introduced a bug last Tuesday, you can see exactly what was different and return to the working version in seconds. Nothing is ever truly lost. Better still, every commit carries a short message explaining why the change was made, so the history reads almost like a diary of the project.
That diary is also how a team avoids chaos. When two people edit the same file, Git can usually weave their work together on its own, and when it cannot, it points at the exact lines that clash and asks a human to decide. The result is that several developers can move fast on the same code without quietly overwriting each other.
Git also lets many people work on the same code without stepping on each other. Each developer creates a branch, a private copy where they build a feature, then combines it back through a merge once it is ready. All of this history lives in a repository, which can sit on a developer’s machine and be shared with the team. And because every copy holds the full history, the project is never trapped in one place.
At TopDevs we manage all client code in Git, so every change is tracked, reversible, and safely shared across the team instead of living on a single laptop.
