What Is Git? A Plain-English Explanation for Builders
A save-and-history system for your project, remembering every version so you can compare or return to any of them. Why your AI builder connects to it automatically, and what a commit actually is.
Quick answer
Git is a system that records a snapshot of your project every time you save a meaningful change, and keeps every past snapshot around so you can look at, compare or return to any of them later. It's not a backup service and it's not the same thing as GitHub: Git is the underlying mechanism, running entirely on the machine or platform doing the work, and GitHub is a separate website that hosts a copy of that history online. Lovable, Base44 and Bolt.new all connect to GitHub with one click, committing and pushing your changes automatically, which is why most people using an AI builder never type a single Git command by hand.

The one-sentence version: a save-and-history system, not a backup service
An ordinary file save overwrites what was there before, leaving one current version and nothing else. Git works differently: every time you save a meaningful change, it keeps that version too, alongside every version that came before it, in order. Nothing gets thrown away by default. This is what makes Git a history, not just a save button, the difference between "the file as it is right now" and "the file as it's been at every point you chose to record."
A file "Save" vs. a Git commit
An ordinary save
Overwrites what was there:
One current version, nothing else kept
A Git commit
Adds a new snapshot to the history:
Every past version stays inspectable, nothing lost

Where you'll actually see this: commit, push, pull, branch, repository
Five words cover almost everything you'll run into, whether or not you ever type them yourself. A commit is one saved snapshot with a short message describing what changed. A push sends your local commits to GitHub. A pull brings changes from GitHub back down to where you're working. A branch is a separate, parallel line of commits you can experiment on without touching your main project. A repository, or "repo," is the project itself, its entire history in one place. Recognising these helps when reading your project's history on GitHub's own site, even if your AI builder handles the actual commands.
Why your AI builder connects to GitHub automatically
Lovable, Bolt.new and Base44 all offer a one-click "Connect to GitHub" option, and each treats it slightly differently in practice, covered in full in this site's own guide to Git and GitHub basics for AI-built projects. The underlying reason every platform offers it is the same: a connected repository gives you a real, inspectable history independent of the builder itself, something your platform's own preview session doesn't guarantee survives forever on its own.
The one thing this replaces: your builder's own revert button
Most AI builders include a revert or "restore previous version" feature, and it genuinely works for what it's built for, covered in this site's own guide to breaking vibe-code loops. A connected GitHub repository does something more precise: every pushed change is its own separate, inspectable commit, not a single remembered checkpoint. When a specific change three or four prompts back turns out to be the actual problem, a real Git history lets you look at exactly what changed in that one step, not just jump back to the most recent working state.
Not every project needs to think about this
A quick prototype you're not planning to keep, or a Claude Artifact you're using for a single, disposable task, gets nothing from a Git history that matters for that use. Git earns its keep once a project is real enough that losing a specific past version, or needing to see exactly what changed and when, would actually cost you something. For anything past a first quick experiment, connecting your builder to GitHub costs one click and nothing else, which is why it's worth doing by default rather than only once something's gone wrong.

Frequently asked questions
What's the difference between Git and GitHub?
Git is the underlying system that records your project's history, and it works entirely on the machine or platform doing the work, with or without an internet connection. GitHub is a separate website that hosts a copy of that history online, so it can be viewed, backed up or shared from anywhere. Git is the mechanism; GitHub is one place, the most common one, to keep a copy of what it records.
Do I need to type Git commands if my AI builder connects to GitHub automatically?
Not to get the benefit. Clicking Connect to GitHub inside Lovable, Base44 or Bolt.new does the actual Git work for you, committing and pushing changes automatically as you build. Knowing roughly what a commit is still helps once something breaks and you want to understand what changed, but typing the commands yourself isn't required.
What is a commit, really?
A commit is one saved snapshot of your entire project at a specific point, along with a short message describing what changed. Git keeps every commit you've ever made, in order, which is what lets you compare any two points in your project's history or return to a specific one, not just the single most recent save.
What's a branch, and will I ever need one?
A branch is a separate, parallel line of commits you can experiment on without touching your project's main history. Most solo builds on Lovable, Base44 or Bolt.new never need one directly, since the platform's own preview already gives you a safe space to try changes. Branches become genuinely useful once more than one person is working on the same project at the same time.
Can I use Git without GitHub?
Yes. Git itself needs no internet connection and no external service, it can track a project's history entirely on one machine. GitHub is popular because it adds hosting, backup and collaboration on top of what Git already does locally, not because Git depends on it to function.
What happens to my Git history if I disconnect my builder from GitHub?
The commit history already pushed to GitHub stays exactly where it is, since GitHub is a separate, independent copy. What stops is any further syncing: new changes you make after disconnecting won't be recorded there until you reconnect. Check the specific behaviour of your own platform before assuming, since exact reconnection steps differ.
