Command practice
Type Git commands in a guided terminal and see how each command changes the repository.
Computer Science Version Control Lab
Git Simulator for Visual Version Control Practice
Learn Git by running commands and watching the repository change. Visualize the working directory, staging area, commits, refs, HEAD, branches, and commit graph in one interactive OpenLabs workspace.
Git Visualizer
terminal
$ git init
$ git add index.html
$ git commit -m "first commit"
$ git branch feature-ui
Working Directory
Staging Area
HEAD -> main
Commit Graph
main
Working directory
Understand file changes before staging, committing, and moving through a version control workflow.
Commit graph
Visualize commits as repository history so snapshots and branches become easier to reason about.
Branches and refs
Learn HEAD, refs, and branches by watching them update as commands run.
Learn by commanding
A practical Git visualizer for understanding repository state
Git becomes easier when each command has visible consequences. This simulator turns command-line version control into a clear flow across files, staging, commits, refs, branches, and history.
Understand what happens during git init, add, commit, status, branch, and checkout.
See the difference between the working directory, staging area, and committed history.
Learn how HEAD, refs, and branches point to commits in a repository.
Practice version control workflows before using Git on real projects.
Where this lab helps
- Computer science Git practicals
- Beginner software development training
- Version control classroom demonstrations
- Interview and project workflow preparation
How the interactive lab works
Open the simulator, run a Git command, and review the output. The lab updates the repository panel and commit graph so you can understand what changed after each command.
Git Simulator FAQs
What is the OpenLabs Git Simulator?
It is an interactive version control lab where learners run Git commands and see the repository state, staging area, refs, HEAD, and commit graph update visually.
Can I learn Git without installing it?
Yes. The simulator runs in the browser, so beginners can practice core Git concepts before installing Git or working in a real repository.
Which Git concepts does this lab teach?
The lab focuses on command flow, repository initialization, file changes, staging, commits, branches, refs, HEAD, and visual commit history.
Who should use this Git visualizer?
It is useful for students, beginner developers, teachers, and anyone who wants to understand Git workflows through hands-on visual feedback.
Ready to practice Git visually?
