Git Auto Sync

Keeps a Unity project in step with its git remote.

• When the Editor opens: fetches. If the branch's upstream has new commits, it updates to them. Unpushed local commits are rebased on top, and uncommitted files are stashed and restored. If an uncommitted edit touches a file that also changed remotely, the pull is skipped and the files are listed, so no conflict markers end up in scenes or prefabs.
• When the Editor closes: saves scenes and assets, commits everything in the Unity project folder, brings in anything pushed meanwhile, then pushes. A branch with no upstream is pushed with -u.

If something can't be done safely (a conflict, no network, a failed push), it asks whether to Quit Anyway or Stay Open. Your work is always committed locally first, and an unpushed commit goes up the next time you close.

Install

Embedded: copy the net.lenrui.git-auto-sync folder into the project's Packages/ folder. It becomes part of the project and is committed along with it.

From git: put this folder in its own repository, then in Unity open Window > Package Manager > + > Add package from git URL... and enter the repository URL, for example https://git.lenrui.net/<owner>/git-auto-sync.git. If the package sits in a subfolder of a repository, add ?path=/that/subfolder to the URL.

Requirements

• Unity 2019.4 or newer, and git on the PATH.
• Git credentials that work without typing anything: an SSH key loaded in an agent, or a credential manager for HTTPS. The Editor can't show git's password prompts.
• Library/ must be ignored by git, or the tool refuses to commit. If the Unity project is in a subfolder of the repository, note that Unity's usual /[Ll]ibrary/ pattern only matches next to the .gitignore it's in: keep that .gitignore inside the Unity project folder, or use [Ll]ibrary/ at the repository root.

Menu

Tools > Git Auto Sync

• Enabled: on by default.
• Ask Before Committing on Close: off by default, so closing commits and pushes without a prompt.
• Pull Latest Now and Commit and Push Now: run either half by hand.

Settings are stored per project, per machine.

What gets committed

Only the Unity project folder (the folder containing Assets/). Other files elsewhere in the repository are left alone. Pulls and pushes act on the whole branch as usual.

Commit messages look like Auto-commit from Unity (MACHINE, 2026-11-05 22:27), followed by the list of changed files.
