gitjoin

What is gitjoin?

gitjoin is an open-source command-line tool that turns many Git repositories into one virtual monorepo. It joins independent repositories into a single, navigable working tree without rewriting history, without submodules, and without forcing teams to consolidate their codebases.

Why a virtual monorepo?

A virtual monorepo gives you the developer-experience benefits of a monorepo — one tree to search, build, format, and review across — while each repository stays independently versioned and owned. Polyrepo on disk, monorepo at the workbench.

Features

• Minimal configuration — one small config file per virtual tree.
• No history rewrites: original repositories remain untouched.
• A lightweight alternative to Git submodules and subtree merges.
• Written in Go; runs on Linux, macOS, and Windows.
• Free and open source under the MIT license.
