## What it is
A pure JavaScript reimplementation of git that works in both Node.js and browser environments (including WebWorkers and ServiceWorkers), with no native C++ dependencies. It reads and writes real '.git' directories, supports clone/fetch/push/commit/merge and more, and ships an 'isogit' CLI plus TypeScript type definitions.

## Use cases
- run git clone and push from browser JavaScript
- manipulate git repositories in Node.js without native git binary
- build a web app that commits files to GitHub client-side
- script git operations programmatically in JavaScript
- read git commit history and file status in a web IDE
- use git in environments where installing git is not possible

## When to choose
- you need git functionality in the browser or a JS runtime without native modules
- you want a programmatic git API in JavaScript with tree-shakeable functions
- you need interoperability with real git repositories on disk

## When to avoid
- you just need the standard git CLI on a desktop or server
- you need bleeding-edge git features or high performance on huge repositories
- you expect rapid feature development - the project is volunteer-maintained with limited coding capacity

## Facets
- artifact type: library
- maturity: maintenance
- function: version-control, http-client, cli, file-system
- domain: version-control, developer-tools, web-development
- platform: browser, cross-platform, cli, wasm
- tags: git, isomorphic, pure-javascript, no-native-modules, browser-git, pgp-signing, cors-proxy, command-line, nodejs, javascript
