mugit

A lightweight, self-hosted Git server that your cow will love.

See it in action!

Features

• Web interface — browse repositories, view commits, files, and diffs (no javascript required)
• Git Smart HTTP — clone over HTTPS (use SSH for pushing)
• Git over SSH — push and clone over SSH
• Mirroring — automatically mirror repositories (supports GitHub authentication)
• Private repositories — repos accessible only via SSH
• CLI — command-line for managing your repositories

Quick install & deploy

git clone https://git.olexsmir.xyz/mugit.git
cd mugit
go build

# or
go install github.com/olexsmir/mugit@latest

For nixos you can use our flake, see my config for reference.

Start the server:

# start server with default config lookup
mugit serve

# start with a custom config path
mugit -c /path/to/config.yaml serve

Configuration

mugit uses YAML for configuration. By default the server looks for a configuration file in this order (override with -c / --config):

1. ./config.yaml
2. /etc/mugit.yaml
3. /var/lib/mugit/config.yaml

Durations follow Go's duration syntax (examples: 1h, 30m, 5s). See: https://pkg.go.dev/time#ParseDuration

Minimal configuration example:

meta:
  host: git.olexsmir.xyz

repo:
  dir: /var/lib/mugit

Full example:

server:
  host: 0.0.0.0 # bind address (0.0.0.0 = all interfaces)
  port: 5555    # HTTP port (defaults to 8080 when omitted)

meta:
  title: "My Git Server"    # site title shown on index page
  description: "A place for my projects"
  host: git.example.com     # used for clone URLs and go-import meta tag

repo:
  dir: /var/lib/mugit   # directory with repositories
  # Default README filenames (applied when omitted):
  readmes:
    - README.md
    - readme.md
    - README.html
    - readme.html
    - README.txt
    - readme.txt
    - readme
  # Default branch names considered the repository 'master' (applied when omitted):
  masters:
    - master
    - main

# ssh: push/clone over SSH
ssh:
  enable: true
  port: 2222  # SSH port (default 2222)
  user: "git" # user as which the app operates (default "git")
  host_key: /var/lib/mugit/host   # path to SSH host key (generate with ssh-keygen)
  # Only these public keys can access private repos and push to others.
  keys:
    - ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAA......
    - ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAA......

# mirror: automatic mirrors of external repositories
mirror:
  enable: true
  interval: 1h  # sync frequency
  # Tokens can be provided directly, or read from environment/file:
  # - literal: "ghp_xxxxxxxxxxxx"
  # - from env: "$env:GITHUB_TOKEN" (will read $GITHUB_TOKEN)
  # - from file: "$file:/abs/path/to/token.txt"
  github_token: "${env:GITHUB_TOKEN}"

cache:
  home_page: 5m   # cache index/home page
  readme: 1m      # cache rendered README per repo
  diff: 15m       # cache computed diffs

CLI

# start server
mugit serve

# create new public repository
mugit repo new myproject

# create new private repository
mugit repo new --private myproject

# create a mirror of an external repository
mugit repo new myproject --mirror https://codeberg.org/user/repo
mugit repo new myproject --private --mirror https://github.com/user/repo

# toggle repository visibility
