[git] How can I see the size of a GitHub repository before cloning it?

Is there a way to see how big a Git repository is on GitHub before you decide to clone it?

This seems like a really obvious/basic statistic, but I can't find how to see it on GitHub at all.

@larowlan great sample code. With the new GitHub API V3, the curl statement needs to be updated. Also, the login is no longer required:

curl https://api.github.com/repos/$2/$3 2> /dev/null | grep size | tr -dc '[:digit:]'

For example:

curl https://api.github.com/repos/dotnet/roslyn 2> /dev/null | grep size | tr -dc '[:digit:]'

returns 931668 (in KB), which is almost a GB.

To summarize @larowlan, @VMTrooper, and @vahid chakoshy solutions:

#!/usr/bin/env bash


if [ "$#" -eq 2 ]; then
    echo "$(echo "scale=2; $(curl https://api.github.com/repos/$1/$2 2>/dev/null \
    | grep size | head -1 | tr -dc '[:digit:]') / 1024" | bc)MB"
elif [ "$#" -eq 3 ] && [ "$1" == "-z" ]; then
    # For some reason Content-Length header is returned only on second try
    curl -I https://codeload.github.com/$2/$3/zip/master &>/dev/null  
    echo "$(echo "scale=2; $(curl -I https://codeload.github.com/$2/$3/zip/master \
    2>/dev/null | grep Content-Length | cut -d' ' -f2 | tr -d '\r') / 1024 / 1024" \
    | bc)MB"
else
    printf "Usage: $(basename $0) [-z] OWNER REPO\n\n"
    printf "Get github repository size or, optionally [-z], the size of the zipped\n"
    printf "master branch (`Download ZIP` link on repo page).\n"
    exit 1
fi

If you own the repository, you can find the exact size by opening your Account Settings ? Repositories (https://github.com/settings/repositories), and the repository size is displayed next to its designation.

If you do not own the repository, you can fork it and then check the in the same place.

Note: You might be the owner of the organization that hosts multiple repositories and yet not have a role in a specific repository inside the organization. By default, even if you create a repository in the organization you own, you are not added to the repo and hence not see that repo in settings/repositories. So add yourself in the repository Setting(https://github.com/org-name/repo-name/settings) to see it in https://github.com/settings/repositories

Somewhat hacky: use the download as a zip file option, read the file size indicated and then cancel it.

I do not remember if downloading as a zip ever worked, but in any case, doing so now only downloads the currently selected branch with no history.

You need to follow the GitHub API. See the documentation here for all the details regarding your repository. It requires you to make a GET request as:

GET /repos/:owner/:repository

You need to replace two things:

1. :owner - the username of the person who owns the repository
2. :repository - The name of the repository

E.g., my username maheshmnj, and I own a repository, flutter-ui-nice, so my GET URL will be:

https://api.github.com/repos/maheshmnj/flutter-ui-nice

On making a GET request, you will be flooded with some JSON data and probably on line number 78 you should see a key named size that will return the size of the repository.

Tip: When working with JSON I suggest you to add a plugin that formats the JSON data to make reading JSON easy. Install the plugin.

For a private repository, you will need to obtain a Personal Access Token from https://github.com/settings/tokens.

Then use the following curl command to get the details (substituting in values for [token], [owner] and [name]):

curl -u git:[token] https://api.github.com/repos/[owner]/[name] 2> /dev/null | grep size

As mentioned earlier, size may be in MB or KB.

To do this with curl (sudo apt-get curl) and json pretty (sudo gem install jsonpretty json):

curl -u "YOURGITHUBUSERNAME" http://github.com/api/v2/json/repos/show/OWNER/REPOSITORY |
  jsonpretty

Replace YOURGITHUBUSERNAME with your GitHub username (go figure).

Replace OWNER with the repository owner's Git username. Replace REPOSITORY with the repository name.

Or as a nice Bash script (paste this in a file named gitrepo-info):

#!/bin/bash
if [ $# -ne 3 ]
then
  echo "Usage: gitrepo-info <username> <owner> <repo>"
  exit 65
fi
curl -u "$1" http://github.com/api/v2/json/repos/show/$2/$3|jsonpretty

Use it like so:

gitrepo-info larowlan pisi reel

This will give me information on the pisi/reel repository on GitHub.

You can do it using the Github API

This is the Python example:

import requests


if __name__ == '__main__':
    base_api_url = 'https://api.github.com/repos'
    git_repository_url = 'https://github.com/garysieling/wikipedia-categorization.git'

    github_username, repository_name = git_repository_url[:-4].split('/')[-2:]  # garysieling and wikipedia-categorization
    res = requests.get(f'{base_api_url}/{github_username}/{repository_name}')
    repository_size = res.json().get('size')
    print(repository_size)

If you use Google Chrome browser you can install the GitHub Repository Size extension.

Repo here: https://github.com/harshjv/github-repo-size

If you're trying to find out the size of your own repositories.

All you have to do is go to GitHub settings repositories and you see all the sizes right there in the browser no extra work needed.

https://github.com/settings/repositories

One can achieve this using one's browser console and running

fetch('https://api.github.com/repos/[USERNAME]/[REPO]')
  .then(v => v.json()).then((function(v){
   console.log(v['size'] + "KB")
  })
)

Let's consider a practical example.

Assuming one wants to find the size of this repo using Firefox.

Open the console with Ctrl+Shift+K.

Then paste the following code

fetch('https://api.github.com/repos/goncaloperes/TimeSeries')
  .then(v => v.json()).then((function(v){
   console.log(v['size'] + "KB")
  })
)

Press enter and one will receive the size of the repo as one can see in the image bellow.

From JavaScript, since the Github API is CORS enabled:

fetch('https://api.github.com/repos/webdev23/source_control_sentry')
  .then(v => v.json()).then((function(v){
   console.log(v['size'] + "KB")
  })
)
