Is it possible to remote count object and size of git repository?

Assume that somewhere in the web exists public git repository. I want to clone it but firstly i need to be sure what is size of it (how much objects & kbytes like in git count-objects)

Is there a way to do it?

Solution 1:

One little kludge you could use would be the following:

mkdir repo-name
cd repo-name
git init
git remote add origin <URL of remote>
git fetch origin

git fetch displays feedback along these lines:

remote: Counting objects: 95815, done.
remote: Compressing objects: 100% (25006/25006), done.
remote: Total 95815 (delta 69568), reused 95445 (delta 69317)
Receiving objects: 100% (95815/95815), 18.48 MiB | 16.84 MiB/s, done.
...

The steps on the remote end generally happen pretty fast; it's the receiving step that can be time-consuming. It doesn't actually show the total size, but you can certainly watch it for a second, and if you see "1% ... 23.75 GiB" you know you're in trouble, and you can cancel it.

It seems that the link will now be redirected to another URL, so we need to add -L to curl to follow the redirection.

curl -sL https://api.github.com/repos/Marijnh/CodeMirror | grep size

For github repository, it now offer API to check file size. It works!

This link: see-the-size-of-a-github-repo-before-cloning-it gave the answer

Command: (answer from @VMTrooper)

curl https://api.github.com/repos/$2/$3 | grep size

Example:

curl https://api.github.com/repos/Marijnh/CodeMirror | grep size
 % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                Dload  Upload   Total   Spent    Left  Speed
100  5005  100  5005    0     0   2656      0  0:00:01  0:00:01 --:--:--  2779
"size": 28589,

Solution 3:

Doesn't give the object count, but if you use Google Chrome browser and install this extension

It adds the repo size to the home page:
