Check Repo Sizes in an Organization

1. Create a GitHub Personal Access Token (PAT):

• Go to GitHub → Settings → Developer settings → Personal access tokens.

• Create a Fine‑grained token with at least read‑only repo scope.

• If your org enforces SSO, click Authorize for your org after creating the token.

• Copy the token (it looks like ghp_xxxxx...).

  

2. Store the Token in PowerShell:

   $env:GITHUB_TOKEN="ghp_yourtokenhere"

3. Call the GitHub API: Run PowerShell script that lists all repos in your org with their sizes. Please change {YOUR-ORG-NAME}

   In GB

   $headers = @{ Authorization = "token $env:GITHUB_TOKEN" }
   $response = Invoke-WebRequest -Uri "https://api.github.com/orgs/{YOUR-ORG-NAME}/repos?per_page=100" -Headers $headers
   $repos = $response.Content | ConvertFrom-Json
   
   # Show name and size in GB
   $repos | Select-Object name, @{Name="SizeGB";Expression={[math]::Round($_.size/(1024*1024),2)}} | Sort-Object SizeGB -Descending

   E.g in GB:

   

   In KB:

   $headers = @{ Authorization = "token $env:GITHUB_TOKEN" }
   $response = Invoke-WebRequest -Uri "https://api.github.com/orgs/{YOUR-ORG-NAME}/repos?per_page=100" -Headers $headers
   $repos = $response.Content | ConvertFrom-Json
   
   # Show name and size in MB
   $repos | Select-Object name, @{Name="SizeMB";Expression={[math]::Round($_.size/1024,2)}} | Sort-Object SizeMB -Descending

   E.g in KB:
