GitHub Repo Size
— Check the size of any GitHub repository by entering the owner and repository name or pasting a GitHub URL. The tool fetches repository data from the GitHub API and displays the total size in kilobytes, megabytes, or gigabytes depending on the repository's scale. Results are automatically saved to the browser URL, allowing you to share or revisit repository size checks.
GitHub doesn't tell you the repo size in the UI, but it's available in the CORS-friendly API. Paste a repo into this tool to see the size, for example for simonw/datasette (8.1MB).
