Simon Willison Ships GitHub Repo Size Tool — CORS-Friendly API, Paste-and-Check
Simon Willison published a lightweight browser tool on April 9 that shows GitHub repository sizes using GitHub's CORS-friendly API. GitHub doesn't expose repo size in the UI, but the API returns it. Paste a repo URL and get the size instantly — useful for evaluating whether to clone large repos or understanding project scale before contributing. Part of Willison's growing tools.simonwillison.net collection of LLM-generated HTML/JS utilities.
