GitHub doesn't tell you the repo size in the UI, but it's available in the CORS-friendly API (https://api.github.com/repos/simonw/datasette). Paste a repo into this tool to see the size, for example for simonw/datasette (https://tools.simonwillison.net/github-repo-size?repo=simonw%2Fdatasette) (8.1MB).
