How do Cloudflare Pages, GitHub Pages, and Vercel compare in terms of free tier limitations (bandwidth, build minutes, etc.)?

GitHub Pages offers unlimited bandwidth on the free tier, but build minutes are limited by your GitHub Actions usage. Cloudflare Pages provides a generous free tier with a substantial number of build minutes and bandwidth, but has limits on functions and worker invocations. Vercel's free tier is more restrictive in terms of build minutes and serverless function execution, but offers good performance and features for smaller projects.
