There is a lengthy topic Add automated kill switch or rate limiting to prevent excess billing from DDOS attacks about the 100k bill and ways to mitigate this.
Keep in mind Netlify don’t have a “Free” plan they have a “Starter” plan that starts at $0/month. Cloudflare does have a “Free” plan, it doesn’t include all services/functionality so isn’t necessarily free.
