# CDN Tools and Calculators

This section collects practical tools for people who plan, run and pay for content delivery. It is for DevOps and SRE teams, video engineers, performance specialists and FinOps leads who want quick answers: how much bandwidth a stream needs, how fast a CDN really is from different regions, which CDN a website uses, or what a month of traffic will cost.

You will find bitrate and bandwidth calculators, storage and pricing calculators, latency testing methods, CDN analytics and monitoring tools, cache header debugging with curl, and curated tool lists for DevOps and security teams. Most tools come with a short guide on reading the results. For cost questions, pair them with the [cost optimization](https://blog.blazingcdn.com/cost-optimization?hsLang=en) guides.
