About HostedSiteDemo

HostedSiteDemo is a free set of calculators and generators for people who build, launch and look after websites: freelancers, small agencies, developers and business owners doing it themselves. The calculators help you choose and budget for hosting; the generators produce the meta tags, robots.txt, redirect rules and sitemaps that every site needs.

Estimates such as load times and bandwidth are based on stated formulas and typical figures. Real-world results depend on your host, caching, CDN and visitors, so treat them as a planning guide.

Who builds it

HostedSiteDemo is built by Sumair Roudani, founder and CEO of the software company Avancera Solution and a PMP-certified project manager who has planned, built and launched client websites and web apps for more than 13 years. .

How we build and check the tools

  • Every tool runs entirely in your browser: fast, free and private.
  • Each page shows the formula it uses, so you can check the maths yourself.
  • We test results against worked examples and published references before a tool goes live, and review pages regularly.
