A little about how the tools keep your data private and work for free.
Yes. Each tool needs no account and has no usage limits. The only network requests are to public proxy services used to fetch a scanned website for the SEO and speed checkers — and never to upload your own data.
No. The file is read directly in your browser and parsed locally. "Your app file never leaves this tab" — none of its bytes are transmitted.
Browsers block cross-origin requests, so the SEO and speed tools call a public proxy to fetch remote pages. If a site blocks the proxy, you may see a partial result — the tools fall back across multiple proxies automatically.
Mostly yes. The sitemap tool exports sitemap.xml; the app auditor exports JSON, CSV and SARIF; the SEO and speed tools offer copy-and-download of their reports.
Start with whichever fits your next task — each is a single click away.
