This measures your connection to the siteIndex test server using three larger samples per direction. Results vary with Wi-Fi, browser limits, server distance, and network load.

How it works

siteIndex processes input directly in your browser whenever possible, which keeps the tool fast and keeps your data private.

For URL requests, the app validates the address and only allows public HTTP/HTTPS targets before running the check.

Common uses

• Debug a website or connection issue
• Validate data before sharing or publishing
• Prepare content or tokens for technical workflows

FAQ

• Is the data stored? No, browser-first tools do not store your content.
• What happens with URLs? They are validated before analysis.
• Can I use it on mobile? Yes, the interfaces are responsive and touch-friendly.
