Test a relay site with your own key

Enter a relay site and your key for it. Your browser sends 8 fixed probe requests straight to that site (4 output tokens each; a full test usually costs well under a cent) and compares the returned token counts, echoed model name and time-to-first-byte against reference counts we derived from multiple channels.The key stays in your browser only: never uploaded, never stored, never routed through our servers.
