Yes — many developers on the board do. ccusage reads local logs from every supported agent, and a single npx viberank-cli submission records your usage per tool, so your profile shows exactly how your spend splits between them.
Numbers come from developers who submit their ccusage data to Viberank — real token counts and API-equivalent costs computed from local session logs, validated server-side. It measures actual usage, not marketing claims.
