Tracenow installs a managed Worker on your Cloudflare zone. It scores and enforces on every signup, login, and OTP. Zero changes to your app.

  1. 1

    Connect Cloudflare

    Paste a scoped API token (Workers: Edit, Zone DNS: Read). We verify it and list your zones.

    Map your routes

    Tell us which paths are signup, login, or OTP, e.g. POST /login becomes a login event.

  3. 3

    Deploy

    One click. We upload the Worker to your zone. Traffic is scored and enforced at the edge from that moment.
