Linkup

Required Cloudflare Resources

Account-scoped:

  • A Cloudflare Worker script running the Linkup worker
  • Two Cloudflare KV namespaces: LINKUP_SESSIONS (session state) and LINKUP_TUNNELS (provisioned tunnel records)
  • An account-level API token used by the worker to provision tunnels

Per zone you deploy to:

  • DNS records (* and @) pointing the zone at the worker
  • Worker routes *.mydomain.com/* and mydomain.com/* binding the zone’s traffic to the worker

On the tunnel zone (the first zone passed to --zone-ids) only:

  • DNS records for linkup-tunnel-* hostnames, created at runtime as sessions start
  • A cache rule that excludes those tunnel hostnames from Cloudflare’s cache
