Apex & Custom Domains

A TanStack Start example of multi-tenant routing. You are on the apex domain (tracklet.dev). Each tenant below is reachable at its own subdomain — and optionally via a customer-owned custom domain — all served by this one app.

• A

  Acme Corp

  acme.tracklet.dev

  Custom domain: acme-widgets.com (try: curl -H 'Host: acme-widgets.com' http://tracklet.dev)

• G

  Globex

  globex.tracklet.dev
• I

  Initech

  initech.tracklet.dev

  Custom domain: initech.io (try: curl -H 'Host: initech.io' http://tracklet.dev)

Note: the tenant links above point at real subdomains, so the router renders them as full URLs via its output rewrite — view source to see.
