Domain & Multi-Tenant Hosting

Tenant resolution is host-based. Streamly reads the normalized Host header (works behind any proxy that preserves it).

Customer-owned custom domains are not supported. There is no Cloudflare for SaaS / /api/v1/domains provisioning in the current product. Tenants use the platform host or {slug}.streamly.watch.

Host patterns

Host	Tenant
`NEXT_PUBLIC_PLATFORM_HOST` (e.g. `streamly.watch`)	Default / brand tenant
`localhost` / `*.workers.dev`	Dev / preview default tenant
`{slug}.streamly.watch`	Tenant matched by slug

API clients may also pass an explicit x-streamly-tenant-id header.

Reserved platform hosts & slugs

Reserved hostnames include streamly.watch, www, admin, app, api. Reserved subdomain slugs (cannot be used as tenant slugs): www, api, admin, app, customers.

Environment

Variable	Purpose
`NEXT_PUBLIC_APP_URL`	Canonical public URL
`NEXT_PUBLIC_PLATFORM_HOST`	Platform host (no scheme)
`NEXT_PUBLIC_STREAMLY_API_BASE`	Usually `https://host/api/v1`
`PUBLIC_CATALOG_TENANT_SLUG` / `DEV_TENANT_SLUG`	Optional pin for default tenant

DNS and TLS for your platform host are managed by your hoster or Cloudflare Workers routes — not an in-app custom-hostname API.

Admin / dashboard hosting

/admin and /dashboard are served on the platform host. Visiting them on a tenant host redirects to NEXT_PUBLIC_PLATFORM_HOST.
