Custom domains & TLS - included with every app →

Bring your own domain. We do the rest.

Point your domain at Sarpius. We verify DNS, issue TLS, and route traffic to the right app.

A custom domain shouldn't be a project.

One field. DNS, TLS and routing handled. Cert provisioning takes ~2 seconds the first time you add a domain - every request after that is milliseconds.

the edge surface

Every domain gets a managed certificate.

Sarpius Router verifies your DNS, issues a Let's Encrypt certificate, and renews it 30 days before expiry. You ship your app - we keep the lock closed.

Built for the domains
your customers actually type.

From a single brand domain to thousands of customer-supplied hostnames - Sarpius Router scales without you touching nginx.

bring your own domain

Plug your domain into any app.

Add a CNAME at your registrar, paste the domain into Sarpius Router, and we wire it up. Apex domains supported via ALIAS / ANAME.

CNAME ALIAS apex
multi-tenant

Customer-supplied hostnames at scale.

White-label one app behind thousands of domains. Every tenant gets their own cert, auto-issued and auto-renewed.

staging & previews

Same app, different hostnames.

Route staging.example.com to a preview branch, www.example.com to production - without juggling DNS zones.

TLS, hands-off

Let's Encrypt without the cron job.

ALPN-01 challenges happen at the edge. Renewals trigger 30 days before expiry. Failures page us - not you.

what's new

Traffic routing that scales with your app.

Sarpius Router gained autoscaling-aware routing, bandwidth metering, and real-time pool health visibility.

Multi-replica round-robin

Requests spread across every healthy replica. Failed upstreams are pulled from rotation automatically - no manual config.

Bandwidth metering with warnings

Per-app bandwidth tracked at the edge. Email warnings fire at 80% and 100% of your included bundle before you overspend.

User-configurable hard cap

Set a traffic cap per app. Once reached, Sarpius Router stops forwarding requests - no surprise bandwidth bills.

Request-rate metering

Per-app RPS measured at the proxy, sent to the autoscaler. Scale-up and scale-down decisions use real edge traffic data.

Pool health visibility

Each router instance publishes replica counts and healthy counts in its heartbeat, giving ops a live view of every app pool.

Sub-second pool reload

When an app scales up or down, the routing pool refreshes in under a second via APP_REPLICA_CHANGED events - zero manual restarts.
