Auto-failover keeps apps running.

Model per app, with fallback.

Pick the best model for each app. Configure a fallback so an outage at one provider doesn't take your apps down.

Where your tools meet.

The apps worth building aren't dashboards. They pull data from across your stack, apply the logic your team actually uses, and trigger what happens next.
