Mantle

The shared platform layer — the upstream you build a fleet against. Mantle is the server-side of the platform. Run it once for your whole fleet: an air-gap-friendly git remote, a hardened MQTT broker, the primary Sparkplug host, and Fleet — the control plane that drives rollouts, secrets, and remote ops across every edge node. Pilot rate available while experimental. What you get: • Git Server — air-gap-friendly remote for the GitOps repo • MQTT Broker — production-grade, TLS + ACLs, Sparkplug-aware • Sparkplug Host — primary host application for the namespace • Fleet — fleet-wide visibility, rollout control, and remote ops • HMI — operator interface bound directly to platform tags • History — time-series historian with rollups, retention, and store-and-forward Includes a Tentacle license — every protocol driver and platform service in Tentacle, at no extra cost. Buy once for a perpetual, version-locked license. Add the annual support and upgrade subscription for new features, security patches, and direct help when you need it.
