modular system controller

Operate fleets with
surgical precision.

A modular system controller built on a simple contract: a small agent on every device, mutual TLS in between, and a single control plane that sees it all.

01 · agent runtime

Runs on every
managed device.

The agent is a single Go binary that boots on each host you manage. It exposes a small mTLS-protected API and loads modules at build time — only the capabilities you ship are present.

Modules report live state, accept configuration, handle RPCs, stream over WebSockets, and push notifications.

02 · mTLS connection

Every byte is
authenticated.

Agent and platform exchange X.509 certificates and verify each other before a single byte flows. Neither side trusts the other on hostname alone.

No shared secrets, no API keys in transit. Cert rotation is a deploy, not an outage.

03 · platform

One control plane.
Everything visible.

The platform is the operator's cockpit. Live state from every agent, an AI assistant that knows your fleet, notifications routed by severity, and integrations with the systems you already run.

AI assistant

Ask questions in natural language. The assistant reads live module state across the fleet.

Device state

Real-time dashboards rendered straight from the agent. Five-second polling, no caches.

Notifications

Severity-routed events from every module. Mark, mute, escalate.

Integrations

Webhooks, MCP, and a clean REST API. Plug into the rest of your stack.
