The autonomic fabric.
Discovery, mTLS, and routing across every autonomous actor and every resource an actor reaches — rooted in Sigil identities, not hardcoded URLs.
What it is
A plexus is the network of nerves and vessels in a living body that carries signals among autonomic systems. Plexus does the same for autonomous-system fabric. Every connection is rooted in Sigil identities. Every message is authenticated, encrypted, and routed with awareness of actor semantics. Agents find other agents, MCP servers, tools, and robotic actuators by capability descriptor — not by URL. The brittle web of point-to-point coupling that defines autonomous-system estates today gives way to capability-based discovery rooted in identity.
The problem
Autonomous systems today find their dependencies by hardcoded URL. A bash variable points the agent at an MCP server. A configuration file points the robot at a planner. Mutual authentication is haphazard. The estate becomes a brittle web of point-to-point coupling with no consistent answer to who is reachable, who is calling whom, and whether every connection is authenticated.
Capabilities
Open and commercial
Plexus is delivered through two surfaces: an open-source reference in Lattice Runtime (MPL 2.0), and a managed, enterprise-grade delivery in Visca Cloud. Features in the open never move behind the paywall.

Cryptographic identity for autonomous actors.
Issues, verifies, and revokes the cryptographic identity every autonomous actor holds — bound to principal, runtime, and lineage from the moment of instantiation.
Zero-trust access for autonomous actors.
Brokers every access from an autonomous actor to a consequential resource — identity-bound, scoped, time-limited, audited. Long-lived credentials disappear.
Across the platform
The system of record.
A queryable knowledge graph of every autonomous actor in the estate — and the append-only, cryptographically chained audit of every action taken.
Data model as code.
The declarative primitive for your data model. Agents write it as source; humans edit it as a spreadsheet. Plan, apply, drift-detect.
Reproducible bundles for autonomous actors.
Immutable, content-addressed, Sigil-signed bundles. Everything an autonomous actor needs to execute, packaged as a single attestable artifact.
Autonomy-aware runtime.
Runs autonomous workloads across cloud, edge, on-device, and on-robot — with first-class awareness of tokens, models, memory, and embodiment.
The autonomy economy is shipping
Build, run, and trust autonomous systems on an integrated platform — software, embodied, and hybrid. Open foundation. Enterprise cloud. No license rug-pulls, ever.
