Understanding OpenStrand Architecture

January 7, 20258 min readBy Technical Team

OpenStrand is the connective tissue behind every Frame operating system. It is a distributed substrate that keeps data consistent, enforces security guarantees, and allows developers to extend the platform without reinventing the wheel.

Design Principles

We designed OpenStrand for a world where personal, home, and enterprise systems need to collaborate in real time while respecting privacy boundaries. Four principles guided the architecture:

  • Event First: Every interaction is an event that can be replayed, audited, and routed to the right subsystem.
  • Zero Trust: Security boundaries are explicit; components authenticate every message before acting.
  • Extensible by Default: Developers can attach new processors, adapters, or data sinks without forking core systems.
  • Deterministic State: Federated state machines ensure that replicas converge even when networks partition.

Event Bus

A high-throughput event bus coordinates messages between AgentOS, WorkOS, and external services. Subscribers can apply custom logic with latency budgets under 20ms.

Secure Envelope

Every payload is wrapped in an encrypted envelope with per-tenant signing keys. Policies can redact or transform messages at the edge.

State Mesh

CRDT-inspired synchronization keeps shared knowledge bases consistent while allowing each OS to cache and mutate local context safely.

Extensibility Hooks

Developers can register hooks to stream events into analytics pipelines, trigger automations, or integrate with existing infrastructure.

How Developers Extend OpenStrand

The OpenStrand SDK offers strongly typed bindings for TypeScript, Python, and Rust. You can publish custom services that listen for events, enrich them, and emit outcomes back into the mesh. Access control is handled by reusable policies so you can focus on business logic.

We’re already seeing partners build automation bridges, domain-specific knowledge bases, and even hardware integrations on top of OpenStrand. Whether you’re orchestrating a fleet of devices or embedding AI copilots in enterprise workflows, the substrate is ready for you.
