Overview

The Allternit platform follows a unique architectural pattern that separates the core intelligence (Brain) from the user interfaces (Faces) while maintaining a unified communication layer (Nervous System).

The Brain (Gizzi)

Gizzi is the central orchestration engine responsible for:
  • Agent lifecycle management - Creating, running, and terminating agents
  • Code execution and sandboxing - Secure environment for agent code
  • Model interaction - Prompt engineering and LLM communication
  • State management - Persistence and memory for agents
  • Event coordination - Message routing between agents

The Faces (Surfaces)

Surfaces are the user-facing interfaces that interact with the Brain:

Desktop App

Packaged Electron app — loads the platform, manages local VMs, global hotkeys

Platform

Next.js 15 web shell — chat, code, workspace, design, and Agent Hub

Extensions

Chrome extension for browser automation + Office add-ins for Excel/Word/PowerPoint

The Nervous System (SDK)

The SDK provides a unified interface for all surfaces to communicate with the Brain:

Communication Layer

The ac (Agent Communication) protocol is Allternit’s inter-agent messaging layer. It provides:
  • Message Board - Persistent, ordered message log per channel
  • Git DAG - Cryptographically auditable lineage for every message
  • API Keys - Per-agent scoped keys with rate limiting

Deployment Models

Fully managed deployment on Allternit’s infrastructure. Best for:
  • Quick prototyping
  • Teams without DevOps resources
  • Automatic scaling
Deploy the runtime agent to your own infrastructure:
Best for:
  • Data privacy requirements
  • Compliance (SOC2, HIPAA)
  • Existing infrastructure
Control plane on Allternit Cloud, data plane on your infrastructure. Best for:
  • Sensitive data processing
  • Cost optimization
  • Gradual migration
