# RealizeOS

> RealizeOS is a self-hosted AI operations system: coordinated agents that share one knowledge base about the business, remember past work and act only within approval gates. Realization built it to run its own operations and publishes the core under a source-available licence.

- Category: Systems (ai operating system · open core)
- Status: Live
- Location: Self-hosted · runs anywhere
- Realization's role: Designed and built by Realization; runs our own operations
- Stack: Python 3.11, FastAPI, SQLite FTS5, React 19, Anthropic Claude, Google Gemini, OpenAI via LiteLLM, Ollama (local), MCP server

## Key facts

- **54.5k** — lines of Python, plus 11.5k of TSX
- **2,032** — automated tests across 99 files
- **24** — MCP tools exposed to other agents
- **4** — LLM providers, routed by task and cost

## Problem

Most teams adopted chatbots, not an AI operation. Every chat starts from zero, work isn’t followed through, and the knowledge lives with the model vendor.

## Approach

Keep the durable asset — knowledge, history and identity — in files the business owns. Everything else is a swappable adapter: models, agent runtimes, channels and interfaces.

## Outcome

Version 5.6 runs Realization’s research, documentation and coordination daily. The core is free to self-host; setup and adaptation are available through Advisory.

## Context → coordinated action.

Six hard problems, solved as one stack.

1. **Knowledge** — FABRIC: plain markdown the team can edit, round-tripped into typed entities.
2. **Memory** — Synapse: a four-tier index that recalls the cheapest context first.
3. **Missions** — An eight-state engine that plans, routes and tracks the cost of every step.
4. **Governance** — Six roles, injection guards, audit logs and human approval on consequential actions.

Note: Source-available under BSL 1.1. Counts are measured from the repository.
