Concepts, interactive tools, and the projected SDK/API experience

The Playground is live today. Published npm/PyPI packages and the hosted API are still in progress — examples below are marked as projected.

Quickstart: Build Your First Organism

Projected CLI & SDK flow

Not published yet

Prefer something that works now? Open the Cytos Playground to create organisms, compose tissues, and run simulations in your browser.

Step 1: Install the Cytos CLI

Projected @cytos/cli is not on npm yet. This shows the planned install command. 
npm install -g @cytos/cli

Step 2: Explore locally in the Playground

Hosted API keys are not issued yet. Use the Playground for local organism state while the platform API ships.

Step 3: Initialize your first organism

Projected CLI commands below will apply once @cytos/cli is published. 
cytos init my-organism
cd my-organism

Step 4: Create your first cell

Projected Python package cytos-sdk is not on PyPI yet — example of the planned SDK surface. 
# Using Python SDK (projected)
from cytos import CellEngine

engine = CellEngine(api_key="your-api-key")
cell = engine.create_cell(
    name="hello_cell",
    capabilities=["process", "respond"]
)
cell.start()

Step 5: Deploy to Cytos Cloud (optional)

Projected Cloud deploy is not live. Use Playground export/simulation until managed runtime launches. 
cytos deploy

Concepts: Cells, Tissues, Organisms, Ecosystems

Cells

Individual agents that operate autonomously. The building blocks of digital organisms.

Tissues

Groups of cells working together to perform specific functions.

Organisms

Complete systems composed of multiple tissues and organs.

Ecosystems

Networks of organisms interacting in shared environments.

Agent Communication Graph

Live browser simulation of agent-cell messaging. Watch packets route across tissues while load, health, and queues update in real time.

This is a client-side communication engine — not the hosted API. Hover nodes to inspect state, inject message types, and switch organism presets. The same engine powers the Playground Simulate tab.

SDKs & API Reference

Planned language SDKs and REST surface for Cell Engine, OrganismOS, and Cytos Cloud. Packages and the public API endpoint are not published yet.

Python SDK

Official Python SDK with full type hints and async support.

Projected Not on PyPI yet. 
pip install cytos-sdk
View Python Docs →

JavaScript/TypeScript SDK

Node.js and browser support with full TypeScript types.

Projected Not on npm yet. 
npm install @cytos/sdk
View JS Docs →

REST API

Complete REST API with GraphQL support and OpenAPI spec.

Projected Hosted endpoint not live yet.

Also planned: Go SDK • CLI tools • Webhooks • WebSocket API — join the community for release updates.

Security & Sandboxing

Security is designed into every layer of Cytos. Cells are intended to run in isolated sandboxes with resource limits. Access controls, encryption, and audit logging are part of the platform roadmap. Learn about the planned sandboxing model and best practices for building secure digital organisms.
