# Editions & Architecture

Sitecopilot is available in two editions:

* **Sitecopilot Pro (Cloud)**: hosted by Sitecopilot or partners. Turn‑key, managed updates, and integrated **Cloud Agent** for AI-assisted editing.
* **Sitecopilot CE (Community Edition, Open Source)**: self-hosted core CMS. You can run sites fully manually without AI. To enable AI-assisted editing, CE connects to **Sitecopilot Cloud** (the managed AI agent & endpoints).

## Architecture (high level)

* **Core CMS (tenant)**: pages, content, assets, settings, notifications.
* **Central domain**: tenant lifecycle, tenant API tokens.
* **Sitecopilot Cloud Agent**: AI orchestration (RAG, proposals, editor messaging). Both Pro and CE use this for generative features.

> Data sovereignty: host the CMS where you want; AI calls go to Sitecopilot Cloud. You control when/what is sent (opt‑in per feature), and you can operate fully manual if needed.
