Why Areca CMS

Most headless CMSs are built for one company with one website. Agencies have the opposite problem: dozens of clients, each with a site or two, each with people who should only see their own content.

Areca CMS is built around that. One installation holds all your clients. Each client gets its own sites, owners and editors, and your agency admins see everything. Editors write drafts, owners mark them ready, and Go live freezes the approved content into a snapshot and deploys the site. The website pulls that snapshot while it builds, so visitors get static pages and never touch the CMS.

• Built for agencies. Clients, sites and roles per client (owner, editor), an agency dashboard across all of them, and your own branding on the CMS.
• Visual editor. Edit next to a live preview of the real site, and click any part of the page to jump to its field.
• A safe publishing flow. Draft → ready → live, with scheduling, release history, rollback and health checks. A failed deploy never replaces the live site.
• Made for AI. Every site has an MCP server, so Claude, ChatGPT, Cursor and other AI apps can write drafts with the same permissions as the person who connected them. Agent skills teach coding agents to wire up a new site.
• SEO and AI answers. Search, social and structured-data fields on every entry, with optional AI suggestions through OpenRouter.
• Multilingual content, rich text with code blocks, a media library, and site-wide content such as company info.
• Deploys where you do. Built-in adapters for Dokploy and Cloudflare (Pages and Workers), and a throwaway development environment per site.
• Typed from schema to page. Define content in areca.config.ts, and @areca-cms/site-sdk generates types for every collection.
• Secure by default. Two-factor authentication, Google and Microsoft sign-in, step-up checks for sensitive actions, and a tested permissions matrix.

Visual editor: click the page to edit it.	Go live: see exactly what changes before it ships.
SEO built in: search, social and AI-answer fields.	Connect AI: one URL for Claude, ChatGPT or Cursor.

Quick start

1. Run the CMS

You need Docker with Compose v2. This starts the CMS with PostgreSQL, Redis, S3-compatible storage and a test inbox:

git clone https://github.com/seirai-dev/areca-cms.git
cd areca-cms/docker
cp .env.example .env    # then set the secrets, see the comments in the file
docker compose up -d --wait

Open http://localhost:3000/setup and create the first admin. The setup token is printed in docker compose logs cms. The Docker quick start explains each setting, and Production covers a public install.

2. Connect a website

Create a client and a site in the CMS and copy the site token. Then, in your website project:

pnpm add @areca-cms/site-sdk
pnpm exec areca init

Describe your content in areca.config.ts, push it with areca manifest push, and pull the content during your build with areca pull. The guide walks through a full site, from the first collection to the first release.

Using an AI coding agent? Run npx @areca-cms/skills, then ask it to /areca-quickstart.

How publishing works

Draft ─► Mark as ready ─► Go live ─► Content snapshot ─► Website build pulls it ─► Deploy ─► Health check ─► Live

Editing a draft never changes the live site. Only approved versions go into a release, and a release only counts as live after the health check confirms the website serves it. If a deploy fails, the previous version stays live, and any earlier release can be rolled back. Previews of drafts are fetched from the CMS on demand. Concepts explains the model in more detail.

What's in this repository

The CMS is a TanStack Start app on PostgreSQL with Drizzle, Redis and S3-compatible storage. The interface is available in English, Dutch and Turkish.
