FIG 1.0 — DEVELOPER SURFACE

Real tool. Decide in ten seconds.

Fetch typed content and render blocks you own. Same content over the SDK, GraphQL, or the MCP server.

// app/[[...path]]/page.tsx — you own this file
import { createCmssyPage } from "@cmssy/next/server";
import { blocks } from "@/cmssy/blocks";
import { cmssy } from "@/cmssy.config";

export default createCmssyPage(cmssy, blocks);

FIG 2.0 — THE DIFFERENTIATOR

AI that edits your content. Never code you paste.

Connect Claude through cmssy's MCP server and it works inside your workspace — creating pages, writing copy, and translating. It edits structured content directly, so nothing lands in your repo unreviewed.

  • 70+ MCP tools — pages, blocks, media, forms, commerce, publishing.
  • Content-only writes — the AI never touches your frontend code.
  • Versioned & reversible — every publish has version history and rollback.

FIG 3.0 — ONE PLATFORM, TWO AUDIENCES

Business teams manage content. Developers own the frontend.

Nobody steps on anybody. One content model, two ways to work.

FOR CONTENT TEAMS

Visual editor, live preview

Marketers and editors change content and see exactly what ships. No tickets, no redeploys, no touching code.

FIG 3.1
FOR DEVELOPERS

You own the frontend

cmssy never hosts your site. Render published content in your own Next.js app with the SDK and deploy it anywhere.

import { CmssyPage } from "@cmssy/next";

const page = await cmssy.pages.get({ slug });
return <CmssyPage page={page} />;

FIG 4.0 — BUILT IN, NOT BOLTED ON

Everything a CMS should do — and things most don’t

Revisions, commerce, permissions, webhooks. Each with a real number, not a promise.

Version history

Every publish is versioned. Roll back any page to a previous state.

Version history & rollback

Native commerce

Products, carts, orders, discounts, order pipelines and inventory.

Real commerce, not a plugin

Forms & submissions

Build forms and manage submissions right in your workspace.

15 field types

Webhooks & typed API

React to content changes and query everything over GraphQL.

Typed public API

Roles & permissions

Custom roles so the right people touch the right content.

50+ granular permissions

Multilingual by default

Every field is per-language out of the box, delivered automatically.

Every field localized
