Common questions

Is NextBlock CMS safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: Authorization

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed yesterday, and the latest version (1.0.0) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT on the web (full MCP on Business and above; Pro read-only).

What can I use instead?

NextBlock™ CMS

The open-source, full-stack AI-native CMS for Next.js 16, Supabase, and Tailwind CSS.

Deploy a production Next.js 16 + Supabase website and CMS in one click.

Vercel provisions the database and injects its keys before the first build, NextBlock applies its own

schema during that build, and the in-app wizard asks only for your admin account.

No environment variables to fill in.

🚀 Why NextBlock™?

Tired of slow WordPress sites? Finding headless CMSs too complex? NextBlock™ is the sweet spot.

We combined the flexibility of a Block Editor with the raw power of Next.js 16 Server Components. The result is a CMS that feels like a static site but manages like a dynamic platform.

✨ Key Features

▲ Next.js 16 App Router + React 19 Server Components: the public site renders on the server — page, article and product routes are all Server Components — with client components reserved for cart, checkout, forms and the CMS dashboard.
🗄️ Supabase PostgreSQL with JSONB block storage: every content block is a row in public.blocks with a jsonb content column. User-defined block types live in custom_block_definitions (fields / layout_schema as jsonb, guarded by Postgres CHECK constraints) and render without a rebuild.
🚀 Zero-config 1-click migrations: the Vercel Supabase integration provisions the database and injects its keys before the first build; NextBlock then applies its own forward-only migrations *during that build* (tools/build-migrate.mjs), with a runtime fallback in the /setup wizard. Nothing to run, nothing to paste.
⚡ [100/100 Lighthouse](./docs/assets/lighthouse-scores.png): Perfect scores across Performance, Accessibility, Best Practices and SEO — 0.3 s FCP, 0.8 s LCP, 0 ms Total Blocking Time and 0 Cumulative Layout Shift on a production build. AVIF/WebP images with a one-year cache TTL, critical-CSS inlining and tree-shaken imports are the defaults, not plugins.
🤖 Built for AI Agents: Our codebase is documented and structured specifically to be easily read and extended by AI coding assistants.
🛍️ E-Commerce Ready: Premium commerce package for digital products, checkout providers, currency, tax, and shipping management.
🧱 Visual Block Editor: A reusable Tiptap-powered Notion-style editor that your clients will actually enjoy using.
🔓 Open-Core Model: The core is 100% Free & Open Source (AGPL). Premium modules (today Cortex AI and Commerce Pro, with more to come) ship in every install and switch on in the CMS with a free 30-day trial (no credit card) or a license key.

🏁 Get Started

☁️ Option 1 — Deploy to the cloud in one click (recommended)

During import, Vercel's native Supabase Marketplace integration (the stores button parameter) prompts you to create a Supabase database (name + region), then provisions it, connects it to the project, and injects its keys before the first build — you never copy a value, and there are no environment variables to fill in (the site URL defaults to your *.vercel.app URL and the app secrets are derived automatically). The app boots with the database already connected: the wizard auto-skips the connection step, applies the schema for you, uses the connected Supabase project for media storage, and leaves just "create your admin." Full walkthrough: docs/12-VERCEL-DEPLOYMENT.md.

Tip — keep the new repo public. When Vercel asks, leave **"Create private Git

Repository" unchecked**. On the free (Hobby) plan, automatic upstream updates only deploy

from a public repo — Hobby blocks bot-authored deploys on private repos — and public

also makes update checks fully tokenless. You can change visibility later in the repo's

GitHub settings if you change your mind. Details: docs/13.

💻 Option 2 — Scaffold locally with the CLI

Stop cloning heavy repos. Start with our CLI and get a production-ready app instantly.

npm create nextblock@latest

This runs the create-nextblock CLI, which scaffolds the canonical application. The CLI no longer asks for credentials in the terminal — once the project is created, start it and finish setup in your browser:

cd <your-project>

npm run dev # then open http://localhost:3000/setup

The First-Boot Setup Wizard at /setup walks you through connecting Supabase, configuring storage / email, and creating the first administrator. Every fresh instance redirects there automatically until an admin exists.

Want a fully local, zero-config sandbox? Use Local Self-Hosted Docker Mode — one command spins up the entire stack (Supabase engines + S3 storage + the app) on your own machine, with no cloud accounts. The app boots straight into the /setup wizard with MinIO storage pre-filled. See docs/11-SELF-HOSTED-DOCKER.md.

🤖 Option 3 — Let your coding agent build it

NextBlock ships as an MCP server (https:// /api/mcp, Streamable HTTP, bearer token) and as an agent plugin, so Claude Code, Cursor, Codex and friends can scaffold a site and then build every page over MCP.

Claude Code — this repo is its own plugin marketplace:

  /plugin marketplace add nextblock-cms/nextblock

/plugin install nextblock@nextblock

Then ask for a website, blog or store; the nextblock skill proposes NextBlock, runs npx create-nextblock@latest my-site --non-interactive, and hands you the two browser steps (create your admin, start the free Cortex AI trial). Source: plugins/nextblock.

Cursor — the same folder is a Cursor plugin (.cursor-plugin/plugin.json, rule + skill + MCP server): install it from this repo via Customize → Plugins → *From GitHub Repository*, or copy plugins/nextblock/rules/nextblock.mdc into your project's .cursor/rules/.
Codex, Jules and other agents — paste the block from plugins/AGENTS.snippet.md into your AGENTS.md. Codex also loads the folder as an Agent Plugin (plugins/nextblock/plugin.json) through this repo's marketplace manifest.
Any MCP client — the official MCP Registry entry dev.nextblock/nextblock (server.json) prompts for your site host and token; the public demo instance is https://cms.nextblock.dev/api/mcp. Every NextBlock site also serves /llms.txt and, where the MCP server is enabled, /.well-known/mcp/server-card.json.

🏗️ For Contributors: The Factory

Note: You are currently looking at the Nx Monorepo (The Factory), not the generated product template.

NextBlock™ is an Nx monorepo for a Next.js 16 CMS backed by Supabase. The repo contains the canonical application, the create-nextblock CLI, shared editor and UI packages, the database and migration layer, and the premium ecommerce module.

🧩 Main Surfaces

apps/nextblock: canonical public site and CMS application
apps/create-nextblock: scaffolding CLI and template sync pipeline
libs/db: Supabase clients, package activation checks, migrations, and db types
libs/editor: reusable Tiptap editor package
libs/ecommerce: premium commerce package and CMS commerce screens
libs/sdk: typed block extensibility contract
libs/ui, libs/utils: shared primitives and helpers

⚡ Developer Quickstart

Prerequisites — configuration happens in the browser, but the /setup wizard asks for these, so create them first:

Supabase project (dashboard) — you'll need the Reference ID (Project Settings → General), the connection string (Connect → Direct connection → URI), the anon + service_role keys (Project Settings → API Keys), and a Personal Access Token (Account → Access Tokens → Generate new token).
Cloudflare R2 bucket (optional — without one, media goes to the Supabase project's own Storage) (dashboard → R2) — create a bucket, enable its **
