Not present

NextBlockโ„ข CMS is a high-performance, developer-first, open-source platform built natively for full-stack environments. Unlike decoupled headless architectures that force schema duplication, API mapping bottlenecks, and separate repository management, NextBlock delivers a unified framework. It pairs a fluid editorial canvas with a built-in Next.js 16 and Supabase/PostgreSQL architecture to achieve perfect 100/100 Lighthouse performance scores by default.

Core Architecture & Key Features:

  • Tiptap Block Editor: A slash-command, Notion-style visual canvas that saves documents as strict, node-based JSONB directly into your databaseโ€”completely bypassing raw HTML formatting mess.
  • Dynamic Schema Engine: Configure, edit, and duplicate custom block widgets on the fly. Layout definitions are live database fields injected at runtime, requiring zero code changes and zero Vercel redeploys.
  • Cortex AI (BYOK): A premium orchestration layer. Bring your own OpenRouter keys to eliminate SaaS markups. Uses constrained decoding to generate perfectly structured layout blocks or globally manipulate workspace settings via the dashboard.
  • Hybrid E-commerce: Built-in multi-currency monetizing mechanics mapping physical goods through Stripe (with global auto-tax sync) and digital software licensing natively via Freemius.
  • Native i18n Middleware: Localized routing is built into Next.js edge middleware, processing header variants instantly without hydration lag or heavy runtime bundle bloat.

  • Tech Stack: Next.js 16 (App Router), Supabase/Postgres, Tailwind CSS, Nx Monorepo, Turbopack.

  • License: 100% Open-Core under AGPLv3.

  • My blog post workflow
    Next, Iโ€™ll copy and paste the draft text to my CMS. Iโ€™ve been using Contentful since working there in 2021.

  • How to Style Markdown in Next.JS Using React-Markdown and SASS
    If you have a blog or website with articles or long text documents, markdown is your friend. It makes authoring documents so much easier and more intuitive than straight HTML. Markdown has a far smaller learning curve than HTML and can easily be taught to non-tech-savvy writers. Markdown editors are also built-in to headless CMSs like Contentful. - Source: dev.to / almost 4 years ago
  • Looking to Create a Wordpress Style Website with Python / Flask
    It depends on the requirements, but this might actually call for a headless CMS like Forestry.io or Contentful coupled with a Static Site Generator like Hugo. The CMS will manage users/permissions/data hierarchy and provide a simple frontend for users to add content, lay out pages, etc. And then when they save a change, the SSG will re-run and render everything to static HTML/CSS/JS.

  • How to Create a Blog Using Next.js and Contentful CMS
    Contentful is a headless content management system (CMS). Headless simply means there is no front-end to display the content to the consumer. It's basically a database, but much easier to setup and maintain than a traditional relational database. Contentful provides a very easy-to-use API for fetching and managing content. They also support GraphQL queries if you're into that. - Source: dev.to / about 4 years ago
