An open-source full-stack CMS for Next.js and Supabase. Features a visual Tiptap block editor, strict JSONB schemas, edge internationalization, and perfect Lighthouse optimization.
A startup from Salaberry-de-Valleyfield, Canada, founded by Webman.
This page is designed to help you find out whether NextBlock.dev is good and if it is the right choice for you.
NextBlock™ 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.
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.

Insufficient information available
I do not have verified or reliable information about NextBlock.dev, as it appears to be a niche, new, or low-visibility product that isn't well documented in my training data. I cannot confirm specific pros without risking inaccurate information.
Elimination of the "Headless Tax" (vs. Strapi, Sanity, Contentful): Decoupled headless platforms force developers to maintain separate backend servers, duplicate TypeScript schemas, and endure third-party API latency. NextBlock bundles the data layer and frontend into a single Next.js monorepo with direct database queries.
Fast Developer Experience and Thin Runtime (vs. Payload CMS): Unlike Payload CMS, which requires hundreds of lines of collection config boilerplate and bundles heavy AST parsers (Lexical/Slate) that cause local dev lag and cold-start penalties, NextBlock provides an instant Tiptap editor and direct JSONB-to-RSC rendering.
Modern Performance and Security (vs. WordPress): WordPress relies on legacy PHP runtimes, vulnerable third-party plugin ecosystems, and bloated WYSIWYG editors that damage Core Web Vitals. NextBlock delivers guaranteed 100/100 Lighthouse scores, edge-first security via Supabase Row-Level Security, and a fluid Notion-style block editor.
No-Redeploy Marketing Agility: In conventional setups, marketing requests for new custom layout blocks require engineering sprints, code commits, and redeploys. NextBlock allows non-technical users and AI agents to create and publish custom blocks on the fly.
Frictionless Open-Core Ownership: The core framework is 100% open source under the AGPLv3 license, runs on free Vercel and Supabase tiers, and supports self-hosted Docker environments to avoid proprietary SaaS vendor lock-in.
Next.js and React Engineers: Full-stack developers who want a modern content platform built natively around Next.js 16, React Server Components, and Supabase without dealing with disconnected API layers.
Web Agencies and Dev Shops: Digital agencies managing client websites that want to eliminate recurring maintenance tickets, plugin vulnerabilities, and manual code changes for everyday page layouts.
Content Creators and Marketing Teams: Writers and editors seeking a modern, document-style writing experience with slash commands, drag-and-drop modular sections, and native multi-language (i18n) workflows without touching code.
Indie Hackers and Solopreneurs: Technical founders looking to launch fast marketing sites, documentation, or stores with turnkey deployment, built-in dual payments, and BYOK AI agent workflows.
NextBlock was created by Nicolas, a Canadian Armed Forces veteran and Lead Web Developer with over 10 years of experience managing IT agency operations and enterprise e-commerce platforms.
While building production systems with WordPress, Strapi, and custom Laravel backends, he consistently hit the developer experience friction of the "headless tax"—specifically schema duplication across frontend and backend codebases, third-party API latency waterfalls, and sluggish performance. Evaluating Payload CMS revealed heavy admin bundle overhead and cold-start delays, while legacy platforms required constant engineering intervention for minor marketing layout tweaks.
To solve these recurring bottlenecks, he built NextBlock as an open-core, all-in-one CMS integrated directly into Next.js 16 and Supabase. By replacing raw HTML storage with strict PostgreSQL JSONB schemas, NextBlock gave developers 100/100 Lighthouse defaults and zero-redeploy custom block generation while giving content teams an intuitive, Notion-style visual editor.
Next.js 16: App Router, React Server Components, Turbopack, and Edge Routing Middleware.
Supabase & PostgreSQL: Relational database layer leveraging strict JSONB storage, Row-Level Security, and pgcrypto encryption.
Tiptap (ProseMirror): Rich-text, block-based visual editor engine providing Notion-style slash commands and drag-and-drop capabilities.
Tailwind CSS: Utility-first styling system dynamically bound to database-backed CSS variables.
Nx Monorepo: Workspace management architecture organizing applications, database migrations, and shared libraries.
Vercel AI SDK & OpenRouter: Powers Cortex AI with constrained JSONB decoding across models like Claude 3.5 Sonnet, DeepSeek v3, and NVIDIA Nemotron.
Model Context Protocol (MCP): Exposes an HTTP/SSE MCP server endpoint enabling tool-calling from IDE agents like Claude Code, Cursor, and ChatGPT.
Stripe & Freemius: Integrated payment providers supporting physical merchandise with automated tax sync and digital software license orchestration.
Docker & MinIO: Self-hosted infrastructure support providing localized PostgreSQL and S3-compatible asset storage.
NextBlock is currently in free Open Beta with $0 MRR, deliberately offering all core and premium features freely to gather testing feedback rather than running a paid enterprise customer roster. Its current deployments, production users, and agency evaluators include:
NextBlock (nextblock.dev) – The core production deployment, running 100% natively on NextBlock CMS as its primary operational testbed and dog-fooding site.
External Open Beta Developers – Independent developers and early "breaker" testers deploying custom instances through 1-click Vercel templates, Docker, and terminal CLI scaffolding.
Noble House Media – A digital marketing and web agency evaluating NextBlock CMS to transition client portfolios away from WordPress.
Unified Full-Stack Architecture: Instead of operating as a decoupled headless CMS that requires managing separate repositories and handling API waterfalls, NextBlock co-locates the content engine and frontend directly inside the Next.js 16 App Router.
Strict PostgreSQL JSONB Storage: Content blocks are stored as structured JSONB nodes rather than raw HTML strings or heavy AST trees. React Server Components render these nodes directly into JSX without client-side parsing overhead, hydration mismatches, or dangerous HTML sanitization.
Dynamic Schema Engine (Zero Redeploys): Custom block definitions and design tokens are stored as database data definitions, enabling teams to build, edit, and duplicate custom UI widgets at runtime without code changes or CI/CD redeploys.
Native AI Orchestration (Cortex AI & MCP): Cortex AI utilizes constrained decoding to synthesize typed, valid JSONB blocks directly into PostgreSQL using a Bring Your Own Key (BYOK) OpenRouter setup. It also exposes a native Model Context Protocol (MCP) server for external tools like Cursor, Claude Code, and ChatGPT to safely mutate layouts and query data.
Default 100/100 Lighthouse Performance: Built-in edge caching loops, server-rendered components, and lightweight JSONB delivery guarantee perfect Core Web Vitals out of the box.
Built-in Hybrid E-Commerce: The platform includes native checkout infrastructure routing physical merchandise through Stripe (with automated global tax sync) and software licenses through Freemius from a single dashboard.
