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.

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 database—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.
