NextBlock™ CMS

Full-stack engineer building NextBlock™ CMS — the high-performance, open-core alternative to WordPress. Currently architecting for the Next.js 16 and Supabase ecosystem. We’re pushing 100/100 Lighthouse scores by default and building a native AI-agent layer (Cortex AI) that understands your database schema. Sharing everything about our AGPL open-core journey and open beta.

Currently $0 MRR — we are prioritizing community feedback and 'breaker' testing over revenue during our beta phase. Check out our public sandbox at nextblock.dev.


NextBlock™ CMS (Core): The high-performance, open-core alternative to WordPress.

A full-stack (not headless) CMS platform built for the Next.js 16 and Supabase ecosystem. NextBlock combines a Notion-style Tiptap block editor with React Server Components to deliver 100/100 Lighthouse scores by default. The core is 100% open-source under the AGPL license, designed for developers who want ultimate performance without the complexity of decoupled headless architectures.

Current Status: Open Beta. We are currently inviting "breaker" testers to explore our public sandbox (which resets every 15 minutes) and provide feedback on our Next.js 16 caching logic.

  1. Premium E-commerce Package

    Multi-currency commerce with automated global tax compliance. A professional-grade commerce module that bridges the gap between physical and digital sales. We utilize Stripe for physical goods (leveraging native auto-tax sync) and Freemius for digital license management. Features include multi-currency support out of the box and a unified sales ledger that integrates directly with your CMS content to track which pages drive the most revenue.

  2. Cortex AI Package (Premium)

    AI-native orchestration with "Bring Your Own Key" (BYOK) architecture. Beyond simple chatbots, Cortex AI is a native agent layer built into the CMS dashboard. It uses constrained decoding to generate strict JSONB blocks that insert directly into the database without breaking your schema. Our BYOK architecture via OpenRouter allows developers to use their own API keys, bypassing traditional SaaS markups while enabling global database querying and system orchestration.
