Our verdict on NextBlock CMS
NextBlock CMS is an open-source content management system for building and operating Next.js websites, aimed at developers who want AI-assisted page creation and control over deployment. Its visual Tiptap-powered block editor works with typed JSONB content stored in Supabase PostgreSQL. Editors can manage drafts and revisions, publish without rebuilds, run SEO checks, and translate content by block. This is a CMS for teams shaping their own site stack, rather than a turnkey hosted website builder.
AI-generated full-page layouts are a distinctive part of the workflow: the Cortex AI layer connects external agents such as Claude Code, Cursor, ChatGPT, and Gemini through MCP to produce structured layouts. The product also connects with Vercel and Cloudflare R2, and supports one-click Vercel deployment or self-hosted Docker deployment. The flexibility suits developers who want an agent-assisted content workflow and are comfortable choosing and operating infrastructure. Buyers looking for an all-in-one builder with hosting included should look elsewhere.
The core CMS has a free plan, and the published offer includes a 30-day Cortex AI trial without requiring a card. The paid Cortex AI license price is not provided here, so teams should check that cost before depending on AI features long term. Optional commerce tools cover checkout, taxes, shipping, inventory, and orders, while Stripe is among the listed integrations. Support is through community and documentation. Choose NextBlock if open-source control, Next.js fit, and self-hosting matter; consider a hosted builder if minimizing infrastructure work is the priority.
