Best alternatives to NextBlock CMS in 2026
Most content management systems were built years before AI coding agents existed, which means their code isn't organized in a way that's easy for an agent to read and extend — you end up fighting the CMS's assumptions as much as building your site. NextBlock was designed the opposite way: as a modern, open-source CMS built specifically for Next.js 16, with a codebase structured so both human developers and AI agents can navigate and extend it. NextBlock combines a visual, Tiptap-powered block editor with the performance of Next.js React Server Components, backed by a Supabase PostgreSQL database that stores content as JSONB blocks. It claims 100/100 Lighthouse scores by default, supports one-click deployment to Vercel or a local self-hosted Docker setup, and includes built-in e-commerce (digital products, checkout, currency, tax, and shipping) alongside a custom block SDK for extending the editor. It positions itself as an open-source, developer-first alternative to WordPress, Payload, and Strapi, and is licensed AGPL-3.0-or-later.
