Strapi

Strapi is an open-source headless CMS built with JavaScript and TypeScript, giving you full control over how content is stored and served. You can define custom data models, build custom APIs, and connect to any frontend or third-party service you like. It's self-hosted, so you're not locked into a vendor platform.

Strapi appeals to developers and technical teams who want flexibility that Airtable or Notion can't offer. You can integrate it with Airtable for hybrid workflows if needed, and you keep your data and logic fully customizable. It's heavier to set up than drag-and-drop tools but gives you the foundation to build exactly what you need.
