Strapi is more than a CMS, it gives a strong base for an API with a beautiful admin UI. A match in heaven combined with NuxtJS.
Having chosen to develop sites with NuxtJS, I sought an open source, self-hosted, Node-based, GraphQL-compatible back-end to complete my decoupled stack. As far as I know, the only such product in the world is Strapi! So thank goodness the product is smart and keeps improving, the team is on fire, and the community is excited.
