react-admin
A frontend Framework for single-page applications on top of REST/GraphQL APIs, using TypeScript, React and Material Design
I've been working with react-admin on various projects, some of which required basic CMS features in addition to the core application. We've used headless CMS like Strapi, Directus, or Prismic for these features. However, react-admin is so powerful that it can be used to build the CMS part, too. That's why I worked on a CMS proof-of-concept using react-admin for the admin UI and Supabase (which provides a REST API) for the backend.

API Platform
🕸️ Create REST and GraphQL APIs, scaffold Jamstack webapps, stream changes in real-time.

> using the same language on the backend and frontend is underrated feature
I agree, but you can definitely do this without SSR or Next.JS. Common examples are tRPC, Zodios, or even just plain fetch calls with shared type definitions.
