What are the good tools to build Admin UI based on REST / GraphQL?

I am looking for tools or frameworks that are great at taking REST / GraphQL endpoints and help in making sleek Admin UI as fast as possible.

To avoid XY Problem. I have access to REST / GraphQL but I can’t access the DB directly. Hence I can’t use a $name headless CMS.

Tools like Hasura or Postgraphile are amazing tools that generate REST / GraphQL API to a database. db -> REST / GrapQL

Headless CMS like Directus (my favorite) or Strapi are amazing in providing Admin UI on top of SQL DB. db -> Admin UI + REST & GraphQL

I am looking for something that would do this: REST & GraphQL -> Admin UI

It feels like there are some tools that do that, but I don’t know anyone who has experience with any of them.

Anyone has any ideas or recommendations? Would prefer to have an option to add custom code too.

Free, cheap, open source or self hosted would be the best >:)

Some tools that claim to do what I need, but not sure about it
