From https://github.com/redwoodjs/redwood/blob/main/README.md:

> Redwood is an opinionated, full-stack, JavaScript/TypeScript web application framework

> A Redwood application is split into two parts: a frontend and a backend. This is represented as two JS/TS projects within a single monorepo.

> The api side is an implementation of a GraphQL API.

Not sure you'd want to choose this if you want to roll your own API (without taking advantage of the framework/integration).

Thanks, though what I'm looking for (and, I expect, many/most other developers too), is a simple statement of whether I can write my backend in Go, Java, python, node, etc.
