Ask HN: Is there any embeddable REPL? Like RunKit, but for many languages

RunKit is great, and we have been using it on our api doc [1].

However, RunKit was acquired by Stripe and development seems to stop. For example, it’s slow to update to support new package versions [2] and it only supports nodejs, not other server side languages

Ideally, we want something like RunKit, but with active development / improvement and multi-language support.
