A very basic REST service for JSON data – enough for prototyping and MVPs!

Features:

no need to set up a database, all data is managed automagically*
REST paradigm CRUD for multiple entities/namespaces
schema validation
search using jq like syntax (see https://stedolan.github.io/jq/manual/)
CORS enabled
easy to deploy as container

* you can use an in-memory data approach with zero config or postgres as database, you just need an instance running, no queries…
