Directus connected to a Postgres database

Comes with a built-in low-config UI/API for CRUD on the database, and easily extendable with Vue.js and Express endpoints.

Additionally, should the need arise for something more custom later on, all your data is in Postgres rather than a backend as a service

I've used it on a project a year ago and I've found it very effective for prototyping. But I eventually had to move out of it, and I don't see good you can make it work in the long run, as access management and data migrations are a PITA.
