Internal.io does something similar and supports SQL Server (as well as MySql, Postgres, Snowflake, DynamoDB, MongoDB and more..). It's a bit more like Retool with the visual builder but easier to use without code. Comparison vid with Retool here: https://www.youtube.com/watch?v=7GgBnbHF8Rg

Full disclosure: I currently work for Internal but if you have any questions on our platform let me know!
