Visual Drag Drop Web App Builder (Database system similar to MS ACCESS)

Im looking for a free or cheap (not pay monthly) app that i can use to build apps similar to how MS Access works with tables and forms and relations ecc.. don't need anything complicated but i do have to pull data from multiple tables in different forms ecc.. I have basic coding knowledge so it has to be low/no code and visually able to create forms and other things in the design part.

If i can self host its better, if its free its better, the easier to use the better. I mostly help out very small businesses or startups with low or no budget and during these difficult times i am trying to be part of the solution for a lot of small businesses in need of some IT problem solving.

Any help appreciated and thanks in advance.
