Hey @tim15 , I haven’t used Tadabase but I have built some rather complex applications in Knack. Anything you can build natively in Knack can be built better (much better) in Bubble.
The biggest thing to remember is that in Bubble you have to build every piece of every element.
Whereas in Knack you can just drag a table onto the canvas, tell it what datatype to source, the conditions you want that data filtered by, click the fields you want to display, and off you go with filtering, sorting, etc all built-in.
In Bubble you will build every piece of that table… header, rows, sorting actions, searches, filters, pagination, etc.
But with granularity comes much power! Compared to the search and data manipulation limitations of Knack you will feel like a superhero in Bubble.
2 cents from a former fellow Knack builder.
