I would like to add Budibase to this list.

The platform is open source, makes it incredibly easy to build internal tools, SSO is free, and its apps are responsive. Also, coding is optional (unlike other platforms listed in this thread)

Also, Budibase is currently free!

I'd like to highlight Budibase's incredible cloud platform - it's now 100% the easiest and most intuitive way to build business apps and internal tools.
