I think charging for end users does make sense too in the context of building internal tools, it just means that other use cases (e.g. building public apps) is not possible.

Love retool! This new 5-seat plan will mean we can get started with Retool internally properly now on a trial basis, and hopefully upgrade in the future when we decide to roll it out!

(Although there do seem to be some bugs with the new plan - it keeps repeatedly telling me that i'm not licenced to edit things and that my trial is over so I can't quite start using it yet).

Also I can't use it for my personal projects as the commercial model doesn't quite work, so I use AppSmith for that.
