Is there an analogue of R-Keeper?

Question

Iron

Good afternoon dear experts. I would like to ask you a question about the R-Keeper system.
Are there any analogues of the R-Keeper system? So that I can put this system in a small cafe? Or ... maybe there is something similar or approximately similar to this system? Preferably as a web application. Thank you! I would be very grateful to all of you for your help and for any tips on this issue.
