Which modern online booking system to choose?

Question

CMS

Good afternoon.
I am looking for a universal web-based system for online booking. I tried several freeware options on php + mysql. I didn’t find any universal ones, basically the systems are tailored either to the schedule, where the user selects a free date and enters his event, or online booking of tickets. In addition, such products are mostly abandoned, they have a very outdated design. Some required mandatory registration for customers (people who want to book something).
I need something similar to phobia.ru . I tried the Timeliner demo , everything seems to be fine, but the prices for small businesses are very high (33,000 rubles a year).
Watched demo of Time Slots Booking Calendar— almost everything is cool, the price suits. The only embarrassing thing is that it is not clear whether it is possible to show a summary table for all rooms. You can't test until you buy.
Maybe someone will tell you a system that allows you to introduce a sign on the site like on Fobia.ru?

• unlimited number of rooms
  
• slot duration setting
  
• output with a summary table (rooms / time) and output with a detailed table for each room for 1-2 weeks in advance
  
• no registration required to make a reservation, you only need to leave your name and phone number
  

Ready to buy such a system. I do not want to get involved in the development of my own product.

Answer 1

I think that such a system will be done on freelance from a couple of days to a maximum of a week.
The main thing is to clearly formulate the requirements for appearance and functionality.

Answer 2

I recommend using the cloud -based online booking system
