Are there any Bitrix 24 analogues?

Question

Computer networks

Good day!
Today, at work, the task is to have a service for the management or for the entire company, such as Bitrix24. Bitrix would also suit us, but the fact is that it can be used for a limited time and a limited circle of people (for free). But we need an analogue of such a service where large arrays of people can work at once and without time limits.
Are there analogues of Bitrix? or how can I solve the problem with a service of a similar plan

Answer 1

You can buy a boxed solution, pay once and use it.
There is a cloud solution free of charge and not limited in time and users. https://www.bitrix24.ru/prices/
It's not clear what you mean about time

Answer 2

There are plenty of analogues, AMOCRM, Megaplan, Terrasoft and dozens of others.
There are cloud and boxes (for deployment on their servers).
If you want to find something free for a large company, you can write your own CRM.
