What is an alternative to attlassian products?

Question

Documentation

Good day to all, due to a change in the policy for providing products in standalone, namely, the cessation of product development, soon its support and the cessation of license sales, all that remains is a data-center, which can seem to be installed inside your company and A heavily promoted version of the cloud that didn't meet my company's requirements. Currently, the products in use are Jira and Confluence.

The question is, are there any alternatives that you currently use and are satisfied with the functionality and convenience?
Interested in various software options, it is important that you can install within the company, paid, shareware (cut functionality) and opensource, I will be very grateful for feedback on the products.
