What ready-made solutions can be used to organize communication between site users?

Question

API

We are building a web platform for online hackathons. It is necessary on the platform itself to organize the possibility of communication between participants with each other (PM and team chat), participants with experts, participants-organizers. We are looking at Slack, but we will be grateful for recommendations and other ready-made solutions.

If I were you, I would clarify what exactly the problem is. There are a lot of solutions - slack, cart, vk, own messenger, own chat, plug-ins, depends solely on the needs of your users and your own.
