IMCore vs Rocket.Chat: picking your self-hosted messaging stack
Rocket.Chat is a long-standing open-source IM with a free self-hosted Community edition, strongest at team collaboration channels and omnichannel; IMCore is a messaging engine plus customer-service suite that deploys as a single Go binary, built for teams embedding chat into their own products. Both self-host — the decision is about scope, not whether you can install it.

How does IMCore scale?
Start with a single binary on one machine; from the Pro edition onward, IMCore scales horizontally across instances over a message queue for production volumes.
Can IMCore be used as an internal team chat?
You can, but IMCore is designed to embed chat into your own product (app, site, mini-program); for pure internal collaboration Rocket.Chat is the better fit.
How is IMCore licensed?
The Basic edition is free to download and run; Pro, Customer Service and Enterprise editions are yearly or one-time buyout, with client UIKit shipped in commercial editions — see the pricing page.
