What does Rocket.Chat do well? Rocket.Chat has great documentation, very powerful to customise and make it your own. Integrates well with many platforms and can be used to replace almost any current solution with little adjustment time. The live chat feature is great, implementing this with other providers is overly complicated compared.
What does Rocket.Chat not do well? Nothing but pricing can be seen as expensive if you are looking for a cloud-based solution. Also, the whole pricing side of things can be a bit confusing until explained. The need to manage this as an additional service outside of the current technology stack adds another concern.
What do you wish you had known about Rocket.Chat before using? Give it a try, you won't regret it, the platform looks overly complicated to configure but actually has great documentation and can be customised to fit your business. The reason we found it was because of the live chat functionality on the website.
