Ryver

Comments: We switched to Ryver when Slack changed its pricing structure. It seemed clunky at first, but they've continued to run updates a couple times since then and it's gotten better.
Simple, graphically trimmed chat service.

Pros: It's a familiar set up and functionality to anyone who's used Slack in the past.
Does a great job of helping our company communicate.
No storage issues uploading images to share them on the platform.
Recently started to utilize the task functions, big plus.

Cons: Responding to a comment and creating a thread is NOT conducive to quick, multi user conversation. The reply carries below it a ghostly version of the full message it relates to. Makes for a very cluttered stream of communication.
Preloaded "Task" categories (Trello-like set up) are unnecessary and get cleaned every time to replace them with my own.
Administrators/creators of channels/teams/forums have ultimate control and cannot reassign their authority when they leave the channel. Inconvenient.

Comments: I would recommend Ryver to everyone because it helps manage your team. You discuss important facts about a task and project and also get to assign task and as well check when completed. It promotes accountability.

Pros: First. I must say, Ryver is a great alternative to slack and its free. It's a messaging app that let's you manage task and projects. You get to chat one on one or in groups. As a freelancer, Ryver is an app I hold dearly because it has helped me interact with team, as I get to assign task to them and also talk about any part of the task that's difficult to handle.

Cons: Logging into the App can take awhile. The developers should work on this. I have no other problem with Ryver.

Comments: Slack is great for organisations collaboration

Pros: Its decent compared to Slack or rocket
Its easy to use
Its Free to use and you can have unlimited users
Sharing files is as easy as drag and drop
you can integrate third party services like Trello

Cons: The software logs you out after it updates,
when you make a call it sometimes doesn't hang up

Comments: Ryver has been a great addition to our stack. It's free so it lets us really dig in on every feature to maximize the fact that it's free! There have been several major releases that were communicated well and added major value. I have been very pleased with my interactions at all levels.

Pros: It's an amazing alternative to the other communication platforms out there. You already know how to use it. It's fun, simple, and gets the job done!
Even comes with a pretty solid trello board to keep your tasks in line.

Cons: It's not as sexy as Slack - There I said it! :)
Once you are in a system you can't leave. Like all these platforms. Once you commit - You are in!

Comments: I didn't miss slack when I switched over to Ryver. I was getting the same features with additional task function as well as complete access to old messages.

Pros: Unlike Slack, You can retain messages forever as a free user (No loss of old messages to newly added team members). The task tab is an amazing feature which lets you assign a task to individual members of the team as well as set a deadline in which the task is supposed to be completed.

Cons: Replying messages in a team channel is very messy, they carry the complete messages previously relating to it and this is not pleasant to the eyes in any way.
