Software Developer

The incoming hook limitation of maximum content length is the hell (Mattermost don't inform the customer about a message which was higher above the hard coded message size limit).

Marketing Manager

What I like the most about this collaboration software is the simple and logical UI, which is not overloaded with lots of unnecessary features. It has all we need for successful communication.

Cross-platform applications ready to use. Amazing open source community built around the product, friendly and helpful people.

CEO / Lead Architect

The software is easy to use, similar to the commercial app Slack. It provides good thread tracking and the interface is clean and easy to understand.

Scrum Master 

I like how easy is to use and allows different "rooms" for collaboration for teams. It is a great tool for fast daily communication.

IT Security Engineer

Can be hosted on-premise. Good community support - Apps and Integrations brings great support to exchange data with external systems for software development teams.

Chief Growth Officer

Mattermost is intuitive to use and easy to implement in your company. It has a good amount of integrations.

Technical Writer & Digital Marketing Specialist

Honestly, the most use we get out of this product is having fun with the wide range of emojis you can add to posts as reactions.

For its purpose, I have found nothing about the software that I can find to complain about.

Senior Developer

Running the software locally means you can keep a much better eye on its security and usage. Its user management and directory integration is superior to Slack's.

A bad user interface, a lot of bugs, sometime you need to restart it in order to make sure that everything works as expected.

Graphic Designer

That's a nice alternative to Slack. Managing channels and using the entire product is very easy and intuitive.

Head Of Design

It allows all our staff to quickly chat about things without clogging up inboxes or having them on their phones. Groups and channels are great, especially for management needs.

Software developer

Great for communication and to stay connected.

It is good collaborative tool as alternative to slack.

Accountant

When i receive message sometimes i miss notifications. When i click pop up window it doesn't begin conversation, i have to find message in contact list.

Software Engineer

Saved a lot of nerves and money, and vastly improved team communication.

Project Manager

I like the ability to build very specific groups and control notifications in each group. Was a previous Slack user but Slack doesn't fit with our security requirements and the cost.

President

The ease of deployment was the best feature. The administrative console was user friendly, and easy to navigate.

Medical practitioner 

It help to build a strong connection and good trust. Little bit get enjoy chatting through this software during office time.

Licensed Agent/Customer Service Representative

The only criticism that I have is that you cannot just delete unwanted old conversations. You have to leave the group and then it sends out an alert to the others.

Admin

Customer friendly and easy to use, find it friendly and interesting. Glad my company has selected office chat.

Secure way to send message to team overseas. Love the document attachment, emoji's are great.

Travel Agent 

Price is very good also. One thing I REALLY like is that it shows two green ticks once it has been delivered so that I know it has actually reached the other person and I dont need to follow it up.

Executive Officer

Finally, the live chat support is incredible. Chatting with a real person  who can walk you through any use of the product and takes your live feedback is outstanding, especially for the cost.

Designer

I like the ease of sending my coworkers messages that can be shorter than emails, especially because we are all remote.

We have had a great experience and wonderful integration.

Surgeon

It was a great integration product for our office.

Franchise Owner

I like the file-sharing capability and administrator settings.

Addictions Recovery Facilitatoy

Even if Office Chat is open as one of the other apps running in the background, it will minimize the other apps and impose itself for no apparent reason. Notably, I have an Android phone.

Cost Effective & Easy Solution To Keep Your Team In The Messaging Loop.

PT, Clinic Director

We like this to communicate in our therapy office, it is quick and easy to use.

Owner

Its reliable and easy to login. You can group people easily and review older messages.

Administrator

I love how easy it is to set up a user. There's no learning curve.

Business Coordinator

There are some glitches we have noticed. Sometimes the notification badge will appear when there is no new message.

Editor

When I was added to a pre-existing chat, I always had a notification for a new message even though there was no new message and I couldn’t get rid of that.
