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.

Pumble

Communication with my team is much smoother, and it has helped me save time and better organize projects. I also appreciate the excellent customer support, which is quick and effective.

Program Manager

Luckily, we stumbled across Pumble, and it's perfect. It does everything Slack does, but for free.

President

I loved the user friendliness of Pumble and it is much better compared to other products.

News database administrator

UI a UX of the app is awesome. Mostly because it is so similiar to Slack so if you are satisfied with Slack then you will also like Pumble.

Digital Marketing Manager

I love this tool and am so glad that Clockify nudged me about its creation.

Marketing Specialist

It's easy to use and very friendly, good value for money, for what it offers.

Architect

The fantastic experience that this software gave us make us try Pumble, which mostly covers our needs. Would be great if "Clockify" and "Pumble" could synchronize together.

I enjoy using Pumble to communicate effectively with my coworkers throughout the workday. It's easy to navigate and simple to use.

Professional

Ease of use and good features are the unique aspects of this platform.

Head of IT

The paid subscriptions also seem very reasonably priced, so I would highly recommend Pumble as an excellent alternative to Slack.

This software is free with unlimited users and messages. Is very easy to use and it's focused on productivity.

founder & director technology 

Often slows down by end of day (desktop product) and has to be killed and restarted.

It is still new and some features are missing.

Beatmaker

What I don't like is the lack of integration with external systems and also the fact that we cannot preview the files.

Inability to do voice/video calls. You can't get a link to a specific message/thread.

Things I liked the most is actually communication with support team.

Good software for small organization but lacks diff tools integration.

Seasonal Benefits Counselor

While it lacks some advanced integrations and large-scale video conferencing capabilities, it excels in core communication features.
