There's no denying the popularity of Slack. Over half a million people around the world rely on Slack to communicate with their colleagues, collaborate on projects, and carry out meaningful work.

When something’s as popular as Slack, it’s easy to ignore alternatives.

Slack has a lot going for it, but it's far from perfect. There are a lot of downsides to Slack, leading to teams seeking a better, more suitable service.

If you're looking for an alternative to Slack, here are eight options you should know about, along with key features and why you might consider them instead of Slack.

Microsoft Teams

Although it might lack the coolness factor of Slack, Microsoft remains a core part of the work environment for people around the world.

Microsoft Teams, a Slack alternative that forms part of the Microsoft Office environment, actually overtook Slack by many metrics, leading to a lot of media coverage.


So what are the reasons to use Microsoft Teams instead of Slack?

Integrated with MS Office 365. If your company is already using Microsoft Office products, it makes sense to use the built-in Microsoft Teams functionality. Otherwise, you risk inefficiency due to switching back and forth between different app environments.

Threaded Messages. One complaint from some Slack users is the app can feel a little chaotic and disorganized. Microsoft Teams has the capability for threaded messages, which many people feel leads to a tidier and more organized environment than Slack provides.

Meeting Scheduling. If you've taken the time to get a feel for the experience of using Slack, you may well have noticed that it often leads to a lot of discussions that fail to translate into actionable steps. With Microsoft Teams, you can schedule meetings directly, ensuring that moments of inspiration don't end up being wasted through inaction.

 Integrated Voice and Video Calling. There's no one perfect form of communication for every team out there. Some situations lend themselves to video calls, other times a voice chat is enough. Microsoft Teams gives you the choice of both methods, allowing your team to communicate in the way that they prefer.

Why You Should Consider Microsoft Teams Over Slack

The main reason to select Microsoft Teams for your collaboration and communication instead of Slack is if your team is already heavily invested in the Microsoft ecosystem. If everyone is using MS Office as standard, it makes a lot of sense to choose Microsoft Teams as your Slack alternative.

Troop Messenger

Troop Messenger is a communication app aimed at organizations of every type and size, from small businesses through to government and defense. 

Let’s explore what Troop Messenger has to offer the world of specialist communication software. 


Which Troop Messenger features make it particularly appealing when compared with Slack?

Burnout Window. Depending on the nature of a project, and the types of messages needed to complete it, it might not always be desirable to leave a permanent record. If you're looking for a discreet way to message, Troop Messenger's Burnout Window might be the perfect solution. Consider it your way to send incognito messages – for whatever reason.

Forkout. Sometimes, the biggest inefficiencies in business communication come from having to relay the same information to different people, and different groups of people. With Forkout from Troop Messenger, you can specify exactly where a message ends up at the time of sending – saving you the wasted time of copying and pasting it into multiple chats.

Custom Messaging. Not every situation requires the same type of message. With Troop Messenger, you can send audio messages, often a quicker way to convey thoughts in some situations. You can also recall a message, avoiding the awkwardness of the ‘edited’ tag showing up on Slack. Troop Messenger also makes it easier to mute certain chats compared to Slack. 

Why You Should Consider Troop Messenger Over Slack

If you're running a governmental, NGO, or another specialist type of organization specifically catered to by Troop Messenger, you should definitely consider it carefully compared to Slack. 

The free version of Troop Messenger also provides more storage capacity than Slack.

Don't Choose Slack Just Because It's Popular

You now see that there is a wide range of alternatives to Slack out there.

While Slack is a great solution for many organizations and teams, it shouldn't automatically become your default choice without considering other options.

Think about the features that matter most to your company, and weigh up the costs and benefits of using Slack or another option.

Consideration Points For Evaluating Slack Alternatives

So what are some of the actionable steps you can take to evaluate whether to opt for Slack or an alternative solution? Weigh up the pros and cons of Slack compared to other apps in the following areas:

  • Cost.  How much will you have to spend on your intended communication and collaboration platform? Is there a free version? How limited is it? If you want to expand or shrink your team in the future, how will this impact on cost?
  • Capacity. Does your intended solution have a restricted capacity in any way? For example, does it limit the number of messages? Storage? Any other restrictions? If you want to overcome these restrictions, does the platform make it possible?
  • Security. What level of security do you require? Do you want a privately hosted platform? What form of encryption are you comfortable with?
  • Communication Methods. What type of communication does your team want to utilize? Do you need video calling, or the ability to call phone numbers?
  • Collaboration Capabilities. Do you need compatibility with a certain number of file types? What about screen share and whiteboard collaboration?

By getting clear on the above points, you equip yourself with the information needed to make an informed choice about whether Slack is the right choice for your organization.
