Staying connected is the first rule of thumb for remote teams.

Due to the coronavirus disruption, we are forced to lead a remote life, be it shopping, working, or interacting with friends and colleagues. During these uncertain times, a slight deviation from focus can momentarily reduce productivity, especially for team collaborations.

Hence, it’s essential to utilize a good tool for better communication. While there are many channels available that foster a collaborative environment like emails, phone calls, shared tasks, and virtual meetings, instant messaging is indispensable.


Real-time messaging

The best thing about messaging platforms probably is that they facilitate real-time messaging. As a result, it accelerates response time to keep your team members “close” and leads to better decision-making.

Also, when you put people on the spot through call or video conferencing, decision-making might be compromised as it may pose pressure on the recipient.

But, messaging platforms uplift this pressure by giving them a few precious seconds when they can process their thoughts, formulate their response, and come to a decision best for your entire discussion.


Transparency is crucial to fostering productive teamwork. Messaging platforms cover this aspect by promoting flawless communication where everyone is approachable, just a message away. It breeds no ground for confusion or hesitancy.

These platforms are great because people can be clearer about their feedback, praises, support, and advice that help reinforce the goals and directions of your organization. It levels everyone and supports a team’s hierarchical nature.

Record Keeping

Chat histories, I tell you, can be saviors at times. You can review all the communication you had with your team, which helps in many ways.

Imagine you just had a discussion with your senior over a project. In case you missed a beat, you can still go back to the same chat and use the information for better clarity.

This, in turn, boosts performance and decreases the likelihood of errors.


cost effective

Instead of investing in overpriced phone call plans, expensive software, travel plans, and whatnot, you can simply go for messaging platforms. You can find both paid and free ones depending on your requirements.

Slack is one such messaging platform that people use these days extensively. The hype is due to its flexibility, features, and easy-to-use interface. And it is becoming bigger with time, especially after acquiring HipChat and Stride.

However, some aspects might land you in a boat where you may want to find an alternative solution to Slack.

  • Firstly, Slack offers too many features that you might not find necessary for your organization. So, what does the point have features you wouldn’t use?
  • Secondly, the cost. Options like Slack, Zoom, and Microsoft Teams are available out there but are costly and might not be the best fit for your company financially.

So, what’s the solution for your instant messaging requirements?

Open source messaging platforms!

But, here’s a catch. Open source can be critical for your business needs, especially when sensitive information is involved.

In this case, choosing a hosting solution for your open source messaging platform is the best option. That way, you can protect your communication and data behind a secure firewall.

For that matter, let’s look at some of the best Slack alternatives, along with corresponding hosting suggestions.
