Best Free Slack alternatives

More than 12 million people wake up each morning and start their working day by opening Slack. Nowadays, when many companies shift their employees to remote working places, this app occupies one of the leading positions among team collaboration tools, maintaining contact between team members, simplifying their work, and boosting productivity. Although convenient and fast, Slack has some drawbacks. Today remote teams are looking for easier and more affordable services that satisfy their requirements. If you’re one of those people, take a look at our list of ten free alternatives to Slack.

Best Free Slack alternatives

Why do people use Slack?

With Slack, we forget about long and messy email threads, ordinary calls, and meetings in an office with a whiteboard and a round table with everyone gathered around it. The platform lets workers stay in contact with their teams, distribute various documents and files in one tap, use built-in integrations with other services, and store information in cloud storage - everything completely different from traditional means of communication. 

To prove Slack’s popularity and figure out the reasons for it, our team conducted a survey, where we asked respondents to tell why they choose Slack over other alternative clients. As a result, they highlighted three main arguments for using it:

1. It’s trendy

After talking to a couple of CEOs and hundreds of managers from different enterprises of various sizes and industries, it becomes clear that they all love Slack or at least know everything about it. This platform has this air of being cool thanks to various cutting-edge features, like smart bots or the possibility to create your own channel. But in general, the most popular answer to the question “Why do you use Slack?” was “It’s cool and everyone uses it”.

2. Integrations with other services

While using Slack, you can connect it to more than 2,400 other apps your company uses daily, from Dropbox to GitHub. If you don’t know what is so great about being able to do this, let us explain. At work, you may use Zendesk, Salesforce, different kinds of CRMs, or cloud storage like Google Drive. To stay informed about all the updates, you may integrate other platforms with Slack and receive notifications there in real-time, without having to open each app separately.

3. Powerful search

Working in a company always means tons of messages, doubling daily. To navigate through all these texts, Slack allows searching among chats and files, even looking for some particular content within documents. What is more, if you share some files from Dropbox or Google Docs, you can also search through them. Unfortunately, a free plan allows storing only 10,000 messages in one private or team chat, but paid plans set no limits on the message history.

These three reasons and the overall service effectiveness keep users tied to the platform. 

But what about other apps similar to Slack? Are there any better solutions for business?
