Slack has made quite a name for itself over the years. Starting out as an internal chat tool to keep a small team of gaming developers connected, Slack now boasts 38.8 million daily active users. That makes Slack the fastest-growing startup in history, not to mention one of the leading instant messaging apps for business.
But that doesn’t make Slack a one-size-fits-all platform. Whether you’re using it now or considering it for your business, it’s helpful to have some Slack alternatives in mind. Every team is different, and Slack may not be the best answer for you.
The Best Alternatives to Slack in 2024 for Team Collaboration
This is the golden age of communication, and there are loads of apps like Slack, each offering distinct capabilities to suit teams of all sizes and functions.
Below, I’ll help you sort through the best Slack alternatives for 2024, so you can make the best choice for your business.
1. Brosix
Why not start with what we know best? It’s our blog, after all! Brosix is a highly capable, secure, and customizable Slack alternative.
Brosix enables team communication via one-on-one text chats, group chat rooms, and seamless voice and video chat features. Our user-friendly user interface (UI) lets you share your screen, capture instant screenshots, transfer files, and create whiteboard conferences, all with just a click.

We recently compared Teams vs Slack in depth. Check it out!
“At Ling, we use various digital tools for communication, collaboration, and project management. The lack of face-to-face interaction makes it difficult to build team rapport. Microsoft Teams has helped us get through this.
We created chat rooms for specific purposes, like ‘Content Development’ for content planning and ‘Water Coolers’ for greetings, small talks, and sharing mottos and personal and work wins. We also have set up a dedicated channel for our DEI initiatives to address communication and work relationship gaps due to cultural differences. All of these contribute to our employees’ sense of belonging and boost productivity levels while building a strong, cohesive work culture.” — Simon Bacher, CEO and Co-Founder, Ling

Lately, Discord’s rich voice features, coupled with chat capabilities and screen sharing, have begun to take hold in the business world.
Discord organizes conversations into ‘Servers.’ Servers are separated by text and voice. The latter continuously takes place in the background, and by clicking on a channel, you’ll immediately start voice communication with other users.
See our Discord vs Slack review for an in-depth comparison.

7. Ryver
We mentioned Trello as one of our top productivity apps. What’s that got to do with Ryver, you ask? Well, imagine the Kanban boards of Trello together with a team messaging platform, and you’ve got Ryver.

In addition to direct and group messaging, there’s a news feed, personal pages, posts, comments, and likes.

10. Twist
Twist was created by a team working remotely across several time zones. Their priority was to design a team chat app to better organize the asynchronous communication typical with remote teams.
In this way, Twist organizes messages into an inbox where they’re threaded by topic, so responses don’t get buried in endless streams of conversation.
You get direct and group messaging, threaded conversations, highly customizable notifications, browseable and searchable conversation histories, and a handful of integrations.
If you need voice and video, you’ll need to look elsewhere, as Twist doesn’t offer those.
“Twist’s unique threaded chats significantly boost team attention and clarity. Unlike standard chat apps, where messages can become lost in a never-ending stream, Twist arranges discussions by topic. This format allows our team to readily follow and respond to conversations, even across time zones. For example, our marketing staff in Europe may easily continue a conversation that began in Australia hours earlier without losing any important details.” — Sergey Taver, Marketing Manager, Precision Watches
Top Twist features:
- Native integration with Todoist, an app we’ve written about to help you stay organized
- Preview messages before opening them
- Have access to all your messages in an inbox
- Invite guests like freelancers and consultants
Twist pricing: Free version with up to 5 integrations, 5 GB of storage, and one-month message and comment history; $6 per user/month for unlimited everything
Pros and cons
| Twist Pros | Twist Cons |
| Organizes conversations into threads, which helps keep discussions organized and easy to follow, reducing information overload | May lack some advanced features and integrations found in other collaboration tools |
| Designed for asynchronous communication, allowing team members to respond at their own pace, which can improve productivity. | The unique thread-based approach can be challenging to get used to for teams accustomed to other communication methods |
| Offers a clean, minimalist interface that reduces distractions and helps business teams focus on their work |
Available on: Windows, macOS, iOS, Android, Linux, Web
User ratings:
- Trustpilot 3.8 (Stars) from 3 people
- Capterra 4.3 (Stars) from 36 people
- G2 3.9 (Stars) from 19 people
Why Do People Choose Slack?
People use Slack for the integrations. According to Slack, the chat software connects with more than 2,000 other tools and apps.
Slack delivers a social-media-like user experience through a hip interface that’s filled with notifications, emojis, GIFs, memes, and other such goodies. Slack also makes strong use of user feedback, taking customer suggestions on board in order to grow more iteratively.
Why Look for Slack Alternatives for Team Communication and Productivity?
Slack’s success and popularity are undisputed. The same goes for Slack’s top-dog status in the integrations category.
That said, those integrations render many of Slack’s capabilities a result of other apps and technologies. And if your team isn’t making use of those integrations, you’re practically pouring money down the drain, because Slack isn’t cheap.
- It’s expensive: At $7.25 per user/month for Pro and $12.50 per user/month for Business+, Slack is out of reach for many startups or small to medium-sized enterprises. There’s a freemium version, but that limits you to only 10 integrations and 90 days of message history and shared file storage.
- It’s complicated and disruptive: If you’re part of multiple teams or groups, you face separate workspaces for each team and separate logins. That’s a lot of buried messages and missed details. What’s more, anyone who posts a message in Slack channels, resulting in a thread, then gets notifications about replies. And if you’re thinking of turning off notifications, other team members can bypass your Do Not Disturb mode.
- It may not be completely private: While it encrypts messages and data both in transit and at rest, Slack lacks end-to-end encryption. Questions have been raised surrounding Slack’s handling of user data, as well as the threat that the ever-growing number of third-party app integrations pose to the platform and the organizations using it.
Conclusion: Which One Is the Best Slack Alternative for Your Team?
As this list proves, there’s no shortage of different Slack competitors to suit your business. But as needs vary from one team to another, choosing the right solution isn’t easy.
Here are some considerations when choosing a Slack alternative for your team:
- Your specific team communication habits and preferences
- Which features could enhance team performance and which could hinder it
- Your organization’s approach to data privacy and security
If you’re having trouble making up your mind, why not give Brosix a try?
It’s intuitive, secure, and affordable, making this chat tool a solid Slack alternative. It has the right amount of features to ensure teamwork, safeguard communications, and boost your business.e right amount of features to ensure teamwork, safeguard communications, and boost your business.
