Best Slack Alternatives


Online communication tools have become a lifeline in the last couple of years. Whether it was digital transformation, more flexible working, or the mandated ‘rest in place’ regulations of the global pandemic, business teams have become accustomed to using online chat tools as a virtual alternative to the physical workspace. 

In fact, tools such as Slack have become an indispensable asset for businesses. Without being able to conduct physical meetings, catch-ups and scrums, teammates have turned to online collaboration tools for basic communications purposes, and as a result, use of these tools is set to only increase. 

With over 10 million active daily users, Slack has become an integral daily tool in the tech stack for many businesses. Said to boost productivity, simplify workflows, it has become a hugely popular tool, and a go-to option for team collaborations. 

While slack offers a cost effective, reliable platform for online team chat, not all users have been satisfied with the functionality of the platform. As remote and hybrid teams become increasingly commonplace, finding a comprehensive, easy to use platform with a holistic range of features has become more important for many. 

What’s more, as Slack went public, and shifted to focus more on the enterprise market, smaller teams, start-ups or those with more unique communications needs have been on the lookout for an alternative platform. 

Whether you want a comprehensive communications tool to bring together all your essential third-party apps, or you simply want to share gifs and emojis with your colleagues, for those looking to branch out and explore some of the alternative options, we’ve put together a list of 11 of the best Slack alternatives on the market.

Why Seek Slack Alternatives? 

While Slack might be great for online team collaboration, themed threads and direct and group messaging, it may fall short in some areas. For some businesses, for example, if your organisation requires reliable and secure VoIP services, project management capabilities, file sharing and storage as well as the core team chat functionality, shopping around for an all-in-one, unified platform might be a more cost-effective option. 

One sticking point for Slack users is that teams would prefer not to pay a premium for unlimited search functionality, which is currently limited to the most recent 10,000 messages.  Likewise, for many dynamic teams and start-ups, team leaders might want a self-hosted platform, and you may wish to ensure your essential chat app tool integrates with any other essential solutions you use on a daily basis. Integrations with all your essential day-to-day tools can significantly improve your team productivity, streamline workflows and drive better cost-efficiency. For this reason, many unified, open-source platforms such as RingCentral offer off-the-shelf integrations with popular applications such as Dropbox, Calendars, Social Media platforms or your Salesforce CRM and give teams the chance to customise their virtual workspace hub with custom integrations. 

Whether you’re looking for a cost-effective enterprise tool such as Microsoft Teams, Google workspace, or you’re keen to find a start-up-friendly alternative that focuses on integrations and efficiency, our ultimate list of the best Slack alternatives should shine a light on some of the best options. 

Factors to Consider for a Slack Alternative

Selecting the best option to address your organisational goals, as well as meeting the needs of your teams, requires a little research. Be prepared to shop around for the right solution, and where possible, look for solutions that offer a free version of the app or solution so that you and your users can try before you buy. 

The right collaboration platform can make or break your team efficiency, not to mention underpin your company culture in a virtual capacity. It’s super important to take into account the features you’ll need when it comes to scalability, work-life balance and effective project management.  

It’s worth taking the following factors into consideration before making the investment in a new platform: 

  • Your security and data compliance needs
  • Budget per user
  • VoIP resilience and business continuity 
  • Video quality and conferencing needs (internal and external meetings)
  • Whether you’ll need a hosted or self-hosted platform
  • File sharing and file collaboration 
  • Team workflows and optimising efficiency 

It’s worth noting the difference between hosted, open-source, or self-hosted platforms here. A hosted platform will mean you simply log in and use the platform, the software itself is managed and maintained by the app creators. Slack is a good example of a hosted platform. 

If you’re looking to veer away from Slack, it might be worth reviewing whether you might be better off with an open source or self-hosted application in its place.  

If you want better security and control over your own data, it’s worth looking for a self-hosted (or on premises) collaboration system. That way, you can retain full control and administrative authority over the server. 

An open-source platform will mean that the code is publicly available for users to modify or customise their own platform as required. With an open-source, or open api platform, such as RingCentral, you have the flexibility and freedom to make your unified solution completely bespoke to you; personalised for the needs of your organisation, your teams, and individual users.

The verdict on RingCentral and Slack

When it comes to choosing a collaboration platform, it’s important to understand what your business teams might need, and what you need to meet your organisational objectives. 

Do you have plans to grow the business in the next few years? Will you be taking on new business in international territories? Do you need to think about your data security and safeguarding your business privacy above all else? Whatever your unique business needs are, you’ll need to ensure you invest in the right platform for you, before implementing a new solution, deploying the technology and training your staff how to use it.

It’s also important to consider the impact a unified platform could have on your workers, and how much more productive your team members could be with the right all-in-one solution. At a time when app overload is becoming a very real productivity killer, and workers waste around 32 days per year simply toggling between platforms, finding a platform that offers all of your essential collaboration capabilities in one platform could be a make or break for your more productive teamwork.  

With a unified platform such as RingCentral, businesses can benefit from essential phone, messaging, video calling capabilities, and share files. In addition to this, key an all-in-one platform such as RingCentral offers collaborative features such as screen sharing, file sharing and storage, calendar integration, advanced phone features such as call routing call queuing and auto attendants as well as call and video meeting recordings.  

While Slack has become a go-to platform for real-time chat, the features it offers can fall short for businesses looking for a more all-encompassing approach to their communications. For example, while Slack does offer video calling, users are limited to one-to-one calls unless they upgrade to a paid plan. Likewise, features such as screen sharing are reserved for those on a paid plan and the quality and sophistication of Slack’s video offering has come under fire, so many businesses using Slack turn to an additional solution for video calling, reducing the ability to streamline their communications channels. In terms of file storage, freemium Slack users will be limited to 5GB of storage, where RingCentral offers unlimited space. 

What’s more, RingCentral’s open api platform means you can integrate with hundreds of off-the-shelf tools, but also tailor your platform to sync with more bespoke or niche platforms specific to the needs of each team. 

For those looking for a platform that allows you to collaborate easily with an unlimited number of external users, RingCentral’s easy-to-use platform also offers unlimited users and guest users so you can chat with colleagues, customers, and external stakeholders from anywhere at any time.
