The modern age and various unprecedented circumstances have pushed a large part of the global workforce to go mobile and/or start working from home. This transition has led to a rise in tools that allow these workers to accomplish their work tasks and remain in constant contact with their management, colleagues, and clients. Among the most popular ones have been online collaboration tools.

Not only have these tools helped facilitate normal communication among employees, but many of them have also provided handy collaboration options to better organise individual and group tasks, distribute them among individuals, keep track of their progress, and streamline the entire work process.

Without further ado, here are the best tools we discovered while scouring the online collaboration market.

The best online collaboration tools available

1. Microsoft 365

  • Robust and user-friendly apps
  • Bundles for any user
  • Microsoft Teams with UC


  • Somewhat limited collab features

Microsoft’s collection of cloud-based office tools, known as Microsoft 365 (formerly known as Office 365), is one of the most popular platforms of its kind, for more reasons than one. All the tools are easy to use, capable, and, most importantly - allow teams to collaborate in real-time on documents, from texts to spreadsheets to presentations, and more.

The appeal of Microsoft 365 is also in its accessibility on all major operating systems, including Windows, Mac, iOS, and Android. Some Microsoft 365 packages include Microsoft Teams, facilitating the integration of unified communications with the common office software.

Microsoft 365’s prices depend on whether you’re a personal or business user. The former starts at £5.99 a month, while the latter begins with Business Basic at £4.50 per user a month. From there, it gets somewhat more expensive with Apps for Business at £7.90 per user a month, Business Standard at £9.40 per user a month, and Business Premium at £16.60 per user a month. All of these prices are based on annual subscriptions, with Business Basic the more more economical option. While this option doesn’t include desktop versions of Office apps, it does include Exchange, OneDrive, SharePoint, and Teams services.

2. Slack

Handy collaboration tool that won’t eat up your resources

  • Excellent service for free
  • User-friendly and intuitive interface
  • Isn’t heavy on resources


  • Free version only retains 10,000 messages

Slack is a popular collaboration tool that can be used on both desktop and mobile devices. Its primary function is exchanging direct messages and files between persons or inside a user group, expanded by the capability to organise chats into channels, say, for a specific project, department, company, topic, etc.

This tool stands out from the crowd thanks to its support for voice and video calling, be it through its desktop or mobile app, allowing for more direct contact when needed. There’s even your space inside the app, where you can draft messages, list your to-dos, or keep links.

This is in no way typical cloud storage but is very useful for sharing files with your colleagues (or keeping them on hand for yourself). While it lacks the cloud storage functionality, Slack can integrate with the likes of Google Drive, Box, Microsoft 365, and Dropbox. The best part? You won’t even notice it’s there if you’re not actively using it, as it doesn’t use up too much of your device’s resources.

You can use this awesome app for free with some limitations, such as the number of stored messages (up to 10,000), storage space, and so on, but no limitations on the length of time used. There are three paid plans - Pro at £5.25 a month, Business+ at £9.75 a month, and Enterprise Grid with customised pricing for extra-large businesses.

3. Asana

Proven track record in the industry

  • Limited communication options

Asana is a well-known player in the collaboration field that has been offering its services for quite some time to the likes of Intel, Pinterest, TED, and Uber.

Asana also has an integration with Microsoft Teams, Jira Server, and Zoom.

All the projects can be planned, visualised, and organised in a list, board, or calendar format, while a search option allows you to swiftly find any past task. You can get your hands on the Basic Asana package for free, with the only limitations on the file (100MB) and team size (15 members).

Paid plans include Premium at £9.49 per user a month (annual subscription), Business at £20.99 per user a month (billed annually), or a custom-priced Enterprise package. The Premium plan adds a timeline view, advanced search and reporting, forms, rules, milestones, and an admin console.

You can pick whether you want to be billed monthly or annually, with the latter option entailing some discounts. If you have up to five employees, you qualify for a rather limited yet free service that provides task management, apps, and workspaces.

At £9.33 per user a month, Plus will get you a light user role, automated workflows, and read-only access.

  • Beginner-friendly
  • Handy extras


  • Some glitches in the app

Ryver focuses primarily on providing your business with an effective way of communication, accompanied by some surprising bonuses. One of them are filters for who can see your posts in the app and join your teams. You can also save your company’s posts in the Facebook-like newsfeed, for accessing them later.

The platform is available across all major operating systems (including Mac and Linux) and allows you to create countless teams inside those apps, categorise them, and set up chats with individuals or groups.

If you have up to 12 users, Ryver can be yours for just £57.45 a month (Starter), providing you with unlimited chat and file-sharing, task management, as well as video and voice calls. Increasing the number of users to 30 on Standard also increases the price to £107.40 a month, but also adds custom invite links. There's also a Medium Pack plan for over 30 user, offering the same functions and tools but for £3.89 per user a month. Finally, the Enterprise account, available via contacting sales, offers single sign-on (SSO), a testing sandbox, advanced team management, and premium support.

Trello is another popular collaboration and project management platform that can be installed on both desktop and mobile.
