Collaboration apps are a dime a dozen. Probably not the right choice of words, but there are so many that it’s hard to choose the right one for your business. And when you’re a small business that runs a tight ship, you want to find the best collaboration app for your team and pay as little as possible, right?

Luckily, some of the most popular team collaboration tools in the market offer a free plan, and we did some digging to find ones that give you the most bang for no bucks at all! 

Here are the 7 best free collaboration apps for your small business.

1. Flock

With Flock, team members can exchange messages, share files, host video conferences, manage to-dos, and set up calendar events all from one easy-to-use app. Flock integrates with popular business tools such as Google Calendar, Google Drive, Asana, MailChimp, and Twitter, making it easier for team members to stay on top of things without juggling a dozen different apps. 


Flock’s free plan gives your team:

  • Unlimited team members and one-to-one messages
  • 10 public channels for group conversations
  • Unlimited 1:1 video calls
  • 5GB storage for file sharing and 10K message history for quick search
  • Built-in productivity apps such as shared notes, polls, and reminders 
  • Unlimited integrations for third-party services, such as Asana, Jira, or Google Drive

Need more room? Flock PRO unlocks enhanced admin controls, group video conferencing, unlimited channels, guest accounts, more file storage, and access to priority support. At just $4.50 per user per month, we think it’s a steal, but our free plan is pretty generous and well, free. It’s your call.

2. Slack

If you’ve heard of team chat, you’ve probably heard of them. IM, channels, video calls, integrations and bots for hundreds of third-party tools; Slack has it all. But the free plan limits you to 10 service integrations, so choose wisely.

Slack’s free plan

  • Unlimited users, messages, and channels
  • Unlimited one-to-one voice and video calls 
  • 5GB storage for file sharing and 10K message history
  • Up to 10 apps or service integrations

For video conferencing (up to 15 participants) and guest accounts, you’ll need to upgrade to a Standard plan that costs $6.67 per user per month. There’s also a Plus plan that adds more features at $12.50 a user per month. 

3. Microsoft Teams

Initially an exclusive for businesses with Office 365 subscriptions, Microsoft Teams has since launched a free plan for small businesses. We love its innovative features such as inline translation for messages and the ability to record meetings with automatic transcriptions. Also a plus, its deep integrations with OneDrive and Office 365 services.

Microsoft Team’s free plan

  • Up to 300 users
  • Unlimited messages, channels, and search
  • Unlimited audio and video meetings with up to 250 participants
  • 10GB of team file storage + 2GB per user
  • 140+ apps and service integrations

For advanced collaboration features such as meeting recordings and automatic transcriptions, you’ll need to pony up for an Office 365 subscription.  Office 365 Business Essentials costs $5 a user per month and the full-featured Office 365 Business Premium will set you back $12.50 a user per month.

4. Twist

Made by the folks behind Todoist, Twist makes it easy to organize and keep track of discussions with threads. Their message board-like interface is easy to use, though using threads and the inbox (they work more like email threads, not Slack threads) takes some getting used to. The upside? Fewer notifications!

Twist’s free plan

  • Unlimited users, guests, messages, channels, and threads
  • Access to 1 month of conversations
  • 5GB storage for file sharing
  • 5 service integrations

Twist doesn’t bother with audio/video conferencing or screen sharing features, they have a Wherein integration instead. For $5 a user per month, Twist Unlimited offers unlimited conversation history, file storage, service integrations, and priority support.

5. Discord

Discord bills itself as an all-in-one voice and text chat for gamers, and it’s clear why. In addition to the usual private and group DMs, Discord offers a new way of collaborating in real-time: Voice channels. Think of them as always-on radio channels to talk to your team. Loved by gamers, voice channels can also be an easier, less stressful way to collaborate remotely on shared documents. More importantly, Discord offers unlimited voice, video, and text chat—all for free!

Discord’s free plan

  • Unlimited users, messages, text and voice channels, and file sharing (individual file size < 8MB)
  • Unlimited video conferences with up to 10 participants + screen sharing
  • A cool Text-to-Speech function that reads out what you type!

Discord Nitro Classic lets you upload a GIF avatar, use custom emojis everywhere, and ups that pesky file size limit to 50MB - for $4.99 per user per month. 

6. Zoho Cliq

Zoho Cliq lets you view multiple conversations—each in its own column—so you don’t have to shuffle back and forth between a channel discussion and a private chat with a colleague. Also, host video conferences with up to 100 participants on the free plan. 

Unsurprisingly, Cliq integrates smoothly with other Zoho apps, but there are also integrations for third-party services such as Asana, Wrike, and Zapier.

Cliq’s free plan

  • Unlimited users, messages, and channels (up to 100 members in each)
  • Video conferencing with up to 100 participants + screen sharing
  • 100GB storage for file sharing and 10K message history
  • 10 third-party app integrations

For $3 a user per month, Cliq Unlimited offers unlimited message search, ups file storage, and lets you connect up to 100 third-party integrations. It also unlocks the PrimeTime Assembly feature, so you can stream live video to as many as 10,000 participants.

7. Rocket.Chat

If on-premise software is a must, look no further than Rocket.Chat’s open-source team collaboration app. Easily deployed to on-premise or cloud servers, Rocket.Chat is free with zero restrictions on core functionality. It’s your server! Just one caveat: If there’s trouble, you’re probably on your own - the free plan doesn’t come with any web, email, or phone support, so be prepared to hunt through pages of technical documentation for any fixes.

  • It’s open-source, customizable, and you own all your data (again, it’s your server)!
  • Inline message translations
