Team collaboration and business chat software gives teams a shared, real time space to communicate and work together, mainly through messaging. At its core is team chat: organised channels (by team, project or topic), direct messages, and group conversations, where people share updates, files and decisions. Modern platforms add voice and video calls or huddles, file sharing, search across history, and extensive integrations and apps that bring other tools and workflows into the conversation, plus increasingly AI to summarise and assist. Many combine chat with meetings and calling as a broader communication hub. Used by teams and whole organisations, this software is how people communicate and coordinate day to day, especially with remote and hybrid work. The goal is fast, organised team communication and collaboration in one shared space, replacing scattered email and messaging.
It matters because fast, organised communication is how teams coordinate, and email alone is slow and cluttered, while team chat gives real time, searchable, channel based communication that keeps everyone connected and informed, which became essential with remote and hybrid work and now underpins collaboration and culture. As remote work, integrations and AI drive adoption, the category grows. The team collaboration software market reached about 21.5 billion US dollars in 2025 and is forecast to reach 55.0 billion by 2034, a 10.67 percent compound annual growth rate [IMARC Group].
Teams communicate in a shared workspace. Conversations are organised into channels, by team, project, topic or client, which can be public or private, so discussion is structured and searchable rather than lost in inboxes, alongside direct and group messages for one to one and small group chat. People share files, react, mention colleagues, and thread replies to keep topics organised. Most platforms add voice and video calls or quick huddles, screen sharing, and presence. Crucially, integrations and apps connect other tools, project management, code, support, calendars, so notifications and workflows happen in the chat, and bots and AI summarise conversations, answer questions and automate tasks. Search spans the full history, and admin controls, security and compliance govern larger deployments. Some tools unify chat with meetings and phone as a communications hub.
The category spans standalone chat leaders, ecosystem hubs, community and consumer rooted tools, open source and self hosted options, and unified communications. Standalone chat leaders like Slack offer the richest messaging and integration experience. Ecosystem hubs like Microsoft Teams and Google Chat are bundled with Microsoft 365 and Google Workspace and combine chat with meetings and docs. Community and consumer rooted tools like Discord excel at voice and informal, community chat. Open source and self hosted options like Mattermost and Rocket.Chat give control and privacy. Unified communications tools like Webex and RingCentral combine messaging with meetings and phone. The right tool depends on your ecosystem, whether you want standalone chat or a bundled hub, control and privacy needs, and formality.
Chat tools vary by ecosystem, breadth and control, so match to your team.
Standalone chat leaders include Slack. Ecosystem hubs include Microsoft Teams and Google Chat. Community and consumer rooted tools include Discord. Open source and self hosted options include Mattermost and Rocket.Chat. Unified communications tools include Webex and RingCentral, and affordable options include Zoho Cliq.
Start with your ecosystem and what you want. For the richest standalone team messaging and integrations, Slack leads. For the Microsoft ecosystem, Microsoft Teams (often included with Microsoft 365 and combining chat, meetings and calling), and for Google Workspace, Google Chat (bundled and integrated). For community, voice and informal chat, Discord. For open source, self hosted, private messaging, Mattermost or Rocket.Chat. For unified messaging plus meetings and phone, Webex or RingCentral, and for affordable chat, Zoho Cliq. Match the tool to your ecosystem, standalone versus bundled hub, control and privacy needs, and whether you want chat alone or with meetings and phone.
Then weigh three practical factors. First, ecosystem and bundling, Microsoft 365 organisations often use Teams (included), Google Workspace ones Google Chat, which can make chat effectively free, while Slack is the best standalone experience. Second, integrations and experience, Slack leads on integrations and polish, which matters for connecting your tools and adoption. Third, control, security and scope, regulated or technical teams may want self hosted open source (Mattermost), and some want chat combined with meetings and phone (Teams, Webex, RingCentral). Consider pricing (per user, or bundled) and AI features, trial with your team, and cross check verified reviews on G2 and Capterra.
Most team chat is priced per user per month, with free tiers. Slack has a free plan (limited history) and paid Pro from around 8.75 US dollars per user and Business+ around 15. Microsoft Teams has a free plan, paid Essentials from around 4, and is included in Microsoft 365 plans, so many organisations get it bundled. Google Chat is included in Google Workspace (from around 6 per user). Discord is free with optional consumer Nitro. Open source Mattermost and Rocket.Chat are free to self host, with paid tiers (from around 10 and 4 per user). Zoho Cliq is very cheap (from around 1.80), and unified communications tools like RingCentral and Webex cost more (from around 12 to 20) as they include phone and meetings.
The main cost drivers are the number of users and whether chat is bundled with a broader suite. For Microsoft 365 or Google Workspace organisations, Teams or Google Chat may add no extra cost, a big consideration, while Slack is a separate per user cost (though often preferred for experience). Watch free plan limits (Slack limits message history), and whether you need meetings and phone (which raise cost). Self hosting open source trades licence cost for infrastructure. Decide whether chat is bundled or standalone and whether you need unified communications, model cost by users, and use free plans to test adoption before committing.
AI is being woven into team chat, summarising channels and threads, drafting messages, answering questions from conversation history, and powering assistants, reducing information overload. Chat continues as the hub of work, with deeper integrations bringing tools and workflows into the conversation, and chat combining with meetings, calling and docs as unified collaboration. Async and calmer communication is a counter trend, as some teams push back on real time overload (Twist and others). Security, compliance and control drive interest in enterprise features and self hosted open source. And consolidation with the broader productivity suite (Microsoft, Google) shapes adoption.
