Microsoft Teams Alternatives

Best for: Chat-first team collaboration with channels and integrations.

Slack is a workplace messaging platform centered on channels, direct messages, huddles, file sharing, workflow automation, and a large app marketplace. It is a strong Teams comparison point for organizations that want chat-first collaboration and many third-party integrations rather than a Microsoft 365-centered workspace.

Pricing: Free and paid plans are listed on Slack’s pricing page; check current limits and AI features before choosing.

Best for: Matrix-based secure messaging with hosted and self-hosted options.

Riot.im is now known as Element, a Matrix-based secure messaging and collaboration app. It is most relevant for teams that care about end-to-end encryption, interoperability, federation, and self-hosting options rather than a conventional SaaS-only collaboration suite.

Pricing: Element offers free/community options and commercial plans; verify deployment and support requirements on Element’s pricing page.

Best for: Secure team messaging, calling, conferencing, and file sharing.

Wire is a secure messaging and collaboration platform with end-to-end encrypted messaging, calls, conferencing, and file sharing. It is a closer fit for privacy-conscious teams and regulated organizations than for teams that mainly want Microsoft Office-style document collaboration.

Pricing: Wire lists a free tier and paid SMB or enterprise options; confirm current limits and billing terms on its pricing page.

Best for: Self-hosted or private team collaboration for technical teams.

Mattermost is a collaboration platform often chosen by technical, DevOps, security-sensitive, and regulated teams that want private or self-hosted deployment. It supports channel-based messaging, integrations, calls, screen sharing, and enterprise controls, but it requires more operational planning than a turnkey SaaS chat tool.

Pricing: Mattermost publishes commercial plans and a free open-source Team Edition; verify support and hosting costs.

Best for: Historical secure group messaging product; manual review needed.

Semaphor was SpiderOak’s secure team messaging and file-sharing product. Current public signals are weak: the main SpiderOak business has shifted toward other security products, and recent Semaphor release information is old. Treat this entry as historical until an active official product page is verified.

Pricing: Current pricing could not be confidently verified from an active official product page.

Best for: Simple team chat with tasks, calls, and file sharing.

Chanty is a team communication app for small and mid-sized teams that want messaging, audio and video calls, tasks, file sharing, threads, voice messages, and a simpler workspace than larger enterprise platforms. It is a practical Teams alternative for lightweight collaboration rather than complex Microsoft 365 administration.

Pricing: Chanty lists free and business plans; verify current per-user pricing and on-premises terms.

Best for: Historical community chat/forum project; not a current Teams replacement.

Spectrum was an open-source community conversation platform that combined forum-style threads with real-time chat. It was acquired by GitHub, and there is no clear active official SaaS product to recommend today. This entry should be reviewed as historical rather than presented as a live Teams replacement.

Pricing: No current official pricing was found for an active hosted Spectrum product.

Best for: Browser-based video meetings; official status unclear.

VideoMeeting appears to refer to a browser-based WebRTC video conference project from RedcoolMedia rather than a full workplace collaboration suite. Because a current official product page and support path were not clearly verified, it should be reviewed before being kept as a Microsoft Teams alternative.

Pricing: Current pricing and maintenance status could not be verified from an official source.

Best for: Lightweight third-party desktop client for Slack and Discord.

Ripcord is a compact third-party desktop client for Slack and Discord, not a standalone team collaboration platform. It may appeal to power users who want a lighter desktop interface, but it should not be treated as a direct Microsoft Teams alternative for organizations evaluating official workplace communication tools.

Pricing: Ripcord is distributed as shareware; verify current license and platform support on the official site.

Best for: Old Slack theme project, not a collaboration platform.

Sblack appears to refer to a Slack black/dark theme project rather than a team communication product. Since Slack now has official appearance options and the theme repository is old, this entry is not a meaningful Microsoft Teams alternative and should be removed or archived after review.

Pricing: No pricing applies; this is a theme/customization project, not a SaaS product.

Best for: Discontinued Atlassian team chat product.

Stride was Atlassian’s team chat product, but it was discontinued years ago after Atlassian moved customers toward Slack. It should not be listed as a live Microsoft Teams alternative except in a historical note or migration article.

Pricing: No current pricing applies because the product is discontinued.

Best for: Closed enterprise social collaboration platform.

Workplace from Meta was an enterprise communication platform for company updates, groups, and employee communities. Meta has closed Workplace, so it should not be presented as a current Teams alternative. Existing users needed migration planning rather than a new signup path.

Pricing: No current signup pricing applies because Workplace has closed.

Best for: Unverified collaboration app listing; manual review needed.

Zala could not be confidently matched to an active official team collaboration product. Some older directory references describe a chat, checklist, and file-sharing app, but an official current website, pricing page, and supported platforms were not verified. This entry should be reviewed before publication.

Pricing: Current pricing could not be verified.

Best for: Unmaintained open-source Slack desktop client.

Wey is an open-source Slack desktop client built with Node.js and Yue, not a Microsoft Teams replacement. Its repository explicitly says the project is not actively maintained and warns users not to use it for work because messages may be missed. It should be removed from a serious Teams alternatives list.

Pricing: No commercial pricing found; the project is open source but not actively maintained.

Best for: Workplace collaboration app with unclear current status.

Crugo was described as a workplace collaboration platform for messaging, files, tasks, calendars, and team organization. The official site was not confidently verified as active during this review, so this item should be manually checked before being kept as a current Microsoft Teams alternative.

Pricing: Current official pricing could not be verified.

Best for: Video-first collaboration with meetings, chat, phone, and whiteboard.

Zoom Workplace combines meetings, team chat, phone, whiteboard, clips, scheduler, mail, calendar, and AI-assisted productivity features. It is a relevant Teams alternative for organizations that prioritize video meetings and want chat and collaboration tools around a strong meeting experience.

Pricing: Zoom publishes free and paid Workplace plans; verify meeting limits, AI features, and regional pricing.

Best for: Google Workspace-native messaging and spaces.

Google Chat is Google Workspace’s team messaging product, with spaces, direct messages, files, huddles, and tight links to Gmail, Calendar, Drive, Meet, and Groups. It is a natural Microsoft Teams alternative for organizations already standardized on Google Workspace.

Pricing: Included with Google Workspace at no additional cost; premium features depend on Workspace plan.

Best for: Enterprise meetings, messaging, calling, and webinars.

Cisco Webex is a business collaboration suite covering meetings, messaging, calling, webinars, events, whiteboarding, polling, and video messaging. It is especially relevant for companies that need enterprise meeting controls, calling options, and Cisco-oriented communications infrastructure.

Pricing: Webex offers free and paid plans; check host licensing, calling, webinar, and add-on costs.

Best for: Open-source secure messaging with self-hosted and enterprise options.

Rocket.Chat is an open-source communications platform for secure messaging, voice, video, apps, and internal or external stakeholder communication. It is most relevant when organizations want self-hosting, dedicated hosting, data control, or private deployment rather than a fully Microsoft-managed service.

Pricing: Rocket.Chat offers free entry points and commercial plans; verify deployment, support, and hosting costs.

Best for: Self-hosted chat and video meetings inside Nextcloud Hub.

Nextcloud Talk adds chat, audio/video conferencing, screen sharing, webinars, and private collaboration to the Nextcloud ecosystem. It is a practical Teams alternative for organizations that already use Nextcloud or want open-source, self-hosted communication with file collaboration nearby.

Pricing: Community use is open source; enterprise pricing depends on Nextcloud support plans and user counts.

Best for: Open-source topic-threaded team chat for async collaboration.

Zulip is an open-source team chat app built around topic-based threading, which makes it useful for remote teams, developer communities, and groups that need organized async conversations. It can be used as a hosted cloud service or self-hosted for more data control.

Pricing: Zulip has a free cloud plan, paid cloud plans, and self-hosted options; verify history and storage limits.

Best for: Team chat, channels, meetings, and Zoho workflow integration.

Zoho Cliq is a team communication app with chats, channels, meetings, workflow features, and Zoho ecosystem integrations. It is relevant for small and mid-sized businesses that use Zoho apps or want a lower-complexity collaboration tool with web, desktop, and mobile availability.

Pricing: Zoho Cliq has free and paid plans; verify feature limits and bundle availability with Zoho Workplace.

Best for: Team messaging with channels, threads, and meetings.

Pumble is a business communication and team messaging tool with channels, direct messages, threads, file sharing, meetings, and a generous free positioning. It is a useful comparison option for small teams that want a Slack-like workspace without immediately adopting Microsoft 365 or Google Workspace.

Pricing: Pumble lists a free plan and paid per-seat upgrades; verify current limits, storage, and integrations.
