20 Best Slack Alternatives for Team Messaging in 2026

Slack handles the messaging part well, but it does not help with tasks, notes, or collaboration with people outside your company. For teams juggling projects, clients, or freelancers, per-user pricing also adds up fast as the group grows.

We put together this list of 20 Slack alternatives with a specific methodology. Every tool here is actually built for team messaging. We verified pricing, checked which tools are still actively maintained, and organized them by category so you can jump to what matters for your team. For each tool, we cover who it is for, what it costs, and when to skip it.

Whether you run a small team, coordinate a distributed group, or collaborate with clients and freelancers, there is something here that fits.

"The function of internal communications has to evolve from broadcasting messages to connecting meaning. Employees don't just want information. They want understanding." - Meghan Keating, VP of Internal Communications, 3M

Find the right Slack Alternative for your team

Answer these 4 questions to get a custom recommendation on a Slack alternative for your team.

Quick Comparison

Tools We Didn't Include (and Why)

This list focuses on tools built for team messaging. That means we left out project management platforms like ClickUp and Basecamp, where chat is a secondary feature rather than the core product. We also removed Workplace by Meta, which shut down in August 2025. Every tool on this list is actively maintained and available to sign up for today.

Best Overall Slack Alternative

1. Rock - Best for Agencies and Client Teams

Picture a 15-person marketing agency running 8 client projects at once. Each project needs its own chat, task board, and file storage. Clients need access without paying for another seat. That is exactly what Rock was built for.

Every project gets a space with messaging, tasks, notes, files, and meetings built in. Clients and freelancers join spaces directly, not through a separate portal or guest account. They see the same chat, the same task board, the same files. No friction.

One thing that sets Rock apart: there is no built-in AI tax. While competitors charge $10-30/user/month extra for AI features, Rock has an open API that lets you connect any AI (ChatGPT, Claude, Gemini) as a bot in your spaces. Bring your own key, pay your own rates, no markup. Your bot can send messages, create tasks, and read everything in a space.

What you get:

• Chat with threads (Topics), audio messages, polls, and scheduled messages
• Task boards with Kanban, list, calendar, and sprint views
• Cross-org collaboration: clients and partners join spaces at no extra cost
• Custom API and bots: plug in any AI or automation you want
• Easy migration from Slack in three steps

Pricing: Free forever (unlimited messages, 5 group spaces) | Unlimited: $89/month flat, no per-user fees, unlimited users and spaces.

Best for: Agencies, studios, and service teams that juggle multiple client projects and want one tool instead of three. The flat pricing means adding your 20th team member costs nothing extra.

Skip this if: You need advanced enterprise features like SSO or compliance certifications out of the box. See the full Rock vs Slack comparison.

Best Enterprise Slack Alternatives

If your company already pays for Microsoft 365 or Google Workspace, you might already have a Slack alternative included in your subscription. These tools are built for scale, not simplicity.

2. Microsoft Teams - Best for Microsoft 365 Users

You know what Teams is. The question is whether it makes sense for your team. If you already pay for Microsoft 365, Teams is included and integrates directly with Word, Excel, SharePoint, and OneDrive. Co-editing a document inside a chat thread is seamless. Video conferencing supports 300 participants on paid plans with Copilot AI for transcription and summaries.

Pricing: Free (100 participants, 60-min meetings, 5 GB storage) | Essentials: $4/user/month.

Best for: Organizations of 50+ people already in the Microsoft ecosystem. If you use SharePoint and Outlook daily, Teams is the path of least resistance.

Skip this if: You are a small team that does not use Microsoft 365. Teams on its own is complex, and the value comes from the ecosystem, not the chat.

3. Google Chat - Best for Google Workspace Users

Same logic as Teams, different ecosystem. Google Chat lives inside Gmail, works alongside Drive, Meet, and Calendar. Conversations happen in Spaces organized by topic. Google's search makes finding old messages fast, and Gemini AI is now built into chats for summaries and suggestions.

Pricing: No standalone free plan. Google Workspace Business Starter: $7/user/month (includes Chat, Gmail, Drive, Meet).

Best for: Teams that run on Gmail and Google Drive. If your team already lives in Google Workspace, Chat is right there.

Skip this if: You want a free standalone messaging tool. Google Chat requires a Workspace subscription, and prices jumped in 2025 when Google bundled Gemini AI into all tiers.

4. Webex (Cisco) - Best for Global Enterprise Teams

Cisco's Webex is the enterprise heavyweight. The standout feature is real-time translation in over 100 languages, which actually works for global teams where English is not the common language. It combines messaging, video, and calling in one platform with certifications that large enterprises require.

Pricing: Free (100 participants, 40-min meetings) | Meet: ~$12/license/month. Suite: ~$22.50/license/month.

Best for: Global companies with teams across language barriers who need enterprise-grade security certifications.

Skip this if: You are a team under 50. Webex is priced and designed for large organizations. The complexity is not worth it for smaller teams.

Best Free Slack Alternatives

Per-user pricing adds up fast. A 20-person team on Slack Pro pays $175/month. These tools give you real team communication features without the bill.

5. Pumble - Best Free Plan Overall

If your only requirement is "Slack but free," Pumble is the answer. Unlimited users, unlimited message history, 10 GB storage, and it looks and feels like Slack. Channels, threads, direct messages, voice and video calls with screen sharing. All free.

Pricing: Free (unlimited users, unlimited history, 10 GB) | Pro: $2.49/user/month for extra storage and features.

Verdict: The most generous free plan on this list. The trade-off is fewer third-party integrations, so if you rely heavily on app connections, check that yours are supported first.

6. Chanty - Best Budget Option for Small Teams

Chanty does one thing well: simple team messaging at a low price. The free plan supports 5 members with unlimited history. The paid plan at $3/user/month is one of the cheapest on this list and includes something unexpected: HIPAA compliance. That makes Chanty one of the few affordable options for healthcare or legal teams.

Pricing: Free (up to 5 members) | Business: $3/user/month with HIPAA compliance.

Verdict: Great if you need an affordable, compliant messaging tool. Less useful if you need a large integration ecosystem or robust task management.

7. Zoho Cliq - Best for Zoho Ecosystem Users

Zoho Cliq only makes sense if you already use Zoho. If you do, it connects directly to Zoho CRM, Projects, and the rest of the suite. The free plan includes unlimited chats and 100 GB of org storage. Volume discounts kick in as your team grows: $3/user at 500 users, dropping to $2/user at 1,000+.

Pricing: Free (unlimited chats, 10K searchable messages) | Standard: ~$3/user/month.

Verdict: A no-brainer if you are in the Zoho ecosystem. Outside of it, there is no compelling reason to choose Cliq over Pumble or Chanty.

8. Flock - Best for Built-In Productivity Tools

Flock bundles to-dos, polls, reminders, and shared notes right into the messaging experience. For small teams that want lightweight task management without adding a separate app, it covers the basics. Admin controls and data retention policies add a layer of security that some free tools lack.

Pricing: Free (up to 20 members, 10 channels) | Pro: $6/user/month.

Verdict: Good if you want built-in productivity features. The jump from free to $6/user is steep compared to Pumble ($2.49) or Chanty ($3), so make sure you need those extras.

"Choosing the right team communication tool is not about finding the most features. It is about finding the tool your team will actually use every day." - Nicolaas Spijker, Marketing Expert

Best Open-Source Slack Alternatives

Open-source sounds great until you realize someone has to maintain the server at 2am. These tools give you full data control and the ability to self-host. They are excellent for dev teams, IT organizations, and regulated industries. But be honest about whether your team has the technical resources to run them. Most agencies and small businesses do not, and that is fine.

9. Rocket.Chat - Best for Self-Hosted Customization

Rocket.Chat is the most customizable option on this list. Host it on your own servers, own all your data, and tailor it to your exact workflow through an extensive API. The community edition is free with no user limit. It also supports federation with Matrix and XMPP, so you can connect with users on other messaging systems.

Pricing: Free (self-hosted, no user limit) | Cloud: ~$4/user/month.

Best for: Development teams or IT departments that want full customization and data ownership. If your team can manage a server, Rocket.Chat gives you more control than any other tool here.

10. Mattermost - Best for Regulated Environments

Mattermost exists for a specific reason: organizations that handle classified or sensitive information. Defense contractors, government agencies, healthcare providers. It supports air-gapped networks, on-premise deployment, and self-sovereign infrastructure. The integrations lean developer-heavy: GitLab, Jira, CI/CD pipelines.

Pricing: Free (self-hosted, up to 50 users) | Professional: $10/user/month (annual prepaid only).

Best for: Teams in defense, government, or critical infrastructure where compliance is not optional. The $10/user price tag reflects the security-first design.

Skip this if: You are not in a regulated industry. At $10/user with annual prepaid, there are better options for general team messaging.

11. Element - Best for Decentralized Communication

Element is the tool governments are choosing. France, Germany, and the UK use it for secure inter-departmental communication. It runs on the open Matrix protocol, which means no vendor lock-in. Your messages are not trapped in one company's servers. End-to-end encryption is on by default.

Pricing: Free (self-hosted community edition) | Enterprise: contact sales (minimum 100 users).

Best for: Organizations that care deeply about data sovereignty and want a messaging standard that does not depend on any single vendor. The government adoption is a strong signal.

Skip this if: You need transparent pricing or a quick setup. Enterprise plans require a sales conversation, and self-hosting requires real technical chops.

Best Secure Slack Alternatives

If your team handles patient data, financial records, or legal documents, "encrypted in transit" is not enough. These tools make security the default, not a paid add-on.

12. Wire - Best for End-to-End Encryption

Wire encrypts everything by default. Messages, calls, files. There is no way to turn it off. The platform is based in Switzerland, which matters because Swiss privacy law is among the strongest in the world. Wire meets compliance standards for finance and healthcare out of the box.

Pricing: Free (personal use, up to 5 users) | SMB: ~$8/user/month (annual).

Best for: Teams in finance, legal, or healthcare that need encryption they can prove in an audit. The Swiss jurisdiction is a real advantage for privacy-conscious organizations.

Skip this if: Budget is a concern. At ~$8/user with a free plan limited to 5 people, Wire is expensive for the core messaging you get.

13. Brosix - Best for Proven Reliability

Brosix has been doing secure team messaging for over 20 years. It is not trendy or well-known, but it works. Peer-to-peer encryption, on-premise deployment, granular admin controls. The flat-rate pricing ($50/month for 20 users) makes budgeting simple for small security-conscious teams.

Pricing: No free plan (14-day trial) | Essentials: $50/month flat for 20 users. Ultimate: $6/user/month (annual).

Verdict: Reliable and boring, in the best way. The interface shows its age, but if you prioritize stability and security over design, Brosix delivers.

Best All-in-One Slack Alternatives

Some teams do not want a messaging tool. They want one app that does messaging plus everything else. These platforms bundle communication with other tools so you work from one place instead of five. The trade-off is complexity. More features means more to learn.

14. Discord - Best for Creative and Community Teams

Let's be honest: Discord is not a business tool. There is no SSO, no compliance, no admin dashboard worth mentioning. But for creative teams, developer communities, and startups that do not need those things, it is hard to beat. Voice channels let people drop in and out of conversations without scheduling anything. The whole platform is free.

Pricing: Free (unlimited messages, voice, video) | Nitro: $9.99/month (individual, mostly cosmetic perks).

Best for: Creative studios, gaming teams, developer communities, and early-stage startups. If your team culture is informal and you do not work with external clients, Discord works.

Skip this if: You need to invite clients into your workspace, need compliance features, or want any kind of task management. Discord has none of that. Rock vs Discord.

15. Lark - Best Feature-Rich Free Plan

Lark (by ByteDance) packs messaging, documents, video meetings, calendars, and AI translation into one app. The free plan supports 50 users with 100 GB of storage. On paper, it is one of the most generous offers on this list.

The catch: there have been reports of free accounts being deleted with as little as 45 days notice. And since ByteDance is a Chinese company, some organizations have data sovereignty concerns. Both worth considering before you go all-in.

Pricing: Free (50 users, 100 GB storage) | Pro: $12/user/month.

Verdict: Incredible feature density for free. But the account deletion reports and data sovereignty questions mean you should think carefully before making Lark your primary workspace.

16. Bitrix24 - Best for CRM and Chat Combined

Bitrix24 tries to be everything: CRM, project management, team chat, video calls, website builder, HR tools. The free plan supports unlimited users. Per-organization pricing ($49/month for the Basic plan) means a 50-person team pays the same as a 10-person team.

The downside is obvious. When a tool tries to do everything, nothing feels polished. Expect a steep learning curve and an interface that can feel overwhelming at first.

Pricing: Free (unlimited users, 5 GB) | Basic: $49/org/month. Standard: $99/org/month.

Best for: Small businesses that want CRM, chat, and project management in one platform without paying per-user. If you are willing to invest time learning the system, the value per dollar is high.

"The right workspace tool should reduce how many apps your team switches between, not add to the list. Fewer tools means fewer missed messages and less context lost." - Nicolaas Spijker, Marketing Expert

Best Niche Slack Alternatives

These tools serve specific audiences that the bigger platforms overlook. If you see your team described below, they are worth a look.

17. Troop Messenger - Best for On-Premise Deployment

Troop Messenger gives you on-premise deployment at a price that undercuts everyone else. At $2.50/user/month for the Premium plan, it is cheaper than most cloud-only tools. End-to-end encryption, LDAP/SSO, and multi-factor authentication come standard. An optional monitoring add-on ($2/user/month) lets admins audit chat history for compliance.

Pricing: No free plan (7-day trial) | Premium: $2.50/user/month. Enterprise: $5/user/month.

Best for: Organizations that need on-premise hosting but cannot justify Mattermost's $10/user price tag. A practical, budget-friendly option for security-conscious teams.

18. Ryver - Best for Chat Plus Task Boards

Ryver combines team chat with built-in task boards and forum-style posts. Flat-rate pricing ($69/month for up to 12 users) makes costs predictable. But there is something you should know: Ryver was acquired by Cloverleaf Networks in 2022. Since then, development has slowed and major updates have been limited. The tool still works, but it is not clear where the roadmap is headed.

Pricing: Limited free version | Starter: $69/month (12 users). Standard: $129/month (30 users).

Verdict: Functional for what it does, but the acquisition and slow updates are a red flag for teams making a long-term bet. You will see Ryver on every alternatives list, but few mention the Cloverleaf acquisition.

19. Connecteam - Best for Frontline and Deskless Workers

Connecteam is not competing with Slack. It is solving a different problem: team communication for people who do not sit at desks. Retail staff, construction crews, field service teams, hospitality workers. The mobile-first app combines chat with scheduling, time tracking, and employee training.

Pricing: Free (up to 10 users) | Basic: $29/month for up to 30 users.

Best for: Businesses with frontline or deskless workers who need more than just messaging. If your team works in the field, Connecteam is built for them.

Skip this if: Your team is office-based. Connecteam's scheduling and time-tracking features are overkill for knowledge workers.

20. Twist - Best for Async-First Communication

Twist (by Doist, makers of Todoist) rejects the entire premise of real-time chat. Everything is organized into threads by topic. There are no "online" indicators, no typing bubbles, no pressure to respond right now. Messages are written to be read later, not in the moment.

This is a strong choice if your team is spread across timezones and you are tired of waking up to 200 unread messages. It forces people to write clearly and think before sending, which leads to better asynchronous work.

Pricing: Free (unlimited users, 1-month message history) | Unlimited: $6/user/month (full history).

Best for: Distributed teams across 3+ timezones who value deep work over instant replies. If your team already practices async and you want a tool designed for it, Twist is the only one that fully commits.

Skip this if: Your team needs real-time coordination. Twist deliberately slows communication down. That is a feature, not a bug, but only if your workflow supports it.

How to Choose the Right Slack Alternative

Forget feature lists for a minute. The right tool depends on three things: how your team works, what you already pay for, and who else needs access.

Start with what you already have. If your company runs Microsoft 365, Teams is included. If you use Google Workspace, Chat is there. Do not pay for a third tool if you have not tried what is already in your subscription.

Think about who needs access. If you regularly collaborate with clients, freelancers, or vendors, you need a tool that makes it easy to invite outside people. Rock handles this with cross-org spaces at no extra cost. Most other tools either charge per guest or make external access clunky. Check our guide on communication strategies for more on managing external teams.

Be honest about self-hosting. Open-source tools like Rocket.Chat, Mattermost, and Element are powerful. But they require dedicated IT resources. If your team does not have someone who can manage a server, stick with a cloud-hosted option.

Match the tool to the problem. Need security? Wire or Mattermost. Need free? Pumble. Need chat plus tasks for client work? Rock. Need async? Twist. Do not pick the tool with the most features. Pick the one that solves your actual problem.

Final Thoughts

Slack is a good tool. It is also expensive, noisy, and missing built-in task management. That is why this list exists. Not because Slack is bad (see our honest Slack review), but because different teams have different needs.

We covered 20 alternatives across six categories. Some are free, some are enterprise-grade, some are niche. If your team is coming from a consumer app like Facebook Messenger, Telegram, or WhatsApp (see our Slack vs WhatsApp head-to-head), those guides cover the upgrade path in more depth. The best one is the one your team actually uses. Pick one, try the free plan, test it on a real project. You will know within a week if it works.
