20 Best Slack Alternatives for Team Messaging in 2026
We are the team behind Rock, a chat and tasks app for agencies and client teams, so we use and test these tools constantly. Rock is on this list, but this is an honest rundown of the options, not a pitch. We set each one up and used it for real work, so the "best for" and "skip it if" notes come from actually using them.
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.
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

A pricing trend worth watching as you compare. More of these tools now charge for AI as an add-on, on top of the per-user fee. If you already pay for ChatGPT or Claude, that can mean paying twice for the same underlying model. What actually matters is whether the AI is connected to your work, not that the tool has an AI label. Weigh the add-on cost against what it genuinely saves you.

Rock pairs messaging with project boards and notes. One flat price, no per-seat scaling.
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 Slack alternative for combining chat and tasks
Rock is best for agencies and client teams who want messaging plus task and project management in one place, at a flat price instead of per seat. Skip it if you mainly need pure chat, enterprise SSO and compliance, or you already work inside Microsoft or Google.
Rock also connects to AI assistants like Claude and Cursor through a native MCP integration, plus an open API, so you can drive Rock from your AI tools and automate routine work. It is available on the free plan, not gated behind an upgrade.
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
Unlimited: $89/month flat, no per-user fees, unlimited users and spaces
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.
Essentials: $4/user/month
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.
Google Workspace Business Starter: $7/user/month (includes Chat, Gmail, Drive, Meet)
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.
Meet: ~$12/license/month. Suite: ~$22.50/license/month
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.
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.
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+.
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.
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 one your team will actually open every day.
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.
Cloud: ~$4/user/month
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.
Professional: $10/user/month (annual prepaid only)
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.
Enterprise: contact sales (minimum 100 users)
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.
SMB: ~$8/user/month (annual)
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.
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.
Nitro: $9.99/month (individual, mostly cosmetic perks)
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.
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.
Basic: $49/org/month. Standard: $99/org/month
The right workspace should cut how many apps your team switches between, not add to the pile. Fewer tools means fewer missed messages and less context lost.
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.
Premium: $2.50/user/month. Enterprise: $5/user/month
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.
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.
Basic: $29/month for up to 30 users
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.
Unlimited: $6/user/month (full history)
Or skip the per-seat math
Rock combines chat, tasks, and notes. Flat $89/mo for unlimited users.
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.
Which Slack alternative fits you
| If you are... | Best pick | Why |
|---|---|---|
| an agency juggling client chat and tasks | Rock | chat, tasks, and notes in one space, flat pricing |
| already on Microsoft 365 | Microsoft Teams | bundled, deep Office integration |
| on Google Workspace | Google Chat | native to Gmail and Workspace |
| after a free plan with no limits | Pumble | unlimited users and message history free |
| a community or creative team | Discord | always-on voice channels |
| in a regulated or self-hosted setup | Mattermost | open-source, self-hostable |
| a small team on a tight budget | Chanty | free up to 5, cheap paid tiers |
| wanting docs, chat, and meetings free | Lark | full suite at no cost |
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, or the Slack vs ClickUp and Slack vs Discord head-to-heads), 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.
