Let me tell you about a conversation I had last week with a friend who runs a small non-profit. "We’re spending more on Slack than on some of our programs", she said, visibly frustrated. And honestly, I get it. Tools like Slack are great, but when you're trying to keep costs low and still manage effective communication, those subscription fees can feel like a punch in the gut. At $8.75 per user per month for Slack’s Pro plan - and an extra $10 for AI features - it’s easy to see how quickly the costs add up, especially for small teams or organizations with tight budgets.

Here’s the thing: remote work isn’t slowing down. By 2025, 22% of the American workforce is expected to be working remotely. And poor communication? It’s costing businesses more than $1,000 per employee every month. That’s why we’ve put together this guide on affordable Slack alternatives. Whether you’re a startup, a non-profit, or a remote team, there are budget-friendly options out there that don’t skimp on features.

In this article, I’ll walk you through some of the best alternatives, including Pebb, which offers a free plan for teams of up to 1,000 users, and other options like Microsoft Teams, Google Chat, Discord, and more. We’ll cover pricing, features, and who each platform is best for, so you can find the perfect fit for your team without blowing your budget.

5 Top Alternatives to Slack for Team Communication & Collaboration

1. Pebb

At Pebb, we set out to solve a problem that so many startups, non-profits, and remote teams face: tight budgets paired with the need for reliable communication tools. We knew there had to be a smarter, more affordable way to provide everything teams need without the massive price tag that often comes with enterprise solutions.

Pricing That Works for Real Teams

Let me cut to the chase: Pebb is free for teams of up to 1,000 users. Yes, free. No hidden fees, no gimmicks. And if your organization needs more advanced features, our premium plan is just $4 per user per month - a price point that’s hard to beat for a platform offering this much.

Here’s the best part: our free Standard plan isn’t some watered-down version. It includes work chat with unlimited message history, a live news feed, a knowledge library, task management, calendar integration, and unlimited clubs. The only things missing are a few admin controls and advanced analytics. Essentially, you’re getting a complete communication suite without breaking the bank.

Built for Real-World Collaboration

We designed Pebb to be an all-in-one solution because, let’s face it, juggling multiple apps can be a productivity killer. Here’s what you’ll find:

• Work Chat: From private one-on-one messages to department-wide discussions, we’ve got you covered.

• News Feed: Keep everyone in the loop with company announcements and updates.

• Knowledge Library: A centralized hub for storing and accessing critical documents and resources.

For teams that need a little extra, our premium plan takes things up a notch with features like advanced analytics to track engagement, unlimited admin permissions, voice and video calling, and seamless integrations with tools like Google Drive and HRIS systems.

Who's Pebb Perfect For?

We’ve seen Pebb thrive in all kinds of environments, but it’s especially a game-changer for:

• Remote-first startups: Stay connected and productive without draining your budget.

• Non-profits: Use our free plan to keep your resources focused on your mission.

• Distributed teams: Whether your team is spread across time zones or working from coffee shops, Pebb ensures everyone stays in sync.

Seamless Integration for Better Workflows

We’re all about making life easier, and that’s why we focus on integrations that matter. With our Google Drive integration, you can share and collaborate on documents without ever leaving Pebb. And our HRIS integration? It simplifies employee onboarding and directory management.

The real magic lies in how Pebb cuts down on app-switching. Instead of bouncing between tools for chat, files, and employee info, everything you need is in one place. It’s your central hub, designed to keep your team connected and productive - without wasting time or money.

If you’re looking for a solution that’s easy on the budget but packed with features, Pebb might just be the answer you didn’t know you needed.

2. Microsoft Teams

At Pebb, we pride ourselves on offering a free, all-in-one solution, but let’s be honest - Microsoft Teams has carved out a serious name for itself in team communication. With over 320 million daily users in 2023, it’s a heavyweight in the collaboration space. Here’s how it stacks up, especially if you’re keeping an eye on costs.

Pricing That Grows With You

Microsoft Teams uses a tiered pricing system that caters to teams of all sizes. It starts with a free version, which includes group calls, unlimited chat, and 5 GB of cloud storage. If you need more, you can step up to Microsoft Teams Essentials for $4.00 per user per month (billed annually) or $4.80 per user monthly. For those needing more robust options, there’s Business Basic at $6.00 per user per month (annual billing) and Business Standard at $12.50 per user per month. One thing to note - Microsoft recently added a 5% premium for monthly billing on annual plans, so committing to a yearly subscription could save you some cash.

Collaboration Features That Deliver

Teams brings everything together in one place - chat, video calls, file storage, and app integrations. Its real-time collaboration tools make it easy to share and edit documents with your team. Plus, the channel system keeps conversations neat and tidy, whether you’re organizing by department, project, or client. These features are the backbone of Teams and set the stage for its impressive app integration capabilities.

Who Should Consider Teams?

If your team is already using Microsoft tools like Word, Excel, or SharePoint, Teams is a natural fit. The integration is seamless and makes life easier for organizations already tied into the Microsoft ecosystem. Here’s where Teams really shines:

• Small businesses that need straightforward collaboration tools without extra frills.

• Remote teams that rely on dependable video calls and file sharing.

• Companies looking to simplify by replacing multiple tools with one unified platform.

Forrester analyst Amy Chang highlighted a key benefit: businesses can save up to $9,000 annually per 100 users by consolidating tools like Zoom, Asana, and Dropbox into Teams. That’s a solid reason to consider it.

Integration That Goes the Extra Mile

One of Teams’ standout strengths is its ability to integrate with over 2,500 apps. Naturally, its best integrations are within the Microsoft 365 suite - think Planner for managing projects or Power BI for analytics. But it doesn’t stop there. Teams connects with Zapier, opening the door to thousands of other apps, and it supports third-party telephony providers and contact center solutions, making it flexible for companies with existing phone systems.

And here’s a cool feature for frontline workers: the built-in walkie-talkie tool. Walmart rolled it out and saw a 28% improvement in shift coordination by 2024. It’s little things like this that make Teams a versatile choice for a variety of industries.

3. Google Chat

Google Chat is seamlessly integrated into Google Workspace, making it a natural choice for teams already using Google's suite of tools. With an impressive 3 billion users relying on Google Workspace to collaborate and stay connected, it's clear that Google has built something that resonates with a massive audience.

Budget-Friendly Pricing Options

One of the standout perks of Google Chat? It comes bundled with Google Workspace at no extra cost. That means you're not shelling out additional money for chat features - it’s all part of the package. Here’s a quick breakdown of Google Workspace pricing:

• Business Starter: $6.00 per user/month, includes 30 GB of pooled storage.

• Business Standard: $12.00 per user/month, offers 2 TB per user.

• Business Plus: $18.00 per user/month, with even more advanced features.

Nonprofits get an even sweeter deal. With an annual commitment, pricing starts as low as $3.50 per user/month, and eligible organizations can even access the full Workspace suite entirely free through Google's nonprofit program.

Tools That Simplify Collaboration

Google Chat keeps things straightforward with features like direct messaging, Spaces for group collaboration, and AI-powered tools like smart compose, autocorrect, and conversation summarization. The new Gemini integration takes it up a notch by answering questions, summarizing long conversations, finding files in Google Drive, and even helping with brainstorming sessions.

Here’s what users love: 96% praise the instant communication features, especially the ability to check availability and send quick messages. Another 93% highlight how well it integrates with Google Calendar and Meet, making scheduling and coordinating meetings a breeze. For teams that prioritize ease and speed, this setup is a win.

Who Should Consider Google Chat?

Google Chat shines for teams already immersed in the Google ecosystem. Nonprofits and educational groups, in particular, will appreciate the affordable pricing and intuitive interface. Remote teams craving dependable, straightforward communication tools and small businesses looking to streamline their software stack will also find it appealing. A 2025 study revealed that 90% of businesses using Google Workspace tools reported noticeable improvements in teamwork and productivity.

Easy Integration for Maximum Efficiency

Google Chat’s tight integration with Gmail, Calendar, Drive, Meet, and other core Google apps ensures a smooth workflow. It also supports third-party tools like Zapier, PagerDuty, Workday, and Trello. The Google Workspace Marketplace offers even more productivity tools that can be directly linked to your conversations. Plus, IT teams will appreciate the Single Sign-On (SSO) functionality, which works with over 200 cloud apps using SAML for simplified access management.

If you're transitioning from platforms like Slack or Microsoft Teams, Google has you covered. Chat APIs and partnerships with CloudFuze and CloudM make it easier to migrate your existing data. While Google Chat thrives as part of the broader Google Workspace ecosystem, Pebb offers a standalone solution with a free plan for up to 1,000 users and premium features priced at just $4 per user/month.

4. Discord

When you think of workplace communication, Discord might not be the first tool that comes to mind. But let me tell you, this platform - originally built for gamers - has carved out a niche for startups, non-profits, and remote teams looking for a more community-driven approach. It’s affordable, informal, and surprisingly versatile.

Free-First Pricing That Packs a Punch

Discord’s pricing is refreshingly simple. The free version gives you access to all the essential features without any user limits. If you’re looking for a little extra, there’s Nitro Basic at $2.99 per user monthly (or $29.99 annually) and the full Nitro plan at $9.99 per user monthly (or $99.99 annually).

Nitro Basic upgrades your experience with perks like 50 MB file uploads, custom emoji usage across servers, and even personalized video backgrounds. The full Nitro plan takes it further, offering 500 MB file uploads, HD video streaming, and two free server boosts. However, if you’re running a larger team and want everyone on Nitro, those costs can add up fast.

Collaboration That Feels Like a Community

Discord shines when it comes to organizing conversations. You can set up categories and channels to match your team’s structure or specific projects, keeping everything clean and organized. It’s got all the essentials - real-time chat, screen sharing, and even bots to automate repetitive tasks. Plus, security features like two-factor authentication and role-based access control ensure your communications stay safe.

One feature I love is the ability to pin important messages in each channel. It’s perfect for keeping shared docs, meeting notes, or task lists front and center. For example, WP Mail SMTP uses Discord alerts to flag issues with their contact forms in a dedicated "Website Notifications" channel. It’s a simple but effective way to stay on top of things.

A Natural Fit for Creative and Tech-Savvy Teams

Discord’s informal vibe makes it a hit with creative teams, gamers, and smaller companies that don’t need constant formal meetings. It’s a platform where dynamic, creative communication thrives. If your team values a sense of community and a laid-back atmosphere over rigid corporate tools, Discord might just be your new best friend.

Integration: A Bit of a Mixed Bag

Here’s where things get a little tricky. Unlike Slack or Microsoft Teams, Discord doesn’t have a ton of official integrations for business apps. Most of its add-ons come in the form of user-created bots, which can be hit-or-miss when it comes to support. That said, it does integrate with tools like Trello, Asana, Google Drive, and Dropbox.

For more complex workflows, you can use Zapier to connect Discord with other apps. For instance, GitHub updates can be sent directly to Discord channels - a lifesaver for development teams. And if you’re a content creator, Discord’s integrations with Patreon, YouTube, and Twitch are excellent for staying connected with fans and subscribers.

While Discord offers a fun, community-first approach to communication, it’s not without its limitations. For a more polished and professional collaboration experience, Pebb still takes the cake.

5. Mattermost

When it comes to secure, self-hosted communication platforms, Mattermost is a standout option. Designed for organizations with strict security needs or those requiring tailored communication workflows, it offers a level of control and customization that’s hard to match.

Pricing That Grows with You

Mattermost keeps its pricing simple and scalable. The Free Plan is a solid starting point, offering unlimited message history, one-to-one and group chats, file sharing, and integrations - all at no cost. Need more features? The Professional Plan comes in at $10 per user per month, adding advanced permissions, compliance tools, and 24/7 support. For larger teams, the Enterprise E10 Plan starts at $15 per user per month, while the top-tier Enterprise E20 Plan offers custom pricing with enhanced compliance and support options. It’s a flexible model that lets you start small and upgrade as your needs evolve.

A Fortress for Security-Conscious Teams

If security is your top priority, Mattermost has you covered. It boasts features like end-to-end encryption, detailed permission controls, multi-factor authentication, single sign-on, and audit logs. You can access the platform through web browsers, desktop apps, and mobile devices - though some users have noted performance hiccups on mobile. With these tools, Mattermost is particularly well-suited for teams that need to balance robust security with customizable workflows.

A Favorite Among Development and Tech Teams

Mattermost really shines in tech-heavy environments. Its seamless integrations with tools like GitHub, Jira, and Jenkins make it a go-to for development teams. Here’s what a U.S. Air Force representative had to say about their experience:

"For us, using Mattermost offers a huge benefit in mission velocity and safety. We found that it also gave us a lot more time to fix cargo and fuel problems before the crew even shows up at the airplane."

Its open-source framework is another big draw, allowing teams to adapt the platform to their unique needs. With over 30,000 GitHub stars and contributions from more than 4,000 developers, the Mattermost community is both active and supportive [47, 59].

Integration Power with a Few Drawbacks

Mattermost offers a range of ways to extend its capabilities, from webhooks and slash commands to bots, APIs, and plugins. Plus, its "Slack-compatible" integrations make it easier for teams switching over from Slack. Through Zapier, it connects with over 700 tools [55, 59]. However, some users have pointed out that the interface, search functionality, and mobile app could use more polish.

With a strong rating of 4.25 out of 5, Mattermost is a great fit for tech-savvy teams that value security and flexibility. But if your team prioritizes simplicity and a sleek user experience, Pebb might be a better match.

6. Zulip

If you've ever felt overwhelmed by the chaos of group chats, Zulip might just be your saving grace. Its unique threading system organizes conversations by topic, keeping everything neat and accessible - even if your team is scattered across multiple time zones. This approach makes Zulip stand out in the crowded world of communication tools.

Pricing That Fits Any Team

Zulip’s pricing structure is designed to accommodate teams of all sizes and budgets. Their Free Cloud Plan gives you 10,000 searchable messages and 5 GB of file storage, all at no cost. For growing teams, the Standard Plan costs $6.67 per user per month - noticeably cheaper than Slack’s $8.75 starting price. Need enterprise-level features like SSO or custom domains? The Plus Plan is available (with a 10-user minimum). For those who prefer self-hosting, you can run Zulip on your own servers for free or upgrade to the Basic Plan for just $3.50 per user per month, unlocking unlimited mobile notifications. They also offer free Standard plans to eligible organizations.

Threading That Actually Works

Zulip’s threading system is a game-changer. It organizes conversations by stream and topic, allowing multiple discussions to happen simultaneously without the clutter you’d find in apps like Slack or Microsoft Teams.

The feedback from users is impressive. Jacinda Shelly, CTO at Doctor on Demand, shared:

"Zulip's unique threading saves me over an hour daily when collaborating with our distributed team of engineers and PMs across 7+ time zones".

Josh Triplett from the Rust Language team echoed this sentiment:

"Zulip lets us move faster, connect with each other better, and have interactive technical discussions that are organized, recorded, and welcoming to other people".

A Lifesaver for Remote and Distributed Teams

Zulip is built for asynchronous communication, making it ideal for remote teams. Unlike traditional chat tools that assume everyone is online at the same time, Zulip’s threading system allows team members to jump into discussions long after they’ve started. It also doubles as a self-documenting knowledge base, ensuring that key decisions and conversations are always easy to find. This is a huge advantage for startups and distributed teams trying to stay on the same page.

Integrations and Customization Galore

Zulip goes beyond threading with an impressive library of over 130 native integrations, plus thousands more through Zapier and IFTTT. Whether you use Jira, GitHub, or Trello, Zulip can connect seamlessly with your workflow. And because it’s 100% open-source, you get full transparency and the flexibility to customize the platform however you like.

The platform consistently ranks among the top 5 products in its category on review sites like Capterra and SoftwareReviews. It even simplifies the switch from other tools by letting you import data from Slack, Mattermost, and Rocket.Chat.

While Zulip excels at keeping conversations organized and efficient, it’s not a one-size-fits-all solution. If you’re looking for a platform that combines messaging with engagement features, Pebb might be the better fit. With a free plan and a premium option at just $4 per user, Pebb offers a balance of functionality and affordability that’s hard to beat.

7. Nextcloud Talk

When privacy and control are non-negotiable, Nextcloud Talk steps in to offer complete ownership over your messages, calls, and files.

Pricing That’s Easy to Understand

Nextcloud Talk keeps its pricing simple. The Standard plan starts at €40 per user annually (about $43 USD) for teams of 100 users. If you’re managing a larger group - 250 users or more - the cost drops to €30 per user per year (around $32 USD). There’s also a free self-hosted option, though you’ll need to factor in server expenses and the technical know-how to set it up and maintain it.

Frank Karlitschek, CEO of Nextcloud, sums up their mission perfectly:

"Companies need powerful collaboration tools – but most solutions are not GDPR-compliant and lock organizations into dependence on U.S. tech giants. We address the limitations of other platforms by delivering true digital sovereignty and full transparency".

On top of its competitive pricing, Nextcloud Talk puts a heavy emphasis on security, ensuring every interaction is protected.

Security You Can Trust

Nextcloud Talk goes the extra mile to keep your communications safe. It offers end-to-end encrypted video and audio chats, ensuring your conversations stay private. Unlike platforms like Microsoft Teams or Slack, which often route data through third-party servers, Nextcloud Talk keeps everything on your own infrastructure. This approach minimizes metadata exposure and gives you full control over your data.

The platform doesn’t just stop at security - it’s packed with practical features, too. From private and public calls to screen sharing and mobile access, it’s designed to handle the demands of everyday use while keeping your data locked down.

Seamless Integration and Customization

Nextcloud Talk works effortlessly alongside the rest of the Nextcloud suite, including Files, Groupware, and other productivity tools. Need to connect with external platforms? No problem. Nextcloud Talk bridges its rooms with channels on Slack, Microsoft Teams, Matrix, and XMPP, making migrations and external collaborations smooth and hassle-free.

Built for Teams That Value Privacy

For organizations with strict privacy requirements, Nextcloud Talk’s open-source design is a game-changer. It’s fully customizable, allowing teams to tailor the platform to their specific needs. Larger teams or those hosting webinars can also benefit from the High Performance Backend, which enhances connectivity and supports more participants. Plus, modern features like AI-driven chat summaries and federated calls add functionality without ever compromising security.

While Nextcloud Talk delivers a secure, self-hosted communication platform, it does require technical expertise and an investment in infrastructure. If your team prioritizes simplicity and cost-efficiency over managing servers, Pebb might be a better fit. With a free plan and premium features starting at just $4 per user, it’s an affordable, user-friendly alternative.

Platform Comparison Table

After exploring various Slack alternatives, it’s time to line them up side by side. Here’s a quick breakdown of pricing, features, and the types of teams each platform is best suited for:

Looking at the table, it’s easy to see why Pebb stands out. For just $4 per user/month, Pebb offers an all-in-one solution that includes work chat, a news feed, voice and video calls, a directory of employees, and tools for tasks and calendars. This combination of features makes it a strong contender for startups, non-profits, and remote teams - especially those keeping a close eye on their budgets.

What really sets Pebb apart is its ability to deliver professional-grade tools without the hefty price tag. For teams that need reliable communication and collaboration features without overspending, Pebb offers the perfect balance of affordability and functionality.

Conclusion

When it comes to picking the right communication tool, the goal is clear: find something that works seamlessly while keeping costs in check. In today’s world, where every dollar counts, the last thing you want is a tool that drains resources instead of fueling growth, supporting critical projects, or simply keeping the lights on.

This is especially true for remote work. Did you know that 41% of employees who shifted from office to remote setups cite communication as their top challenge? On the flip side, companies with solid internal communication are 25% more likely to see reduced employee turnover. That’s not just a financial win - it’s a game-changer for team morale and stability. To tackle these challenges, you need a tool that balances functionality and value.

Here’s where Pebb comes in. While other platforms might cater to niche needs, none bring together the same level of features and affordability as Pebb. When I weigh the options - features, pricing, and ease of use - Pebb consistently checks all the boxes.

"It combines everything - chat, tasks, news feed, knowledge, library - into one place, and it's incredibly affordable."

"I found it to be the perfect communication platform for remote teams. Pebb helped us unify communication in one place without the cost or complexity of bigger tools."
