Top 10 Best Apps Like Slack in 2025

Collaboration tools have completely changed how we work in the digital age, and Slack has been at the forefront of this transformation for years. However, as technology evolves, so do our needs. Teams today want more flexibility, tighter integrations, simpler interfaces, and sometimes even lower costs.

That is why looking at alternatives to Slack in 2025 makes sense. In this guide, I will take you through the ten best apps like Slack that not only keep up with modern demands but also bring fresh features to the table.

Slack is a business communication platform designed to make teamwork faster, easier, and more organized.

Instead of relying on long email threads, Slack provides real-time messaging, file sharing, and collaboration in one place. Teams can create channels for different projects or topics, keeping conversations structured and searchable.

It also supports direct messaging, audio and video calls, and integrates with thousands of apps like Google Drive, Trello, and Zoom. Slack’s user-friendly interface allows teams to stay connected and productive whether working remotely or in the office.

All these aspects make it a central hub for modern workplace collaboration and communication.

In the under section, I have mentioned the top 10 best apps like Slack that can help you in collaboration between different team members while working on a project.

1. Microsoft Teams

When people talk about Slack alternatives, Microsoft Teams is often the first option that comes to mind. It is not just another chat app; it is a complete hub for teamwork within the Microsoft 365 ecosystem. If your organization already uses Outlook, Word, Excel, or OneDrive, Teams feels like a natural extension, as it is one of the top project management tools.

• Seamless Office Integration: One of the strongest reasons I recommend Teams is its deep integration with Microsoft’s productivity suite. You can edit Word documents, update Excel sheets, and collaborate on PowerPoint presentations without leaving the chat.
• Built-in Video Meetings: Teams combines messaging with high-quality video meetings. Scheduling calls, recording sessions, and even hosting webinars is smooth and reliable.
• Scalability for Enterprises: Whether you are running a small startup or a global enterprise, Teams has the ability to scale. It supports thousands of users and multiple departments under a single umbrella.

2. Google Chat

Google Chat, part of Google Workspace, has grown into a polished and reliable communication tool by 2025. It suits teams that prefer simplicity and depend heavily on Gmail, Drive, and Calendar.

• Integration with Workspace: Every message, file, or discussion can easily connect to Google’s apps. You can attach files from Drive, set reminders on Calendar, and manage emails alongside your chats.
• Straightforward Interface: I find Google Chat appealing because of its clean design. Unlike some overloaded apps, it is easy to navigate and does not overwhelm new users.
• Spaces for Collaboration: Google introduced Spaces to organize conversations. This feature helps keep discussions project-based and ensures that topics never get lost in the flood of messages.

3. Rocket.Chat

For teams that prioritize control, Rocket.Chat is a standout option. It is open-source, which means you can host it yourself and customize it to your needs. That’s the reason I call this as one of the best office communication apps.

• Complete Data Ownership: If your company works with sensitive data, Rocket.Chat gives you the confidence of keeping everything on your own servers.
• Flexible Customization: I appreciate how much flexibility this platform offers. You can modify themes, add integrations, or even tailor its functionalities to match your workflow.
• Community and Enterprise Support: Rocket.Chat has a vibrant community that constantly improves the platform. For enterprises, premium support and advanced features are also available.

4. Mattermost

Mattermost is another open-source tool that thrives in environments where compliance and security matter most. It is widely adopted in industries such as defense, healthcare, and finance.

• On-Premise Deployment: Unlike Slack, which is cloud-first, Mattermost allows you to deploy everything on-premise. It provides unmatched control over your data.
• Strong Security Features: Two-factor authentication, encrypted messaging, and advanced compliance options make Mattermost an excellent choice for secure industries.
• Workflow Integration: Mattermost also integrates with tools like GitHub, Jira, and Trello, which makes it a favorite among developer teams.

5. Chanty

If you are a small or medium-sized business that finds Slack too costly, Chanty might be your best bet. It is lightweight, affordable, and designed for ease of use.

• Simple Learning Curve: I like how easy it is for teams to get started with Chanty. There is little need for training, and the interface feels welcoming.
• Task Management Built-In: Chanty includes task features, meaning you do not need a separate project management app. It is especially useful for smaller teams.
• Unlimited Message History: Unlike Slack’s free plan, Chanty allows unlimited chat history, which means you never lose important conversations.

6. Zoho Cliq

Zoho Cliq is part of the larger Zoho ecosystem, which includes CRM, accounting, and project management tools. It is perfect if you want an all-in-one business suite.

• Unified Business Platform: Using Cliq means your chat integrates naturally with Zoho’s other products. Sales teams, for instance, can directly pull data from the CRM into their conversations.
• Affordable Pricing: Zoho is known for being cost-effective. Cliq continues this trend to become an attractive solution for businesses on a budget.
• Automation and Bots: Cliq allows you to create bots and automate repetitive tasks, and save both time and effort.

7. Discord

Originally built for gamers, Discord has transformed into a powerful collaboration app for communities and small teams.

• Real-Time Voice Channels: I find Discord’s always-on voice channels unique. They create a sense of presence, like working in a virtual office.
• Rich Media Sharing: Whether it is images, videos, or live streams, Discord handles multimedia content extremely well.
• Strong Free Tier: Unlike many competitors, Discord offers an impressive range of features in its free version, which is a big plus for startups or hobby projects.

8. Pumble

Pumble is one of the newer names in the collaboration space, but it has gained attention because of its generous free offering and simplicity.

• Unlimited Message History: The free plan allows teams to access all chat history without restrictions, which sets Pumble apart.
• Easy Transition from Slack: If you have used Slack, Pumble’s interface will feel familiar, making the switch painless.
• Great for Small Teams: I recommend Pumble especially for small to mid-sized businesses that need reliable communication without heavy costs.

9. Troop Messenger

Troop Messenger provides a balance of chat, video, and productivity features at a competitive price point.

• Versatile Communication Options: From text messaging to voice and video calls, Troop Messenger covers the basics effectively.
• Cross-Platform Access: It works across mobile, desktop, and web, and ensures teams can stay connected regardless of device.
• Secure Collaboration: Troop Messenger includes features like end-to-end encryption and self-destruct messages, which appeal to privacy-conscious teams.

10. Blink

Blink is a relatively new entrant focused on companies with a large number of frontline or deskless workers.

• Employee Engagement Features: What makes Blink different is its focus on engaging employees, not just enabling communication. It has surveys, announcements, and recognition tools.
• Mobile-First Design: Since many frontline workers rely on mobile phones, Blink’s mobile experience is smooth and intuitive.
• Centralized Hub: Blink acts as a one-stop platform where employees can access policies, schedules, and updates alongside their chat conversations.

These are the details about the top 10 best apps like Slack you can use for comfortable team communication.

The world of team communication has grown far beyond what Slack first introduced. While Slack is still powerful, the alternatives in 2025 are more diverse, cost-effective, and adaptable to specific needs. Microsoft Teams and Google Chat are excellent if you want seamless integration with productivity suites.

Rocket.Chat and Mattermost are for those who demand control and security. Chanty and Pumble are perfect for budget-conscious teams. Discord suits creative communities, while Zoho Cliq, Troop Messenger, and Blink address unique organizational needs.

When you understand your priorities, you can choose the best Slack alternative that ensures your team stays productive and connected.
