8 Best Slack Alternatives

Key Features for Remote Team Tools

When looking at Slack alternatives for remote teams, several features play a big role in how well a collaboration platform performs.

The top platforms include threaded conversations, direct messaging, and channel-based communication. These tools help keep discussions organized and easy to search, solving issues like scattered messages, unclear task assignments, and the need for secure, scalable systems.

Video and Audio Integration

Reliable video and audio conferencing is a must for remote teams. The best platforms offer built-in video and audio features, so team members don’t have to juggle multiple apps.

Task Management and Organization

Task management tools - such as assigning tasks, setting deadlines, tracking progress, and sharing files - help teams stay in sync and keep projects moving forward.

Security and Data Protection

For remote teams handling sensitive information, security is a top priority. For example, Element provides end-to-end encryption and private server options to ensure data stays protected ^[2].

Integration Capabilities

Connecting with other business tools can significantly increase productivity. For instance, Google Chat works seamlessly with Google Workspace, while Microsoft Teams integrates with Office 365, making them great choices for teams already using these suites ^[3][2].

Scalability and Performance

Good platforms grow with your team. They offer reliable uptime, quick message delivery, efficient file sharing, and support for larger groups, ensuring performance doesn’t falter as your organization expands.

User Experience and Accessibility

A tool is only as good as its usability. Discord’s transition from gaming to business shows the importance of a simple, intuitive interface ^[2]. Platforms should also work smoothly across all devices to keep remote teams connected without hassle.

With these features in mind, let’s dive into the top free Slack alternatives for remote teams in 2025.

1. Microsoft Teams

Microsoft Teams is a go-to collaboration platform, especially for organizations already using Microsoft 365. Its free version offers a solid mix of features designed to keep remote teams connected and productive.

With high-quality video and audio for meetings and seamless calendar integration, scheduling is a breeze ^[2][3]. Plus, its tight integration with Microsoft Office apps allows teams to work on documents in real-time during calls or chats ^[2].

Here’s what the free version includes:

• A 10,000-message history limit
• Basic file sharing and 5GB of team storage
• Standard security tools

Microsoft Teams is built to accommodate multiple departments and team structures, making it a strong option for remote organizations ^[2]. Its user-friendly interface ensures a smooth onboarding process, while customizable workflows and notifications allow teams to tailor it to their needs ^[2].

The messaging system supports both direct messages and channel-based threads, keeping conversations organized and easy to track. For those needing more advanced tools, Microsoft offers affordable paid plans.

"Microsoft Teams combines familiarity, robust features, and Office integration, making it an easy transition for teams used to Slack."

Next, we’ll dive into how Google Chat provides a lightweight, integrated option for remote teams.

2. Google Chat

Google Chat works effortlessly with Google Workspace, letting teams collaborate on Docs, Sheets, and Slides directly within their conversations. For remote teams already using Google Workspace, it simplifies workflows by centralizing communication and file sharing in one place.

The platform offers straightforward collaboration tools without overcomplicating things. Teams can work on files in real-time within chats, cutting down on the need to switch between apps ^[2][4].

The free version covers the basics for small to medium-sized teams, though it doesn't offer much in terms of customization. Its clean and simple interface makes it easy for teams to get started ^[2].

Compared to Slack or Microsoft Teams, Google Chat focuses on simplicity rather than packing in features. This makes it a good option for teams looking for a lightweight tool ^[3]. The platform prioritizes essential communication over complex customization options.

Main benefits include:

• Real-time file collaboration
• User-friendly design
• Access across devices
• Strong security measures

That said, teams should weigh their specific needs against what Google Chat offers. While its integration with Google Workspace is a strong point, it might not be the best choice for those requiring more advanced features ^[2].

"Google Chat excels in offering essential communication tools with Google Workspace integration but may fall short for teams needing advanced features."

While Google Chat shines with its simplicity and Google Workspace integration, other platforms, like Discord, cater more to community-building. We'll dive into that next.

3. Discord

Discord has grown into a popular platform for team communication, especially for remote work. It blends text and voice features, making it a good fit for teams that rely on verbal communication to stay connected ^[2].

Its free plan is notably competitive, offering features like customizable text channels and always-on voice rooms. These tools allow teams to create virtual office spaces where members can collaborate in real time ^[3].

The platform’s voice channels are a standout, functioning like virtual meeting rooms where team members can join and leave as needed ^[2][3].

Discord also offers server management tools that let teams create structured workspaces with roles and permissions. This helps maintain organization and security, especially for larger groups ^[2].

When compared to Slack, Discord is more flexible for voice communication. However, it falls short in advanced integrations and has a 25MB file size limit on its free plan, which could be a challenge for teams sharing large files ^[2][4].

"Discord's strength lies in its ability to combine text-based communication with always-on voice channels, making it an excellent choice for teams that need fluid verbal collaboration throughout the day" ^[2].

For security, Discord includes two-factor authentication and encryption to protect team communications. Teams should take the time to configure these settings and establish clear usage guidelines for added safety ^[2].

While Discord shines in real-time communication, platforms like Element focus more on privacy and security, offering a different set of strengths for remote teams.

4. Element

Element is a platform designed with privacy and security at its core. Its advanced encryption ensures that sensitive data stays protected, making it a strong choice for remote teams managing confidential information.

Element combines secure messaging with features like organized channels (called rooms) and high-quality video conferencing. Its screen-sharing feature makes remote meetings smooth and efficient, while encryption remains a priority across all tiers, including the free plan.

The free version is well-suited for small teams, though it includes limits on storage and room capacity. For organizations that want full control over their data, Element offers a self-hosting option, giving it an edge over cloud-only platforms when it comes to privacy.

Teams can structure their work through topic-specific rooms, which streamline discussions and collaboration. While its integration options are fewer compared to platforms like Microsoft Teams, Element supports essential tools for remote work, ensuring productivity without sacrificing security ^[2]. By connecting with third-party tools, it helps teams centralize their workflows effectively.

"Element's use of the Matrix protocol and emphasis on end-to-end encryption set it apart from many other Slack alternatives. This makes it particularly appealing to teams that prioritize data security."

For privacy-conscious organizations, Element provides a secure communication platform. However, teams should evaluate whether the free plan's storage and user limits align with their needs. Paid plans are available for scaling, but the platform's primary strength lies in its secure and private communication features.

While Element emphasizes privacy, other platforms like Mighty Networks focus more on building community and engagement.

5. Mighty Networks

Mighty Networks combines team communication with tools for building a community, using its Spaces system. These Spaces allow teams to create specific areas for project discussions, training sessions, or even casual interactions, encouraging collaboration and stronger team connections.

The platform’s asynchronous features make it easy for team members in different time zones to stay involved. While the free plan includes key tools, it limits the number of members and certain functionalities, making it a good fit for smaller teams focused on engagement. For groups looking for more than just messaging, Mighty Networks offers features to build a connected and active community while still supporting professional collaboration.

With live streaming, events, and a course platform, Mighty Networks goes beyond standard chat tools. These features support both collaboration and team-building, though teams might need some time to learn how to use everything effectively ^[3].

"Mighty Networks offers additional features that Slack does not have, such as live events, live streaming, and a course platform. This makes it a more comprehensive tool for community building and engagement" ^[3].

While Mighty Networks shines in creating an engaging community, the next tool focuses on simplifying task-based communication for remote teams.

6. Flock

Flock offers a communication platform that blends messaging, video calls, and task management into one easy-to-use tool.

Flock helps streamline tasks with features like to-do lists, reminders, and polls, so there's no need for extra task management apps. The free plan includes group chats, video calls for up to 20 participants, 10GB of storage, and integrations with tools like Google Drive and Trello.

Its integrations with Google Drive, Trello, and GitHub make it easy to manage workflows in one place. The platform’s design is straightforward, making it accessible for new users, while the mobile app ensures remote teams stay connected wherever they are.

However, the 10GB storage limit and 10,000-message cap might be restrictive for larger teams. Still, Flock's all-in-one setup reduces the hassle of switching between multiple apps, which is a frequent challenge for remote teams.

"Flock addresses common challenges like communication breakdowns, lack of organization, and difficulty in finding information by offering a comprehensive platform with features like messaging, video conferencing, and task management."

While Flock focuses on merging communication with task management, Ryver takes a more structured approach to organizing workflows.

7. Ryver

Ryver is a platform that combines team communication and task management into one tool, making it a practical option for remote teams.

Ryver brings together messaging and task management, helping teams stay organized by centralizing conversations, task assignments, and progress tracking. The free plan includes secure messaging and basic task management features but has limits on storage and the number of users, making it a good fit for smaller teams.

For teams moving from Slack, Ryver offers a familiar setup with added task management features. It lets you organize channels, assign tasks, and monitor progress all in one place. Plus, integrations with tools like Google Drive and Trello help streamline workflows further.

The pricing for Ryver starts at $49/month for up to 12 users, which is something to consider as your team grows.

"Ryver emphasizes security by providing encrypted messaging and secure file sharing. This ensures that remote teams can collaborate safely, even when handling sensitive data."

While Ryver shines in real-time collaboration and task organization, Twist offers a different approach, focusing on asynchronous communication for remote teams.

8. Twist

Twist focuses on structured, asynchronous communication, making it a great fit for remote teams working across time zones. Its thread-based channel system helps teams keep discussions organized and locate information easily - especially useful for global teams.

Created by Doist (the team behind Todoist), Twist stands out by reducing message overload through its structured communication. While the free plan includes unlimited messaging and basic integrations, storage and integration options are somewhat limited. For remote teams, this setup ensures important conversations are easy to follow without the pressure of responding immediately.

The platform is designed to promote focused, meaningful discussions by cutting down on constant notifications - a common issue with many collaboration tools. This not only boosts productivity but also helps remote workers maintain a better balance between work and personal life.

"Twist's thread-based design ensures clarity and alignment, especially for teams navigating time zone differences."

While Twist shines in asynchronous communication, Chanty offers a mix of real-time messaging and task management for teams needing both options.

9. Chanty

Chanty combines real-time messaging with task management using a built-in Kanban board. This feature helps remote teams handle projects without constantly switching between apps. Unlike Slack, which relies on integrations for task management, Chanty integrates it directly into its platform, making workflows simpler for smaller teams.

The Kanban board provides a visual way to manage tasks, allowing teams to create, assign, and track tasks directly within conversation threads. This setup is particularly useful for remote teams working on detailed projects.

Chanty supports over 75,000 teams worldwide. Its file-sharing tools and integrations with platforms like Google Drive and GitHub make collaboration easy without needing to leave the app. The search tool lets users filter by person, date, or keyword, making it quick to find important details.

"Chanty's integrated task management and messaging features significantly improved team collaboration, leading to a 30% reduction in project completion times", shared a remote marketing agency that adopted the platform.

For teams needing extra storage or more integrations, paid plans are available starting at $3 per user per month. Chanty also offers mobile apps to keep team members connected on the go.

While Chanty stands out for blending messaging and task management, Pumble provides a more classic collaboration option with unlimited users and storage.

10. Pumble

Pumble offers unlimited chat history and file storage, a feature that's hard to find among free Slack alternatives. Its user-friendly design organizes conversations through customizable channels and threads, making it easier to keep discussions on track and searchable.

With Pumble, teams can set up channels for specific projects, departments, or even casual chats. The unlimited storage is especially useful for remote teams that frequently share large files, making it a solid option for document-heavy workflows.

The platform also supports basic video calls for quick team check-ins or one-on-one meetings. While the free plan includes essential app integrations, advanced integration options are only available with paid plans.

For remote teams that need unlimited storage and tools for long-term collaboration, Pumble is a practical choice. On the other hand, if your team prefers more control over communication systems, Rocket.Chat offers a self-hosted alternative.

11. Rocket.Chat

Rocket.Chat is an open-source platform designed for remote teams that need self-hosting, strong security, and full control over their data. It offers features like encryption and multiple authentication methods to prioritize privacy.

Rocket.Chat is particularly suited for teams managing sensitive data or working in industries with strict compliance rules. Its open-source nature allows customization of security settings, such as encryption and authentication, to fit specific requirements.

The platform supports real-time messaging, threaded conversations, and file sharing, along with integrations for tools like project management and CRM software. However, self-hosted setups may demand IT expertise for configuring servers and managing updates. The free plan offers core features but comes with limits on storage and users. Paid plans start at $3 per user per month.

Rocket.Chat holds a solid 4.5/5 rating from 245 users on Gartner Peer Insights, with its security and customization options earning the most praise. For teams focused on data control and customization, Rocket.Chat is a strong alternative to Slack.

"While Rocket.Chat excels in security and customization, teams seeking a simpler, cloud-based solution may find Clariti a better fit."

12. Clariti

Clariti brings together emails, chats, and files into one workspace, making remote team collaboration more streamlined. Its context-based communication system organizes conversations and documents by project, giving teams a single view to access emails, chats, and files together. This tackles the common issue of scattered communication across multiple platforms.

The free version provides a solid set of collaboration tools with a user-friendly interface. Unlike many other tools, Clariti reduces time wasted switching between email and chat apps. Its task management system lets teams handle task creation, assignment, and tracking directly within project contexts, ensuring smoother workflows.

One limitation to note is the restricted storage in the free plan, which could be a hurdle for teams that often share large files. However, Clariti shines in preserving communication history and simplifying workflows, especially for teams transitioning from email-heavy setups.

"Clariti's innovative approach to integrating different communication channels and its focus on context-based communication align with expert recommendations, positioning it as a superior alternative to Slack for remote teams" ^[1]

For remote teams dealing with fragmented communication, Clariti offers a practical way to combine email management, chat, and task tracking in one place. Its project-based organization of communication makes it an excellent choice for teams aiming to keep clear project histories while boosting collaboration.

Clariti stands out as a strong option for teams looking to centralize their workflows, particularly those that rely heavily on email integration. It’s a compelling addition to the list of Slack alternatives.
