WhatsApp struggles to meet workplace needs in 2025. Businesses are switching to platforms designed for professional communication, prioritizing security, collaboration, and scalability. Here’s a quick look at the top alternatives:

• Pebb: Free for up to 1,000 users, $4/month for premium; includes chat, tasks, calendars, and integrations.

• Slack: Great for integrations and project management, but pricier ($6.75+/user/month) with limited free features.

• Microsoft Teams: Ideal for Microsoft 365 users; strong video features but complex pricing ($4–$22/user/month).

• Workvivo: Focused on employee engagement; custom pricing, no free plan.

• Staffbase: Enterprise-focused with advanced tools; starts at $30,000/year.

Quick Comparison:

Summary: For budget-friendly, feature-rich communication, Pebb is a standout choice. Larger companies may prefer Microsoft Teams, Workvivo, or Staffbase based on their specific needs.

What Are The Best Alternatives To WhatsApp? - Be App Savvy

1. Pebb

Pebb is the only platform offering a free, all-in-one communication solution tailored for professional teams. While apps like WhatsApp focus on basic messaging, Pebb goes several steps further, delivering a complete communication toolkit without the usual security concerns or missing features often found in consumer apps.

With Pebb, you get everything in one place: work chat (with unlimited history), news feeds, tasks, calendars, and groups. This unified setup makes it easy for teams to organize their projects, departments, or discussions into dedicated spaces while maintaining full control over their communication environment.

Designed with mobile users in mind, Pebb ensures a smooth transition from WhatsApp. You can effortlessly switch between mobile and desktop without losing track of conversations or updates.

Pricing

The Standard plan is completely free for teams of up to 1,000 employees, making it ideal for organizations of any size, even those with tight budgets.

For teams needing more advanced tools, the Premium plan is just $4 per user per month - a fraction of the cost of most enterprise platforms. This plan unlocks features like voice and video calls, advanced analytics, unlimited administrators, enterprise SSO, and premium support.

Integration Capabilities

Pebb now works seamlessly with over 20 new Zapier triggers, making it easier than ever to automate workflows. For instance, you can:

• Track deals in Google Sheets.

• Automatically send documents to DocuSign.

• Trigger email campaigns when deals hit specific stages.

• Push property data to accounting systems after sales close.

• Build custom dashboards in Google Data Studio or Power BI.

These integrations save time and streamline processes, especially for businesses managing complex workflows.

Scalability

Whether you're a small team or a large enterprise, Pebb grows with you. The free plan supports up to 1,000 employees, while the Premium plan adds enterprise-level features like advanced permissions and SSO integration. Start with basic tools like chat and news feeds, then expand into advanced options like analytics, voice and video calls, and enhanced work chat as your needs evolve. This flexibility eliminates the hassle and expense of switching platforms during growth.

Up next, we’ll see how other platforms compare to Pebb’s robust offering.

2. Slack

Slack continues to be a go-to platform for workplace communication. While it boasts a strong reputation, its pricing and security approach stand apart from Pebb's more unified offerings.

One notable impact of Slack is its ability to cut down on internal emails. Teams report a 30–40% reduction in email volume after adopting the platform, showcasing its effectiveness in streamlining communication. However, despite its market dominance, Slack has faced some security challenges that have raised concerns.

Security and Compliance

Slack provides enterprise-level security features, including compliance with GDPR and FedRAMP Moderate standards. It encrypts data both in transit and at rest by default, and admins can enforce two-factor authentication for all users [15, 16].

However, high-profile breaches have exposed vulnerabilities. In July 2024, the hacking group Nullbulge accessed 1.1TB of sensitive data from Disney's Slack channels, including login credentials and unreleased projects. Similarly, EA Games suffered a breach where attackers stole Slack cookies and used social engineering to bypass multi-factor authentication, resulting in the theft of over 780GB of source code.

"OAuth Is Often the Weakest Link: Most Slack compromises stem from OAuth abuse - review every integration like you would a cloud IAM role", advises Dvir Shimon Sasson, Director of Security Research at Reco.

While Slack offers advanced features like Enterprise Key Management (EKM) and audit log APIs, these are often locked behind higher-tier plans. Notably, Slack does not provide default end-to-end encryption - this level of security is only achievable for enterprise customers using EKM.

Integration Capabilities

One of Slack's standout features is its extensive integration ecosystem, with more than 2,600 apps available in its marketplace. The platform supports over 600,000 custom integrations weekly, connecting tools for project management, CRM, and file sharing. Popular integrations include Google Calendar for managing schedules, Salesforce for CRM workflows, and Zoom for video calls.

Slack also offers a Workflow Builder to help teams automate repetitive tasks. Interestingly, native integrations tend to outperform third-party options in user satisfaction by 30%.

Scalability

Slack is designed to scale with businesses of all sizes, offering tiered plans to accommodate different needs. The free plan covers basic messaging, while paid plans unlock features like unlimited message history, guest access, and enterprise-grade security tools. For large organizations, the Enterprise Grid provides centralized management across multiple workspaces. However, this custom pricing model can become quite expensive as teams grow.

Pricing

Slack's pricing starts at $6.75 per user per month for the Pro plan, which is nearly double the cost of Pebb's $4 premium plan. The Business+ tier ranges from $15 to $18 per user per month, and Enterprise Grid requires custom quotes. For budget-conscious teams, Slack's pricing can be a barrier. Furthermore, its free plan is fairly limited compared to Pebb's offering, which supports up to 1,000 employees without cost.

Next, we'll dive deeper into Slack's pricing structure to see how it stacks up against Pebb.

3. Microsoft Teams

Microsoft Teams stands out as a major player in workplace communication, built on the Microsoft 365 ecosystem. However, its pricing often exceeds Pebb's $4 per user model.

Security and Compliance

Microsoft Teams is rooted in the Microsoft 365 platform, offering a robust security setup. Features include team-wide two-factor authentication, single sign-on via Microsoft Entra ID, and encryption for data both in transit and at rest. The platform also integrates with Microsoft Purview compliance tools, such as retention policies, data loss prevention (DLP), eDiscovery, legal hold, and audit log search. Mobile application management is available through Microsoft Intune. For organizations needing extra encryption, the Customer Key feature allows for customer-provided encryption keys.

Additionally, Teams uses Microsoft Purview Information Barriers and sensitivity labels to manage access to confidential content. Microsoft Defender for Office 365 further enhances security by protecting Teams environments from potential threats.

"Security in Teams isn't just a technical consideration - it's a business-critical priority." – Orchestry.com

In February 2025, Teams rolled out phishing alerts for external messages. This feature prompts users with an "Accept or Block" option when receiving a message from an external sender for the first time, helping to block suspicious contacts and reduce risks. These security measures align with Teams' integration of productivity tools, ensuring a safe and efficient user experience.

Integration Capabilities

Teams is designed to work seamlessly with Microsoft 365 apps, while also allowing workspace customization through tabs, connectors, and bots. Beyond Microsoft's own tools, Teams integrates with third-party platforms like Trello, Salesforce, and HubSpot. Its Bot Assistants are particularly helpful for automating repetitive tasks, making workflows more efficient.

At Ignite 2023, Microsoft announced significant investments in AI for Teams, further enhancing its capabilities.

"Microsoft Teams brings together people, conversations, and content – along with the tools teams need to collaborate effectively." – Microsoft

Scalability

Microsoft Teams provides flexibility for organizations of all sizes. Standard meetings can host up to 1,000 participants with full engagement (audio, video, and screen sharing) and up to 10,000 in view-only mode. For even larger events, Teams Premium supports up to 50,000 interactive participants during town hall meetings.

Microsoft 365 plans offer tailored options: Business plans are designed for teams with up to 300 users, while Enterprise plans cater to larger organizations. For instance, Teams Essentials supports meetings with up to 300 participants, while Enterprise plans can host up to 1,000 participants. While Teams offers impressive scalability, its pricing can be a concern compared to Pebb's more straightforward cost structure.

Pricing

Teams Essentials starts at $4.00 per user per month, but the price increases significantly for more advanced plans:

• Microsoft 365 Business Basic: $6.00 per user per month (annual billing)

• Microsoft 365 Business Standard: $12.50 per user per month (annual billing)

• Microsoft 365 Business Premium: $22.00 per user per month (annual billing)

For those who prefer monthly billing, a 5% premium applies. Additionally, Microsoft has introduced licensing changes in the EEA and Switzerland, where Teams has been unbundled from some Microsoft 365 suites, adding complexity to the pricing structure.

4. Workvivo

Workvivo is an employee experience platform that blends communication and engagement tools. However, unlike Pebb's straightforward $4 per user pricing, Workvivo operates on a custom pricing model.

Security and Compliance

Workvivo takes security seriously, using an Information Security Management System (ISMS) to stay compliant with ISO 27001 and SOC 2 standards. The system ensures employees are aware of their security responsibilities and follow strict policies.

"Enterprises of every scale and scope demand that their data is at all times collected, processed and stored securely whilst satisfying all legal, industry and regulatory requirements." – Workvivo Security Statement

The platform also complies with global data protection laws, including GDPR, and offers features like customizable user permissions, ensuring employees only access relevant information. Security measures include end-to-end encryption, Two-Factor Authentication (2FA), and regular audits by independent third-party firms.

In May 2025, Workvivo AI introduced regional data processing, enabling AI-related tasks to be handled within specific geographic locations. This helps meet privacy regulations and enhances performance for organizations operating in regions with diverse data protection rules.

Integration Capabilities

Workvivo supports over 40 integrations, connecting with tools like Zoom, Google Workspace, Microsoft 365, and Salesforce. It also works with document management platforms such as SharePoint, OneDrive, Google Drive, Box, and Confluence. For identity management, it integrates with solutions like Active Directory and Okta.

A standout feature is its ability to push content to communication tools like Microsoft Teams and Slack. Additionally, Workvivo offers flexible APIs and developer tools for businesses needing custom workflows.

In April 2025, the platform added manual post translations for updates, shout-outs, and announcements. This feature allows users to manually create and edit translations, ensuring accuracy - especially in industries where precise communication is critical for compliance or safety.

These integrations and features make it easier for teams to adapt as their needs evolve.

Scalability

Workvivo is designed to support businesses of all sizes, from small teams to large enterprises. Its regional data processing capabilities not only improve performance but also address local data residency requirements.

Pricing

Unlike Pebb's clear $4 per user pricing, Workvivo uses a custom pricing model based on factors like company size, feature needs, and implementation complexity. While this approach offers flexibility, it can make budgeting less predictable and may be more expensive for smaller teams. Pricing details are only available through their sales team.

5. Staffbase

Staffbase is a communication platform tailored for large enterprises, serving more than 2,000 businesses worldwide. While Pebb offers a straightforward $4-per-user model, Staffbase takes a more expansive approach with three distinct modules: Employee App, Front Door Intranet, and Employee Email.

Security and Compliance

Staffbase prioritizes security with enterprise-level protections, including customizable settings and regional hosting options in the EU, US, and Australia. These hosting regions meet ISO 27001 and SOC 2 standards, ensuring robust data protection.

The platform also supports compliance with major regulations like GDPR for European operations, HIPAA (leveraging ISO 27001 certification and Business Associate Agreements), and CCPA as a service provider. Businesses can select hosting regions based on their specific data residency and regulatory needs.

Integration Capabilities

With support for over 150 integrations, Staffbase connects seamlessly with tools like Microsoft 365, SharePoint, and Box. This allows for efficient data synchronization and easy content embedding.

"The strong partnership between Staffbase and Microsoft is key. Staffbase provides a digital identity for >300k frontline workers, while Microsoft provides a future-proof foundation for collaboration." – Global Director Employee Experience, DHL

Scalability

Designed with large organizations in mind, Staffbase requires a minimum deployment of 1,000 employees. Its scalability is evident in implementations like Team Cowabunga, where over 2,500 employees use its social intranet, and Seaboard Triumph Foods, where 196 employees actively engage with the app daily, resulting in a noticeable boost in engagement rates. However, this level of scalability comes with a higher price tag, as outlined below.

Pricing

Staffbase's pricing starts at $30,000 per year for a minimum of 1,000 employees, making it a premium option compared to Pebb’s $4 per-user model. Each module - Employee App, Front Door Intranet, and Employee Email - is priced individually, though bundle discounts are available for organizations combining multiple modules. Despite the high cost, Staffbase has earned strong reviews on Capterra, with an overall rating of 4.7/5 and a 4.5/5 score for value for money, reflecting its appeal to enterprise-scale clients.

Platform Advantages and Disadvantages

After diving into the details, it’s clear that each platform brings its own mix of benefits and challenges when it comes to professional communication. Here’s a quick rundown of what each platform does well - and where it might fall short.

Pebb is the go-to for budget-conscious teams. Its free plan supports up to 1,000 employees and includes unlimited message history, work chat, a news feed, and a directory. Need more? The premium plan costs just $4 per user per month and adds features like advanced analytics and voice/video calls. The trade-off? The free plan offers limited admin controls and fewer data management options.

Microsoft Teams shines for companies already invested in Microsoft 365. It offers smooth integration and excellent video conferencing. According to Forrester Consulting, Teams can cut meeting times by 17.7% and boost employee productivity by 8.3%. However, it’s not all smooth sailing. New users often face a steep learning curve, and without a Microsoft 365 subscription, its capabilities are limited. Plus, it can be resource-heavy, which might not suit smaller organizations.

Slack is perfect for project-driven teams, thanks to its extensive third-party integrations and powerful search tools. Its channel-based system keeps collaboration organized, and threading makes conversations easy to follow. But it’s pricier than Pebb, limits message history on the free plan, and doesn’t quite match competitors when it comes to video features.

Workvivo is all about keeping employees engaged and recognized. It’s a top pick on G2 for internal communications, offering a robust news feed and advanced analytics - ideal for large enterprises focused on workforce engagement. The downsides? It’s expensive, with no free plan, and its implementation process can feel overwhelming for smaller teams.

Staffbase caters to large organizations with its mobile-first design and strong content management tools. It even offers regional hosting options in the EU, US, and Australia. But with a minimum annual cost of $30,000, it’s not for everyone. It also lacks video call functionality and offers limited chat features compared to all-in-one solutions like Pebb.

Here’s a table to make it easier to compare:

For small to mid-sized businesses looking for a feature-rich option without overspending, Pebb delivers excellent value. On the other hand, platforms like Staffbase and Workvivo are better suited for large enterprises with bigger budgets and more complex communication needs.

Conclusion

Finding the right workplace communication platform means understanding what your team truly needs and how much you’re willing to spend. A staggering 86% of employees point to poor communication as the main reason for workplace failures. That’s a stat no business can afford to ignore.

For small to mid-sized businesses, Pebb offers unbeatable value. Its free plan supports up to 1,000 employees, offering unlimited message history, work chat, and a news feed - features that competitors like Slack restrict in their free versions. And when your team grows, upgrading to Pebb’s premium plan is a no-brainer. At just $4 per user per month, you unlock voice and video calls, advanced analytics, and enterprise-grade security - all at a price that’s hard to beat.

For larger enterprises already invested in ecosystems like Microsoft 365, Microsoft Teams might make sense. But even then, Pebb holds its ground as an all-in-one solution that’s packed with features and delivers exceptional value for both frontline and office teams alike.

When weighing your options, think about what matters most: affordability, ease of setup, and a feature set that covers all the bases. And remember, poor communication doesn’t just hurt morale - it’s costly. Disengaged employees are responsible for $8.9 trillion in lost productivity worldwide.

The good news? You don’t have to start big. Try Pebb’s free plan to see how it fits your team, and upgrade only when you’re ready. If you’re looking for a platform that prioritizes security, rich features, and cost efficiency, Pebb is the smart choice. Don’t let communication gaps hold your team back.
