Mattermost is one of the popular collaboration platforms with advanced messaging and chat functionalities. It is an open-source platform, and its features can be customized to meet different business requirements.
Yet, for many privacy-oriented and personalization-focused businesses and organizations, Mattermost has limited capabilities when it comes to scalable external communication with vendors, customers, and more.
In this blog, we review some of the best Mattermost alternatives with equal or exceeding abilities when offering a secure messaging platform.
Where does Mattermost excel?
Mattermost is widely recognized as a developer-first collaboration platform with advanced security features. Here's what makes Mattermost so popular and well-received:
1. Customization
A notable advantage of using Mattermost is that it is open-source software that can be customized to some extent to match various business requirements. Its source code is written in Golang, and businesses can alter the server or web app code to deliver additional functionalities.
2. Integration support
Mattermost can be integrated with the sales, CRM, and other business tools you already use, so you don’t have to switch between multiple platforms. You can automate routine tasks and build custom flows with deep tool integrations.
3. Highly secure
Mattermost has advanced security features and is compliant with the principles of GDPR and CCPA. It offers encryption in transit and at rest, multi-factor authentication, role-based user control with custom permissions, SAML-based single sign-on (SSO), and more, to ensure the safety and security of data.
4. Self-hosted platform
Mattermost offers self-hosted deployment and database ownership, making it appropriate for businesses dealing with sensitive data and functioning in regulated industries like Healthcare, Financial Services, and Government.
Why should you consider a Mattermost alternative?
Though Mattermost can be customized and integrated with existing third-party tools, some limitations motivate businesses to explore alternatives. Here are some of the crucial gaps:
1. Restrictive license
Mattermost offers a restrictive MIT-COMPILED-LICENSE, which means that businesses that alter the source code must enter into agreements like AGPLv2.
This means your specific conversion-worthy customizations will be in public and displayed to everyone, including your competitors. And every business likes to keep their cards close to the chest.
2. Limited features for external communication
Though it has advanced features for internal business collaboration, Mattemost has limited functionalities for communication with customers, partners, suppliers, and other external parties.
3. Limited scalability
Mattermost uses monolithic architecture, which is tightly coupled and complex to understand. It restricts the scalability of the collaboration tool, which is a limitation for growing businesses. In that case, businesses explore Mattermost alternatives that support scalability.
