16 Open-source Self-hosted Web Chat Systems

A self-hosted chat system refers to a chat application that can be installed and run on a user's own servers or infrastructure, rather than relying on a third-party service. This gives users full control over their chat data, privacy, and customization options. Here are some benefits of self-hosted chat systems for productivity:

  3. Integration: Self-hosted chat systems can be seamlessly integrated with other internal tools and systems, such as project management platforms or customer support systems. This allows for efficient collaboration and streamlined workflows.

Advantages for Teams:

  1. Enhanced Collaboration: Self-hosted chat systems provide teams with a centralized platform for communication, enabling real-time collaboration and quick decision-making. Team members can easily share information, discuss ideas, and coordinate tasks.
  2. Privacy and Security: By hosting the chat system internally, teams can ensure that their conversations and data are secure. They have full control over access permissions and can implement additional security measures as needed.
  3. Reduced Reliance on External Services: Self-hosted chat systems eliminate the reliance on third-party services, reducing the risk of service interruptions or data breaches. Teams can have peace of mind knowing that their chat system is under their direct control.
