Campfire

Campfire is an open-source, self-hosted group chat system designed as a direct alternative to popular but costly services like Slack and Microsoft Teams. Its core value proposition lies in eliminating recurring subscription fees and providing users with complete control over their communication infrastructure and data. The tool offers fundamental chat features such as public and private rooms, direct messaging, @mentions, and mobile support, ensuring a familiar user experience for anyone accustomed to modern chat applications. What sets Campfire apart is its self-hosted nature and the availability of its full source code under the MIT License. This empowers users to deploy the application on their own servers, whether on-premise or in the cloud, and customize it to their specific needs. It's packaged as a Docker container, simplifying deployment with a single command, and even handles automatic SSL certificate setup. This approach not only reduces operational costs but also provides unparalleled data sovereignty and the flexibility to integrate or modify the system as desired, making it an ideal choice for organizations prioritizing control, privacy, and cost efficiency.
