Open Source Collaboration & Communication Software
Collaboration & Communication software provides shared environments for real-time messaging, video conferencing, and joint document editing. These tools centralize team chat history, project notes, and digital whiteboards to prevent information from being scattered across different platforms. This type of software serves organizations and teams that need to manage internal discussions and shared knowledge bases. Self-hosting these apps ensures that sensitive company conversations and private project files remain on internal servers rather than on external corporate clouds.
This page lists 94 open source tools in the Collaboration & Communication category. The most popular are Excalidraw, AppFlowy and Affine. Most use the AGPL-3.0 or Apache-2.0 license, and 74 offer an official Docker image.
