Mattermesh

Mattermesh is an early-stage community project based on Mattermost.

Important note:

• we intentionally build from a non-enterprise baseline so patches can be applied and maintained with fewer conflicts
• this project does not claim to rewrite licensing terms
• if a legal expert wants to help review or propose a clean licensing path, contributions are very welcome

Current focus:

• implement SSO support through a dedicated patch
• remove restrictive user limits
• keep the setup simple with Docker Compose

Status:

• not production-ready
• looking for contributors
