HermesSEG
A self-hosted Communication & Social app you can run on your own server.
HermesSEG is a self-hosted communication platform that you run on your own server instead of renting it as a cloud service. Self-hosting it means no per-user subscription and no third-party cloud holding your information.
Its public repository on GitHub currently shows 137 stars, a useful signal of community interest. Repository activity was last recorded on Aug 22, 2026, and the project is classed as actively maintained in our snapshot.
Before you switch
Communication tools only work if your people can reach them. Check guest access, mobile apps, and federation or bridging support before migrating a community. Self-hosting gives you the data and the rules, but someone has to own updates and moderation.
Like every project listed on SelfHosted, HermesSEG is developed in the open — you can read the code, follow development, and even contribute. Check the system requirements and the project’s own documentation linked on this page before installing.
