Want to replace Slack (Team chat) with software you run and own? These 3 Nomad Packs give you a batteries-included, host-networked deployment on HashiCorp Nomad — one command to add the registry, one to run.

Mattermost — a self-hosted team chat and collaboration platform (a Slack alternative) with channels, threads, file sharing, and integrations. Deployed as an all-in-one host-networked Nomad job: a PostgreSQL sidecar plus the Mattermost Team Edition server with config/data/plugins volumes.
Synapse — the reference Matrix homeserver for secure, decentralized chat. Runs with an embedded SQLite database and auto-generates its config on first start. Deployed as a single host-networked Nomad service.
ejabberd — a robust, scalable XMPP (Jabber) server for real-time chat, group chat (MUC), presence and push, with a web admin. Deployed as a single host-networked Nomad service.
