Supercapybara / Railway Templates
Mattermost
Mattermost Team Edition is an open-source, self-hosted Slack alternative: channels, threads, direct messages, file sharing, search, integrations and mobile and desktop clients, running on infrastructure you control. This template deploys it with the system administrator account already created, because a stock Mattermost deploy contains no user and hands the system_admin role to whoever opens the URL first.
Disclosure: deploy links carry the author's Railway referral code — the author receives a usage kickback when you deploy. The template itself is free to deploy; Railway usage charges apply.
