Cheatsheet Pages / Desubscribe — Free SaaS Alternatives
Replace Slack Pro ($87/yr per person) with Mattermost — save $87 a year

git clone https://github.com/mattermost/docker && cd docker && docker compose -f docker-compose.yml -f docker-compose.without-nginx.yml up -dGood to know
After it starts, open http://localhost:8065 and create the admin account. For a 10-person team this swap alone saves $870 a year.
