MultiSlack

About

While other apps squeeze your accounts into a sidebar, forcing you to click through them individually, MultiSlack displays up to nine completely separate Slack workspaces simultaneously. This 3 by 3 grid of responsibilities maintains independent sessions and cookies for each, eliminating the need to log out and back in. You cease switching between contexts and instead maintain them all at once, perpetually, like a minor terrified deity. It is a native macOS application, fast, and supports light or dark modes. It has been tested on a human subject, who survived the experience.
