MultiSlack
Nine Slack workspaces, one window, zero boundaries
Other apps cram your accounts into a sidebar you still click through one at a time, like an animal. MultiSlack shows up to 9 fully-isolated Slack workspaces at once — a 3×3 grid of obligations, each with its own session and cookies, no logging out to log in. You stop switching contexts and simply hold all of them, forever, like a small frightened god. Native macOS, fast, light/dark. Tested in humans (n=1, survived).
Too many Slack workspaces. The desktop app makes you click a little sidebar to switch between them one at a time, like an animal. Somewhere along the way, knowledge work quietly turned everyone into a load balancer made of meat — routing yourself between teams until something inside you 429s.
MultiSlack removes the switching. Up to 9 fully-isolated Slack accounts tiled into one window — a 3×3 grid of obligations, each with its own session. You stop changing contexts and simply hold all of them, forever, like a small frightened god.
(Getting it to behave was not without its challenges — but it behaves now.)
Is this good for humans? Unclear. The beta has been tested on one. They are mostly fine. The eye twitch is intermittent.

Who hunted MultiSlack?
MultiSlack was hunted by Tamas Kalman. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
