MySlack
An unofficial, lightweight Slack client for macOS with channels, threads, reactions and files.

About
An unofficial Slack client for Apple Silicon Macs, drawn with MyGo's native UI: no Electron, no web view, about 85 MB of memory when idle. It shows channels, direct messages and threads with real-time updates, reactions, file downloads, notifications and an unread count on the Dock. It signs in with a session token from Slack's web client, which Slack's terms may not allow.
