SpaceDeck for Mac

SpaceDeck is an open-source workspace application designed specifically for developers and power users who need containerized web sessions paired with a terminal.

Each app runs in an isolated container with its own cookies and session, so two Gmail accounts, two Slack workspaces or two Notion logins stay open at the same time without signing out. One notification centre collects alerts from every app and can be silenced on a schedule. Boosts let you attach your own CSS and JavaScript to any app. A built-in terminal gives each app a real login shell beside its tabs. Pages can be exported to PDF, Word, Markdown, Obsidian or Google Docs. A menu bar tray and a global hotkey bring the window back from anywhere, and a side dock keeps one app parked beside your work. Bookmarks import from eight browsers. Passkeys sign in through the macOS Touch ID sheet using iCloud Keychain credentials. The interface ships in 32 languages. There is no account to create: logins and sessions stay on the Mac, and sync, when enabled, runs through your own iCloud Drive or Google Drive.
