Zero Cookie-Bleed Architecture

Spaces: true isolation without profile chaos

Discover how LastBrowser strictly separates web sessions: run multiple Google, GitHub or AWS accounts side by side in the same window – without mixing cookies or history.

Classic browsers (Chrome / Edge)

Global shared state
  • ✕ All open tabs share the same cookie and session database.
  • ✕ Separation requires opening completely separate OS windows (“profile windows”).
  • ✕ Risk of accidentally posting from the wrong social-media account.
  • ✕ Heavily fragmented taskbar with 5+ open profiles.

LastBrowser Spaces

persist:profile:space
  • ✓ Full partition isolation: each Space owns a separate isolated storage partition.
  • ✓ A single window: switch Spaces quickly in the vertical sidebar.
  • ✓ Independent cookie jars: no data leakage or session spillover.
  • ✓ Memory discarding: inactive Spaces automatically free up RAM.
