Sidekick Browser
by PushPlayLabs Inc.
A Chromium-based work browser that organizes web apps into a sidebar, supports multiple accounts and sessions, blocks distractions, and adds productivity search and AI-assisted browsing features.
Why Abandoned
Sidekick's official website remains available and promotes downloads for its browser. Current operating details are less independently documented, so the lifecycle assessment is moderately confident.
