SidePanel for Browsers is a native Windows app that adds a docked side panel to your browser — pin WhatsApp, Gmail, Notion and any web app as persistent panels with their own login sessions and cloud sync.
Works with any Chromium-based browser set as your Windows default: Edge, Chrome, Brave, Opera, or Vivaldi.
100% free · Windows 10/11 (x64) · No admin rights required
Stay logged in to WhatsApp, Gmail, and any web app between restarts — each app keeps its own isolated session.
Panels run as real Windows windows anchored to your browser, with global hotkeys and proper window management.
Your pinned apps and settings sync across your PCs via Google Drive or OneDrive — set up once, use everywhere.
Every feature included — unlimited apps, folders, custom icons, themes, history. No tiers, no paywalls, no account.
