Fast native Windows browser without background bloat.
Built in native C# on Windows WebView2 (Chromium / Edge engine). No Python runtime, no bundled 300 MB duplicate browser binaries, full Chrome MV2/MV3 extension support, and automatic tab suspension.
Native Shell, Shared Engine
Uses Windows' built-in Edge WebView2 runtime with a ~118 KB native executable, eliminating duplicate Chromium binary overhead and delivering full V8 speed.
Automatic Tab Suspension
Inactive background tabs drop to low-memory mode and suspend via
TrySuspendAsync(), freeing CPU and RAM while keeping tabs intact.
Extensions & Userscripts
Load unpacked or .zip Chrome extensions (MV2/MV3) with toolbar popups,
plus zero-overhead custom CSS and JavaScript userscripts.
Network Ad & Tracker Blocking
Intercepts ad networks, analytics, and mining scripts inside
WebResourceRequested before requests hit the network.
Full Desktop Feature Set
Draggable tabs, pinned & muted tabs, bookmarks bar, search history, downloads manager, inline find-in-page, private windows, and DevTools (F12).
Clean Install & Uninstall
Installs per-user into %LocalAppData%\FeatherBrowser with Start Menu
shortcuts and standard Windows Uninstall registration.
