Flow Launcher
MITFlow Launcher is an open-source Windows launcher replacing Listary and Start menu search with instant file indexing and community plugins.

Overview
Volunteer developers established Flow Launcher in 2020 after the original Wox project stalled, aiming to give Windows a dependable, community-maintained productivity bar. That origin produced a launcher built on modern .NET that pairs fast file indexing with an open plugin catalog. Today it provides everyday Windows users with an instant search interface that bypasses the sluggish Start menu.
Why Flow Launcher instead of Listary
Listary focuses tightly on Windows Explorer integration, running as a compact C++ background process that hooks directly into folder windows and file dialogs. Users can begin typing inside an Explorer pane to filter files immediately, and Listary consumes less than 40 megabytes of memory. Flow Launcher approaches desktop productivity from a different angle: it operates as a floating keyboard overlay invoked by Alt+Space, combining file retrieval with an open ecosystem of community plugins for unit conversion, web queries, and application launching.
The tradeoff centers on runtime footprint and workflow scope. Listary offers unmatched speed for navigating folder trees inside native dialogs, but its proprietary development has moved slowly and its plugin architecture remains closed. Flow Launcher requires more memory—typically 90 to 150 megabytes for its .NET runtime—yet it delivers broader daily utility. By delegating disk searches to the Voidtools Everything indexing service through asynchronous background queries, Flow Launcher returns file results across millions of items without hitching the interface, while remaining free of commercial license fees.
What it does well
- Locates applications, documents, and settings within milliseconds of typing, sparing users from slow Windows Start menu searches.
- Connects directly with Voidtools Everything and Windows Search to surface files across multiple internal and external drives.
- Provides a built-in plugin store where users can install tools for currency conversion, mathematical calculations, and clipboard history with one click.
- Navigates open or save dialogs quickly using the Dialog Jump shortcut to match whatever folder is currently open in File Explorer.
- Searches web bookmarks from major browsers and triggers custom search queries directly from the keyboard bar.
- Supports extensive interface themes, dark mode matching Windows preferences, and a game mode that temporarily pauses hotkey activation.
