bemenu vs PStart

bemenu is a dynamic menu library and client program inspired by dmenu. It provides the bemenu and bemenu-run clients, with build targets for curses, X11, and Wayland backends. Users can configure environment variables for options, backend selection, renderer paths, and rendering scale. The project documents default keyboard bindings and an optional Vim-style mode enabled with --binding vim. Wayland use depends on a compositor implementing the wlr-layer-shell protocol, typically a wlroots-based compositor. Clipboard pasting uses wl-paste and xclip at runtime, in that order. Building requires a C compiler, and scdoc is needed to generate the man page. The project also documents macOS build steps using Homebrew prerequisites and a build-osx.sh flow; its provided Nix expression installs only the curses backend. The client program and sources other than the library and bindings use GNU GPLv3 or later, while the library and bindings use GNU LGPLv3 or later. The project lists pinentry-bemenu as an integration. bemenu is free and open source, with no paid plans or usage limits stated.
