Vtm is a virtual terminal multiplexer delivered as a single executable that creates a text-based desktop environment bridging TUI and GUI capabilities.
The tool solves the problem of managing multiple terminal sessions and CLI applications within a unified interface. It wraps any CLI app and supports infinite nesting, allowing users to build complex text-based desktop layouts. On Windows, vtm renders directly into a native GUI window; on Unix-like systems, it operates within a terminal emulator. The tool can run in desktop mode as a full environment or in terminal mode as a standalone terminal emulator. It also supports binary connection via SSH using the DirectVT protocol for improved performance over classic connections.
Vtm suits developers and system administrators who work extensively in terminal environments and want a multiplexer that works identically across Windows, Linux, macOS, and other Unix-like systems. It is particularly valuable for those on Windows who want native GUI window rendering without relying on a separate terminal emulator. The single executable distribution makes deployment straightforward across different platforms and architectures.
The project maintains active development with regular binary releases across multiple architectures including x86_64, ARM 64-bit, and 32-bit variants for Linux, Windows, and macOS. Documentation covers architecture, building from source, command-line options, user interface customization, and advanced features like VT2D character geometry and the AnyPlex protocol. The codebase integrates established dependencies including Lua for scripting, FreeType for font rendering, HarfBuzz for text shaping, and LunaSVG for vector graphics support.
