Rio

Rio is a terminal emulator that uses GPU hardware acceleration to deliver rendering performance on desktops and browsers. It runs on macOS, Windows, Linux, and FreeBSD, with native support for different processor architectures and installation options across platforms. The tool is written in Rust and leverages GPU acceleration technologies including Vulkan and Metal to enhance display performance. Rio is developed by raphamorim and released under the MIT license, making it available as open source software. The project is maintained with documentation, configuration guides, and a community of contributors. Installation is available through package managers, binary installers, and source compilation depending on the user's operating system.

The emulator provides features for customization and keyboard bindings, with support for multiple languages in its documentation and interface. Rio aims to modernize the terminal experience with efficient rendering capabilities powered by GPU resources rather than traditional CPU-based rendering approaches.
