Alacritty is a fast, cross-platform terminal emulator powered by OpenGL.
Alacritty is a modern, GPU-accelerated terminal emulator that prioritizes performance and simplicity. It is cross-platform, supporting BSD, Linux, macOS, and Windows, and focuses on being fast by leveraging OpenGL for rendering. It offers extensive configuration while avoiding feature bloat by integrating with external tools like window managers and terminal multiplexers.
Developers and power users who prioritize terminal performance, low latency, and minimal resource usage, especially those working on systems with GPU acceleration. It suits users comfortable with configuring software via text files and using external tools for features like tabs or splits.
Alacritty stands out for its emphasis on raw speed and GPU-accelerated rendering, consistently benchmarking higher throughput than many alternatives. Its design philosophy integrates with existing tools rather than reimplementing functionality, keeping it lightweight and highly configurable without unnecessary features.

Leverages OpenGL rendering for high throughput, consistently benchmarking better than competitors using vtebench, as highlighted in the FAQ's performance claims.
Runs on BSD, Linux, macOS, and Windows, offering a uniform terminal experience across major operating systems, as stated in the README's platform list.
Provides detailed customization via a TOML config file with sensible defaults, though users must create it manually, as noted in the configuration section.
Avoids feature bloat by relying on external tools like window managers and multiplexers, keeping the core minimal and focused on performance, per the README's philosophy.
Intentionally lacks tabs, splits, and a GUI config editor, requiring users to integrate external tools, which the README admits might not suit all workflows.
Does not auto-generate config files; users must create and manage TOML files in specific directories, adding setup complexity for newcomers.
Requires OpenGL ES 2.0+ and Windows 10 version 1809 or higher for ConPTY, limiting compatibility on older or resource-constrained systems.
Admits to being at a beta level with missing features and bugs, as stated in the README, which could impact reliability for critical use cases.
