## What it is
Alacritty is a fast, cross-platform terminal emulator rendered with OpenGL and written in Rust. It offers sensible defaults, extensive TOML configuration, and features like vi mode, scrollback search, and regex hints while integrating with other tools rather than reimplementing them.

## Use cases
- gpu-accelerated terminal emulator
- fast terminal for linux macos windows
- terminal emulator with vi mode and scrollback search
- lightweight terminal with toml configuration
- cross-platform terminal emulator written in rust
- terminal with regex hints and multi-window support

## When to choose
- you want a very fast, GPU-rendered terminal on Linux, BSD, macOS, or Windows
- you prefer configuring your terminal via a simple TOML file
- you spend long hours in the terminal and want vi mode, search, and regex hints
- you want a minimal emulator that delegates features like tabs to window managers or multiplexers

## When to avoid
- you need built-in tabs, splits, or ligature support out of the box
- your system lacks OpenGL ES 2.0 or, on Windows, ConPTY (Windows 10 1809+)
- you want a fully polished, feature-complete terminal rather than beta-level software

## Facets
