Warp
App Terminal
AI-powered terminal with blocks-based UI. Rust-based, GPU-accelerated.
Warp is a modern terminal built in Rust with GPU acceleration, backed by venture capital funding. It breaks from the traditional terminal paradigm with a blocks-based UI where each command and its output form a distinct visual block that can be selected, copied, and shared independently.
Warp's most distinctive feature is its AI integration — it offers command suggestions, natural language to shell translation, and inline documentation. The terminal also features a modern text editor for command input (with selection, multi-cursor, and syntax highlighting) rather than the traditional readline-style input.
Under the hood, Warp uses its own GPU-rendered terminal emulator with good standards compliance. It supports truecolor, mouse tracking, bracketed paste, and most modern escape sequences. The Rust codebase provides native performance while the GPU renderer handles smooth scrolling and high-DPI displays. Available on macOS and Linux.
