PureWarp

A clean terminal core stripped from Warp — no AI, no cloud, just GPU-accelerated rendering.

Lightweight, fast macOS terminal emulator rebuilt from the Warp codebase. AI, team collaboration, and telemetry removed. Only the high-performance Metal rendering engine remains.

Features

• GPU-accelerated rendering — Metal shaders draw all text directly on the GPU
• Native PTY — runs zsh, bash, or any shell via a real pseudo-terminal
• VTE-compatible — parses ANSI / VT100 / xterm escape sequences
• Scrollback — up to 1,000 lines of history, scroll with the mouse wheel
• Custom theming — TOML config file for color schemes
• No bloat — no AI, no telemetry, no sign-in, no subscription

Build

git clone https://github.com/EeroEternal/PureWarp.git
cd PureWarp
cargo build --release -p pure_warp

The binary lands at ./target/release/purewarp.

Run

cargo run --release -p pure_warp

Default window is 700×450; tweak via AddWindowOptions.
