The Fastest Terminal on macOS? A 14-Day Stress Test of Ghostty, Warp, and WezTerm After 14 days of intensive, real-world testing on an M3 MacBook Pro, the performance differences between modern terminal emulators are stark. Ghostty 1.0 delivers unprecedented speed—sub-5ms P50 keystroke latency and sub-100ms cold starts—while maintaining idle memory under 60 MB. However, this raw performance comes at a cost: it's the most feature-sparse option. Developers relying on AI-powered command suggestions or deep Lua extensibility will find better utility in Warp OSS or WezTerm, respectively. This isn't marketing fluff; it's data from over 2,000 individual measurements across complex workloads. The Method: Rigorous, Real-World Testing To ensure reproducibility, the test environment was meticulously controlled. A single 14-inch M3 Pro MacBook Pro with 36GB RAM ran macOS 14.5 with ProMotion locked to 120Hz.…
