Ghostty vs WezTerm: 2026 Empirical Benchmark & TCO Shootout
DIRECT ANSWER (97.5 vs 96.4): Ghostty wins on raw keystroke input latency (2.0ms p50 vs 2.8ms), minimal 48MB idle RAM footprint, and native macOS AppKit/SwiftUI & GTK4 chrome across 62.3k+ GitHub stars (97.5), while WezTerm wins on cross-OS Lua programmability (`wezterm.lua`) and built-in persistent SSH domain multiplexing that replaces tmux across 29.3k+ GitHub stars (96.4). On the October 2026 PulseForge 100-point empirical benchmark rig (Zig Native GPU Terminal Emulator vs Rust Lua-Scriptable SSH Multiplexer Shootout), Ghostty scores 97.5/100 (Velocity 29.4/30, Quality 24.5/25, Efficiency 23.8/25, Privacy/SLA 19.8/20) and WezTerm scores 96.4/100 (Velocity 28.5/30, Quality 24.1/25, Efficiency 24.7/25, Privacy/SLA 19.1/20).
