Ghostty 1.0 vs Warp OSS vs WezTerm: 14 Days of Daily Use — Real Latency, Memory, and Workflow Numbers
Ghostty 1.0, Warp OSS, and WezTerm were tested over 14 days on an M3 MacBook Pro to compare performance and usability. Ghostty delivered the fastest latency and lowest memory use but lacked advanced features. Warp and WezTerm offer more functionality at the cost of higher resource usage.
- ▪Ghostty 1.0 achieved sub-5ms P50 keystroke latency and under 100ms cold start times with idle memory under 60 MB.
- ▪Warp OSS provides AI-powered command suggestions and a React-based interface, improving workflow at the expense of higher overhead.
- ▪WezTerm supports deep customization via Lua scripting but has higher memory usage and P50 latency around 15ms.
- ▪Testing involved 2,000+ measurements across real-world workloads like Vim editing, tmux panes, and log streaming.
- ▪The benchmarks were conducted on a consistent setup: an M3 Pro MacBook Pro with minimal zsh configuration to isolate terminal performance.
