DECISION GUIDE
When to pick each, and when to skip both.
Three plain-English paths: the case for Ghostty, the case for WezTerm, and the free bring-your-own-key route that avoids seat fees entirely.
When to Pick Ghostty
97.5 / 100- 62,324+ GitHub stars written in Zig by Mitchell Hashimoto with Metal (macOS) and OpenGL (Linux) GPU rendering at 2.0ms input latency
- 48MB idle RAM footprint with true platform-native window tabs, splits, and zero-config shell integration
- 100% permissive MIT license with zero cloud accounts or telemetry
When to Pick WezTerm
96.4 / 100- 29,256+ GitHub stars written in Rust with full Lua configuration scripting for custom key tables, status bars, and AI CLI triggers
- Built-in local and remote SSH multiplexer domains preserve running panes across laptop sleep/disconnects without tmux
- Identical GPU-rendered experience across macOS, Linux, Windows, and FreeBSD
When to Skip Both (BYOK OSS)
Aider / Cline- $0/mo Seat Fee: Pay pure upstream Anthropic/DeepSeek/OpenAI API rates or run local Ollama models for $0.
- Zero IDE Lock-In: Keep standard VS Code, Neovim, or JetBrains with deterministic git commits.
- 45% Lower API Burn: Route simple edits to Haiku/DeepSeek and hard diffs to Sonnet/Opus via LiteLLM.
